Barbara, here's my point... You can think of XCF as a queuing mechanism between members on (potentially) different systems in the plex...
The mechanism has various queuing areas (whether it be "buffer pools" in memory owned by XCF or coupling facility list structures). Conventional wisdom has it that one configures the buffer pools large enough and one doesn't worry too much about the size of the coupling facility structures - in that you use CFSizer to size them and don't bother tuning from there. I'm wondering whether one wouldn't be better off making the structures bigger and (perhaps) the buffer pools in the z/OS systems smaller. In other words, what are the trade offs for biasing towards space in the CF list structures vs biasing towards space in XCF buffers in z/OS? I'm not sure that makes it any clearer. :-) Martin Martin Packer Performance Consultant IBM United Kingdom Ltd +44-20-8832-5167 +44-7802-245-584 [EMAIL PROTECTED] Unless stated otherwise above: IBM United Kingdom Limited - Registered in England and Wales with number 741598.
