How to Clean Up After a Failed 10g or 11.1 Oracle CRS(Clusterware Installation)

1. Runing following scripts from any nodes should be sufficent to clean up your CRS install

_$CRS_HOME/install/rootdelete.s_h $CRS_HOME/install/rootdeinstall.sh

Rootdelete.sh accepts options like nosharedvar/sharedvar, and nosharedhome/sharedhome.

If for some reason you have to manually remove the install due to problemswith the scripts, continue to step 2:

1. Stop the Nodeapps on all nodes (e.x santaro,pandora )

srvctl stop nodeapps -n _santaro_srvctl stop nodeapps -n _pandora_

2. 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

1. If they are not already down, kill off EVM, CRS, and CSS processes or reboot the node:

ps -ef |grep crs ps -ef|grep evm ps -eaf|grep css

Do not kill any OS processes, for example icssvr_daemon process !

1. 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/*

1. Remove the ocr.loc ( Usually the ocr.loc can be found at /etc/oracle)
2. De-install the CRS home in the Oracle Universal Installer
3. Remove the CRS install location.

rm -rf /*

4. Clean out the OCR and Voting Files with dd commands

for i in 1 2

do dd if=/dev/zero of=/dev/ocrdisk$i bs=8192 count=25000 done

for i in 1 2 3 do dd if=/dev/zero of=/dev/votedisk$i bs=8192 count=25000 done

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.

1. The /tmp/CVU* dir should be cleaned also to avoid the cluvfy misreporting.

rm -rf /tmp/CVU*

2. reboot the node before starting the next install.
