VM/ESA Data in Memory Techniques

This presentation was most recently given at SHARE in Atlanta, August 1997.


I went to buy a hammer the other day. I could not believe all the choices: claw, rubber, ball-peen, sledge. The sales clerk said "If you think this is bad, you should try choosing a VM data-in-memory technique for performance.". This session will outline the weak points and strong points of various DIM techniques available on VM/ESA so that you can pick the right tool for the right job. Techniques included are: minidisk cache, CMS file cache, saved segments, virtual disk in storage, and VM data spaces.
