Managing HP Serviceguard for Linux Ninth Edition, April 2009

service_fail_fast_enabled no
service_halt_timeout 300
See the package configuration template file for more examples.
For legacy packages, this parameter is in the package control script as well as the
package configuration file.
service_cmd
The command that runs the program or function for this service_name, for example,
/usr/bin/X11/xclock -display 15.244.58.208:0
An absolute pathname is required; neither the PATH variable nor any other environment
variable is passed to the command. The default shell is /bin/sh.
NOTE: Be careful when defining service run commands. Each run command is
executed in the following way:
• The cmrunserv command executes the run command.
• Serviceguard monitors the process ID (PID) of the process the run command
creates.
• When the command exits, Serviceguard determines that a failure has occurred
and takes appropriate action, which may include transferring the package to an
adoptive node.
• If a run command is a shell script that runs some other command and then exits,
Serviceguard will consider this normal exit as a failure.
Make sure that each run command is the name of an actual service and that its process
remains alive until the actual service stops. One way to manage this is to configure a
package such that the service is actually a monitoring program that checks the health
of the application that constitutes the main function of the package, and exits if it finds
the application has failed. The application itself can be started by an external_script
(page 212).
This parameter is in the package control script for legacy packages.
service_restart
The number of times Serviceguard will attempt to re-run the service_cmd. Valid values
are unlimited, none or any positive integer value. Default is none.
If the value is unlimited, the service will be restarted an infinite number of times. If
the value is none, the service will not be restarted.
This parameter is in the package control script for legacy packages.
