10g RAC: How to Clean Up After a Failed CRS Install

1. Run the rootdelete.sh script with root. then the rootdeinstall.sh script. from the

$ORA_CRS_HOME/install directory. Running these scripts should be sufficent

to clean up your CRS install. 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

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

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

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

rm -rf /etc/oracle/

7. De-install the CRS home in the Oracle Universal Installer

./runInstaller

8. Remove the CRS install location:

rm -Rf /*

9. Clean out the OCR and Voting Files with dd commands. Example:

dd if=/dev/zero of=/dev/raw/raw1 bs=8192 count=128000

dd if=/dev/zero of=/dev/raw/raw2 bs=8192 count=128000

说明：dd命令为清空lv的文件头，其中of=后面为要清空内容的lv， bs=8192代表8k

count＝lv size (k)/ 8

如：orc 的lv的大小如果为128m, 则当bs＝8192时，

128m=131072k, count=131072k / 8k = 16384

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.If you would like to re-install CRS, follow the steps in the RAC Installation manual.
