10/21/09 Know the impact of using the ENDJOBABN command

If you use the ENDJOBABN command to end an active job that just won’t go away after the ENDJOB is issued, you need to be aware of the longer term impact of using this command.

When you use ENDJOBABN, a marker is set in the system that causes the next IPL to be considered an "abnormal" IPL – that is – the system will behave as if it ended abnormally, instead of in a controlled fashion from a PWRDWNSYS. This means that the first IPL you do after an ENDJOBABN will take longer than a normal IPL.

This is important to remember, because if you only IPL monthly or even less frequently, you might be surprised by the impact of an ENDJOBABN issued weeks prior.
