Issue/Introduction

Please explain as to how you can see whether the RMOPARM SUBSYS is turned on or not, as to what purpose the parameter serves, and as to the benefits of using it. 

Environment

Release : 14.0

Component :

Resolution

For background, the JCL SUBSYS parameter can be used to process a dataset or a sysout dataset:

 . //DD1   DD  DSN=...,SUBSYS=ABC

 . //DD1    DD  SUBSYS=(ROP1,...). 

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

The format of the RMOPARM SUBSYS parameter is:

   SUBSYS=name/class/dest/form/writer

This initialization parameter will allow Deliver to capture data written to a DD statement with the SUBSYS keyword.

Certain other output management products utilize SUBSYS data sets to send information to their product.

Previously, Deliver did not allow capture of this data, so Deliver could not be run in parallel with those output management products.

This now provides Deliver with a new way of processing, to allow it to work with these types of data sets, in addition to SYSOUT data sets.

----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

For a Deliver RMOPARM parameter, to see if the parameter is in use, in a running RMOSTC task, issue "/F rmostc,DISPLAY" to see the list of active parameters. 

Regarding the specifics of the enhancement, in PTF LU01737:

 . SUBSYS is used in a pre-spool processing environment. 

 . Subsystem data sets (SUBSYS JCL statements) have the same capabilities as SYSOUT data sets, in that all of the Deliver report types can be created, and all the output possibilities are available.

 . Note: Only one subsystem can be intercepted by a single Deliver started task.
