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

---------------------------------------------------

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.  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:

注：步骤一的两个脚本如果能正常运行，就相当于执行了步骤2－4，再接着执行第

5步骤，如果无法正常运行以上两个脚本，则执行以下步骤

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

注：每个操作系统脚本的存放路径是不一样的

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 -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 或者执行：ps -ef | grep d.bin来检查服务是否还在运行

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:

rm -Rf /*

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

dd if=/dev/zero f=/dev/rdsk/V1064_vote_01_20m.dbf bs=8192 count=2560

dd if=/dev/zero f=/dev/rdsk/ocrV1064_100m.ora bs=8192 count=12800

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.
