10g and 11.1 RAC: How to Clean Up After aFailed CRS Install
------------------------------------------------------------
Not cleaning up a failed CRS install cancause problems like node reboots.
Follow these steps to clean up a failed CRSinstall:
1. 使用脚本卸载
Run the rootdelete.shscript then the rootdeinstall.sh script from the$ORA_CRS_HOME/install directory on any nodes you are removing CRS from.
Runningthese scripts should be sufficent to clean up your CRS install. Rootdelete.sh accepts options likenosharedvar/sharedvar, and nosharedhome/sharedhome.Make yourself familiar with these options by reading the Oracle Clusterware andOracle Real Application Clusters Administration and Deployment Guide. If youhave any problems with these scripts please open a service request.
If for some reason you have to manuallyremove the install due to problems with the scripts, continue to step 2:
2. 手工卸载 Stop the Nodeapps on all nodes:
srvctlstop 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
HPTru64:
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
IBMAIX:
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 CSSprocesses 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 other Oracle software running (likelisteners, 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.locUsually the ocr.loc can be found at /etc/oracle
7. De-install the CRS home in the Oracle UniversalInstaller
8. Remove the CRS install location.
9. Clean out the OCR and Voting Files with ddcommands. Example:
dd if=/dev/zero of=/dev/rdsk/V1064_vote_01_20m.dbfbs=1M count=256
dd if=/dev/zeroof=/dev/rdsk/ocrV1064_100m.ora bs=1M count=256
