We have a DEC 4000/610 with OSF/1 V1.3 running Oracle7 7.0.15.4.
We have about 55 interactive SQL*Forms 3.0 users and we run at the same
time about 5..10 batch reports. We use MTS with 10 server processes. We
have 196 MB RAM and the exp dump file size is about 500MB.
We have a performance problem: when we have many large batch reports
running the interactive response time is slow. And when I look at
"vmstat" output, the run queue is about 15. I think that the problem is
that the big reports are very CPU intensive (after having loaded all
their data into Oracle databases buffers in RAM) and that they use all
of their CPU timeslice. So the interactive processes have to wait long
before they get their slice of the CPU - i.e. the run queue is long.
How do I reduce the maximum timeslice a CPU-intensive process can get in
OSF/1? I read man an hour yesterday without getting any info. They
referred to a printed manual which I don't have at hand.
Another question: would upgrading to OSF/1 V2.X & Oracle 7.0.16.4 affect
performance in any way?
