NAME
show - Displays current information about the DTS entity
SYNOPSIS
dtscp show attribute-group | attribute-name
ARGUMENTS
attribute-group
The name of an attribute group or individual attribute
to be displayed. The following values are valid:
+ all
+ all characteristics
+ all counters
+ all status
+ global servers
+ local servers
attribute-name
The name of a specific attribute from the characteristics,
counters, or status group. The attribute specifiers global
servers and local servers do not contain any other
attributes.
DESCRIPTION
The show command displays the names and values of the specified
attributes or attribute groups. For attribute groups, if you do
not supply a group name with the all argument, all characteristics
and their values are displayed. The following sections list names
of individual attributes, categorized by group.
Note that the attributes displayed by the show command might be
different, depending upon whether you have requested information
about a server or a clerk.
Characteristics
Characteristic arguments can contain a maximum of 80 characters
and are recalculated to a normalized date format. For example:
Input value: 0-0025:10:99.99999999
Result: 1-01:11:39.990
acting courier role

functioning as a courier. If the role is noncourier,
the node is not attempting to synchronize with global
servers. This characteristic is shown only for servers.
Default: noncourier
Value: courier or noncourier
automatic tdf change
Specifies whether automatic changes to the time
differential factor are enabled or disabled; the
value is determined by the operating system.
Default: true
Value: true/false
check interval
Specifies the amount of time between checks for faulty
servers. Applicable only to servers that have external
time providers. This characteristic is shown only for
servers.
Default: 0-01:30:00.00
Value: 0-00:00:30.000 - 10675199-02:48:05.478
clock adjustment rate
Specifies the rate at which the DTS server or clerk entity
adjusts the node's clock during a synchronization.
clock resolution
Specifies the amount of time between system clock ticks.
The value is determined by the operating system.
courier role
Specifies a server's interaction with the set of global
servers. This characteristic is shown only for servers.
backup courier
The local server becomes a courier if none are
available on the LAN.
courier The local server synchronizes with the global
set of servers.
noncourier
The local server does not synchronize with the
global set of servers.
Default: noncourier
DTS version
Specifies the DTS software version installed on the node.
epoch number
Specifies the server's epoch number. The change command
modifies this characteristic. This characteristic is
shown only for servers.
Default: 0
Value: 0-255
error tolerance
Specifies the maximum separation allowed between the
local clock and the computed time before synchronizations
become abrupt rather than gradual (monotonic).
Default: 0-00:10:00.000
Value: 0-00:00:00.500 - 10675199-02:48:05.478
global set timeout
Specifies the amount of time the node waits for a response
to a WAN synchronization request before sending another
request or declaring a global server to be unavailable.
The number of attempts made to reach the server is
controlled by the query attemps characteristic.
Default: 0-00:00:15.000
Value: 0-00:00:00.000 - 0-00:10:00.000
local set timeout
Specifies the amount of time the node waits for a response
to a synchronization request before sending another
request or declaring a server to be unavailable. The
number of attempts made to reach the server is controlled
by the query attemps characteristic.
Default: 0-00:00:05.000
Value: 0-00:00:00.000 - 0-00:10:00.000
local time differential factor
Specifies the Time Differential Factor (TDF), which is
the amount of time the server varies from Greenwich mean
time (GMT) or Coordinated Universal Time (UTC).
Default: 0-00:00:00.000
Value: -13-00:00:00 - 13-00:00:00
maximum clock drift rate
Specifies the worst-case drift rate of the node's clock,
in nanoseconds per second, as determined by the
manufacturer's specifications.
maximum inaccuracy
Specifies the inaccuracy limit for the node. When the
node exceeds the maximum inaccuracy setting, it attempts
to synchronize.
Default: 0-00:00:00.100
Value: 0-00:00:00.0 - 10675199-02:48:05.478
next tdf change
Specifies the future time at which the time differential
factor is automatically changed. The value is determined
by the operating system.

Specifies the number of attempts that a node makes to
contact a server before the node considers the server
unavailable.
Default: 3
Value: 1-10
server entry name
Specifies a server's ACL entry name; <hostname>
represents the name of the system or node that is
the server's client. The default setting is the
recommended value. This characteristic is shown only

within the cell.
Default: /.:/subsys/dce/dts-servers
server principal name
Specifies a server's principal name for authentication
purposes; <hostname> represents the name of the system
or node that is the server's client. The default setting
is the recommended value. This characteristic is shown
only for servers.
Default: /.:/hosts/<hostname>/self
servers required
Specifies the minimum number of servers required for
a synchronization. Settings of 1 or 2 may cause
unreliable computed times.
Default: 3
Value: 1-10

Also specifies synchronization frequency when a node
reaches the value specified by the maximum inaccuracy
characteristic.
