Deinstall Oracle Database 12c with all PDBs

Deinstall Oracle Database 12c with all PDBs


Here, i am listing how to deinstall oracle database 12c and all PDBs which are connected to the same CDB.



Step 1: Export ORACLE_HOME & PATH

bash-4.1$ export ORACLE_HOME=/mnt/Oracle/product/12.1.0.2/db_1
bash-4.1$ export PATH=$ORACLE_HOME/bin:$PATH
bash-4.1$ cd $ORACLE_HOME
bash-4.1$ cd bin


Go to the deinstall directory.

bash-4.1$ pwd
/mnt/Oracle/product/12.1.0.2/db_1/deinstall


Step 2: Run deinstall.sh, Below is the full listing of how deinstall process run through.
I have highlighted few parts in bold which needs user input and require more attention during deinstall process.


bash-4.1$ pwd
/mnt/Oracle/product/12.1.0.2/db_1/deinstall

bash-4.1$ ./deinstall

So, deinstallation completed and all files and folders also deleted except below directories.
/mnt/devops_0/Oracle/db1212/product/12.1.0.2/db_1/deinstall
This is because we have initiated deinstall process from above location hence Oracle cannot delete above directories. We can delete Oracle directory manually once deinstall process completed.
