Performance Considerations
You should have prior experience tuning the performance of the OpenVMS
operating system

For general information on OpenVMS performance, see the
OpenVMS Performance Management Manual at the following URL:

Limits and Quotas
The following table shows sample values for the ORACLE Account from a working
and exercised Oracle HTTP Server with a light to moderate load

These values are
presented as an example of a system performing well within its context

If you
should experience performance difficulties, refer to this table for guidelines in

For heavier loads, we point out which values, in our
experience, need to be increased as load increases
.
Keep in mind that no one set of
values will be appropriate for all situations.

because it limits BIOLM,DIOLM, and
