Hello expert
we are analyzing the IPC / VMC setting for performance, we have 5G ram for VMC, just wonder if someone if recommend the values for
rdisp/min_jvm,
rdisp/max_jvm,
vmcj/option/percentageYoungGen (sap says 100M, but isn't it depend on how much memory we have for the JVM?),
vmcj/option/percentageMinOldGen,
vmcj/option/maxJavaHeap
We have IPC running in VMC, I am monitoring in st03 for the performance. My another question is: what is acceptable average VMC response (AvgVMC CPU) time? I've seen most of time it's around 100ms, but sometime it goes up to 700ms. Is anything under 1000ms acceptable for IPC / ISA application? and BTW, what is VMC CPU time? For IPC, is it the time to price a whole sales order? or an item? in case of web catalog using IPC pricing, when displaying the web catalog, is VMC CPU time the time needed to calculate all prices of all products in the catalog?
Thanks
Jayson
