4 Deregistering a Metadata Repository

If you need to deregister a metadata repository with Oracle Internet Directory, or if Oracle Application Server Repository Creation Assistant failed to register the metadata repository with Oracle Internet Directory, use the procedure described in this chapter to clean up the entries in Oracle Internet Directory.

You have to clean up the entries in Oracle Internet Directory before trying to register the metadata repository again.
