How to Clean Up After a Failed 10g or 11.1 Oracle Clusterware Installation

10g and 11.1 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 
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.
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=1M count=256
        dd if=/dev/zero of=/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.
10. The /tmp/CVU* dir should be cleaned also to avoid the cluvfy misreporting.
11. It is good practice to reboot the node before starting the next install.
12.If you would like to re-install CRS, follow the steps in the RAC Installation manual.
