RE: Abnormal system end

[Jim Langston <jlangston@xxxxxxxxxxxxxxxx>]

An ABEND (Abnormal System End) can be caused by number of
things, the number one reason being a loss of power.  Short power
outage, someone comes along and trips over the power cord, some-
one turns off the machine and back on, etc...

Any reason that would cause the AS/400 to IPL without a "normal"
PWRDWNSYS being issued first.  Now, the log states that PWRDWNABN
was issued, which makes me think it was probably a power outage.  You
have a UPS on your AS/400, right?  If the power fails past the time you
have stated for the system to come down, the system will do a PWRDWNABN.
I don't know why it doesnt' do a normal end, probably because it would
take too long to shut down before the power ran out on the batteries.

Subject: Abnormal system end

Hi all,
Would anyone have any explanation for the following ?
On friday evening I signed on to the console and brought our sytem down to
restricted condition to run our full backup procedure as normal. While
looking throught the history log today I found the following messages :

1. Unattended IPL in progress after abnormal system end
2. Previous ending was abnormal because ENDJOBABN used.

After further investigation I noticed the system had taken an extra 2h
20mins to IPL on Saturday morning after the backup procedure, due to the
abnormal end I assume.

I know I did not issue the ENDJOBABN command during any of the procedure (I
have checked the logs, splf's, etc. to confirm). Possibly it had been issued
earlier in the week on a runaway user job, if so does using the ENDJOBABN
command allways result in the above ?
Does the ENDJOBABN command have any affect on the QABNORMSW system value ?

thanks

Neil
