Hello all,
I am looking at the TSM 5.1 Quick Start book for Os/390 + z/OS. In
chapter 2 there is a section 'REGION SIZE FOR YOUR TIVOLI STORAGE MANAGER
SERVER. The section goes through a process for determining the best region
size to assign to TSM. The last sentence says, 'Specifying 0M will result
in poor server performance.' WHY?
I am dealing with a long outstanding, not solved problem. I have my
region size up at 1000M. (I am using a 9672-x57 that has about 7GB of
memory on the lparand a TSM server with a 25GB DB and 230 clients). The
problem is TSM will 1 or 2 times a week start using all of 1 processor to
do some simple work, like run 5 migration processes. I will take TSM down
and up. It then continues on getting work done faster and using 1/4 of one
processor. Does TSM do something with memory assignments internally that
too large of a REGION causes a problem?
