The in-place refresh executes the refresh statements directly on the materialized view.The out-of-place refresh creates one or more outside tables and executes the refresh statements on the outside tables and then switches the materialized view or affected materialized view partitions with the outside tables.Each materialized view log is associated with a single base table.The materialized view log resides in the same database and schema as its base table.If insufficient temporary space is available to rebuild the indexes, then you must explicitly drop each index or mark it About Types of Refresh for Materialized Views The refresh method can be incremental or a complete refresh.There are two incremental refresh methods, known as log-based refresh and partition change tracking (PCT) refresh. Users can perform a complete refresh at any time after the materialized view is created.The PCT refresh method can be used if the modified base tables are partitioned and the modified base table partitions can be used to identify the affected partitions or portions of data in the materialized view.

In this refresh method, the user does not directly modify the contents of the base tables but must use the APIs provided by the synchronous refresh package that will apply these changes to the base tables and materialized views at the same time to ensure their consistency.For materialized views that use the log-based fast refresh method, a materialized view log and/or a direct loader log keep a record of changes to the base tables.A materialized view log is a schema object that records changes to a base table so that a materialized view defined on the base table can be refreshed incrementally.This chapter discusses how to refresh materialized views, which is a key element in maintaining good performance and consistent data when working with materialized views in a data warehousing environment.This chapter includes the following sections: The database maintains data in materialized views by refreshing them after changes to the base tables.
