- crs_stop <resource name > -f
- start the resource again using srvctl start , then monitor for the same behavior
- If the previous steps not release this status , we will need to check the following logs
* $ORA_CRS_HOME/log/<hostname>/crsd/crsd.log
* Please also check if you can find any core file under CRS home specially under $ORA_CRS_HOME/log/<hostname>/racg/racgmain
* $ORACLE_HOME/log/<hostname>/racg/*
* as root run ocrdump and upload the generated output
- Please also upload the result of the following command list :
$crs_stat
$crs_stat -p
$crs_stat -ls
$srvctl config nodeapps -n <nodename1> -a -g -s -l
$srvctl config nodeapps -n <nodename2> -a -g -s -l
$srvctl config database -d <db_name> -a
$srvctl config service -d <db_name> -a
$srvctl config asm -n <node name>
$ocrcheck
$crsctl query css votedisk
$crsctl query crs activeversion
$crsctl query crs softwareversion
$oifcfg getif
$oifcfg iflist
Solution:
As the CRS is 10.2.0.4 , so as we agree on phone that you will need to apply either 10.2.0.4 Bundle Patch #2 ( bug 7493592 ) or 10.2.0.4 CRS Bundle Patch #4 (bug 8436582) and the both will fix bug:6196746 ,as the bundle patches are cumulative
