Procedure

Preparation

Ensure that there are no databases using this Oracle Home.

Run Deinstall Command

Following the example given in Example of Running the Deinstall Command, I ran the following commands as the oracle user to deinstall the Oracle RDBMS home:

cd /opt/app/oracle/product/12.1.0/dbhome_1/deinstall ./deinstall

The output log is attached as deinstall.log.

Clean Up Remaining Directories

Although the deinstall log says that files were in use, these files were owned by root. Ran the following command to remove these files and associated directories:

sudo rm -fR /opt/app/oracle/product/12.1.0/dbhome_1
