Issue/Introduction

The Values in the Trans column on CSYSDATA online view are different than the number of transactions reported by the XPFRMAIN batch report from the same Sysview SMF logstream data.

For example:

SYSVIEW ISPF1 XXXX  CSYSDATA, CICS System Interval Summary

Running the following XPFRMAIN batch report:

//jobcard

END                                                              
RUN                                                              
/*                                                               
//

The output shows this record:

 DATE    TIME   JOBNAME    TRANVOL 
-------- -----  --------   --------
06/14/22 11.00  CICSTST1        8

In the Trans column of CSYSDATA the value is 9 but in the Batch report the value in the TRANVOL is 8. Why there is this difference?

Environment

Release : 16.0

Component : SYSVIEW

Cause

The Trans column in the CSYSDATA displays the number of transactions monitored for the interval. When you run the report, the variable for the transactions monitored for the interval is not  CICS_TransCnt but CICS_TranGSVI

Resolution

Run the report using CICS_TranGSVI instead of CICS_TransCnt

Replace the line:

CICS INTERVAL SYSTEM CICS_TRANSCNT    HDR1( ) HDR2(TRANVOL)   

By

CICS INTERVAL SYSTEM CICS_TranGSVI    HDR1( ) HDR2(TRANVOL)
