I would like to know if dropping Oracle index and recreating them will pose any data issues if assuming these are done during scheduled downtime.
Recently discovered that some indexes were parked on incorrect table space, would like to correct it by dropping the index and recreating it on the correct table space.
Please kindly advise.
I don’t see a problem with that, but instead of drop/create you could also use the syntax below:
To address what you asked in the comment below, the
alter index rebuildshould be faster. The reason for that is when you drop the index and create it again, index tree will be built from the table itself. But withalter index rebuild, Oracle reads the index itself, thus resulting in a smaller amount of I/O.
