Reply with quote

Hi,

Actually my problem is that in my job the input dataset is having varying number of records.Sometimes it comes to 100,sometimes 10000,means its varying.But the problem is when I am specifying the space parameters it will abend as I am not sure about the number of records.
So,Is there any way to optimize this like depending upon the number of records it will allocate space(apart from RLSE parameter).

Thanks and Regards
Sandeep.

Any specific reason for not using the RLSE parameter?

I think there is no other perameter which will control the space of an input dataset other than SPACE perameter.

Hello,

In your jcl, specify an "average" size for the primary allocation and specify a larger secondary allocation. Do use the RLSE parameter.

What business reason could there be to avoid RLSE?
