iam using the below jcl to search the copybook in the cobol program PDs
//LLLLLLLM JOB (YYYYYYY),'SCAN',CLASS=V,MSGCLASS=W,
// NOTIFY=LLLLLLL
//SEARCH EXEC PGM=ISRSUPC,
// PARM=(SRCHCMP,
// 'ANYC MIXED')
//NEWDD DD DSN=XXXXXXX.A.B,DISP=SHR
// DD DSN=XXXXXXX.D.E.DISP=SHR
// DD DSN=ZZZZZZZ.X.Y,DISP=SHR
//OUTDD DD SYSOUT=(A)
//SYSIN DD *
SRCHFOR 'F210CU',W
/* ----------------------------------------------------------------------------
and this step is returing the results fast and not taking mcuh cpu time
but after this step i have coded a sort step in which it will take output file of above step and retrieve only the cobol program name
in that step iam executing SORT program and in include condition i gave
sort options = COPY
Include COND = (position ,EQ,c'string (s) found match line')
ourec fileds=(1:copybook name position)
this step returning the exact results but it is taking lotzzzz of CPU time please llet me know if i can use any other utility which does the performance tuning.
how abt using ICETOOL
and also i wanted to check that user enetered copybook is valid or not by chking in copybook library any idea regarding the same pls suggest.
Thanks & Regarding,
Sandhya Rani. |

| How much CPU time is consumed, how much elapsed time is used. |

is this a syncsort question?
why don't you use INREC? |

Why didn't you post also step 2, the only one that we really need to see??
Also, in the SEARCH step, the result is written to SYSOUT=(A).
How can it be input to the SORT??
Consider using the following options in your search (instead of just ANYC MIXED).
They will make the whole process (search and sort) faster: COBOL, DPBLKCL, DPCBCMT, FMSTOP, NOSUMS, LMTO, NOPRTCC |

and this ICETOOL also consuming more CPU time

please suggest me if i can do something to get the fast results |

Hello Sandhya Rani,
If you are running SyncSort for z/OS, please feel free to email me offline with the complete job listing as a text attachment and I would be happy to further assist you. You can contact me at [email protected]. |

Hello,
Each step shows amount of cpu used - it will help if you post all of these statistics for each step of both runs.
How many records are being processed?
Where did the term "unnormalized cpu time" originate? |

Sandhya,
I have not yet received any email from you. If you sent it to me directly at [email protected], please forward a copy to [email protected] to see if that can get through. |

I am not sure if this could be a reason for the performance difference. But the same output ddname - OUTPUT is used for both the 'COPY' statements used above with a DISP=(NEW,CATLG,DELETE). Wont the 2nd 'COPY' overwrite the results of first 'COPY' thereby missing some search strings passed into the subsequent step?
Before going into performance, are you getting the same results from both the runs? |

Could you let me know how you have come up with this stats.
What does Unnormlized CPU time mean in your context? |
