Preinstallation considerations for Compuware Program Analyzer

This topic lists the preinstallation considerations for installing the mainframe portion of Program Analyzer.

Refer to the release notes for the most current system requirements.

Program Analyzer requires IBM TCP/IP communications.

Tip

Program Analyzer must be installed on the same MVS image as IBM TCP/IP for MVS and Compuware’s Host Communication Interface (HCI).

Connect to MVS Host

Before you install Program Analyzer on the MVS host, you must have a connection (link) between the host on which you will install the mainframe component of Program Analyzer and the workstation on which you will install the workstation component.

TP definitions using TCP/IP

The communication between the workstation and the host is done through a TP. It uses the TCP/IP communication protocol. You must be able to run TCP/IP traffic from the workstation to the host. The Windows PING command is one way to test this. Refer to the help topic entitled Ensuring TCP/IP connection from the workstation to the MVS host for information on how to verify workstation to host connectivity.

Tip

To avoid any unpredictable connection issues, make sure all current IBM maintenance is applied to TCP/IP.

Overview of HCI

Program Analyzer uses Compuware’s Host Communications Interface (HCI) to provide connectivity between the workstation and the mainframe, using TCP/IP as the communications protocol.

HCI is a component of Enterprise Common Components. Refer to the Enterprise Common Components Installation and Configuration Guide for more information about HCI.

The design of HCI is based on facilities available to z/OS operating systems. Refer to the software requirements for MVS host in the release notes for additional information.

  • HCI itself can be started as a started task or as a batch job.
  • HCI starts transaction programs (TPs) as started tasks or as batch jobs.
    Started task transaction programs can also be set up with master scheduler JCL using the IEFJOBS DD concatenation of MSTJCLxx. Refer to the step detailing how to set up started task TPs with master JCL on Step 2. Define Dataset Names.
  • When using HCI, the HCI address space must be authorized by the Authorized Program Facility (APF). However, the application programs or the link-edited interface modules using HCI are not required to be APF-authorized. These are normal MVS non-authorized programs.
