Removing old Oracle Homes

in Database Install/Upgrade/Opatch (MOSC) 5 commentsAnswered

Which method is better for removing old Homes from RedHat 8.8?

Existing Homes per /u01/app/oraInventoryContentsXML/inventory.xml

19.14.0, 19.15.0, 19.18.0.

under /u01/app/oracle/product/19.X.0/dbhome_1.

There are 2 databases on this host running 19.18.0 home.

So we know 19.14.0 and 19.15.0 are not in use. Here we want to remove 19.14.0.


Method 1: use deinstall

export ORACLE_HOME=/u01/app/oracle/product/19.14.0/dbhome_1 (old home to be removed)

cat /etc/redhat-release

export CV_ASSUME_DISTID=OL8

echo $ORACLE_HOME (confirm that this is old home to be removed)

cd $ORACLE_HOME

$ORACLE_HOME/deinstall/deinstall


Method 2: deregister old home and then use rm -rf <Old Home>
