RE: Controlling Job Types -- MIDRANGE-L

Laine,

We run multiple apps, needed to be to control both interactive and batch for all apps.
We created an interactive (INTER_**) and a batch (BATCH_**) subsystem for each app.
We chose BATCH_** so when one does an WRKACTJOB, you'll see any batch jobs running on page 1.
An app can easily be controlled by ending their two subsystems.
We do not start qinter, qbatch is started, but only for system default jobs.
All interactive subsystems use the *INTERACT memory pool.
We use wild card workstation entries so interactive users start in the proper subsystem.
All batch subsystems use the *SHRPOOL1.
Performance adjuster keeps every tuned as need. Batch *SHRPOOL1 will have little memory if no batch jobs running.

Rob,

What you say about memory allocation is true; however I suspect it's not going to be much of an issue on this box since they have been working in a simpler environment for at least some time. Managing the performance related system values will eliminate 90% of the potential land mines.

Correct. If you change your controlling subsystem from QBASE to QCTL it will break it up as desired.
A controlling subsystem of QBASE is the default. This should probably be changed to QCTL for all installations running a 'traditional' application such as ERP and whatnot with the old setup of 5250 users and batch jobs.

If your lpar is different, like all Domino (like many of my lpars), or almost no 5250 use but all web use, then a different setup is recommended.
Frankly I leave my "all Domino" partitions at QBASE. I have some lpars where it may be days in between when a single user signs in using 5250.
Other lpars where it may be weeks before more than 2 do. These lpars use QBASE.
One lpar where DSPSYSSTS shows 470 signed on users. That one (and a few
others) uses QCTL.

One caveat about breaking the subsystem out is memory tuning. Yes, there is an auto performance adjuster built into the system that if you leave running will shift memory around to the right pool. However, if the whistle blows at 5pm and 90+% of your users sign off of all their 5250 applications and a large quantity of intensive batch jobs kicks off then it may take awhile to properly shift memory from interactive to batch. And only slowly change it back when the starting bell sounds the next morning.
There are products to shift this faster. Some people have job schedule entries like DAY or NIGHT which shift that memory around in one big chunk at these times also.

Hello,

I'm running v6.1 and have some questions on how to control what subsystem Batch and Interactive jobs are processed.
What I'm trying to accomplish is to control access to the system for all application type users by stopping their subsystem(QINTER).

We currently have QCTLSBSD set at QBASE which is the shipped default.

From what I have read all job types are run under this subsystem. This

appears to be true for our current work load.
The application users profiles have Job Description of RMS61 with Library of QGPL.
Now if I changed QCTLSBSD to QCTL it will start the below subsystems...

QINTER ==== Interactive Started with QCTL
QBATCH ==== Batch Started with QCTL
QSPL ==== Spooling Started with either QBASE or QCTL
QCMN ==== Communication Started with QCTL
QSERVER === File Server Started with either QBASE or QCTL

So will my Interactive users now run under QINTER and the Batch jobs run under QBATCH without changes the Job Description?

Thanks,
Rogers
