DESCRIPTION
sacadm is the administrative command for the upper level of
the Service Access Facility hierarchy (port monitor adminis-
tration). sacadm performs 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 configura-
tion scripts (-g and -G without the -z option) may be exe-
cuted 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 moni-
tor 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 moni-
tor 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 moni-
tor. 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 monitor 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 con-
figuration script for port monitor pmtag. Other combi-
nations 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
combination with a -z option installs the file script
as the per-system configuration script. Other combina-
tions 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 indi-
cates 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
monitor entry from /etc/saf/_sactab. If the removed
port monitor 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
database file (_sactab). The -x option with the -p
option tells port monitor pmtag to read its adminis-
trative 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 procedure. 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
identifying 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 configuration 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.config:
sacadm -g -p pmtag -z file.config
