Re: Last IPL date and time

[Al Mac <macwheel99@xxxxxxxxxxx>]

Thanks for the stimulating question that got me looking some places I ought 
to be more familiar with.

DSPMSG QSYSOPR
F18 to get to the oldest entries

When we have an IPL, the System Operator Message Queue is erased and restarted.

Message Queues get all kinds of stuff from OS/400, from various application 
programs, and from end users human MSG*ALL which can clutter collection to 
point that perhaps you only want to view a sub-set based on nature of 
message severity etc.

Contents of message queues can disappear if
* Human opts to delete a message or collection of messages
* GO CLEANUP is set to wipe some out after so many days
* The Queue fills up and wraps

Joblogs are generated for all sorts of things, we habitually delete ours 
after backups, saving only those related to some reported problem.  If you 
have not been deleting your joblogs, check on those owned by master 
security officer QSECOFR ... the first one is probably related to the last 
re-IPL.

All our connection disconnection hassles (T1 phone line, printer messages 
etc.) end up in QCFGMSGQ ... yours might go some place else depending on 
your WRKSYSVAL

You might display all your message queues, etc. to see what others are 
populated with useful data DSPMSG* and WRKMSG* and GO CMDMSG
ignore those associated with users and their work stations, except those 
starting with letter Q are ones to review
ignore those in the libraries of application software

Most of the places you want to view are in
WRKMSGQ Q* Q*
(Q* message queues in Q* libraries), except this command not accept the 
second positional limitation

Remember there may be relevant queues not in your library list

Our QCONSOLE has message last time GO POWER was activated
Our QPGMR has traffic from stuff being reactivated in re-IPLs
Our QTCP has traffic from recovery from communication disruptions, 
including last re-IPL

Remember if option to do a "5" you can get time stamp when stuff happened, 
and if "5" not available to you, get same info via cursor on the message 
then F1
