What precisely is parallelised when running a fast refresh job in parallel

edited Feb 14, 2012 10:50PM in Database DataWarehousing (MOSC) 5 commentsAnswered
Hi - my customer wants to speed up his fast refresh jobs (one in particular) and is considering changing the job to run in parallel (by setting the 'parallel' parameter in the'dbms_refresh.change' procedure, then running that procedure. If this is done, what exactly is run in parallel  -  MLOG scans, db links, selects, inserts or just concurrent execution of group members? Any thoughts would be appreciated. This is Oracle version 11.1.0.7, incidentally.

Howdy, Stranger!
