CDC Internal Functionality

Post by snt_ds »

Hi,

Can someone pls explain the internal algorithm or logic that Datastage CDC stage uses to compare the Before & After Dataset?

Does it take the 2 sets of data in memory (per partition) and do a one to one row comparision..or some other way.

Is there any architecture diagram or doc for this available anywhere?

Have you taken a look at the Operators reference pdf for the changecapture Operator?

That is, the Orchestrate Operators manual. It doesn't ship with DataStage but can be had for the asking from the vendor (ask for the OEM 75 Manuals) or is handed out on pretty much every IBM DataStage class.
