Reply with quote

Hi to all.
From few month I'm sorting a file with almost 50 milions of record of a file* that has this feature:
Code:
LRECL=416,RECFM=FB
(and a key of sort of 19 char)
* = is not only one file but are 3 file concatenated

At the moment the sort run, with many SORTWK, in 1 hour(I know that this depend on the hardware of MF) but to reduce this time I'm looking for another solution.

I tested ICETOOL increasing the DYNALLOC option and I've specified the
Code:
OPTION DYNALLOC=(SYSDA,10),FILSZ=E50000000

but the time is not changed.


Thanks in advance both for comment and solution.

I can't really comment on your question without seeing your JCL, control statements, and the DFSORT diagnostic messages which requires adding the following to your job and rerunning it:

//SORTDIAG DD DUMMY

Assuming you're using DFSORT, if you want to send me all that offline (yaeger@us.ibm.com), I'll take a look, but I actually won't have any internet access after today for about 10 days so I won't be able to answer my mail or post here for a while. If you do e-mail me, please put "DFSORT" somewhere in your Subject line to catch my attention.
