SCOPE & APPLICATION ------------------- DBA's and Support Analysts 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 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 /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. Clean out the OCR and Voting Files with dd commands.  Example:         dd if=/dev/zero f=/dev/rdsk/V1064_vote_01_20m.dbf bs=8192 count=2560         dd if=/dev/zero f=/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.
