De-installation of WebLogic 12.2

We are decommissioning one of our Linux server, that server contains WebLogic instance, so as part of decommission we decided to de- installation WebLogic instance.
Below are the steps that we have to follow to de install Weblogic.

Step1:- Stop Node manager and WebLogic services.

cd $MW/user_projects/domains/base_domain/bin 
[oracle@DBsGuru bin]$ ls -lrt
-rwxr-x--- 1 oracle dba    794 Sep 24 13:43 setStartupEnv.sh
-rwxr-x--- 1 oracle dba   7309 Sep 24 13:43 startWebLogic.sh
-rwxr-x--- 1 oracle dba   2156 Sep 24 13:43 stopWebLogic.sh
-rwxr-x--- 1 oracle dba  14685 Sep 24 13:43 setDomainEnv.sh

-rwxr-x--- 1 oracle dba   1134 Sep 24 13:43 startNodeManager.sh
-rwxr-x--- 1 oracle dba   1083 Sep 24 13:43 stopNodeManager.sh
-rw-r--r-- 1 oracle dba 424934 Oct  1 13:57 startWebLogic.log
-rw-r--r-- 1 oracle dba  13515 Oct  1 14:01 startNodeManager.log

sh stopNodeManager.sh

sh stopWebLogic.sh

Step2 :- Go to <MW_HOME>\oui\bin and execute de install.

./deinstall.sh

Step3:- After successful de-install of Weblogic, we delete manually Middleware home.

cd /u01/app/oracle
drwxr-xr-x 6 oracle dba 111 Oct  1 14:51 middleware
rm -rf middleware
