How to remove(deinstall) an Oracle home

How to remove(deinstall) an Oracle home


Note: we have to be very careful while removing oracle home. All the databases associated with it also get removed. So please verify it from extra pair of eyes.


1. Set the oracle home which you want to remove.

export ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_2

2. Go to the directory -/u01/app/oracle/product/11.2.0/dbhome_2/deinstall/

oracle@hsot1-/home/oracle/>cd /u01/app/oracle/product/11.2.0/dbhome_2/deinstall

3. Here you can see the deinstall executable:

oracle@host1-/u01/app/oracle/product/11.2.0/dbhome_2/deinstall/>ls -ltr
