Hello

Are you talking about a new application to a currently configured service guard package or a new package altogether ?

To roll back, keep a copy of your package config file and package control script.

To add a service you need to halt the package, add the SERVICE_NAME to config file. Then add the same SERVICE_NAME to the package script, add the SERVICE_CMD (typically a monitoring script), and if desired the SERVICE_RESTART option (e.g. -r 2 to try 2 restarts, or -R to restart infinitely).

then run cmcheckconf -P

if this is fine run cmapplyconf -P

To roll back copy back your config and control files for the package and use the same cmcheckconf & cmapplyconf commands.

Bernhard

To prepare for rollback if necessary:
1) copy the package configuration file and package control script and cluster binary file (/etc/cmcluster/cmclconfig) for restore if needed.

To add a service to a package...
2) the following line must be added to the package configuration file (example name: pkg.config):
SERVICE_NAME

3) the following lines must be added to the package control script (example name: pkg.cntl:

SERVICE_NAME[0]=""
SERVICE_CMD[0]="SERVICE_RESTART[0]=""

4) copy the package control script to the other adoptive node(s)

5) perform "cmapplyconf -f -P pkg.config"
(cmapplyconf will update the cluster binary if the package passes the built-in cmcheckconf).

To rollback if necessary:

6) cmhaltpkg

7) copy cmclconfig.archive cmclconfig

8) copy pkg.cntl.archive pkg.cntl (on all adoptive nodes)

9) cmrunpkg

10) cp pkg.config.archive pkg.config

Stephen has it.

Just a FYI, this is a great doc on "Managing MC/ServiceGuard":
