Description

The IODEV parameter supports duplication within a single device type. The DUPTERM parameter indicates the number of duplications.

As of version 7.4, if DUPTERM is specified on the first IODEV parameter line of a particular type, then the NOTERM parameter must also be present. Otherwise, the IODEV line is rejected with the message:

M204.2651: NOT ALL THREADS PROCESSED FOR IODEV x

and the Online will terminate.

Example

In the following example:

  • NUSERS=15 represents User 0, three IODEV43s, seven IODEV41s, and four IODEV7s.
  • IODEV=43 is defined without using the DUPTERM parameter.
  • IODEV=41 is defined using the DUPTERM parameter by specifying the DUPTERM=nnn, where nnn is the number of times a terminal is duplicated.

Notice that NOTERM must be defined on the first IODEV line, and it must indicate the total number of similar devices to be defined. In addition, POLLNO is no longer required. (It increments from 1 for each new IODEV.)

NOTERM=3,IODEV=43 IODEV=43,SERVSIZE=100000 IODEV=43,POLLNO=3,SERVSIZE=50000 <- POLLNO verified NOTERM=7,IODEV=41,DUPTERM=2,SERVSIZE=50000 <- plus 2 identical devices IODEV=41,SERVSIZE=75000 IODEV=41,DUPTERM=2,SERVSIZE=100000 <- plus 2 identical devices NOTERM=4,IODEV=7,DUPTERM=3 <- plus 3 identical devices

The following CCAPRINT change occurs when DUPTERM is used:

USER 4 NOTERM=7,IODEV=41,DUPTERM=2,SERVSIZE=50000 NOTERM 7 NUMBER OF TERMINALS ON LINE IODEV 41 TYPE OF I/O DEVICE DUPTERM 2 NUMBER OF DUPLICATE TERMINALS <- different SERVSIZE 50000 MAXIMUM SIZE OF THIS SERVER USER 5 DUPLICATED <- different USER 6 DUPLICATED <- different USER 7 IODEV=41,SERVSIZE=75000 IODEV 41 TYPE OF I/O DEVICE SERVSIZE 75000 MAXIMUM SIZE OF THIS SERVER
