Introduction

This information is specific to Universal Connector for SAP (USAP) for the z/OS operating system.

Usage

Universal Connector for SAP for z/OS executes as a batch job.

Each batch job contains:

  1. JCL interface to the command line.
  2. Configuration options associated with the specified command.
  3. Configuration options (required and optional) not associated with any specific command.

Universal Connector for SAP performs an operation specified by the command. The configuration options describe the actions to take for that operation.

This section describes the JCL and command line syntax of Universal Connector for SAP for z/OS.

JCL Procedure

The following figure illustrates the Universal Connector for SAP for z/OS JCL procedure (USPPRC, located in the SUSPSAMP library) that is provided to simplify the execution JCL and future maintenance.
 

//USPPRC   PROC UPARM=,               -- USAP options
//             SAPRFC=USPRFC00,       -- SAP RFC member
//             USAPPRE=#SHLQ.UNV,
//             USAPPRD=#PHLQ.UNV
//*
//PS1      EXEC PGM=USAP,PARM='ENVAR(TZ=EST5EDT)/&UPARM'
//STEPLIB  DD  DISP=SHR,DSN=&USAPPRE..SUNVLOAD
//*
//UNVNLS   DD  DISP=SHR,DSN=&USAPPRE..SUNVNLS
//UNVRFC   DD  DISP=SHR,DSN=&USAPPRD..UNVCONF(&SAPRFC)
//UNVTRACE DD  SYSOUT=*
//*
//SYSPRINT DD  SYSOUT=*
//SYSOUT   DD  SYSOUT=*
//CEEDUMP  DD  SYSOUT=*

 
The parameter UPARM specifies EXEC PARM keyword values. The parameter CONFIG specifies the configuration member. The parameter SAPRFC specifies the SAP RFC configuration member. The parameter USAPPRE specifies the data set name prefix of USAP installation data sets.
