CONCLUSION 4. {R0010}

The system fault rate for VMS is over 2 faults per second for the following time periods. Performance can be improved for the whole system if the VMS fault rate can be reduced.

Increase the working set size for VMS (SYSMWCNT) to reduce the system fault rate. Do this by adding an entry in MODPARAMS.DAT similar to "ADD_SYSMWCNT = 100", and running AUTOGEN. The "100" is

just an initial guideline. Total number of samples giving this conclusion: 12 Current setting of this system parameter: 730 CONDITIONS

The following statements are keyed to the columns in the Miscellaneous Rule analysis report:

  1. Average number of times per second that a page fault (hard or soft) occurred for the OpenVMS system working set.
  2. Beginning time of the interval in which the condition occurred.
