Rather going to GUI or achieving this executing bunch of Unix commands I will show you how to do this in 1 minute and possibly less than 1 minute 🙂
My VM Host is Linux and I have SYSDBA access to DB : 126.96.36.199 (minimal required for 12c)
Step 1 : Stop all running processes
Go to BITools location : /u00/app/Oracle_Home/user_projects/domains/bi/bitools/bin
Then ./stop.sh # this will stop all processes associated with BI
Step 2: DROP RCU Schema — Needs SYSDBA privilege or ask DBA
Select * from System.SCHEMA_VERSION_REGISTRY where MRC_NAME='<add DB PREFIX>’; — Check DB Prefix where RCU is installed
delete from System.SCHEMA_VERSION_REGISTRY where MRC_NAME='<add DB PREFIX>’;
Locate all RCU schemas and Perform DROP schema operation . Typically it is 9 RCU schemas. For my case its below:
Step 3: remove the app folder :
in my case : rm -rf /u00/app
You can achieve this above by writing a Unix script combining all steps and just press one button .
This steps applicable for Linux env but for Windows you might need to clear extra stuffs sitting inside Registry.
If you don’t have direct access to database then for Step 2) you can user deinstall utility to drop the repository automatically and let the scripts do that internally.
