CA/XMANAGER 20.0 PXMQMGCC FAILURE DIAG/DUMP

Products

• Detector for DB2 for z/OS

Issue/Introduction

Getting this message in the Xmanager task: 

PXM3205 DETECTOR COLLECTION TASK STALLED TSKNBR=00 DB2=XXXX 

then it abends. What can be causing this?

 

Environment

z/os db2 20.0

Resolution

This is usually caused by a dispatching priority problem with the Xmanager 

The operating system dispatching priority assigned to the Xmanager address space can be of concern when collection is active. 

Selected collection components executing within the Xmanager address space require CPU cycles to be obtained at a comparable level to the application workload being generated.
