I want to sort one file which is on tape, with a record length of 5700. This file is having nearly 30 million records. I've used the below jcl.
| Code: |
//PS010 EXEC PGM=SYNCSORT,PARM='MAXSORT,MINWSP=600,DYNATAPE'
//SYSOUT DD SYSOUT=*
//SORTIN DD DSN=xxx.XUNLD.TST.CNTLREC.JUL23,DISP=SHR
//SORTOUT DD DSN=yyyy.ALLPERS.ASCNDNG.OUTPUT.JUL23P2,
// DISP=(,CATLG,DELETE),
// UNIT=(CART36,,DEFER),
// LABEL=EXPDT=99000,VOL=(,,,99),
// DCB=(B0.DSCB)
//SORTWK01 DD SPACE=(CYL,(700,700),RLSE),UNIT=WORK
like this i gave 20 work files.
|
i want to sort the input file based on some key condition.
Error which i got in sysout is
SYSIN :
SORT FIELDS=(27,22,CH,A)
WER131I PARM FIELD ERROR - MINWSP=6
WER164B 21,716K BYTES OF VIRTUAL STORAGE AVAILABLE, MAX REQUESTED,
WER164B 0 BYTES RESERVE REQUESTED, 2M BYTES USED
WER317I MAXSORT OPTION SELECTED
WER300A SORTBKPT DD STATEMENT REQUIRED |

Hi,
In MAXSORT there is no PARM like MINWSP.
Only MINWKSP exists.
| Code: |
MINWKSP:
This option specifies the minimum amount of disk SORTWK space that MAXSORT can
use. If the MINWKSP value exceeds the primary allocation and sufficient secondary allocation
cannot be obtained to meet the MINWKSP value at the time of execution, the sort terminates.
It can be restarted later when more space is available.
The MINWKSP value may be specified as a decimal number of cylinders (n) or a decimal
number of megabytes (nM) of work space.
The default MINWKSP value is 500 cylinders.
If MINWKSP is specified as n cylinders, MAXSORT will convert the specification to an
actual byte value. MAXSORT will multiply by n the capacity of a cylinder on the disk allocated
to the lowest-numbered SORTWKnn DD statement.
Note: MINWKSP should be specified as less than or equal to MAXWKSP, if specified.

Hello,
I suspect that not all 5700 bytes of all 30million records is needed in this new sequence.
If you do a bit of work and reduce the volume of data to be sorted by both limiting the set of records and/or the fields selected from them, your sort will be much more easily accommodated by the system. |

Trying to read your post without code bbtags is a pain. what was somewhat obvious:

either you need this, or you have entered somuch crap in your control cards that syncsort thinks it needs this dd statement.
Have you even bothered to read about syncsorts' hypersort?
That is a major selling point to this product.
I can not believe that you need 20 sortwk statements for this. Alissa will be along in a while and save your butt.
I would suggest doing some reading about the product.
Can't believe there is not something inhouse for a large sort.
And learn to use bbcode: ibmmainframes.com/faq.php?mode=bbcode |

Hi !
Normaly, you don't have to bother about SortWorkAreas, because of the
DynamicAllocation of these Areas, if Syncsort is propper installed.
Plse read more about the following in the SortDocumentation. These Parameters will give more space to Sort when sorting huge files.
//STEP50 EXEC PGM=SORT
//SYSOUT DD SYSOUT=*
//*
//$ORTPARM DD DSN=J120830.PARMKA.SORTOSP7(SORTPARM),
// DISP=SHR
Content of SORTPARM:
VSCORE=5M
VSCORET=30M |

Or it may also helpful if you provide any link related to this..

Hi,
UmeySan did provide you with an example.
The $ORTPARM DD is the statement to be added to your JCL and VSCORE=5M and VSCORET=30M are the parameters needed
| Code: |
//$ORTPARM DD *
VSCORE=5M
VSCORET=30M
