Force a refresh
Fast - uses the changes in the view log on the source side.
6@@
Complete - truncates or deletes the data (depending on other options) and rebuilds the view from scratch (remember to gather view stats afterwards).
7@@
Force - tries a fast. If this does not work, a complete will be done.
8@@
Rebuild a broken View
Sometimes the materialised views stop working. If the original table was modified for example (maybe index was changed or a column removed), the view will fail.
