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 e 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 of=/dev/rdsk/V1064_vote_01_20m.dbf bs=1M count=256
dd if=/dev/zero of=/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 Oracle Clusterware Installation manual.
