UnInstalling/Deinstalling RAC Software 11gR2 and later

Uninstalling RAC software is very simple using deinstall utility. Deinstall utility is available in each oracle home installed in server. In RAC 11gR2, we have two ORACLE_HOMEs. First un-install rdbms database home and then un-install grid oracle home. I am presenting you the session log which i used to un-install a RAC 3-node cluster 11.2.0.3 to help you with the prompts while using the deinstall utility.

1. Deinstall rac database :
[oracle@askmlabsrac1 ~]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/deinstall/
[oracle@askmlabsrac1 deinstall]$ ./deinstall

[oracle@askmlabsrac1 ~]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/deinstall/
[oracle@askmlabsrac1 deinstall]$ ./deinstall
Checking for required files and bootstrapping ...
