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

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.
