Restoring the previous service level

 

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:

1. Log in as root.

2. 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

3. 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

4. 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

For further information on using RPM to install software packages, see your Linux documentation.
