Hi All,

I have used the below job to get the elapsed time of a transaction which has program-a calling program B, also linking program C, where program-A is CICS-COB-DB2 program and program B is COB and program C is also CICS-COB. I have used 'SHORT' in the control card which

Code:


//TESTPF1B JOB(ESTA),'NB02020',MSGCLASS=0,MSGLEVEL=(1,1),CLASS=U,
//                  NOTIFY=&SYSUID
// EXEC PGM=DFHTU690                                             
//STEPLIB DD DISP=SHR,DSN=SYS3.CICS.X690.UI30599.SDFHLOAD         
//DFHAUXT  DD DISP=SHR,DSN=SYSC.CICS.XA2.X690.DFHAUXT             
//DFHAXPRT DD SYSOUT=A                                           
//DFHAXPRM DD * ...                                               
SHORT                                                             
/*     


gives the CICS TRACE of whole dump, how i can identify the program-a,program-b,program-c elapsed time? please help.

Talk to your CICS people. Remember you've lengthened the elapsed time by tracing it.

Usual way to do this is to fill the screen in, press Enter/start stopwatch simultaneously and then stop stopwatch when screen "returns". Record.

Remember, one isolated example needn't tell you the full picture anyway. What are you trying to do?

Hi Bill,

As you have mentioned, it would be unsure which program is taking long time to execute in case of my scenario where program-a is calling program-b and program-c is liked from program-a. also program-a is having db2 SQL calls. To get the precised picture of which program is consuming how much time, i have tried this option.

Code:

1CICS - AUXILIARY TRACE FROM 21/07/16 - APPLID PVCICA2                 
                                                                       
0SELECTIVE TRACE PRINT PARAMETERS:                                     
                                                                       
 SHORT                                                                 
                                                                       
1CICS - AUXILIARY TRACE FROM 21/07/16 - APPLID PVCICA2                 
                                                                       
 37855 QR    AP 00E1 EIP   EXIT  SET-TRACEDEST OK                     REQ(00F4) FIELD-A(00000000 ....) FIELD-B(00007804 ....)
                                 BOUNDARY(0200)                              RET-AAD9336A 18:52:25.6191296474 **.********** =000001=

       


I got the below output structure.

Talk to CICS admin ask for what you need or explore if you have any tool like OMEGAMON or CA-Insight. or check SQL if its using or not all the desired Indexes (quickest way to find the culprit)
