How to Clean Up After a Failed 11g CRS Install in Linux
Not cleaning up a failed CRS install can cause problems like node reboots. Follow these steps to clean up a failed CRS install:
1. Run the rootdelete.sh script then the rootdeinstall.sh script from the
$ORA_CRS_HOME/install directory on any nodes you are removing CRS from. Running these scripts should be sufficent to clean up your CRS install. Rootdelete.sh accepts options like nosharedvar/sharedvar, and nosharedhome/sharedhome. Make yourself familiar with these options by reading the Oracle Clusterware and Oracle Real Application Clusters Administration and Deployment Guide. If for some reason you have to manually remove the install due to problems with the scripts, continue to step 2:
2. Stop the Nodeapps on all nodes:
srvctl stop nodeapps -n
3. Prevent CRS from starting when the node boots. To do this issue the following
as root:
rm /etc/oracle/*
rm -f /etc/init.d/init.cssd
rm -f /etc/init.d/init.crs
rm -f /etc/init.d/init.crsd
rm -f /etc/init.d/init.evmd
rm -f /etc/rc2.d/K96init.crs
rm -f /etc/rc2.d/S96init.crs
rm -f /etc/rc3.d/K96init.crs
rm -f /etc/rc3.d/S96init.crs
rm -f /etc/rc5.d/K96init.crs
rm -f /etc/rc5.d/S96init.crs
rm -Rf /etc/oracle/scls_scr
rm -f /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab
4. If they are not already down, kill off EVM, CRS, and CSS processes or reboot
the node:
ps -ef | grep crs
kill <crs pid>
ps -ef | grep evm
kill <evm pid>
ps -ef | grep css
kill <css pid>
Do not kill any OS processes, for example icssvr_daemon process !
5. If there is no other Oracle software running (like listeners, DB’s, etc…),
you can remove the files in /var/tmp/.oracle or /tmp/.oracle. Example:
rm -f /var/tmp/.oracle
or
rm -f /tmp/.oracle
6. Remove the ocr.loc
Usually the ocr.loc can be found at /etc/oracle
7. De-install the CRS home in the Oracle Universal Installer
8. Remove the CRS install location.
9. Clean out the OCR and Voting Files.
10. The /tmp/CVU* dir should be cleaned also to avoid the cluvfy misreporting.
11. It is good practice to reboot the node before starting the next install.
12.If you would like to re-install CRS, follow the steps in the RAC Installation manual.
