I have an input file with approx 8 million records and I need to sort it using SYNCSORT and create a temporary output file. However I dont have enough space in DASD for the temporary dataset - do I need to chop my input file into smaller files or is there any way round the space problem?

Fin,

What exactly are you trying to do ? Are you sorting the file and feeding it into another program ?

You can increase the space allocation on a temporary just like any regular dataset.

I am afraid the job will abend due to system space limitations in DASD....I do not have facility to test with such a large input data set in my area so I have to let it go to a production system to find out..anyway I will give it a try and see how it goes.
Thanks for the advice.

Fin,

Did u try to store the dataset in COMPRESSED volume ? If u have problem allocating huge space as a bulk, you can probably try to split the output file in chunks of 3-5 files using OUTFIL option of SORT. Say 1.2 million records in each file (first 1.2 million in file 1, 2nd 1.2 million in file 2 and so on).

Thanks,
Phantom
