Software requirements

A current version of Micro Focus Mainframe Access (MFA) Server installed. See Installing Mainframe Access Server and Configuring and Administering the Mainframe for more information.

An IBM supported operating system z/OS (V1.13 or later) is required, with the following components installed:

• ISPF
• Binder
• High Level Assembler
• Language Environment
• RACF or an equivalent product
• z/OS Communications Server - IP Services
• IBM REXX Library

To run user applications requested via TCP/IP client calls, there may be additional optional software requirements depending on the application. Typical optional requirements are:

• IBM Enterprise COBOL for z/OS
• IBM Enterprise PL/I
• IBM DB2 for z/OS

Support for Error Feedback (displaying compiler error messages in an Enterprise Developer error view) requires the following additional compiler options:

• For COBOL: EXIT(ADEXIT('/N 100 /W 50',TAURTOCX)), ADATA
• For PL/I: XINFO(XML)
• For Assembler: EXIT(ADEXIT(TAURTOAX('/N 100 /W 25'))),ADATA

To compile CICS applications, a compiler supporting the CICS Transaction Server 2.1 or later is required:

• COBOL applications compiled using any of:
  • IBM® COBOL for OS/390® &VM, Version 2 Release 2, program number 5648-A25, with APAR PQ49375 applied.
  • IBM Enterprise COBOL for z/OS and OS/390, Version 3 Release 1, program number 5655-G53, and later COBOL releases.
• PL/I applications compiled using any of:
  • IBM VisualAge PL/I for OS/390 Version 2 Release 2.1, program number 5655-B22, with APAR PQ45562 applied.
  • IBM Enterprise PL/I for z/OS and OS/390, Version 3 Release 1, program number 5655-H31, and later PL/I releases.

To use the integrated CICS translator for COBOL, you must specify the compiler options CICS, LIB, NODYNAM, and RENT. To use the integrated CICS translator for PL/I, you must specify the compiler option SYSTEM(CICS).

To compile DB2 applications, a compiler supporting the DB2 integrated pre-processor is required. It can be used with DB2 V10 and above with:

• C/C++ C/C++ (without Debug Tool).
• COBOL Enterprise COBOL for z/OS Version 3 Release 4, program number 5655-G53, or Enterprise COBOL Version 4 Release 1, program number 5655-S71, or later.
• PL/I Enterprise PL/I for z/OS Version 4 Release 1, program number 5655-W67, or Enterprise PL/I for z/OS Version 3 Release 7, program number 5655-H31, or later.

This installation guide applies to V2R2U2 of z/Server. For this modification level, you need to run all address spaces at the same software level. Mixing this level with lower modification levels is not supported.

To run modeled ISPF applications using the AWM client successfully, the Language Environment run-time option NORTEREUS must be set as a system-wide default. z/Server does not support modeled applications when RTEREUS (instead of NORTEREUS) is explicitly set in CEEDOPT.

If running z/Server on a z/OS release prior to 1.13, correct behavior is not guaranteed. As a minimum, the ptfs for PK90754 with all its prerequisites must be applied (Prerequisite inside LE).
