Getting Librarian 101 UPDATE FAILURE: IOU098E ENQUEUE OF MASTER FILE INDEX FAILED. Is there a way to resolve it?
The message IOU098E ENQUEUE OF MASTER FILE INDEX FAILED means that the master file is held by another job or task. Could be a –scan or librscan job is running. You can issue a TSO WHOHAS command and this should indicate the userid so you can determine what has enqueue the master file.
