清除Oracle 10g RAC CRS的方法

由于前面安装clusterware出现问题,因此重新安装,但是每次执行root.sh的时候,总有

Failure at final check of Oracle CRS stack.
10.

开始查询问题.应该是前面安装的crs没有删除干净.下面是一个帖子,说明如何干净的删除crs.

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 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
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

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 of=/dev/rdsk/V1064_vote_01_20m.dbf bs=8192 count=2560
       dd if=/dev/zero of=/dev/rdsk/ocrV1064_100m.ora bs=8192 count=12800

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.
