In both the latest Virtualization Cookbooks (ibm.com/redbooks), and the SLES 10 SP2 "read-only" root paper (linuxvm.org/present), there is a writeup on how to use CMM1 (much of this section was written by Ray Mansell - thanks Ray!). Search for "Enabling Collaborative Memory Management". It discusses how to also enable the collaborative piece: VMRM on z/VM. I'm curious that Barton wrote on August 28th: > VMRM has taken so much storage away from servers that the > server or application dies. I would HIGHLY recommend against using it. But he wrote today: > CMM-1 has very positive results So does CMM-1 have positive results without the collaborative piece? Barton, could you point to some numbers showing CMM-1 with positive results without VMRM? Did you use a different z/VM collaborative piece? Thanks.
