  Oracle Database Tips by Donald Burleson

Analyzing Indexes

For Oracle8, Oracle8i, and Oracle9i, the ANALYZE command can be used to get the average index size from an example index. The format of this command follows. Other statistics are also generated, but these will be covered in Chapter 9.

where:

See Code Depot

       The results appear in the INDEX_STATS  view, and some of the statistics also appear in the *_INDEXES series of views (DBA, USER, and ALL). One thing to remember is that, unlike the DBA_TABLES view, only one row at a time is saved in the INDEX_STATS view, the row for the last index analyzed.
