profile representing servers and supervisors that are created in your print
environment. Any spooler or supervisor that you create is placed in the
apx-default resource. You can create additional resource profiles and move
spoolers and supervisors from the apx-default resource profile into them.
5.3.2 apx-default.scr Action Script
An action script specifies how to start the application, how to stop the
application and the clean up that occurs before the application fails over, and
how to check the application to see if it is still running.
During the Advanced Printing Software installation when the TruCluster
Server software is detected, the installation process installs the
/var/cluster/caa/script/apx-default.scr action script.
5.3.3 Registering the apx-default Resource Profile
After the resource profile and the action script are in place, you must register
the resource profile with CAA.. Use the caa_register command to register
the apx-default resource profile:
# /usr/sbin/caa_register apx-default
Once you have registered this CAA resource profile, you should use CAA
commands to start and shut down the servers. Do not use the pdsplr,
pdspvr,orpdshutdown commands.
5.3.4 Starting and Stopping the Resource Profile
After you register apx-default with CAA, you can start the resource
profile using the caa_start command:
# /usr/sbin/caa_start apx-default
When the resource starts, a message similar to the following is displayed:
Attempting to start ‘apx-default‘ on member ‘membername‘
Start of ‘apx-default‘ on member ‘membername‘ succeeded.
To stop the application, you use the caa_stop command:
# /usr/sbin/caa_stop apx-default
5.3.5 Adding Servers to the apx-default Resource Profile
After the initial servers are running in the cluster environment, you
might need to add additional spoolers and supervisors to the resource
profile. To add servers to the default resource, first you create and start
the spoolers and supervisors that you want to add. You can use the
