Collecting diagnosis information

If you suspect that there is a problem within the MVS™ system logger that is not a result of some other resolvable problem, you might need to collect additional diagnostic information.

The dumps generated by CICS® VR generally do not contain sufficient information about the MVS system logger.

A dump of XCF and MVS system logger address spaces from all systems are useful in the diagnosis of such problems. Issue the following series of MVS commands:
      DUMP COMM=(meaningful dump title)
      R ww,JOBNAME=(IXGLOGR,XCFAS,CICSVR_jobname),DSPNAME=('XCFAS'.*),CONT
      R xx,STRLIST=(STRNAME=structure,(LISTNUM=ALL),ACC=NOLIM),CONT
      R yy,REMOTE=(SYSLIST=*('XCFAS','IXGLOGR'),DSPNAME,SDATA),CONT
      R zz,SDATA=(COUPLE,ALLNUC,LPA,LSQA,PSA,RGN,SQA,TRT,CSA,GRSQ,XESDATA),END

Use the R xx,STRLIST=(STRNAME=structure,(LISTNUM=ALL),ACC=NOLIM),CONT instruction only where you suspect a problem with the coupling facility structure.

Error records written to the MVS LOGREC data set might also be useful
