Hello, I'd like to know if there's anybody using Oracle under Linux and z/VM. Our situation is: -Oracle 10g - SuSE 9 - z/VM 5.1: zSeries 800, 2 IFLs, 4.6 GB of central storage, 1,5 GB of expanded storage, 6 ESCON channels, DS/8000 storage. - At this moment, there's another VM guest with 1 GB in size. The database is 176 GB in size, used for datawarehouse. The common accesses are transactional (short term requests) both in queries and updates. The results of our performance tests are bad (in words of our DBA, because my problem is that I have no knowledge of Oracle, so I only know what my DBA tells me). What I can observe from Performance Toolkit is that we have a high rate of pages moving from central to expanded, and from expanded to central, causing a high CPU use. At this moment, I'm aplying fixes UM31411 and UM31485 because they are commended for this kind of problems. Any help would be welcome, because I have tried everything, and I don't know what could be the problem.
