Using REGPRODS command to manage product registration

Products

• SYSVIEW Performance Management

Issue/Introduction

How to delete or change a product from the SYSVIEW REGPRODS list after it was added.

Environment

SYSVIEW Performance Management, all releases

z/OS

Cause

The SYSVIEW REGPRODS ADD subcommand is a dynamic method to add a product to the registry for the duration that the user is logged on.   Because it is a dynamic command, there is no DELETE subcommand.

Resolution

Overview

The REGPRODS command in SYSVIEW Performance Management provides visibility into currently running registered products on an LPAR. While products typically use IBM callable services to register and deregister themselves automatically, there may occasionally be a need to manage these registrations manually for testing or verification purposes.

Managing Product Registrations

Viewing Registered Products

Use the REGPRODS command to display the list of products currently registered in the IBM Function Registry for z/OS. This list reflects products that have dynamically registered themselves at startup.

Adding Products Dynamically

To manually register a product for the current session, use the ADD subcommand as documented in the SYSVIEW Performance Management Command Reference manual.  

Modifying or Deleting Products

There is no specific DELETE or MODIFY command for entries added via REGPRODS ADD. Dynamically registered products are managed based on the following behavior:

• Automatic Removal: According to IBM documentation, a dynamically added product registration is automatically removed when the associated job or TSO session ends. Logging off and back on will clear manually added entries.
• Permanent Registration: For a product to remain registered across sessions, it must be defined in the SYS1.PARMLIB member IFAPRDxx rather than only being added manually via SYSVIEW subcommands.

Troubleshooting and Verification

• Persistence Check: If a manually added product is no longer visible after a TSO re-log, this is expected behavior as designed.
• Registry Scope: The REGPRODS display focuses on the IBM Function Registry and may not include every installed application if those applications do not utilize dynamic registration services.
• Alternative Commands: To view general product registration and status outside of SYSVIEW:
•                            /D PROD,REG or /D PROD,STATE can be utilized.
