10g and 11.1 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 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 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

3. Prevent CRS from starting when the node boots. To do this issue the following as root: Sun: rm /etc/init.d/init.cssd rm /etc/init.d/init.crs rm /etc/init.d/init.crsd rm /etc/init.d/init.evmd rm /etc/rc3.d/K96init.crs rm /etc/rc3.d/S96init.crs rm -Rf /var/opt/oracle/scls_scr rm -Rf /var/opt/oracle/oprocd rm /etc/inittab.crs cp /etc/inittab.orig /etc/inittab Linux: 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 HP-UX: rm /sbin/init.d/init.cssd rm /sbin/init.d/init.crs rm /sbin/init.d/init.crsd rm /sbin/init.d/init.evmd rm /sbin/rc2.d/K960init.crs rm /sbin/rc2.d/K001init.crs rm /sbin/rc3.d/K960init.crs rm /sbin/rc3.d/S960init.crs rm -Rf /var/opt/oracle/scls_scr rm -Rf /var/opt/oracle/oprocd rm /etc/inittab.crs cp /etc/inittab.orig /etc/inittab HP Tru64: rm /sbin/init.d/init.cssd rm /sbin/init.d/init.crs rm /sbin/init.d/init.crsd rm /sbin/init.d/init.evmd rm /sbin/rc3.d/K96init.crs rm /sbin/rc3.d/S96init.crs rm -Rf /var/opt/oracle/scls_scr rm -Rf /var/opt/oracle/oprocd rm /etc/inittab.crs cp /etc/inittab.orig /etc/inittab IBM AIX: rm /etc/init.cssd rm /etc/init.crs rm /etc/init.crsd rm /etc/init.evmd rm /etc/rc.d/rc2.d/K96init.crs rm /etc/rc.d/rc2.d/S96init.crs rm -Rf /etc/oracle/scls_scr rm -Rf /etc/oracle/oprocd rm /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 ps -ef | grep evm kill ps -ef | grep css kill 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 with dd commands. Example:

dd if=/dev/zero f=/dev/rdsk/V1064_vote_01_20m.dbf bs=1M count=256
dd if=/dev/zero f=/dev/rdsk/ocrV1064_100m.ora bs=1M count=256

See the Clusterware Installation Guide for sizing requirements...

If 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. 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.
