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 on any nodes you are removing CRS from. Running  --切記：在所有的rac節點上
these scripts should be sufficent to clean up your CRS install. Rootdelete.sh
accepts options like nosharedvar/sharedvar, and nosharedhome/sharedhome. Make
yourself familiar with these options by reading the Oracle Clusterware and
Oracle Real Application Clusters Administration and Deployment Guide.
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 /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
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,在/etc/inittab中清除與cr相關的記錄（一般是三行）,在所有的rac節點上

10,在所有的rac節點上以oracle使用者rm -rf /orainventory目錄

11. Clean out the OCR and Voting Files with dd commands. Example:
dd if=/dev/zero f=/dev/rdsk/V1064_vote_01_20m.dbf bs=1M count=256
dd if=/dev/zero f=/dev/rdsk/ocrV1064_100m.ora bs=1M count=256
See the Clusterware Installation Guide for sizing requirements...
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.
12. It is good practice to reboot the node before starting the next install.
13.If you would like to re-install CRS, follow the steps in the RAC Installation manual.
