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.

02/23/09 Learn more about any IPL process

Want to know more about an IPL than simply the date and time of the last IPL? Sometimes, the information provided by system values is just not sufficient. For instance,

- Did your last IPL take longer than usual?
- Did you recently apply PTFs and wanted to know how long that IPL step took?
- Need to know how long your system spent doing journal recovery?
- Need to know how long it actually takes to "power down"?

By making a simple program call, you can get a spool file that shows your last
power-down and IPL in full detail - Every system reference code and sub-code
is shown, along with the date and timestamp it was issued.

CALL QWCCRTEC

This program runs very quickly, and does not issue any messages. It produces
a QPSRVDMP spool file of about 15-20 pages. Look beyond column 85 for the
information you need. Here's a sample :
