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:
 
2. Stop the Nodeapps on all nodes:
 
        srvctl stop nodeapps -n <node name>
 
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/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 <crs pid>
        ps -ef | grep evm
        kill <evm pid>
        ps -ef | grep css       
        kill <css pid>
 
   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 -rf /var/tmp/.oracle
 
        or
 
        rm -rf /tmp/.oracle
 
6. Remove the ocr.loc 
   Usually the ocr.loc can be found at /etc/oracle
 
7. Remove the CRS install location:
 
        rm -Rf <CRS Install Location>/*
 
8. De-install the CRS home in the Oracle Universal Installer
 
9. Clean out the OCR and Voting Files with dd commands.  
    * if /dev/rdsk does not exist, you can skip this
   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.
