Testing applications on z/OS

You can test applications on IBM® z/OS® systems by using the mainframe support capabilities of Rational® Integration Tester. Rational Integration Tester is installed as part of the IBM Rational Test Workbench product offering.

Note: For information on recording requests from a non-z/OS queue manager to a queue on a z/OS queue manager and virtualizing replies from z/OS to a queue on a non-z/OS queue manager without installing the HRVMMQF exit, see Using WebSphere MQ transports on distributed platforms to test traffic to and from WebSphere MQ on z/OS.

Rational Integration Tester supports the following features when running on z/OS 2.1 and 2.2:

CICS® Transaction Gateway recording, stubbing, and test execution
CICS Transaction Server Distributed Program Link (DPL) recording and stubbing
CICS IP interconnectivity (IPIC) recording and testing
CICS web services
IMS™ Connect recording
IMS Connect transport
WebSphere® MQ queue manager message recording from either a single queue manager or from a queue sharing group.
IBM z/OS Connect Profile
Sift-and-pass-through functionality (for more information, see Sift-and-pass-through capability)

For more information about z/OS, CICS, and IMS, see IBM z/OS basic skills education knowledge center.

Hardware requirements

No special hardware is needed for any of the z/OS features that are supported by Rational Integration Tester .

For general information about Rational Integration Tester’s hardware requirements, see Installing Rational Test Workbench.

For information about z/OS hardware requirements, go to IBM z/OS basic skills education knowledge center.

Software requirements

This section explains the software requirements for z/OS and Rational Integration Tester.

z/OS must be installed and configured. For more information, see IBM z/OS basic skills education knowledge center.

Rational Integration Tester and IBM Rational Test Control Panel must be installed.

The following software versions are supported:

IBM WebSphere MQ 7.1, 7.5, and 8.0
CICS Transaction Gateway 8.0, 8.1, 9.0, 9.1, and 9.2
CICS Transaction Server versions 4.1, 4.2, 5.1, and 5.2 for IPIC and DPL
IMS 12, 13, and 14 (includes IMS Connect) with the Java API included in IBM IMS Enterprise Suite 2.1, 3.1, or 3.2

The following table describes more requirements for performing specific testing activities.

To perform these actions	Install
Record IMS Connect traffic by using the HTTP/TCP proxy	IBM Rational Test Control Panel HTTP/TCP proxies
Record inbound or outbound IPIC communications to or from CICS programs
Record inbound or outbound web service calls to or from CICS programs
Run tests and stubs on non-local systems	Rational Integration Tester Agent
