Hello listers,
Over the weekend, we migrated a couple of large SAP systems from SLES10 SP4 to SLES11 SP2. These are large SAP application servers (22GB). Our SAP folks have a transaction that can be used to measure SAP response time. Our servers are grouped by the applications they run. Intermittantly one of the SAP application servers in one group will for a while have a response time that is about 3 times larger that the SLES10 systems. 1600 ms vs 500 ms. The other sles11 system in the other application group will have a response time that is around 700 ms, and the others in the group have around 350 ms. After a few minutes the response times on the SLES11 systems return to normal. I start to look at things. I issue the vmstat command and find something. The in column in the system area is all zeros. The man page says that this is the number of interrupts per second. Anyone else experience response time problems, or not get the interrupts information?
