The sample REVUXLOG does not cater for LOCAL mode

Currently, the REVUXLOG sample source passes the DDNAME to the exit for use. This is fine for HUB mode but for LOCAL mode the DDNAME can be the same across multiple databases thus requiring a different method (such as JFCB processing) to determine what database it is that is switching logs. It would be useful to additionally supply the actual DBID to the exit (irrespective of the report e.g. ALL).

Alternatively, passing the DSN if feasible or modifying the exit to include JFCB processing (or some such method) to attain the DSN would also work.
