I've received issue with XDB - in dba_registry it's displayed like invalid.
I used catqm.sql to reinstall it, but no success.
How is this issue solved?
If additional info must be provided, please tell me.
You might find some useful information in the XML DB FAQ
Did you run th efollowinf after catqm.sql?
Check XDB reloading in Note
