Description
NSERVS specifies the number of servers.
When NSERVS is not set explicitly, Model 204 gives it a value equal to the setting of NUSERS. NSERVS cannot be set to a value greater than NUSERS — if you try to do so, the parameter gets reset to the value of NUSERS during Model 204 initialization. The NSERVS minimum value is 1.
The algorithm to determine if NSERVS, NUSERS, and NSUBTKS are too large is:
IF NUSERS=NSERVS NUSERS + NSUBTKS + 1 > 32767 ELSE NSERVS + NUSERS + NSUBTKS + 1 > 32767
If too many process control blocks are requested, the user receives the following message:
M204.0021: NSERVS+NUSERS(IF SWAPPING)+NSUBTKS+1 > 32767
Each server, user, pseudo subtask, and the Scheduler has a process control block. There may not be more than 32767 process control blocks.
If you receive the M204.0021 message, adjust the combination of NUSERS, NSERVS, and NSUBTKS + 1 so that it does not exceed 32767.
