Before you can install and use Z Code Optimization Advice, ensure all prerequisites are met.

Local host requirements

  • Microsoft Visual Studio Code, version 1.86.0 or above
  • 2.3+
    • Zowe™ Explorer VS Code extension, version 3.0.0 or above
    • IBM Z Open Editor extension, version 5.0.0 or above
  • 2.1+
    • Zowe Explorer VS Codeextension, version 2.16.0 or above
    • IBM Z Open Editorextension, version 4.3.0 or above
  • Zowe CLI 7.24.1 or above
  • Windows 10 or above, or MacOSX
Note: If you have installed the IBM Z Open Editor and Zowe Explorer extensions from the IBM® watsonx Code Assistant™ for Z product package, then these prerequisites will likely already be installed. If not, proceed to install and configure them before continuing.

User authorization

Users must be authorized to be able to submit JCL using TSO/E commands. For information on how to enroll users to TSO/E, refer to Overview of enrolling users through the Information Center Facility. For information on authorization settings in TSO/E, refer to TSO/E authorization information.

z/OS host requirements

  • IBM z/OS 2.4 or above
  • IBM Z server 14 or above
Note: Installing the z/OS host package on a z/OS LPAR is recommended for accurate results.

2.4+

Installations of the z/OS host package can also be made on emulated environments through a zPDT or zD&T machine, however, performance measurements and problem priority may be inaccurate compared to profiling on IBM Z hardware.

Code page configuration

Z Code Optimization Advice uses the VS Code default code page 1047. If another code page is used, it may prevent Z Code Optimization Advice from being able to process the report.
Note: If you are unable to open the optimization report in VS Code, check your configuration and ensure code page 1047 is used. To reconfigure the code page, refer to Zowe Explorer profiles.

Connecting your Zowe profile with z/OS

To make use of Zowe to open and edit files directly from z/OS MVS or USS, you need the Zowe client software and either IBM RSE API or z/OSMF configured. For more information, refer to Installing Zowe CLI and VS Code Extension for Zowe. Once installed, follow the instructions at Interacting with z/OS to create a Zowe CLI team configuration file so that data sets can be found and accessed.
