Pipe usage through JCL
Pipes can be used through JCL with or without a Pipe Rule.
By coding the SUBSYS parameter in the JCL DD statement, a data set will be replaced by a pipe.
The only required parameters in the DD statement are DSN and SUBSYS. The SUBSYS parameter should specify the Job Optimizer Pipes Subsystem name (as defined in the BatchPlex member BPSSIDR parameter) and the subsystem parameter PRTYPE that contains the participant type. The following code shows an example:
// SUBSYS=(MBOP,'PRTYPE=WTR'),
// DCB=(LRECL=80,BLKSIZE=800,RECFM=FB)
In this example, the participant is identified as a writer by the PRTYPE subsystem parameter. If a Pipe Rule exists for this data set, the pipe parameters are determined according to the Pipe Rule and the Pipe Rule defaults. If no Pipe Rule is defined for this data set, all required parameters are taken from the Pipe Rule defaults.
