Create Materialized View Group: Overview

Materialized View Groups are located at remote materialized view sites and are based on a single, target master site.

Before you create your materialized view group, be sure that you have set up the materialized view site to support replication (see Setting Up Materialized View Sites for details). Also, create the materialized view logs for the target master tables prior to creating the materialized view group. A materialized view log is required for materialized views to perform fast refreshes with the master table. See Creating Materialized View Logs for instructions.
