Deinstall Oracle 19c Binaries along with Databases


In this article, we are going to demonstrate Deinstall Oracle 19c Binaries along with Databases on the operating system Linux. Deinstall is required if a server is going to decommission or binary is no more required specific to a version. Before moving to practical below are a few points to remember.

1. Make sure to invoke deinstall tool from the same ORACLE HOME which you want to deinstall.

2. It will remove all services running from the same ORACLE HOME if any along with removing all physical files, FRA, DIAG, SPFILE associated with running databases of HOME, ORACLE HOME directory, oraInventory (only If no other registered HOME/s to central inventory), checkpoints, etc.

3. Optionally you may take backup of databases and ORACLE HOME.

4. Deinstall command-line utility available in $ORACLE_HOME/deinstall/.

Let’s move to execute deinstall utility to remove Oracle 19c binary along with running two databases and LISTENER services associated with the home.

1. Set environment variables: 

[oracle@DBsGurun5 ~]$ . oraenv
ORACLE_SID = [oracle] ? labcdb08
The Oracle base has been set to /u01/app/oracle


2. Launch tool deinstall:

[oracle@DBsGurun5 ~]$ cd $ORACLE_HOME/deinstall/
[oracle@DBsGurun5 deinstall]$ ls -lrt deinstall
-rwxr-x---. 1 oracle oinstall 11239 Oct 26 12:50 deinstall

[oracle@DBsGurun5 deinstall]$ ./deinstall
Checking for required files and bootstrapping ...
