Problem Detection in CICS Using the XMON Feature of Explore for CICS

Products

• Explore Performance Management for z/VSE

Issue/Introduction

The XMONITOR (or XMON) command can be used to display a quick overview of all CICS partitions running Explore Performance Management for CICS. This panel provides a single point from which problems in a number of CICS partitions can be identified quickly.

 

Resolution

For example, typing XMON from the command line of EXPLORE displays the following:

                                 Extended Monitor Status                  
1:2/2-DATA
    Name             Type      PartId     Time         Count         Status
_  CICSPROD          CICS      F2         15:12:29     20            Problem 
_  CICSDEV           CICS      F4         15:12:29     20            Ok

Selecting the CICSPROD partition above (the one with the problem), a detailed breakdown of the status of each resource monitored is displayed. This helps in identifying the problem area quickly. The statuses of the resources in the CICSPROD partition include:

   Resource                  Value        Limit               Status
_  Exceptions                    4
_  Max Tasks                                                  Ok
_  CPU%JOB                      36           30               Problem
_  DSA%                         75           99               Warning
_  FILEREQS                1800000        10000               Warning
_  GETV24%                      66           95               Ok
_  GETV31%                      79           95               Warning

Selecting the resource CPU%JOB displays the current tasks running in the CICSPROD partition.

Tran   Task#  Term   Program   Wait Type   Name........   SVM TYP       CPU  LifeTime
