Specifying the subsystem parameter load module for a member

Every member of a data sharing group must have its own unique load module for subsystem parameters (sometimes called DSNZPARM in a non-data sharing environment).

About this task

The load module for subsystem parameters is built by job DSNTIJUZ and stored in the prefix.SDSNEXIT target library. Every member must use a different name for its parameter load module because the prefix.SDSNEXIT target library can be shared among all members of the data sharing group. The installation process requires that you provide the name of the load module for a member.

Recommendation: Name each member's load module using the convention DSNZPxxx, where xxx includes the number in the member name and the group identifier. For example, DB1A's subsystem parameter load module could be named DSNZP01A.

The subsystem parameter load module name for a member is an optional parameter on the EXEC statement in the JCL procedure that is used to start the system services address space (ssnmMSTR). This optional parameter provides support for an operator (or automated operations) not specifying the subsystem parameter load module name when starting a member.

Procedure

To specify the subsystem parameter load module for a member:

Specify the load module name in the EXEC statement of the ssnmMSTR JCL procedure in SYS1.PROCLIB as follows:

//IEFPROC EXEC PGM=DSNYASCP,PARM='ZPARM(DSNZPxxx)',...
