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.
