Issue/Introduction

How to get reports on the four IBM Health Checks issued by an IDMS CV?

Environment

Release: All supported releases

Resolution

There are a variety of facilities to report results of Health Checks:

SDSF CK command 
HZSPRINT Utility 
Health Checker log stream 
CA SYSVIEW

This document will show examples of how to look at Health Checker results using CA SYSVIEW and the IBM HZSPRINT utility.

The messages issued at CV startup will show you the checks that have been registered. Each of the four Health Checks described in RO12080 and in APPENDIX A of the 17.0 SP1 SYSTEMS OPERATIONS GUIDE will be appended with the SYSTEM ID of the IDMS system you run.

Example:

DC024000 V1700 T0 HEALTH CHECKER: Infrastructure initialized            DC024000 V1700 T0 HEALTH CHECKER: Added check routine IDMS_SCRATCH_IN_MEMORY@SYST1700DC024000 V1700 T0 HEALTH CHECKER: Added check routine IDMS_CPU_EFFECTIVENESS@SYST1700DC024000 V1700 T0 HEALTH CHECKER: Added check routine IDMS_CHANGE_TRACKING@SYST1700DC024000 V1700 T0 HEALTH CHECKER: Added check routine IDMS_ZIIP_USAGE@SYST1700DC024000 V1700 T0 HEALTH CHECKER: All check routines registered

SYSVIEW:

From the main SYSVIEW menu, select "2 Menu MVS":

From the MVS menu select "12 MENU HCHECKER"

From the Health Checker menu select "1 HCOWNER"

From the HCOWNER screen, select CA_IDMS

Select any of the individual checks to see results.

 

Examples of running the batch utility HZSPRINT.

This utility accepts a parameter that is either the full CHECK_OWNER,CHECK_NAME or a wildcarded filter.

JCL to run the job is very simple.

Here is an example with the full owner and check name:

//HZSPRINT EXEC PGM=HZSPRNT,TIME=1440,REGION=0M,           
//        PARM=('CHECK(CA_IDMS,IDMS_CHANGE_TRACKING@SYST####)') 
//SYSOUT   DD SYSOUT=*,DCB=(LRECL=256)

This job produced the following output:

  This job produced the following output: *************************************************************************

DC200024 CA IDMS Change Tracking is in use. Change tracking enables changing the database environment of a Central Version (CV) in a fault-tolerant manner. Specifically, it permits the DBA to perform the following dynamic actions:

• Vary the data set name of a journal or database file within a CV without introducing the need for manual intervention in the case of a CV failure.
   
• Vary a new version of a Device Media Control Language module (DMCL) without introducing the potential for a warmstart failure. 
   
• Vary the status of an area or segment permanently on a CV without regard to subsequent page range changes. 
   
• Change the journal files in use by a CV and coordinate those changes with the associated archive journal jobs.

If the CV fails, the runtime database definition is restored from SYSTRK files during restart, ensuring that the files being updated at the time of failure are the ones recovered by warmstart unless explicitly 
overridden by changes in the JCL used to restart the CV.

If you were to run this JCL with an '*' after the CHECK_NAME instead of the '@' and SystemID it would produce a report for ALL IDMS CVs that issued that check.

Example:

//HZSPRINT EXEC PGM=HZSPRNT,TIME=1440,REGION=0M,
//    PARM=('CHECK(CA_IDMS,IDMS_ZIIP_USAGE*)')  
//SYSOUT   DD SYSOUT=*,DCB=(LRECL=256)

To see ALL checks issued by all IDMS CVs on the LPAR you can specify a single '*' for Check_name:

//HZSPRINT EXEC PGM=HZSPRNT,TIME=1440,REGION=0M, 
//    PARM=('CHECK(CA_IDMS,*)')   
//SYSOUT   DD SYSOUT=*,DCB=(LRECL=256)
