Agreed. My suggestion is something to do when it really needs done Now and there is no hardware solution in sight.

Splitting the file is a simple step and the next N steps are the original sort cloned N times for each of the split files. Tghe last step should be to merge the smaller split files (and then delete the split files).
Hope this helps,
d.sch.

Hello,

i have an idea but i don't know if it's possible.

I would like to know how dfsort allocate the work dataset (enven if it abend)

VOL SER NOS= VPUB01.
SYS13156.T150720.RA000.DFSORT01.R0130297 DELETED
VOL SER NOS= VPUB01.
SYS13156.T150720.RA000.DFSORT01.R0130298 DELETED
VOL SER NOS= VPUB01.
SYS13156.T150721.RA000.DFSORT01.R0130299 DELETED
VOL SER NOS= VPUB01.
SYS13156.T150722.RA000.DFSORT01.R0130300 DELETED
VOL SER NOS= VPUB01.
SYS13156.T150723.RA000.DFSORT01.R0130301 DELETED




and after i will copy dfsort allocation by including the work dataset in the jcl but the dataset :

SYS13156.T150720.RA000.DFSORT01.R0130298
etc..

are deleted.

Is there a way to keep that dataset in the catalog because i would like ta see their allocation..

It's just an idea, i don't know if it is possible.


About the abend, we have only one volume : VPUB01 for the work dataset. It's a model 9.

I am not sure as to why you want to reinvent the wheel in here. DFSORT allocates SORTWORKS with Primary of zero and then acquires the secondary allocations as when it is needed. You need to talk to your systems programmer as to why you aren't getting the required sortwork allocation.

If you are able to allocate 60 JCL sortworks with UNIT=3390, you can specify that on DYNALLOC too.

Change DYNALLOC=(,60) to DYNALLOC=(3390,60)

It go on to use the disk VPUB01.( VPUB01 is a disk 3390...)

Is there a way to force DFSORT DYNALLOC to use a particular storclass ? I would like to use other disk than VPUB01 by codind DYNALLOC.

How about talking to your systems programmer? You have been working on this issue for about a week now and yet you haven't talked to your systems programmer who in this case is the right person to talk to. There is nothing much we can do.
