The Question is:
We are currently have user interactive limit set at 128. If I increase this
limit, but the user usage does not actually change, what affect if any does
the increase of the interactive user limit have on system performance?
The Answer is :
You will potentially see improvements with upgrades to more recent
OpenVMS releases, as there have been various significant performance
enhancements implemented in more recent OpenVMS releases.
As for simply increasing the interactive user limit IJOBLIM, it is
simply a counter and a limit -- OpenVMS itself does not particularly
depend on nor particularly use the value for any purpose other than
as a limit, but it is possible that specific applications might use
the value to size application-specific structures or constructs.
(More commonly, the OpenVMS Wizard would expect applications will
use MAXPROCESSCNT and not IJOBLIM for sizing purposes, however.)
For general performance and tuning information and an introduction
to systematic system tuning, please see the performance manual.
