I am trying to execute the following sort card with the input files having 120 million records.
JOINKEYS FILES=F1,FIELDS=(1,45,A)
JOINKEYS FILES=F2,FIELDS=(1,45,A)
JOIN UNPAIRED,ONLY,F1
SORT FIELDS=(1,45,CH,A)
My job fails with return code U0016 also i could see the message
WER219I DYNALLOC FAILED RC=(970C) - 3390
WER046A SORT CAPACITY EXCEEDED
Is there anyway to make the sort successful or SYNCSORT itself
unable to handle such volume of records.
anyone please help me. Thanks in advance. |

| As per manual, it seems intermediate storage space is not available. But how do i increase the storage space. I have tried adding JNF1WKnn DD's. |

| One of Syncsort's selling points is their HYPERSORT. Look at that. |

Can you post your JCL ?
WER046A - is because not enough intermediate storage is allocated.
What is the space allocated for sort working files, SORTWKnn ? |

| the volume of records that can be sorted has nothing to do with the sort product---------it is dependent upon your hardware. |

| As a last resort, and many many years ago - I have allocated six TAPE SORTWKnn statements. And that really is a last resort as the elapsed time rises very sharply, but at least it got the job done. |

Clearly you havent used any work files ?
There are many existing topics in this forum which will guide you. |

I have tried using that also.. missed to copy that particular JCL. Irrespective of work files i have used, i am getting SORT CAPACITY EXCEEDED message. Also I could see the message like
| Code: |
912 IGD17272I VOLUME SELECTION HAS FAILED FOR INSUFFICIENT SPACE FOR 708
DATA SET SYS09093.T052920.RA000.JOB1A1WC.R0131395

PROGNAME (SORT ) DDNAME (JNF1WK45)
REQUESTED SPACE QUANTITY = 41501 KB
STORCLAS (SCVIOTST) MGMTCLAS ( ) DATACLAS ( )
STORGRPS (TPUBLIC SGVIO )
912 IKJ56893I FILE JNF1WK45 NOT ALLOCATED+
|
This shows that i dont have enough space in my intermediate volume? |

Hello,
You need to post the complete jcl and sort control statements that you are currently using as well as any diagnostics generated by running that jcl amd sort control info.
Why is the dynalloc parameter used, or is it simply always used on your system?
You may also need to consider using MAXSORT. . . |

Anand B,
Aren't there any examples in the Syncsort documentation showing how to handle large volume sorts? |

Terry,
Unfortunately I dont have any examples in the manual i'm having. If you find anything in online.. please tell me. |

The OP has specifically stated the problem which is the cause of the problem. We know what the problem is.
What is the maximum number of SORTWKnn statements that can be used by SYNCSORT.
HAve you considered using tapes for SORTWKnn - although as a last last resort. |

This shows that i dont have enough space in my intermediate volume? |
How does the above message relate to SORT Capacity exceeded ?
You've allocated 23 SORKWKnn files, each having 1000 cylinders as primary quantity. This space should be enough.
ddname JNF1WK45, where is it used ? |

Hi Anand,
You have asked for more than 2 complete 3390 devices for sortwk. You need to talk with your storage management people to see if there is that much space available in that dataclas or if there is some other you could use for this job.
Something you might consider is sorting the 2 files separately (with MAXSORT if necessary) and then run this process to join. You can tell the join that the files are already in sequence and prevent sorting them as part of the join.

If you cannot allocate the sort work, you run with less and possibly you exceed the sort capacity. . .

Did you calculate this or is it just something you believe. No matter, really, as the space request fails. . . |

When SyncSort is called upon to take care of dynamically allocating the SORTWK space needed, we simply use the system-provided DYNALLOC facility.
In this particular case, the system DYNALLOC facility reported an error. If you have already referred to your IBM documentation, then you know that the 970C Reason Code indicates a "Severe SMS VTOC service error".
Since the system DYNALLOC facility was unable to acquire any more space, SyncSort then ends up failing and posts the message WER046A SORT CAPACITY EXCEEDED.
You can run a SYNCLIST to check the RETRY subparameter of the DYNALOC option. My suspicion is that it may be set to RETRY=(0,0). If this is the case, you may wish to have your system programmer modify it to reflect RETRY=(5,3) or some other value more appropriate for your site. |

Bill,
I think Abin was suggesting that the RETRY subparameter of the DYNALLOC runtime PARM was a better alternative to changing the DYNALOC installation option. Just my guess... |

Yes.. I have not authorized to use that much space.. I have contacted Storage team for a solution. |
