The QDBJRN Journal

Troubleshooting


Problem

This document provides an explanation of the QDBJRN journal in library QRECOVERY.

Resolving The Problem

The QDBJRN journal is a journal in library QRECOVERY that is used to journal the system cross-reference files in QSYS. It is desirable for these cross-reference files to be journaled to allow recovery of the files following an abnormal system end rather than rebuilding the entire files. Journaling might not be ended for these files.

The attached receivers for the QDBJRN journal are set up to be managed and deleted automatically by the system. No user maintenance by the user is required. The threshold of the journal receiver is set at a fairly low value to minimize the amount of journal receiver space used by this journal at any time. Because this value is set quite low, users might periodically receive messages at the system operator message queue indicating that the current journal receiver for QDBJRN has been detached and a new receiver has been attached. These are normal messages, and they can be ignored.

If the user notices that these detachment messages are occurring frequently, it is probably an indication that some significant system maintenance is being performed on the system cross-reference files. Examples of system maintenance that could create this condition include:

oDeleting a library containing numerous data files
oRestoring a library containing numerous data files
oDuplicating a library containing numerous data files
oSystem cross-reference files rebuilding due to damage found on the files
oInitial installation of a new operating system release
The journal detachment messages are considered normal, regardless of their frequency, and should be ignored.
