How to deinstall Oracle 10g database software

In oracle 10g, you need to use the oui (oracle universal installer) script supplied in the $ORACLE_HOME/oui/bin folder, as shown below.


# Log in as the oracle 10g user, and set the environment to the ORACLE_HOME you are about remove.
# Check the current ORACLE_HOME
echo $ORACLE_HOME
/u01/oracle/product/10.2.0.4/db

# run oui in silent mode, and point to the correct Oracle 10g home:

cd /u01/oracle/product/10.2.0.4/db/oui/bin
./runInstaller -deinstall -silent REMOVE_HOMES={"/u01/oracle/product/10.2.0.4/db"}

Expected output:
