DBA_REPCATLOG
The DBA_REPCATLOG view at each master site contains the interim status of any asynchronous administrative requests and any error messages generated. All messages encountered while executing a request are eventually transferred to the DBA_REPCATLOG view at the master site that originated the request. If an administrative request completes without error, then ultimately all traces of this request are removed from the DBA_REPCATLOG view. Its columns are the same as those in ALL_REPCATLOG.
