In a sysplex, there are shared resources used by the various sysplex-wide components (e.g. ISGLOCK structure, CFs, couple datasets, security DB) that, if held up by a particular member, can cause slowdowns across the sysplex (a/k/a sympathy sickness). You probably have to 'drill down' to see what XCF resource is involved in the delays reported by RMF. >-Can isglock structure be split over several cfs - rmf shows we have 4 cfs active - and can traffic be directed to a specific cf? >(I'm almost sure that the answer is NO but I might perfectly be wrong) No. ISGLOCK must reside on a single CF. Of course, you can set the preference list for ISGLOCK to be a particular subset of CFs and rebuild the structure to get it to the preferred CF. No outage is required.
