Description
The number of servers
When NSERVS is not set explicitly, Model 204 gives it a value equal to the setting of NUSERS. Never set NSERVS greater than NUSERS. Its 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 have been 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.
