The Question is:
What is the sysgen parameter to disable automatic working set sizing?
The Answer is :
There are various system parameters associated with the memory management
system and with the process working set management, and there are system
services and other mechanisms that can potentially either be involved or
be of interest here. Some examples of options include the AWS*, PF*,
WS*, SWPOUTPGCNT and other system parameters, the sys$setswm, sys$lckpag,
sys$adjwsl, and sys$lkwset system services, the DCL commands SET
WORKING_SET/NOADJUST and SET PROCESS/NOSWAPPING, etc. Real-time process
priorities also avoid quantum-end processing, meaning that the real-time
processes will typically avoid working set adjustments while operating.
The OpenVMS Internals and Data Structures Manual (IDSM) can be of interest
here, and will potentially provide you with one or more options for your
particular application requirements.
Please contact the support center. You will want to expect to be asked
for details of and background for the particular problem(s) here.
