Materialized view create statement taking too much time

edited May 22, 2013 3:43AM in Database DataWarehousing (MOSC) 9 commentsAnswered
Hi Gurus,
We have two tables of 100 GB and 12 GB respectively on our Production 2 node RAC(11.2.0.3). Both these tables are similar in their column structure. We are trying to create fast refresh materialized view on another DB using DB link on both these tables for replication. Both tables have materialized view logs created. Creating mview on 100 GB took only 7 minutes where as mview creation on smaller table of 12 GB takes over 8-9 hours. This is weird oracle behaviour considering both mview statements are identical for both.

Any help is welcome and much appreciated.
