Dxdumpdb is failing to create the backup. There are no errors in teh trace or alarm logs, however the warn log contains:
20170309.024143.540 WARNING: Unable to unpack syntax 4
Entry has no attributes
20170309.024213.282 WARNING: Parser found nothing
The warnings occur during the dxdumpdb operation to a corrupted datastore.
1. Get the .zdb from another working server.
2. Stop the non-working DSA.
3. Rename the .zdb and remove the .tx file and the .dp files or copy them out to another folder all together.
And then run the dxdumpdb command.
