Hi Neil,
I have done everything you're suggesting and they
all conform to what I learn at Common's but I think the only thing missing
from my definitions is that my QBATCH subsystem is sharing *BASE pool with all
subsystem and *MACHINE tasks. What I'm going to do is define a pool for
QBATCH and allow it to have *BASE as second sharepool.
What do you think?

This looks fine.
If you run DSPSBSD on each of the subsystems,
and take option 2 for Pool Definitions, you will see how many pools are
defined for that subsystem, and whether it's defined as *BASE, *INTERACT,
*SPOOL, *SHRPOOLxx - or as a Private Pool (size defined).
Work with subsystems is showing you for example, that
subsystem QINTER has 2 pools defined to it. The first pool defined (1)
is the system pool 2 - which WRKSYSSTS shows you is the *BASE pool. The
second pool defined (2) is system pool 4, which WRKSYSSTS shows you is
*INTERACT.
System pool 1 is always
*MACHINE, and system pool 2 is always *BASE. From there it depends on
what order the subsystems that use other pools are started.
The subsystem monitor runs in the
1st pool defined to the subsystem (usually *BASE - system pool 2).
Other pools used in the subsystems are
determined by the Pool identifier on the routing entries for the subsystem
(DSPSBSD, #7, F9).
As a first step
I would carve out a separate pool for Batch jobs.
In WRKSHRPOOL assign a size and activity level for
*SHRPOOL1.
In subsystem QBATCH:
Pool Storage
Activity
ID
Size (K) Level
1
*BASE
2 *SHRPOOL1
For routing entries 300, 700 &
9999 (the 3 default entries) change all Pool identifiers to 2.
And maybe also change subsystem QPGMR
same as above for Pool Id's.
For
routing entries 10, 20, 700 & 9999 (the 4 default entries) change Pool
identifiers to 1, 2, 2, 1.
You may
want to try QPFRADJ sysval at '3' to see how the system handles it (note your
pool sizes and activity levels so if it makes a mess of things you can change
QPFRADJ back to '0' and put you pool sizes & activity levels back where
they were.
If you decide to try
QPFRADJ = '3', use WRKSHRPOOL, F11, to set reassonable min/max sizes - so for
example it won't take away all the memory from QINTER during lunchtime
(assuming anyone actually takes lunch and doesn't just grab a sandwich and
work at their desks these days !).
An
example:
-----Size %-----
-----Faults/Second-----
Pool
Priority Minimum Maximum Minimum
Thread Maximum
*MACHINE
1 22.50 55.00
10.00 .00 10.00
*BASE 2
4.50 80.00 10.00
2.00 100
*INTERACT 1 2.50
80.00 5.00 .50
200
*SPOOL
3 .50 15.00
5.00 1.00 100
*SHRPOOL1 2
.75 80.00 10.00 2.00
100
*SHRPOOL2
2 1.00 100
10.00 2.00 100
*SHRPOOL3 2
1.00 100 10.00 2.00
100
*SHRPOOL4
2 1.00 100
10.00 2.00 100
*SHRPOOL5 2
1.00 100 10.00 2.00
100
*SHRPOOL6
2 1.00 100
10.00 2.00 100
Would suggest changing paging option for the pools
(can't change *MACHINE) from *FIXED to *CALC for all pools, via WRKSYSSTS or
WRKSHRPOOL - again, try it - it may work for you, it may not.

Subject: PERFORMANCE TUNNING,
SUBSYSTEMS & SHAREPOOLS |
Guys,
I just came back
from Common 2000 at Baltimore, MD and I'm looking around and changing some of
my system's configurations as they relate to PERFORMANCE TUNNING. One of
my discovery on my system seems weird. Below you'll see the printouts
from my WRKSYSSTS & WRKSBS. I think my SUBSYSTEMS are not defined
properly, their references to SUBSYSTEMS POOLS doesn't appear OK to me.
Please advice on how to set this up
correctly.
Thank you,
Dare
