is if anyone has
done any research on an advantage to NOT USING SELFTUNBUFPOOLSIZE. Right
now I set BUFPOOLSIZE to 32760 and SELFTUNEBUFPOOLSIZE yes. From the looks
of things TSM seems to be able to cause some thrashing with MVS memory
management. SO I wonder if SELFTUNEBUFPOOLSIZE should be set
.

Hello all,
I have been
:Re: OS390 SELFTUNEBUFPOOLSIZE yes/no?
I like to set it about 10% higher than the happy point and set it to yes on
AIX. Then check it every once and a while to see if it needs adjusting.
The problem is you can create a lot of GETMAINs on MVS if you do not set it
high enough to begin

Paul,
How can I tell what size my BUFPOOLSIZE has grown to? I know I
start at 32MB but I don't know how much it grows/shrinks.

Matt,
I have always had SELFTUNEBUFPOOLSIZE no
By the way I run with buffpool 48mb against
28 gb database 70% full.
Experiment with some different settings against same workloads
to see which gives you best results.
cheers,
John

If you do a q status command, look at the line titled BufPoolSize. This
is the actual bufferpoolsize that has being used when using
SELFTUNEBUFPOOLSIZE set to YES..

You can check the size of your buffer pool by querying your server
options.

Hi TSM-ers,
I have set SELFTUNEBUFFPOOLSIZE to YES and the
BUFPoolsize in DSMSERV.OPT to 131072.
When EXPIRE INVENTURY has finished I get message
ANR0386I The BUFPoolsize has been changed to 131072
Is this pure coincidence or does this message tell me that
SELFTUNEBUFFPOOLSIZE doesn't work?
