When service is installed, the original versions of replaced files
are saved to allow the updates to be removed if necessary. To restore the
previous service level, issue an RPM uninstall for all the packages that were
updated by the maintenance package as follows:
- Log in as root.
- To find out which packages are installed on your machine, enter
the following:
rpm -q -a | grep MQSeries
Using the example given in Applying service,
returns: MQSeriesRuntime-6.0.0-0
MQSeriesSDK-6.0.0-0
MQSeriesServer-6.0.0-0
MQSeriesRuntime-Uxxxx-6.0.0-1
MQSeriesSDK-Uxxxx-6.0.0-1
MQSeriesServer-Uxxxx-6.0.0-1
- Remove all the updates applied at level 1, with the following commands:
rpm -ev MQSeriesRuntime-Uxxxx-6.0.0-1 MQSeriesSDK-Uxxxx-6.0.0-1
MQSeriesServer-Uxxxx-6.0.0-1
- Repeat step 2 to check that the packages have been returned to
their original levels:
MQSeriesRuntime-6.0.0-0
MQSeriesSDK-6.0.0-0
MQSeriesServer-6.0.0-0
