Re: Idcams Listdata and ESS
Thanks all. Indeed weird software/programmer behaviour. At least we have Astex, that does know what is inside an ESS. Kees. [EMAIL PROTECTED] wrote in message news:[EMAIL PROTECTED]...

Idcams Listdata and ESS
Hello all, I have a problem with IDCAMS LISTDATA that I can't believe to happen, but can't find a fix: IDCAMS LISTDATA STATUS consistently reports for all SSIDs on all ESS's half of the real cache size and half of the real NVS size. This should have been apar-ed and fixed by now, or am I the only user of LISTDATA in this century? Where is the problem?

Re: Idcams Listdata and ESS
To have a quick answer : The ESS is build of two clusters - each responsible for half of the Subsystem. Therefore it reports only half of the total values . I know it is described - but actually not where . Will post it when i find it. So no bug - no apar Frank Krueger Donnerstag, 9.

Re: Idcams Listdata and ESS
Found it - ESS cache and NVS reporting RMF cache reporting and the results of a LISTDATA STATUS command report a cache size of 4,8, 12, 16, 32 GB and an NVS size of 1 GB half the actual size. This is because the information returned represents only the cluster to which the logical control unit is attached. Chapter 5.11 Performance - z/OS environment tools.
