How much space a DS job would take on disk?

Hi,

I want to know how much space a DS job (server / PX ) would take on disk?

I understand that the total space would depend on the kind of job / how big / small the job is etc etc, but still I am looking for some general thumrules that could help me to estimate the disk space the job would take.

Cheers

The job design itself won't take more than about 50KB when first designed. The log file will grow indefinitely unless you specify purging, and provided that you resize it to 64-bit addressing before it reaches 2GB. How much scratch space you need depends on how much memory you have and, where possible, how much memory you actually allocated to tasks.

This is almost impossible to quantify as a manual process. Version 8.0 includes a resource estimator, which includes disk space, but IBM has not published its underlying algorithms.
