Real Application Cluster database upgradtion from 10.2.0.1 to 10.2.0.4

Real Application Cluster database upgradtion from 10.2.0.1 to 10.2.0.4



Database Version: 10.2.0.1

Operating System: Ret Hat linux 4 As & Vmware 5

Storage Type : ASM & RAW Storage


Pre-Request for upgrade:


Before upgrading any database we need take complete cold backup for database. Also we need to take backup of ORACLE_HOME, ORACLE_BASE & ORACLE_CRS_HOME


  • In my case I taken ORACLE_HOME & ORACLE_CRS_HOME backup’s using (for all nodes)

cd /u01/before_patch_backup

tar -cvf oracle_base_jul19.tar $ORACLE_BASE

tar -cvf oracle_home_jul19.tar $ORACLE_HOME

tar -cvf oracle_crs_home_jul19.tar $ORACLE_CRS_HOME


  • Form storage level we need take backup’s. I used “dd” command for taking OCR & VOTING disk backups.


  • Also using I have taken complete RMAN backup for my database & using “dd” command I taken RAW devices backups (I mean ASM)


PS: Make sure; before taking any backups you need to sotp your cluster don’t forgot. Using the below command you down your cluster.


[root@linux1 bin]# ./crsctl stop crs

[oracle@linux2 /]$

[oracle@linux2 /]$ ps -ef | grep lsn

oracle 20638 19349 0 05:54 pts/1 00:00:00 grep lsn


PS: In my test environment I don’t have separte ASM home; I’m using ORACLE_HOME itslef. If you have ASM home then you may need take backup of ASM home also.


Cluster Upgration:



Now I’m going to upgrade my cluster database. Please carefully gothrow below screen shots & SQL Scripts.


Step1:



  1. Down 10.2.0.4 patch set (Patch Nr: 6810189)
  2. Extract your patch
  3. From oracle user you need to exeucte “runInstaller” then you will get below screen shot.




Step2:



Please confirm your CRS Home. Because first of all you need to upgrade cluster only (Not Oracle database or ASM Home)





Step3:



This is TWO Nodes cluster; that’s why you will get your cluster nodes names list.






Step4:



This is pre-request checking steps; in case any thing wrong here you will come to know all the details.




Step5:



Once successfully completed your pre-request then continue the patch installation on cluster.





Step6



After succesfully installation you may need execute the below script from root user (in all nodes you need follow same steps)



/u01/app/oracle/product/10.2.0/crs/bin/crsctl stop crs


/u01/app/oracle/product/10.2.0/crs/install/root102.sh




Form Node1

I am having some problem in Node2 that’s why GSD down in node2.
