Hi Venkata,
| Code: | //STEP1OF1 EXEC PGM=IEBGENER
//STATOUT DD SYSOUT=*
//SYSPRINT DD SYSOUT=* <--- LRECL=121 --->
//SYSUDUMP DD SYSOUT=*
//SYSOUD DD SYSOUT=*
//SYSOUT DD SYSOUT=*
//SYSIN DD DUMMY
//SYSUT1 DD DISP=SHR,DSN=<--- SOURCE -->
//SYSUT2 DD DSN=<---DESTINATION DATASET--->,
// DISP=(NEW,CATLG,DELETE),
// UNIT=(SYSDA,3),
// SPACE=(TRK,(15,30),RLSE),
// DCB=*.SYSUT1 <--- DCB CHARACTERISCS OF INPUT |
Hope this helps. |

Do not code the DCB=*.SYSUT1 parameter, but instead code the RECFM and LRECL of the dataset.
By using the BLKSIZE of the tape dataset you could waste a hell of a lot of DASD space by bad blocking. |

Actullay i am using the same jcl but i am getting a space abend SD37
I increased the space & tried to run but still i am getting the same.
Currently i allocated space in cylenders primary - 100 & secondary - 150 but still i am getting same abend.
So i thought like any other utilities will be helpful for copying huge file

Hi Venkata,
Please try using the below code either. It's just a SORT!
| Code: | //STEP010 EXEC PGM=SYNCSORT,REGION=4096K
//SORTIN DD DSN=Input disk file,
// DISP=SHR
//* LABEL IS USED TO RETAIN THE DATASET FOR LONG. ESPECIALLY 99000
//* IS GIVEN WHEN YOU WANT THE FILE ON TAPE TO BE NOT DELETED EVER
//SORTOUT DD DSN=Output file name2,
// UNIT=TAPE,VOL=(,,,99),LABEL=EXPDT=99000,
// DCB=(SYS1.DSCB,RECFM=FS,DSORG=PS)
//SYSOUT DD SYSOUT=*
//SYSPRINT DD SYSOUT=*
//SYSUDUMP DD SYSOUT=*
//SYSIN DD *
SORT FIELDS=COPY
//* |

Bharath.AK,
The poster is trying to copy a TAPE dataset to DASD and you show a JCL creating another Tape dataset.
And what is the point of coding SYS1.DCSB in DCb parm? You are creating a spanned record with the JCL. Please understand the question and post the solutions accordingly.

jajularamesh,
There must be a valid reason for the input file to be on tape. It might be huge and hence it is on tape. And looking the errors I can say that it is indeed huge. Why not copy a subset of the input file like first 1000 records . use the following JCL
| Code: |
//STEP0100 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//SORTIN DD DSN=Input tape file,
// DISP=SHR
//SORTOUT DD DSN=Output file name2,
// DISP=(NEW,CATLG,DELETE),
// UNIT=SYSDA,
// SPACE=(CYL,(30,15),RLSE)
//SYSIN DD *
SORT FIELDS=COPY
OPTION STOPAFT=1000

jajularamesh,
you may want to know what is on the tape. here is a link with a couple of ideas how to generate a 'map' of the tape. Then you would know what DASD resources you require.

In this example for fixed length records, the "RECFM=FS" means standard, not spanned. Only full blocks are written (no truncated blocks), with the exception of the last block!
Spanned records are only a variable length concept.

Bill Dennis,
Thanks Bill for clarifying the "Standard" vs "Spanned" concept
