Hello, I sent a note before, but I don't know if my messages are blocked. I have a very simmilar situation: - z/VM 5.1 (4G real, 2G expanded) - Guest Linux SuSE 8 with Oracle 10g. Definition of 2G and SGA 1.7G (I know is big, but it's the one with better results) - zSeries 800 with 2 IFL If I have this storage in the guest, I have CPU at 100%. If I decrease storage in the guest (and reduce SGA), it increases access to dasd, and bad response time. Any help is welcome. ---Mensaje original---thanx

Indexes could be missing, the optimiser could be using a different approach.
