default execution mode

Whenever I use a DB2 EE stage in a job,I see its default execution mode is sequential and it is also greyed-out so I can't make it parallel.

I thought Db2EE stage read data parallel from Databases but here it seems to be working just opposite.

Anyone knows if this is the nature of EE stage or I am doing something wrong??


Thanks for the help !!

Only from partitioned tables does this stage read in parallel; you need to set the partition table property in the stage.

Nothing. You've asked what I suspect to be an already heavily-loaded system to do more work.
