DCE Cell Directory Services (CDS) provide a location-independent method of identifying resources within a cell. A cell is the smallest group of DCE systems that share a common naming and security domain.
| 1 - Administration Intro |
NAME
cds_intro - Introduction to the CDS commands
DESCRIPTION
The DCE Cell Directory Service provides the following management
commands:
o The cdsbrowser command starts the CDS Browser utility. This utility
is based on the OSF/Motif graphical user interface. The Browser can
display an overall directory structure as well as show the contents
of directories.
o The nsedit command starts the CDS namespace editor utility. This
utility is based on the OSF/Motif graphical user interface. The
editor can not only display directory structure and contents, but
also allows modification of entries shown.
o The cdscp command starts the CDS control program. Use this command
line interface to manage the CDS components and the contents of your
namespace.
The following commands are typically started automatically by scripts
that execute as part of normal system start-up procedures. See the
reference pages for these commands before you try to use them.
o The cdsadv command starts the advertisement and solicitation
daemon on the local system. Use this command only when
troubleshooting because the CDS advertiser process is
normally started automatically by scripts that execute as part
of normal system start-up procedures.
o The cdsclerk command restarts the CDS clerk. Use this command
only when troubleshooting because the CDS clerk process is
normally started automatically by scripts that execute as part
of normal system start-up procedures.
o The cdsd command restarts the CDS server. Use this command only
when troubleshooting because cdsd is normally started
automatically by scripts that execute as part of normal system
start-up procedures.
o The gdad command starts the GDA (Global Directory Agent) daemon.
The GDA enables intercell communication, serving as a connection
to other cells through the global naming environment. The GDA is
typically started automatically by scripts that execute as part of
normal system start-up procedures.

NAME
cdsadv - Starts the advertisement and solicitation daemon
SYNOPSIS
cdsadv [-c] [-D] [-s] [-w route]
ARGUMENTS
-c Specifies cache size in kilobytes.
-D For debugging use only.
-s Causes the server not to send or receive advertisements.
This argument can be used for diagnostic work involving
multiple servers on the same local area network to limit
access to those servers identified with the define cached
server command.
-w route Routes serviceability messages.
DESCRIPTION
The cdsadv command starts the advertisement and solicitation daemon
on the local system.
Privilege Required
You must log in as DCE$SERVER.
NOTES
This command is ordinarily executed by the CDS startup script on the
system where the CDS server is running. You should use this command
interactively only to do diagnostic work on the host system.
EXAMPLE
To restart a clerk, enter the following command:
$ @sys$manager:dce$setup start
To debug a clerk, follow these steps:
1. Log in to the clerk system as DCE$SERVER.
2. Log in to DCE as the machine principal of the local host.
Enter the principal name in the format hosts/hostname/self
as shown in the following example command for a host named
orion whose password is smith:
$ dce_login hosts/orion/self smith
3. Enter the following command to see if the dced process is already
running:
$ show system
If the dced process appears on the list of active processes,
proceed to step 4. If the dced process does not appear on the
list of active processes, enter the following command to start
the process:
$ run sys$system:dce$dced
4. Enter the following command to start the cdsadv process:
$ run sys$system:dce$cdsadver

3.2 - DESCRIPTION
The Cell Directory Service (CDS) control program is a command line
interface for managing the components of the Cell Directory Service
and the contents of the namespace.
You can use the control program commands from within the control
program or from the system prompt. To use the control program
commands from inside the control program, start the control program
by using the cdscp command alone, without any argument. This enters
the control program, which displays the control program prompt
(cdscp>):
$ cdscp
cdscp>
At this prompt, you can enter any control program command; for example:
cdscp> show server
Use the command do filename from inside the control program to read a
file of commands.
To leave the control program and return to the system prompt, use the
quit command. To use the control program commands from the system
prompt, enter the cdscp command with an internal command of the CDS
control program as the first argument. The control program executes
the command immediately, without displaying the control program prompt.
For example, you can enter the show server command as follows:
$ cdscp show server
3. 2.1 - Elements of a CDS Command
All CDS control program commands must include a verb, an entity name, and all required arguments. Depending on the command, you can also specify optional arguments and attributes. A space must separate more than one attribute or argument. A space must precede and follow an equal sign (=).
3. 2. 1.1 - Verbs
The following is a list of the definitions of verbs used in control
program commands:
add Adds a value to a modifiable, set-valued attribute
clear Removes knowledge of a cached clearinghouse or cached
server from memory
create Creates an entity
define Creates knowledge of a locally cached server
delete Deletes an entity
disable Stops operation of a clerk or server
dump Displays the contents of a clerk cache
list Displays a list of specified entity names
remove Removes a value from a set-valued or single-valued
attribute
set Changes the value of a modifiable, single-valued
attribute
show Displays attribute information
3. 2. 1.2 - Entity Names
Any individually manageable piece of CDS is called an entity. A
set of commands exists for each entity. The following is a list of
the entities and a description of what each entity represents:
Cached Clearinghouse
A cached clearinghouse is a clearinghouse that a clerk
has discovered and cached. A clerk can learn about
clearinghouses as a result of configuration information,
advertisements received on a LAN, or during the process
of finding a name.
Cached Server
A cached server is a server that a clerk has cached as
a result of manual configuration through the control
program.
Child A child pointer connects a parent and child directory in
a hierarchical namespace. The child pointer is stored in
the parent directory and has the same name as the child
directory.
Clearinghouse
A clearinghouse is a database containing a collection of
directory replicas at a particular server.
Clerk The clerk is the interface between client applications
and servers.
Directory A directory contains child, object, and link entries that
are logically stored under one name (the directory name).
Link A soft link is a pointer providing an alternate name for
an object entry, directory, or other soft link.
Object An object entry represents a resource (for example, an
application) that is named in the namespace.
Replica A replica is a copy of a directory. Each copy, including
the original or master, is referred to as a replica.
Server A server handles lookup requests from clerks and
maintains the contents of the clearinghouse or
clearinghouses at its node.
3. 2. 1.3 - Attributes
Every CDS entity has attributes, which are pieces or sets of data associated with that entity. Attributes can reflect or affect the operational behavior of an entity, record the number of times a particular event or problem occurred since the entity was last enabled, and uniquely distinguish an entity from any other entity. Some attributes have a single value; others contain a set of values. CDS attributes are identified by ISO object identifiers (OIDs). Every CDS attribute name maps to an OID and a corresponding data type. Usually, client applications define the name of an attribute and its data type. Application programmers should never need to modify (except for the purpose of foreign language translation) the existing CDS labels associated with the unique OIDs in the cds_attributes file. However, programmers can obtain new OIDs from the appropriate allocation authority, create new attributes for their own object entries, and then append them to the existing list. The OID and data type of each attribute are stored in the file DCE$COMMON:[ETC]CDS_ATTRIBUTES.DAT. Descriptions of the CDS data types that applications can use are in the cdsclerk.h file. All entities have show commands that you can use to display the names and values of specific attributes or all attributes. When you display an attribute that has more than one value, the show command lists each value for the attribute separately. When there are multiple values for an attribute, the command first lists the attribute name on a line ending with a colon, then the parts of the value. For more information about CDS attributes, see the DCE Directory Service module in the DCE Administration Guide.
3. 2.2 - Editing the Commands
You can abbreviate commands, continue a command beyond one line, or
redirect output to a file within the control program.
To abbreviate any command name, type only the first four characters.
You can abbreviate a command name to fewer than four characters as
long as the abbreviated name remains unique among all command names
in the control program. For example, the following commands are
equivalent:
cdscp> show directory /.:/sales
cdscp> sh dir /.:/sales
To continue a long command line onto the next line, type a space and
then a \ (backslash) at the end of the first line, for example:
cdscp> set link /.:/sales CDS_LinkTimeout \
> (1991-12-31-12:00:00 090-00:00:00)
To add a comment, use the # (number sign). Everything following the
# character on a line is ignored.
3. 2.3 - Using Wildcard Characters
When entering a name in show and list commands, you can use wildcard characters in the rightmost simple name (the name to the right of the last slash (/) in the full pathname). The asterisk (*) matches 0 or more characters in a simple name. The question mark (?) matches exactly one character in a simple name. When you use an asterisk or a question mark as a normal character in the rightmost simple name of a show or list command, escape it with a backslash (\* or \?). Otherwise, the character is interpreted as a wildcard. You cannot use wildcard characters in show clerk and show server commands.
3. 2.4 - Permissions Required
CDS supports the following DCE permissions: read (r), write (w),
insert (i), delete (d), test (t), control (c), and administer (a).
Each permission has a slightly different meaning, depending on the
kind of CDS name with which it is associated. In general, the
permissions are defined as follows:
Read Allows a principal to look up a name and view the attribute
values associated with it.
Write Permission allows a principal to change the modifiable
attributes associated with a name, except the name's
access control list (ACL) entries.
Insert Permission (for use with directory entries only) allows a
principal to create new names in a directory.
Delete Permission allows a principal to delete a name from the
namespace.
Test Permission allows a principal to test whether an attribute
of a name has a particular value without being able to
actually see any of the values (that is, without having
read permission to the name).
Test permission provides application programs a more
efficient way to verify a CDS attribute value. Rather
than reading an entire set of values, an application can
test for the presence of a particular value.
Control Permission allows a principal to modify the ACL entries
associated with a name. (Note that read permission is
also necessary for modifying a CDS entry's ACLs; otherwise,
acl_edit will not be able to bind to the entry.) Control
permission is automatically granted to the creator of a CDS
name.
Administer
Permission (for use with directory entries only) allows a
principal to issue CDS control program commands that
control the replication of directories.
The creator of a name is automatically granted all permissions
appropriate for the type of name created. For example, a principal
creating an object entry is granted read, write, delete, test, and
control permission to the object entry. A principal creating a
directory is granted read, write, insert, delete, test, control,
and administer permission to the directory.
3.3 - EXAMPLES
The following command starts the CDS control program:
$ cdscp
cdscp>
The following command operates from the system prompt to display the
attributes of the CDS clerk on the local system:
$ cdscp show clerk
3.4 - add_directory
NAME
add directory - Adds a value to a modifiable, set-valued attribute
(including application-defined attributes) of a
directory
SYNOPSIS
cdscp add directory directory-name attribute-name = attribute-value
ARGUMENTS
directory-name
The full name of the directory.
attribute-name
The name of a particular attribute. Specify only one
attribute at a time. See the cds_attributes file for
the list of attributes that your application uses.
attribute-value
The value of a particular attribute. The value of an
application-defined attribute is dependent on the type of
attribute. See the cds_attributes file for the list of
attributes and corresponding data types that your
application uses. If you enter a byte data type, you
must enter an even number of digits in length. You can
only enter pairs of hexadecimal values for user-defined
attributes.
DESCRIPTION
The add directory command adds a value to a modifiable, set-valued
attribute (including application-defined attributes) of a directory.
If the attribute does not exist, this command creates it. Usually,
this task is performed through the client application. See the DCE
Administration Guide for more information about attributes.
Privilege Required
You must have write permission to the directory.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLE
To add the value ontario to the attribute myname of a directory
named /.:/sales, read the cds_attributes file to verify that the
attribute shown in the following display exists:
OID LABEL SYNTAX
1.3.22.1.3.91 myname char
Enter the following command to assign the value ontario to the
attribute myname:

application-defined attribute is dependent on the type
of attribute.
DESCRIPTION
The add object command adds a value to a modifiable, set-valued
attribute (including application-defined attributes) of an object
entry. If the attribute does not exist, this command creates it.
Usually, this task is performed through the client application.
See the DCE Administration Guide for more information about
attributes.
Privilege Required
You must have write permission to the object entry.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.

NAME
clear cached server - Removes knowledge of a server that you had
specifically defined from the local clerk's
cache
SYNOPSIS
cdscp clear cached server name
ARGUMENTS
name The simple name given to the cached server when it
is created.
DESCRIPTION
The clear cached server command removes knowledge of a server from
the local clerk's cache. You can only clear servers that you have
specifically created with the define cached server command.
Privilege Required
You must have write permission to the clerk.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLES
The following command removes knowledge of the server nrl from the
clerk cache:
cdscp> clear cached server nrl
RELATED INFORMATION
Commands: define cached server
dump clerk cache
show cached server
3.7 - clear_clearinghouse
NAME
clear clearinghouse - Removes knowledge of the specified
clearinghouse from the server's memory
SYNOPSIS
cdscp clear clearinghouse clearinghouse-name
ARGUMENTS
clearinghouse-name The full name of the clearinghouse.
DESCRIPTION
The clear clearinghouse command removes knowledge of the specified
clearinghouse from the server's memory. The clearinghouse files
are not deleted. This ensures that the clearinghouse is not
automatically enabled on server restarts. If you issue a list
clearinghouse command, the clearinghouse will be listed.
Before you can delete a cleared clearinghouse, you must use the
create clearinghouse command to recreate it. After recreating
the clearinghouse, you can use the delete clearinghouse command
to remove it.
This command is part of the process of relocating a clearinghouse.
See the OSF DCE Administration Guide for more information.
Privilege Required
You must have write permission to the server on which the
clearinghouse resides.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLES
The following command clears the clearinghouse /.:/Paris2_CH before
moving it to another server:
cdscp> clear clearinghouse /.:/Paris2_CH

3.8 - create_child
NAME
create child - Creates a child pointer at the master replica of
the parent directory
SYNOPSIS
cdscp create child child-name clearinghouse clearinghouse-name
ARGUMENTS
child-name
The full name of the child pointer.
clearinghouse-name
The full name of a clearinghouse that contains a replica
of the child directory.
DESCRIPTION
The create child command creates a child pointer at the master
replica of the parent directory. When CDS looks up a name in the
namespace, it uses child pointers to locate directory replicas.
Use the set cdscp preferred clearinghouse command before issuing
this command to ensure that the request is directed to the master
replica.
Privilege Required
You must have insert permission to the parent directory.
NOTES
Use the create child command only to re-create a child pointer
that is accidentally deleted. This command is designed only for
troubleshooting.
This command will fail if the associated directory does not exist.
If the associated directory exists, this command will return
successfully.
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLE
The following command creates the child pointer in the parent
directory /.:/subsys. It uses the replica located at the
/.:/subsys/NY_CH clearinghouse to fill in its replica set.
cdscp> create child /.:/subsys clearinghouse /.:/subsys/NY_CH
RELATED INFORMATION
Commands: delete child
list child
show child
3.9 - create_clearinghouse
NAME
create clearinghouse - Creates a clearinghouse on the local server
system or makes an existing clearinghouse
available
SYNOPSIS
cdscp create clearinghouse clearinghouse-name
ARGUMENTS
clearinghouse-name
The full name of the clearinghouse.
DESCRIPTION
The create clearinghouse command creates a clearinghouse on the
local server system or makes an existing clearinghouse available.
The server start-up command usually creates a new clearinghouse
when you configure a new CDS server. Occasionally, you may need to
create a second clearinghouse on a particular server; for example,
if you are temporarily relocating a clearinghouse on a different
server. See the OSF DCE Administration Guide for more information
about relocating a clearinghouse.
Clearinghouses should be named only in the root. When you enter the
command, CDS creates a read-only replica of the root directory and
stores it in the new clearinghouse as the initial replica. Because
the process that creates the new clearinghouse initiates a skulk of
the root directory, all replicas of the root should be reachable when
you enter the command.
Privilege Required
You need write permission to the server on which you intend to create
the clearinghouse and administer permission to the cell root directory.
The server principal needs read, write, and administer permission to
the cell root directory.
NOTES
This command is usually executed only by the network configuration
procedure. To ensure that all replicas of the root are reachable,
perform an immediate skulk of /.: prior to issuing this command.
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLE
The following command creates a clearinghouse named /.:/Boston_CH
on the local server system:
cdscp> create clearinghouse /.:/Boston_CH

3.10 - create_directory
NAME
create directory - Creates a directory
SYNOPSIS
cdscp create directory directory-name [clearinghouse clearinghouse-name]
ARGUMENTS
directory-name
The full name of the directory
clearinghouse-name
The name of the clearinghouse in which you create the
directory.
DESCRIPTION
The create directory command creates a directory with the name that
you specify. If you do not specify a clearinghouse, CDS creates the
master replica of the directory in the same clearinghouse as the new
directory's parent directory.
Privilege Required
You must have the following permissions in order to create a directory:
+ read and insert permission to the parent directory;
+ write permission to the clearinghouse in which the master replica
of the new directory is to be stored.
In addition, the server principal must have read and insert permission
to the parent directory.
NOTES
To ensure that all replicas are consistent, perform an immediate
skulk of the parent directory after issuing this command.
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLE
The following command creates a directory named /.:/sales.
cdscp> create directory /.:/sales

3.11 - create_link
NAME
create link - Creates a soft link and optionally specifies an
expiration time and an extension time
SYNOPSIS
cdscp create link link-name CDS_LinkTarget = target-name
[CDS_LinkTimeout = (expiration-time extension-time)]
ARGUMENTS
link-name The full name of the soft link.
target-name
The full name of the entry to which the soft link points.
expiration-time
A date and time after which CDS checks for existence of
the soft link's target and either extends or deletes the
soft link. The value is specified as yyyy-mm-dd-hh:mm:ss
(year-month-day-hour:minute:second). You can abbreviate
this value.
extension-time
A period of time by which to extend the soft link's
expiration time (if the server has validated that the
target still exists). The value is specified as
ddd-hh:mm:ss (days-hour:minute:second). You can
abbreviate this value.
DESCRIPTION
The create link command creates a soft link. If you specify the
CDS_LinkTimeout attribute, you must specify an expiration time and
an extension time. If you omit the CDS_LinkTimeout attribute, the
soft link is permanent and must be explicitly deleted.
Privilege Required
You must have insert permission to the directory in which you intend
to create the soft link.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLE
The following command creates a permanent soft link named
/.:/sales/tokyo/price-server that points to an object entry named
/.:/sales/east/price-server. The expiration value indicates that
CDS will check that the destination name /.:/sales/east/price-server
still exists on June 25,1995, at 12:00 p.m. If the destination name
still exists, the soft link remains in effect another 90 days.
Thereafter, CDS will check that the destination name exists every 90
days.
cdscp> create link /.:/sales/tokyo/price-server CDS_LinkTarget \
> = /.:/sales/east/price-server CDS_LinkTimeout = \
> (1995-06-25-12:00:00 = 90-00:00:00)

3.12 - create_object
NAME
create object - Creates an object entry
SYNOPSIS
cdscp create object object-name [CDS_Class = class-name
CDS_ClassVersion = value]
ARGUMENTS
object-name
The full name of the object entry.
class-name
The class of object entry being created. You can specify
an application-defined class name. A class is specified
as a simple name limited to 31 characters.
value The version of the class assigned to the object entry.
Specify the value as v.n, where v defines the major
release number and n specifies the minor version number.
Specifying a class version is useful as it allows the
definition of a class to evolve as the application is
revised.
DESCRIPTION
The create object command creates an object entry. This task is
usually done through a client application.
Privilege Required
You must have insert permission to the parent directory.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLE
The following command creates an object entry named
/.:/sales/east/floor1cp. The object entry describes a color printer
on the first floor of a company's eastern sales office.

DESCRIPTION
The create replica command creates a replica of an existing directory
in the specified clearinghouse.
Privilege Required
You must have administer permission to the directory you intend to
replicate and write permission to the clearinghouse that stores the
new replica. The server principal needs read, write, and administer
permission to the directory you intend to replicate.
NOTES
This command is usually executed only by the network configuration
procedure. To ensure that all replicas are consistent, perform an
immediate skulk of the parent directory after issuing this command.
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLE
The following command creates a replica of the /.:/mfg directory
in the clearinghouse /.:/Paris_CH.

3.14 - define_cached_server
NAME
define cached server - Creates knowledge of a server in the local
clerk's cache
SYNOPSIS
cdscp define cached server name tower value
ARGUMENTS
name A simple name for the cached server.
value The protocol sequence and network address of the server node.
The format is protocol-sequence:network-address. A protocol-
sequence is a character string identifying the network
protocols used to establish a relationship between a client
and server. There are two choices of protocol sequence,
depending on the network address that is supplied in the
binding: ncacn_ip_tcp or ncadg_ip_udp. For the network-
address, specify an Internet address using the common
Internet address notation. For more information about this
format, see the RPC introduction in the DCE Application
Development Reference.
DESCRIPTION
The define cached server command creates knowledge of a server in the
local clerk's cache. This command is typically used to manually
provide configuration information to a clerk that cannot automatically
configure itself. This is required, for instance, to give the clerk
addressing information about a server across a WAN. Once the clerk
knows about one server, it can find other servers through referrals.
Privilege Required
You must have write permission to the clerk.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLES
The following command creates knowledge of the server nrl in the
local clerk's cache:
cdscp> define cached server nrl tower ncacn_ip_tcp:16.20.15.25

3.16 - delete_clearinghouse
NAME
delete clearinghouse - Deletes the specified clearinghouse from the
local server system
SYNOPSIS
cdscp delete clearinghouse clearinghouse-name
ARGUMENT
clearinghouse-name
The full name of the clearinghouse.
DESCRIPTION
The delete clearinghouse command deletes a clearinghouse from the
local server system. CDS does not permit you to delete a cleared
clearinghouse. Before you can delete a cleared clearinghouse, you
must recreate it using the create clearinghouse command.
The delete clearinghouse command automatically deletes all read-only
replicas from a clearinghouse. CDS does not permit you to delete a
clearinghouse that contains a master replica. See the DCE Directory
Service module of the DCE Administration Guide for more information
about handling master replicas when deleting a clearinghouse.
Permissions Required
You must have write and delete permission to the clearinghouse and
administer permission to all directories that store replicas in the
clearinghouse. The server principal needs delete permission to the
associated clearinghouse object entry and administer permission to
all directories that store replicas in the clearinghouse.
NOTES
It is recommended that you delete all replicas except the root before
issuing this command.
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLE
The following command deletes a clearinghouse named /.:/sales/Orion_CH
from the local server system:

3.32 - set_cdscp_confidence
NAME
set cdscp confidence - Sets the confidence level of clerk calls issued
as a result of CDS control program commands
SYNOPSIS
cdscp set cdscp confidence = value
ARGUMENTS
value One of the following confidence levels: low, medium, or
high. A low confidence level means the clerk obtains
information from caches or the most convenient server.
A medium level means the clerk obtains information directly
from a server. A high level means the clerk obtains
information only at master replicas. The initial value is
medium.
DESCRIPTION
The set cdscp confidence command sets the confidence level of clerk
calls issued as a result of CDS control program commands. You must
use this command within the CDS control program. Exiting from the
CDS control program removes the confidence level setting. You must
reset the confidence level each time you enter the CDS control program.
NOTE
This command may be replaced in future releases by the dcecp command,

that result from CDS control program
commands
SYNOPSIS
cdscp set cdscp preferred clearinghouse [clearinghouse-name]
ARGUMENTS
clearinghouse-name
The full name of the preferred clearinghouse. If you omit
this argument, the command causes CDS to revert to the
default, which is to use any clearinghouse.
DESCRIPTION
The set cdscp preferred clearinghouse command specifies a preferred
clearinghouse to use for satisfying read requests that result from CDS
control program commands. You cannot specify a preferred clearinghouse
for making modifications, because these requests always use the master
replica. You must use this command within the CDS control program.
Exiting from the CDS control program removes the preferred clearinghouse
setting. You must reset the preferred clearinghouse each time you enter
the CDS control program.
Permissions Required
None
NOTE
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.

3.34 - set_directory
NAME
set directory - Changes the value of a modifiable, single-valued
attribute of a directory
SYNOPSIS
cdscp set directory directory-name attribute-name = attribute-value
ARGUMENTS
directory-name
The full name of the directory.
attribute-name
The name of a particular attribute. Specify only one
attribute at a time. See the cds_attributes file for the
list of attributes and corresponding data types that your
application uses.
attribute-value
The value of a particular attribute. The value of an
application-defined attribute is dependent on the type of
attribute.
DESCRIPTION
The set directory command changes the value of a modifiable,
single-valued attribute of a directory. If the attribute does not
exist, this command creates it. Usually, this task is performed
through the client application. See the OSF DCE Administration
Guide for more information about attributes. You can specify an
application-defined attribute or the following attributes:
CDS_Convergence = value
Specifies the degree of consistency among replicas. By
default, every directory inherits the convergence of its
parent at creation time. The default setting on the root
directory is medium. You can define one of the following
for value:
low CDS does not immediately propagate any updates.
The next skulk distributes all updates that
occurred since the previous skulk. Skulks occur
at least once every 24 hours.
medium CDS attempts to immediately propagate an update to
all replicas. If the attempt fails, the software
lets the next scheduled skulk make the replicas
consistent. Skulks occur at least once every 12
hours.
high CDS attempts to immediately propagate an update to
all replicas. If that attempt fails (for example,
if one of the replicas is unavailable), a skulk is
scheduled for within one hour. Background skulks
occur at least once every 12 hours. Use this
setting temporarily and briefly because it uses
extensive system resources.
CDS_UpgradeTo = v.n
Controls the upgrading of a directory from one version of
CDS to another. By modifying this attribute, you can
initiate the upgrading of a directory to a higher version
of CDS. Specify the value as v.n, where v indicates the
major version number and n specifies the minor version
number. There is no default.
Privilege Required
You must have write permission to the directory.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLES
The following command sets a low convergence value on the /.:/mfg
directory:

3.35 - set_directory_to_new_epoch
NAME
set directory to new epoch - Reconstructs a directory's replica set,
allowing you to designate a new master
replica or to exclude a replica
SYNOPSIS
cdscp set directory directory-name to new epoch master
clearinghouse-name
[readonly clearinghouse-name...]
[exclude clearinghouse-name...]
ARGUMENTS
directory-name
The full name of the directory.
master clearinghouse-name ...
The full name of the clearinghouse in which an individual
replica is located. The first clearinghouse-name specifies
where the master replica is stored.
readonly clearinghouse-name ...
Designates the replicas in the specified clearinghouses as
read-only.
exclude clearinghouse-name ...
Excludes the replicas in the specified clearinghouses.
DESCRIPTION
The set directory to new epoch command reconstructs a directory's
replica set, allowing you to designate a new master replica or to
exclude a replica. You must list each existing replica and indicate
whether an existing replica needs to be included in or excluded from
the new replica set. You can include or exclude more than one
replica. The ellipses (...) indicates that you can specify multiple
clearinghouse names, separated by spaces.
When you set a new epoch on a directory, you must disable the
clearinghouse containing the replica that is being excluded. To do
this, use the disable server command (if the server has more than
one clearinghouse, all its clearinghouses will be disabled). Note
that all clearinghouses that are not excluded must be enabled and
available before you issue the disable server command.
Privilege Required
You must have administer permission to the directory, and the
server principal needs administer, read, and write permission to
the directory. When designating a new master replica, you also
need write permission to the clearinghouse that stores the new
master replica, and the server principal needs write permission
to each clearinghouse where the replica type is changed to read-only.
NOTE
This command may be replaced in future releases by the dcecp command,
and may no longer be supported at that time.
EXAMPLE
The following command sets a new epoch for the directory /.:/mfg. The
master replica is in the clearinghouse /.:/Paris1_CH, and read-only
replicas are in the clearinghouses /.:/Chicago1_CH, /.:/Seattle_CH,
and /.:/NY1_CH. The new replica set excludes the replica in the
clearinghouse /.:/NY1_CH.

3.43 - show_cell
NAME
show cell - Displays the information you need to create a cell entry
in either DNS or GDS
SYNOPSIS
cdscp show cell cell-name [as type]
ARGUMENTS
cell-name The global name of the cell.
type The global namespace in which you want to define the cell.
Enter either of the values dns or gds. The default is gds.
DESCRIPTION
The show cell command displays the information you need to create a
cell entry in either the Domain Name System (DNS) or the Global
Directory Service (GDS). DCE does not support cells registered
simultaneously in GDS and DNS. If you want to define a cell in DNS,
you can use this command to produce a preformatted set of resource
records. You can then edit the appropriate DNS data file and copy
the output directly into the file. In GDS, cell information is
contained in two attributes: CDS-Cell and CDS-Replica. If you want
to define a cell in GDS, you can use this command to obtain the data
you need to supply when creating the CDS-Cell and CDS-Replica
attributes. For details, see the OSF DCE Administration Guide.
Privilege Required
You must have read permission to the cell root directory.
NOTE
This command may be replaced in future releases by the dcecp command,

3. 47.1 - DESCRIPTION
The show directory command displays the names and values of the
attributes specified in attribute-name. You can use a combination
of attributes in any sequence in a single command. Use a space to
separate multiple attributes. You can use a with
attribute-name = attribute-value clause to limit output only to
directories whose attributes have values equal to the specified
values. A space must precede and follow the = (equals sign). If
you do not supply any attributes, the command displays all
attributes and their values. In addition to the following
directory attributes, application-specific attributes can exist for
a directory:
CDS_AllUpTo
Indicates the date and time of the last successful skulk on
the directory. All replicas of the directory are guaranteed
to receive all updates whose timestamps are less than the
value of this attribute.
CDS_Convergence
Specifies the degree of consistency among replicas. This
attribute's value is defined as one of the following:
low CDS does not immediately propagate an update.
The next skulk distributes all updates that
occurred since the previous skulk. Skulks
occur at least once every 24 hours.
medium CDS attempts to immediately propagate an update
to all replicas. If the attempt fails, the next
scheduled skulk makes the replicas consistent.
Skulks occur at least once every 12 hours.
high CDS attempts to immediately propagate an update
to all replicas. If the attempt fails (for
example, if one of the replicas is unavailable),
a skulk is scheduled for within one hour. Skulks
usually occur at least once every 12 hours. Use
this setting temporarily and briefly, because it
uses extensive system resources.
By default, every directory inherits the convergence setting of its
parent at creation time. The default setting on the root directory
is medium.
CDS_CTS Specifies the creation timestamp (CTS) of the CDS
directory.
CDS_DirectoryVersion
Specifies the minimum of all the values of the
CDS_ReplicaVersion attribute on the directory replicas.
CDS_Epoch A UUID that identifies a particular incarnation of the
directory.
CDS_LastSkulk
Records the timestamp of the last skulk performed on this
directory.
CDS_LastUpdate
Records the timestamp of the most recent change to any
attribute of a directory replica, or any change to an entry
in the replica.
CDS_ObjectUUID
Specifies the unique identifier of the directory.
CDS_ParentPointer
Contains a pointer to this directory's parent in the
namespace.
CDS_Replicas
Specifies the address, UUID, and name of every
clearinghouse where a copy of this directory is
located. This attribute also specifies whether the
replica in a particular clearinghouse is a master
or read-only replica.
CDS_ReplicaState
Specifies whether a directory replica can be accessed.
CDS_ReplicaType
Indicates whether a directory replica is a master or
read-only replica.
CDS_ReplicaVersion
Specifies the version of a replica of the directory.
CDS_RingPointer
Specifies the UUID of a clearinghouse containing another
replica of this directory. This attribute is written by
the system and is read-only to users. It will appear on
older directories, but not on DCE 1.1 directories.
CDS_UpgradeTo
Controls the upgrading of a directory from one version of
CDS to another. By modifying this attribute, you can
initiate the upgrading of a directory to a new version of
CDS.
CDS_UTS Specifies the timestamp of the most recent update to an
attribute of the directory.
RPC_ClassVersion
Specifies the RPC runtime software version that can be used
to import on the directory.
Privilege Required
You must have read permission to the directory. If you specify
a wildcard directory name, you also need read permission to the
directory's parent directory.

3.49 - show_object
NAME
show object - Displays attribute information about the specified
object entry
SYNOPSIS
cdscp show object object-name [attribute-name]
[with attribute-name = attribute-value]
ARGUMENTS
object-name
The full name of a specific object entry. The last simple
name can contain wildcard characters.
attribute-name
The name of a particular attribute; see Description for
valid attribute names.
attribute-value
The value of a particular attribute.
DESCRIPTION
The show object command displays the names and values of the attributes
specified in attribute-name. You can use a combination of attributes
in a single command. Use a space to separate multiple attributes.
You can use a with attribute-name = attribute-value clause to limit
output only to object entries whose attributes have values equal to
the specified values. If you do not supply any attributes, the
command displays all attributes and their values. In addition to the
following attributes, any application-defined attributes that might
exist will be included in the output of this command. The following
is a description of object entry attributes:
CDS_Class Specifies the class to which an object belongs.
CDS_ClassVersion
Contains the version number of the object's class. This
allows applications to build in compatibility with entries
created by earlier versions.
CDS_CTS Specifies the creation timestamp (CTS) of this object entry.
CDS_ObjectUUID
Specifies a unique identifier for the object being
referenced.
CDS_UTS Specifies the timestamp of the most recent update to an
attribute of the object entry.
Privilege Required
You must have read permission to the object entry. If you specify
a wildcard object entry name, you also need read permission to the
directory that stores the object entry.
NOTE
This command is replaced at Revision 1.1 by the dcecp command and
may not be provided in future releases of DCE.
EXAMPLE
The following command lists all the attributes and their values of
the object entry /.:/sales/east/floor1cp.
cdscp> show object /.:/sales/east/floor1cp

3. 50.1 - DESCRIPTION
The show replica command displays the directory-specific attributes
as well as the per-replica attributes of the specified directory. If
you do not supply any attributes, the command displays all attributes
and their values; any application-defined attributes that might exist
will be included in the output of this command. You can enter one or
more of the following attributes:
CDS_AllUpTo
Indicates the date and time of the last successful skulk on
the directory. All replicas of the directory are guaranteed
to have received all updates whose timestamps are less than
the value of this attribute.
CDS_Convergence
Specifies the degree of consistency among replicas. This
attribute's value is defined as one of the following:
low CDS does not immediately propagate an update.
The next skulk distributes all updates that
occurred since the previous skulk. Skulks occur
at least once every 24 hours.
medium CDS attempts to immediately propagate an update
to all replicas. If the attempt fails, the next
scheduled skulk makes the replicas consistent.
Skulks occur at least once every 12 hours.
high CDS attempts to immediately propagate an update
to all replicas. If the attempt fails (for
example, if one of the replicas is unavailable),
a skulk is scheduled for within one hour.
Skulks usually occur at least once every 12 hours.
Use this setting temporarily and briefly, because
it uses extensive system resources.
By default, every directory inherits the convergence setting of its
parent at creation time. The default setting on the root directory is
medium.
CDS_CTS Specifies the creation timestamp (CTS) of the directory of
which this replica is a copy.
CDS_DirectoryVersion
Specifies the minimum of all the values of the
CDS_ReplicaVersion attribute on the directory replicas.
CDS_Epoch A UUID that identifies a particular incarnation of the
directory.
CDS_LastSkulk
Records the timestamp of the last skulk performed on this
particular replica of a directory.
CDS_LastUpdate
Records the timestamp of the last update to any attribute
of the replica, or any change to the contents of the
replica, including object entries, child pointers, and soft
links.
CDS_ObjectUUID
Specifies the unique identifier of the directory of which
this replica is a copy.
CDS_ParentPointer
Contains a pointer to this directory's parent in the
namespace.
CDS_Replicas
Specifies the address, UUID, and name of every
clearinghouse where a replica of this directory is
located. This attribute also specifies whether the
replica in a particular clearinghouse is a master or
read-only replica.
CDS_ReplicaState
Specifies the internal state of a replica. When you create
or delete a replica, it goes through various states.
CDS_ReplicaType
Specifies the replica type of a directory.
CDS_ReplicaVersion
Specifies the replica version of a directory.
CDS_RingPointer
Specifies the UUID of a clearinghouse containing another
replica of this directory. This attribute is written by
the system and is read-only to users. It will appear on
older directories, but not on DCE 1.1 directories.
CDS_UTS Specifies the timestamp of the most recent update to an
attribute of the directory.
RPC_ClassVersion
Specifies the RPC runtime software version that can be used
to import on the directory.
Privilege Required
You must have read permission to the directory from which the replica
is created.
3. 50.2 - EXAMPLE
The following command displays the current values of all the
attributes of the replica of the /.:/eng directory in the
/.:/Chicago2_CH clearinghouse:

3.51 - show_server
NAME
show server - Displays attribute information about the server running
on the local system
SYNOPSIS
cdscp show server
DESCRIPTION
The show server command displays all the names and values from the
attributes named in this entity. The server must be enabled when
you use this command. The following are valid attribute names:
Child Update Failures
Specifies the number of times the server was unable to
contact all the clearinghouses that store a replica of
a particular child directory's parent directory and apply
the child updates that have occurred since the last skulk.
This counter is incremented by the Cannot Update Child
Pointer event.
Creation Time
Specifies the time when the CDS control program process was
started.
Crucial Replicas
Specifies the number of times a user attempted (from this
server) to remove a replica that is crucial to the
connectivity of a directory hierarchy. The server
background process prevents users from accidentally
disconnecting lower-level directories from higher-level
directories. When it detects an attempt to remove a
crucial replica, it does not execute the command to do so.
This counter is incremented by the Crucial Replica event.
Future Skew Time
Specifies the maximum amount of time that a timestamp on a
new or modified entry can vary from local system time at the
server system.
Known Clearinghouses
Specifies the clearinghouse or clearinghouses known to the
server.
Read Operations
Specifies the number of read operations directed to this CDS
server.
Security Failures
Specifies the number of times a server principal for this
server was found to have inadequate permissions to perform
a requested operation.
Skulks Completed
Specifies the number of skulks successfully completed by
this CDS server.
Skulks Initiated
Specifies the number of skulks initiated by this CDS
server.
Times Lookup Paths Broken
Specifies the number of broken connections between
clearinghouses on this server and clearinghouses closer to
the root. Incoming requests to this server that require a
downward lookup in the directory hierarchy still succeed,
but requests that require a lookup in directories closer to
the root will fail. This counter is incremented by the
Broken Lookup Paths event.
Write Operations
Specifies the number of write operations to this CDS server.
Privilege Required
You must have read permission to the server.
NOTE
This command may be replaced in future releases by the dcecp command,
and may no longer be supported at that time.
EXAMPLE
The following command displays the current values of all the
attributes associated with the server running on the local system:
cdscp> show server

NAME
cdsbrowser - Starts the CDS Browser utility on the local system
SYNOPSIS
cdsbrowser
DESCRIPTION
The cdsbrowser command starts the CDS Browser utility on the local
system. This utility runs on workstations with windowing software
based on the OSF/Motif graphical user interface. Using a mouse to
manipulate pull-down menus, you can view the directory structure of
a namespace, view child directories of a particular directory, view
the object entries and soft links in a directory, and set a filter to
display only object entries of a particular class. (For users who do
not have windowing software, similar functions are available with the
control program.) When you use the CDS Browser, it sets the confidence
level of clerk calls to low.
Privilege Required
None
EXAMPLE
The following command starts the CDS Browser utility on the local
system:
$ cdsbrowser
If the cdsbrowser command is not currently defined, execute the following
command file, and try again:
