What Types of Partitioning Are Eligible for Partition Change Tracking (PCT) Fast Refresh?
Last updated on JULY 28, 2015
Applies to:Oracle Database - Enterprise Edition - Version 10.1.0.2 to 220.127.116.11 [Release 10.1 to 12.1]
Information in this document applies to any platform.
When there have been partition maintenance operations on the detail tables for a materialized view, Partition Change Tracking (PCT) is the only method of fast refresh that can be used. The partitioning of the materialized view itself has no bearing on this feature.
If PCT refresh is possible, it will occur automatically and no user intervention is required in order for it to occur. However, only certain types of partitioned tables are eligible for PCT. The Oracle Datawarehousing Guide documentation (though version 11.2) does not currently contain the information about this restriction. This note documents which types of partitioned tables are eligible for PCT.
