Our DBA has been looking at increasing several of the buffer pools. I know he
said that buffer/cache hits was in the 60% range on Monday. He did 2 rounds of
tuning, including bouncing the DB2 region last night. DB2 is shut down usually
only on the weekend with our weekly IPL.
The problem we
be a doable
target.

DB/2 lives in Buffer pool city. The first bottle neck is
underallocated pools. Lots of tuning opportunities. Craig Mullin's(formerly

Hopefully you get what storage you need contiguous or it's not just an IPL
anymore..I got bit by this just last week.

Standard plea to customers: Find out how much memory you actually have on
each machine and ensure you deploy the right portions of that as reserved
to the right LPARs. (This is not the only situation this quarter where a
customer was forced to IPL to add memory out of idle to an LPAR.)
And stan
I just talked to our DBA, and yes, we did REBIND all of our packages. I
suspect we are now just over the knee of the curve - but the curve for what?

Thanks to all that replied. I'll only reply to this answer to avoid cluttering
up the list. I suspected that I probably couldn't add any storage to this Lpar
without at least an IPL. Both of LP01 and LP02 have 2 GB defined for real
storage, and 1GB in reserve. I believe the 1GB in reserve g
Looks the memory issue was already covered. For DB2 V8 did you REBIND all of
your packages???

Can real storage be added to an Lpar on a z/800 without shutting down the Lpar
and re-IPLing? We have 4 Lpars defined, only two of them running now. Both
Lpars have 3G of memory. I think the 2 Lpars that aren't running have .5G
each. I know we have a little less than 1G that is free and unas
