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 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 

3. Prevent CRS from starting when the node boots.   To do this issue the following

as root:



find . |egrep "css|crs|evm|oracle"


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

rm -f /etc/oraInst.loc 

rm -rf /tmp/.oracle

rm -rf /var/tmp/.oracle 

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/oraInst.loc

rm -rf /var/opt/oracle/ocr.loc

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 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.
