DT005E Xmanager unavailable message entering DT or SA from the Database Management Solutions main menu

Products

• Detector for DB2 for z/OS
• Subsystem Analyzer for DB2 for z/OS
• Database Management for DB2 for z/OS - Performance Suite

Issue/Introduction

Receive error DT005E Xmanager unavailable when entering either DT for Detector for Db2 for z/OS (PDT) or SA for Subsystem Analyzer for Db2 for z/OS (PSA)
from the Database Management Solutions for Db2 for z/OS RSPMAIN menu. The problem only occurs for the two newly added Db2 subsystems and is limited to
only Detector and Subsystem Analyzer.

Cause

The DT005E Xmanager inactive message will occur, entering DT Detector or SA Subsystem Analyzer, if the Xmanager started task(s) are not recycled
after introducing a new Db2 subsystem to an LPAR.

Resolution

If the Xmanager started task is already up and running when a new Db2 subsystem is created, the Xmanager started task must be recycled to discover the new subsystem. 
This will alleviate the DT005E Xmanager unavailable message.
