Re: [EXTERNAL] Log everything for a user

One reason I've seen a few times is not specifying "no lock" when building a selection subfile in a maintenance program. Last record in the subfile stayed locked and other users entering the same program went kaboom.

In my experience, the most common causes of long-term locks are:

   1. Maintenance Screen holding a lock waiting for user response. (User
   down the pub quaffing ale)
   2. Some process has accessed a record for UPDATE but is only doing the
   UPDATE based on certain conditions and has not issued an UNLOCK in the
   situation where it's not updating.
   If this is the LAST record processed (i.e it doesn't go on to read
   another record (releasing the previous lock) then the lock remains until
   the program ends.

Is it possible that some kind of housekeeping over the weekend triggers
something like 2. above to kick in?

One option is to change the submitted job.  Have it check for a lock on

You know what.  I'm just going to change the SIGNOFF default to *LIST
before leaving work tomorrow..  Hardly any sign ons over the weekend, so

we

should not get too many unwanted joblogs.

Hi Jeff
The answer may not be what you want to hear We had the same problem -
and the only way to capture what/who was creating this lock was to
sign on myself on Sunday night We found the cause and made the
necessary change Alan Shore E-mail : ASHORE@xxxxxxxx Phone [O] : (631)

Subject: [EXTERNAL] Log everything for a user

I've got a user who, on Sundays nights only, gets a lock on a
particular file in his interactive job that does not get released.
Later in his shift it causes an issue for a job he submits that needs
exclusive access to that file.  I can't figure out where that lock is
coming from and not being released.  He doesn't do anything different
on Sunday than the rest of the week, yet this only happens on Sunday.

I want to capture the joblog from his interactive job.  I changed his
initial program to include a  LOG(4 00 *SECLVL) LOGCLPGM(*YES) on him
to capture what he's doing.

However, if he does a SIGNOFF *NOLIST I won't get the job log anyway.
He signs off via menu option, but it could be one of several menus.
So I either change the option on any menu he could sign off from, or I
change the default on the SIGNOFF command for this weekend.

Some other easy way I haven't thought of?

Thanks.
