Software requirements

This section lists the software requirements for WebSphere MQ. We recommend that you use one of the packaged offerings of z/OS from IBM (for example, ServerPac). This includes most of the products that we need to run WebSphere MQ for z/OS, and the integrated products have been verified by IBM.

The list of elements included in z/OS, and the recommended levels of nonexclusive elements are described in the z/OS and z/OSe Planning For Installation manual.

WebSphere MQ for z/OS, V6.0 requires z/OS V1.4 or later, together with the products included in z/OS. These include:

• C/C++

• optionally Cryptographic Services System SSL (if you want to use the Secure Sockets Layer (SSL) for channel security)

• optionally Cryptographic Services Security Level 3 (if you want to use SSL for channel security with US encryption strengths)

• DFSMS/dfp

• High Level Assembler

• ICSS

• ISPF

• JES

• Language Environment (previously known as LE/370)

• Security Server (previously known as RACF)

• SMP/E

• Optionally TCP/IP (see Communications protocol and distributed queuing)

• TSO/E

• UNIX System Services

• VTAM

The following list gives the minimum levels required for the optional products that are not included in z/OS. We can also use any more recent versions of COBOL and PL/I compilers that can generate calls to WebSphere MQ conforming to the standard operating system linkage conventions described in the z/OS MVS Assembler Services Guide. You might not need all the following:

• CICS Transaction Server V1.3

• COBOL:

  • IBM SAA AD/Cycle COBOL/370

  • VS COBOL 2, V4

  • IBM COBOL for OS/390 (z/OS) and VM, V2.1

  • IBM COBOL for MVS and VM, V2.1

• IMS, V7.1

• IBM PL/I for MVS and VM, V1.1 (5688-235)
