Re: processing speed

Pool 1 is always *MACHINE pool.
It is not obvious which pool on your list is the one from QBATCH subsystem.
Looking at your command I would suspect you use private pools in your
susbsystems configuration.
I would suggest to change all your susbsystems to use shared pools - *BATCH,
*INTERACT, *SPL  and *SHRPOOL1-n.
Also change system value QPFRADJ to value 2 or 3.
In this way you will let performance adjuster to chage pool sizes depending on
the workload.
Then if you have single job running, it will gradually pull in most of memory in
its pool.

Subject:  processing speed





 I want to run a group of programs using all the resources that I can safely
use. No one else will be on the system at that time. The following is our
current memory pool size. Can I use CHGSBSD to alter the storage size of the
pool for faster processing? If so, what size?

Sys      Pool   R
Pool    Size K
  1      53272
  2      29452
  3       2620
  4     154800
  5       2000
  6      20000

We have a job that alters the memory with the following:

  CHGSBSD    SBSD(QBATCH) POOLS((1 15000 1)) MAXJOBS(1)

Will the 15000 in the CHGSBSD command be reflected as 15000 as the pool size
for pool 1 on the WRKSYSSTS?  It looks like they're both in kilobytes to me.
The reason I question this is that this would reduce the memory size for the
pool and I know that the reason it was done to this particular job was to
increase it so that it would run faster. TIA for your help.
