Re: File Reads

Hi Venu,

you could try to use the poolsize of the subsystem your job is running in
and from there do a more specific calculation.
Ev. create a shared pool of a size relative to the  overall memorysize, and
let  your job run in that.

Anyway, you have to take account of the memory that's useable (or not
useable because of other jobs).
