Hi Frank/List,
My client has some very big SORT jobs.
When a few run at the the same time, the page DS USE% increases
(demanding paging).
Q1-
How do I make sure BIG sort jobs don't use too many frames,
when they are hard to get?
Q2-
Given the sort options we use, is it true that
SORT will use TMAXLIM size of storage,
then if data is too big, it will increase the storage use to max of DSA
size?
So it never goes over DSA size?
Q3-
If I get
ICE199I 0 MEMORY OBJECT STORAGE USED = 3463M BYTES
it means 3.4GB of data was sorted in memory, right?
Q4-
If YES to both Q2/Q3, then how is 3GB of data is sorted in 64M of memory
(our DSA)
If, not, how does it work?
Q5-
We use SIZE=MAX, but the job has SIZE=32259547 (it can be different for
another run).
Is this because the size of data being sorted determines the actual SIZE
used?
TIA,
Rez
