-------------------DBA's and Support Analysts10g RAC: How to Clean Up After a Failed CRS Install
---------------------------------------------------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.  Running these scripts should be sufficent
to clean up your CRS install.  If you have any problems with these scripts 
please open a service request.  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 <node name>3. Prevent CRS from starting when the node boots.  To do this issue the following

If they are not already down, kill off EVM, CRS, and CSS processes or rebootthe node:ps -ef | grep crs	kill <crs pid>ps -ef | grep evmkill <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/.oracleorrm -f /tmp/.oracle6. Remove the ocr.loc Usually the ocr.loc can be found at /etc/oracle7. Remove the CRS install location:rm -Rf <CRS Install Location>/*8. De-install the CRS home in the Oracle Universal Installer9. Clean out the OCR and Voting Files with dd commands.  Example:dd if=/dev/zero of=/dev/rdsk/V1064_vote_01_20m.dbf bs=8192 count=2560dd if=/dev/zero of=/dev/rdsk/ocrV1064_100m.ora bs=8192 count=12800If you placed the OCR and voting disk on a shared filesystem, remove them.If you are removing the RDBMS installation, also clean out any ASM disks if they have already been used.10.If you would like to re-install CRS, follow the steps in the RAC Installation manual.
