COLMAP - None Of The Mapped Columns Are Updated, Colmap where no incoming data is in a mapped column (Doc ID 1536221.1)

Last updated on FEBRUARY 03, 2017

Applies to:

Oracle GoldenGate - Version and later
Information in this document applies to any platform.



When mapping a production table to a target table, we only want to map a subset of the columns. Colmap is in use but some of the rows being updated have no columns that match the colmap.

The question is how does GoldenGate handle an UPDATE where the only column updated is NOT in the COLMAP clause and  USEDEFAULTS is not specified.


 updates are to columns that are not mapping / replicating
