Recreating the Database Control Repository

I don’t know why, but after I upgraded my database to 10.2.0.2, the DB Console started to behave quite unusual. For example, I was not able to submit backup jobs because it was complaining that the host privileges were not set up. Trying to manually set those privileges within the “Preferences/Host Preferred Credentials” was unsuccessful because the displayed page was simply empty. So, I decided to recreate the repository and this fixed my problem. Below are the steps I followed:

1. drop the repository:



 emca -deconfig dbcontrol db -repos drop



2. recreate the repository using dbca.
