Description
The total number of User Language users and Host Language Interface IFAM2 or IFAM4 threads to be supported by Model 204.
Usage notes
- 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.
- NUSERS affects the return code set by M204. and MSIR. messages. When NUSERS=1, the Batch return code for the message is set. When NUSERS>1, the Online return code is set unless CUSTOM=22 has been specified in CCAIN. In that, case, the Batch return code is set. The return code is not changed if the message specifies a return code less than the current setting of the return code for the run.
- NUSERS-1 should equal the number of IODEV lines defined. If NUSERS is set to a number greater than the number of IODEV lines, the next input line receives an error:
- If DUPTERM is not used, the extra IODEV lines are ignored.
- If DUPTERM is used, you are notified that not all the threads for a specified IODEV are processed.
- If DUPTERM and FUNTSKN are specified, the extra IODEV lines are used for Fast/Unload tasks, and you are notified if some other threads do not open.
M204.2489: IODEV parameter expected.
If the number of IODEV lines exceeds NUSERS:
