I have a question for ORACLE's memory usage. Our customer uses 100% of CPU on VAX6610 and 8-9 process is waiting CPU. I heard ORACLE uses many memory in order to make I/O fast. Anyone has ORACLE memory guideline or recommendation for SYSGEN PARAMETER about buffering ? regards, Tatsukawa/Sales support for Mutinational Busienss Sales division in Japan.

TATSUKAWA,
Are those 8-9 processes waiting in a COM state? If so you most likely
need more CPU power.
What is the CPU doing: paging, swapping, application I/O, compute
bound, are there disk channel/drive I/O queues, is there any free
memory (if get more)? Do you have a local capacity planning expert? A
CPU that is 100% used is not the best practical way to run a system.
The last time I saw ORACLE manuals, they did have some guidelines for
setting SYSGEN PARAMETERS on VMS.
regards,
Ken
