10g and 11.1 RAC: Howto Clean Up After a Failed CRS Install
------------------------------------------------------------
Not cleaning up afailed CRS install can cause problems like node reboots.Follow these steps toclean up a failed CRS install:
1. Run therootdelete.sh script then the rootdeinstall.sh script from the$ORA_CRS_HOME/install directory on any nodes you are removing CRS from.
Running these scriptsshould be sufficent to clean up your CRS install. Rootdelete.sh accepts options likenosharedvar/sharedvar, and nosharedhome/sharedhome.
Makeyourself familiarwith these options by reading the Oracle Clusterware and Oracle RealApplication Clusters Administration and Deployment Guide.If you have anyproblems with these scripts please open a service request.
If for some reason youhave to manually remove the install due to problemswith the scripts, continueto step 2:
2. Stop the Nodeapps onall nodes:
$ srvctl stop nodeapps-n
3. Prevent CRS fromstarting when the node boots. To do thisissue 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/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/rc2.d/K960init.crs

rm -Rf /var/opt/oracle/oprocd
rm /etc/inittab.crs
cp /etc/inittab.orig /etc/inittab

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 notalready 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 exampleicssvr_daemon process !
5. If there is no otherOracle software running (like listeners, DB's, etc...),
you can remove the files in /var/tmp/.oracleor /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 CRShome in the Oracle Universal Installer
8. Remove the CRSinstall location.
9. Clean out the OCRand Voting Files with dd commands. Example:
dd if=/dev/zeroof=/dev/rdsk/V1064_vote_01_20m.dbf bs=1M count=256
dd if=/dev/zeroof=/dev/rdsk/ocrV1064_100m.ora bs=1M count=256
See the ClusterwareInstallation Guide for sizing requirements...
If you placed the OCRand voting disk on a shared filesystem, remove them.
If you are removing theRDBMS installation, also clean out any ASM disks if they have already beenused.
10. The /tmp/CVU* dirshould be cleaned also to avoid the cluvfy misreporting.
11. It is good practiceto reboot the node before starting the next install.
12.If you would like tore-install CRS, follow the steps in the RAC Installation manual.
