Manually Drop Dbconsole Repository in 11g

OEM - STEPS TO MANUALLY DROP DBCONSOLE REPOSITORY IN 11g

MANUALLY DROP DBCONSOLE REPOSITORY In 10g when you use EMCA utility to drop/recreate the repository, Oracle puts the database in a quiesced state. I.e. All user access will be temporarily halted. But starting from 11.2.X, you can safely ignore the Warning; because Oracle never puts the database in quiesce state. Let’s start manually to drop Database Console and its repository in 11g.
