Answer / ramya
combinality is a mode in Advance tab of a stage.
The mode can have values: Auto, Combinable, Don't Combine.
Auto: let the DataStage decide whether to combine the
stages
Combinable: Combine the operator with other stage if
possible
Don't Combine: do not combine them at all
I think Don't Combine may be non combinability in your
terms.

Answer / sharath s j
Combinability refers to combining operators while running
the job.
EX: Data is read from some table (parallel) Then thru copy
stage u r moving it to another parallel target stage (oracle).
Here the operation of moving thru copy stage will be
combined. When u run the job, you wil not get log entries
for copy stage. And performance stats will not show that the
data is moved to oracle (since copy is combined with oracle)
If you selct "do not combine" in the copy stage, you will
get the logs for copy stage.
