This is a script I wrote to automate the restart of GroupWise 8 sp1 services on our SLES11 server. Frequently the grpwise and gwmta services would fail on the server. Restarting the services manually in the middle of the night got old fast. This script will check the grpwise and gwmta services to see if they are running or not. If not it will be logged, restarted, checked for completion, logged and if it fails, logged again.

This script could be easily modified to include other services like webaccess, apache, tomcat, and the gwia. This script uses two methods for finding the running service/process. grpwise services does not run with a PID so the method for finding if the service is running is different than finding the gwmta process, take note.

You can download the script as well. Rename file to have .sh extension. Upload to server the as root then chmod u x <script_name>.sh to make the script executable. Edit crontab and insert 10,20,30,40,50,00 * * * * /opt/novell/groupwise/<script_name>.sh to run the script every 10 minutes
