Note:
1. startOSWbb.sh has to be started in background by appending sign '&' at the end of the command line.
2. the output of startOSWbb.sh needs to be redirected to a file

Did not find helpful message, check OSWatcher log:

OSWatcher archive directory does not exist, manually create it:

Re-start resource ora.OSWbb
$ crsctl start resource ora.OSWbb CRS-2672: Attempting to start 'ora.OSWbb' on 'host02' CRS-2676: Start of 'ora.OSWbb' on 'host02' succeeded
Resource ora.OSWbb started successfully, make sure OSWatcher is running:
$ ps -ef | grep OSWatcher grid 7405596 5046352 0 10:13:16 pts/6 0:00 grep OSWatcher grid 7078198 11469280 0 10:11:23 - 0:00 /bin/sh ./OSWatcherFM.sh 720 /u01/app/grid/local/logs/oswbb/archive grid 11469280 1 0 10:10:54 - 0:00 /bin/sh ./OSWatcher.sh 30 720 NONE /u01/app/grid/local/logs/oswbb/archive
Note: Keyword 'OSWatcher' is reserved by OSWatcher stopping script to determine if the utility is running. DO NOT using string 'OSWatcher' anywhere (directory name, file name, command name, etc).
Test resource ora.OSWbb stop function:
$ crsctl stop resource ora.OSWbb CRS-2673: Attempting to stop 'ora.OSWbb' on 'host02' CRS-2677: Stop of 'ora.OSWbb' on 'host02' succeeded $ ps -ef | grep OSWatcher oragrid 12058682 5046352 0 15:15:50 pts/6 0:00 grep OSWatcher
Test resource ora.OSWbb restart function (check & start functions):
$ ps -ef | grep OSWatcher oragrid 11010394 5046352 0 15:18:33 pts/6 0:00 grep OSWatcher $ crsctl start resource ora.OSWbb CRS-2672: Attempting to start 'ora.OSWbb' on 'host02' CRS-2676: Start of 'ora.OSWbb' on 'host02' succeeded $ ps -ef | grep OSWatcher oragrid 7864326 1 0 15:18:42 - 0:00 /bin/sh ./OSWatcher.sh 30 720 NONE /u01/app/grid/local/logs/oswbb/archive oragrid 8388952 7864326 0 15:19:10 - 0:00 /bin/sh ./OSWatcherFM.sh 720 /u01/app/grid/local/logs/oswbb/archive oragrid 11665602 5046352 0 15:19:53 pts/6 0:00 grep OSWatcher
OSWatcher is running, kill one of two running processes:
$ kill 8388952 $ $ ps -ef | grep OSWatcher oragrid 7405662 5046352 0 15:20:26 pts/6 0:00 grep OSWatcher oragrid 7864326 1 0 15:18:42 - 0:00 /bin/sh ./OSWatcher.sh 30 720 NONE /u01/app/grid/local/logs/oswbb/archive
Process OSWatcherFM.sh is killed. Now wait for 1 minute and see what happens:
$ ps -ef | grep OSWatcher oragrid 14614732 6816014 0 15:21:11 - 0:00 /bin/sh ./OSWatcherFM.sh 720 /u01/app/grid/local/logs/oswbb/archive oragrid 6816014 1 0 15:20:42 - 0:00 /bin/sh ./OSWatcher.sh 30 720 NONE /u01/app/grid/local/logs/oswbb/archive oragrid 10355082 5046352 0 15:22:23 pts/6 0:00 grep OSWatcher $
Wow! The processes are restarted.
