You delete a database backend by using the dsconfig delete-backend command.
When you delete a database backend by using the dsconfig delete-backend command, OpenDJ does not actually remove the database files for two reasons. First, a mistake could potentially cause lots of data to be lost. Second, deleting a large database backend could cause severe service degradation due to a sudden increase in I/O load.
Instead, after you run the dsconfig delete-backend command you must also manually remove the database backend files.
If you do run the dsconfig delete-backend command by mistake and have not yet deleted the actual files, then you can recover from the mistake by creating the backend again, reconfiguring the indexes that were removed, and rebuilding the indexes as described in the section on Configuring & Rebuilding Indexes.
