execution mode for Oracle Enterprise stage
Posted: Wed Aug 17, 2011 4:29 am
Hi All, I am reading from Oracle Enterprise stage and writing to dataset stage. My question is related to execution mode of the stage. Here i am trying to explain my job design. I have 2 different flows in the same pallet reading from 2 different table
Oracle --> Transformer stage --> Dataset satge (flow 1)
Oracle --> Copy stage --> Dataset satge (flow 2)
Flow 1
It is fetching around 40 million record and the source table is a partition table and the speed is 55000 per sec
Flow 2
It is fetching around 20 million record and the source table is a non-partition table and the speed is 18000 per sec
when i check the oracle stage property, the executation mode is parallel for flow 1 and execuation mode is sequential for flow 2
Now my question is is the mode of execution depends on table partition. Because as i have explain before the number of rows per sec from the first flow is more than second flow.
Appreciate Any help
