Appendix B. Applying Maintenance to MQSeries for AS/400
This appendix tells you how to apply maintenance to MQSeries for AS/400.
Service updates for MQSeries for AS/400 are supplied as PTFs (Program
Temporary Fixes). They may be supplied on a CD-ROM, or you may obtain
them electronically as save files, which are normally stored in the QGPL
library. For details of how to load and apply PTFs and read their cover letters,
see the AS/400 Basic System Operation, Administration, and Problem Handling
manual, SC41-5206.
Before loading and applying a PTF:
v Read the cover letter carefully to see if you need to take any special actions.
v Quiesce all queue managers, as described in “Quiescing V5.1 of MQSeries
for AS/400” on page 24.
Reinstalling MQSeries for AS/400
You can reinstall MQSeries for AS/400, V5.1 without losing any of your data.
When you reinstall MQSeries for AS/400, the system checks whether the
MQSeries configuration file (mqs.ini) exists. If the file exists, it is kept and
used with the newly installed system. If the file does not exist, an empty
mqs.ini file is placed in the directory /QIBM/UserData/mqm.
All data that you have in the UserData directory is transferred to the newly
installed system. In addition, all the queue manager-associated libraries
containing journal and receiver information are transferred to the new system.
