QNAME parameter - IBM-JCL

Parameter Type
Keyword, optional

Purpose
Use the QNAME parameter to indicate that this DD statement defines a data set of telecommunications access method (TCAM) messages. The QNAME parameter refers to a TPROCESS macro instruction that defines a destination queue for the messages. Optionally, the QNAME parameter can also name a TCAM job to process the messages.

1.Syntax

QNAME=procname[.tcamname]

2.Subparameter Definition

procname
Identifies a TPROCESS macro instruction; procname must be identical to the procname in the name field of the TPROCESS macro instruction.

tcamname
Names a TCAM job: tcamname must be identical to the jobname. The TCAM job can be a task started by an operator START command.

3.Relationship to Other Parameters
The only DD parameters that you can code with the QNAME parameter are DCB, LIKE, LRECL, RECFM, and REFDD. The only DCB subparameters that you can code with the QNAME parameter are: BLKSIZE, BUFL, LRECL, OPTCD, and RECFM.

4.Examples of the QNAME Parameter

Example

//DYD DD QNAME=FIRST,DCB=(RECFM=FB,LRECL=80,BLKSIZE=320)

This DD statement defines a data set of TCAM messages. FIRST is the name of the TPROCESS macro instruction that specifies the destination queue to which the messages are routed. The DCB parameter supplies information not supplied in the program’s DCB macro instruction for the data control block.

Example

//DXD DD QNAME=SECOND.TCAM01

This DD statement defines a data set of TCAM messages. SECOND is the name of the TPROCESS macro instruction that specifies the destination queue to which the messages are routed. TCAM program TCAM01 will process the messages.
