Oracle MView logs

edited Jan 14, 2010 1:29AM in Database DataWarehousing (MOSC) 3 commentsAnswered
Hi,

I am created mviews on our warehouse, which would do the fast refresh from our production DB.

In order to do the REFRESH FAST ON DEMAND (nightly) I need to create MView logs on the source (production) tables

My questions ,

How will the Mview logs effect the production performance? Since it has now to write to one more location, what is the impact on prod tables.

Which process is responsible for writing to Mview logs, archiver or LGWR or SMON?

Thanks

Howdy, Stranger!
