TPX address space experiencing high CPU

Products

• TPX - Session Management

Issue/Introduction

In a TPX Generic Resource environment, one of the TPX images is experiencing high CPU usage.

Environment

Release : 5.4

Component : CA-TPX for Z/OS

Resolution

This is symptomatic of a TPX VSAM database (ADMIN!, ADMIN2....etc) not being reorged in a very long time.

One of the most common reasons among many, can be that a user record is locked or corrupted, causing the TPX 'monitor' queue backing up, resulting in wait time for processing.
The Ci/CA splits in the VSAM database need to be attended to in order to avoid unpredictable results. A Reorg will eliminate the condition.

Review the recommended procedures in the Additional information section below, for keeping the TPX VSAM database healthy.
