Information in this document applies to any platform.
This document will cover a COMPLETE Refresh only MVIEW. It also should be noted that the only side affect here is with the Optimizer and how this approaches
Query Rewrite. The data in the mview is not affected, other than the fact the Optimizer has no idea how current this is, which is why it has a Status of IMPORT.
Once a COMPLETE Refresh is performed on this mview then all status's go back to FRESH, as per a normal COMPLETE Refresh.
