DESCRIPTIONsacadm is the administrative command for the upper level of the Service
Access Facility hierarchy (port monitor administration). sacadm per‐
forms the following functions:
o adds or removes a port monitor
o starts or stops a port monitor
o enables or disables a port monitor
o installs or replaces a per-system configuration script
o installs or replaces a per-port monitor configuration script
o prints requested port monitor information
Requests about the status of port monitors (-l and -L) and requests to
print per-port monitor and per-system configuration scripts (-g and -G
without the -z option) may be executed by any user on the system. Other
sacadm commands may be executed only by the super-user.
OPTIONS-a
Add a port monitor. When adding a port monitor, sacadm
creates the supporting directory structure in /etc/saf
and /var/saf and adds an entry for the new port monitor
to /etc/saf/_sactab. The file _sactab already exists on
the delivered system. Initially, it is empty except for a
single line, which contains the version number of the
Service Access Controller. Unless the command line that
adds the new port monitor includes the -f option with the
-x argument, the new port monitor will be started.
Because of the complexity of the options and arguments
that follow the - a option, it may be convenient to use a
command script or the menu system to add port monitors.
-c cmd
Execute the command string cmd to start a port monitor.
The -c option may be used only with a -a. A -a option
requires a -c.
-d
Disable the port monitor pmtag.
-e
Enable the port monitor pmtag.
-f dx
The -f option specifies one or both of the following two
flags which are then included in the flags field of the
_sactab entry for the new port monitor. If the -f option
is not included on the command line, no flags are set and
the default conditions prevail. By default, a port moni‐
tor is started. A -f option with no following argument is
illegal.
d
Do not enable the new port monitor.
x
Do not start the new port monitor.
-g
The -g option is used to request output or to install or
replace the per-port monitor configuration script
/etc/saf/pmtag/_config. -g requires a -p option. The -g
option with only a -p option prints the per-port monitor
configuration script for port monitor pmtag. The -g
option with a -p option and a -z option installs the
file script as the per-port monitor configuration script
for port monitor pmtag. Other combinations of options
with -g are invalid.
-G
The -G option is used to request output or to install or
replace the per-system configuration script
/etc/saf/_sysconfig. The -G option by itself prints the
per-system configuration script. The -G option in combi‐
nation with a -z option installs the file script as the
per-system configuration script. Other combinations of
options with a -G option are invalid.
-k
Stop port monitor pmtag.
-l
The -l option is used to request port monitor informa‐
tion. The -l by itself lists all port monitors on the
system. The -l option in combination with the -p option
lists only the port monitor specified by pmtag. A -l in
combination with the -t option lists all port monitors of
type type. Any other combination of options with the -l
option is invalid.
-L
The -L option is identical to the -l option except that
the output appears in a condensed format.
-n count
Set the restart count to count. If a restart count is not
specified, count is set to 0. A count of 0 indicates that
the port monitor is not to be restarted if it fails.
-p pmtag
Specifies the tag associated with a port monitor.
-r
Remove port monitor pmtag. sacadm removes the port moni‐
tor entry from /etc/saf/_sactab. If the removed port mon‐
itor is not running, then no further action is taken. If
the removed port monitor is running, the Service Access
Controller (SAC) sends it SIGTERM to indicate that it
should shut down. Note that the port monitor's directory
structure remains intact.
-s
Start a port monitor. The SAC starts the port monitor
pmtag.
-t type
Specifies the port monitor type.
-v ver
Specifies the version number of the port monitor. This
version number may be given as
-v `pmspec -V`
where pmspec is the special administrative command for
port monitor pmtag. This special command is ttyadm for
ttymon and nlsadmin for listen. The version stamp of the
port monitor is known by the command and is returned when
pmspec is invoked with a -V option.
-x
The -x option by itself tells the SAC to read its data‐
base file (_sactab). The -x option with the -p option
tells port monitor pmtag to read its administrative file.
-y comment
Include comment in the _sactab entry for port monitor
pmtag.
-z script
Used with the -g and -G options to specify the name of a
file that contains a configuration script. With the -g
option, script is a per-port monitor configuration
script; with -G it is a per-system configuration script.
Modifying a configuration script is a three-step proce‐
dure. First a copy of the existing script is made (-g or
-G). Then the copy is edited. Finally, the copy is put
in place over the existing script (-g or -G with -z).
OUTPUT
If successful, sacadm will exit with a status of 0. If sacadm fails for
any reason, it will exit with a nonzero status. Options that request
information will write the information on the standard output. In the
condensed format (-L), port monitor information is printed as a
sequence of colon-separated fields; empty fields are indicated by two
successive colons. The standard format (-l) prints a header identify‐
ing the columns, and port monitor information is aligned under the
appropriate headings. In this format, an empty field is indicated by a
hyphen. The comment character is #.
EXAMPLES
Example 1 A sample output of the sacadm command.
The following command line adds a port monitor. The port monitor tag is
npack; its type is listen; if necessary, it will restart three times
before failing; its administrative command is nlsadmin; and the config‐
uration script to be read is in the file script:
sacadm-a -p npack -t listen -c /usr/lib/saf/listen npack
-v `nlsadmin -V` -n 3 -z script
Remove a port monitor whose tag is pmtag:
sacadm-r -p pmtag
Start the port monitor whose tag is pmtag:
sacadm-s -p pmtag
Stop the port monitor whose tag is pmtag:
sacadm-k -p pmtag
Enable the port monitor whose tag is pmtag:
sacadm-e -p pmtag
Disable the port monitor whose tag is pmtag:
sacadm-d -p pmtag
List status information for all port monitors:
sacadm-l
List status information for the port monitor whose tag is pmtag:
sacadm-l -p pmtag
List the same information in condensed format:
sacadm-L -p pmtag
List status information for all port monitors whose type is listen:
sacadm-l -t listen
Replace the per-port monitor configuration script associated with the
port monitor whose tag is pmtag with the contents of the file file.con‐
fig:
sacadm-g -p pmtag -z file.config
