Description

The total number of User Language users and Host Language Interface IFAM2 or IFAM4 threads to be supported by Model 204.

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.
