In two ways we see the CICS error logs:

• Batch
• Online-CEMT and CSMT

You can run a batch job, such as DFHJUP, to read and process CICS log data in MVS system logger log streams and in MVS SMF data sets.

The following Batch job will be run on each LPAR to route error messages to TSO:

//PRNTJNL EXEC PGM=DFHJUP
//STEPLIB  DD DSN=CICSTS23.CICS.SDFHLOAD,DISP=SHR
//SYSPRINT DD SYSOUT=*
//STEP1    DD DSN=IXGLOGR.ATR.ADCDPL.MAIN.UR.A0000000,
//         DCB=BLKSIZE=32760,
//         SUBSYS=(LOGR,DFHLGCNV,
// ‘FROM=(2005/001,00:00),TO=(2005/160,23:50),LOCAL’)
//SYSIN    DD  *
  OPTION PRINT
END

The other way is:

CEMT INQ JOU . “JOU’ is the name of the journal.

Also, CSMT we can see the error logs:
