You need to go through the EXPLAIN PLAN part and see what is the cost of the statement with INDEX and without INDEX.

The database maintains all indexes defined against a table regardless of their usage. *Starting in 11.2.0.2, Oracle Database can use function-based indexes to process queries without the function in the where clause. This happens in a special case where the function preserves the leading part of the indexed values. Index usage is categorized into buckets of different ranges.

Hi Jonathan, I wrote before about how to check index usage on the database, in that article I wrote about exploring query plans. However, another reason to check index usage would be to drop indexes not being used. Every index create some level of impact on changes (INSERT/UPDATE/DELETE) and if an index is not being useful, it will be only creating problems. Oracle-DB: Identify unused indexes : A common problem with indexes is: creating an index is quite easy in consideration of the possible impact deleting an index is much more difficult because: Who has the heart to decide this index is really no longer needed? This results in: Nearly every database system stores and maintains indexes that are not really needed.

For example, trunc () … Oracle can use the statistics from the index in determining the best query plan, and when those statistics are gone (as when the index has been dropped) performance can suffer; the optimizer generates a decision tree when each query is hard parsed, and missing index statistics may direct the optimizer down a path it might not have taken when the statistics existed. 2017-07-25 When creating the index, I create the index online and parallel using the following script depending on the number of cpu the system has.

Oracle 12c R2 adds some nice improvements to its index usage tracking feature. With these improvements, it is now easy to find out how many accesses the inde 2010-11-26 · Recent Oracle online course "Understanding Explain Plans & Index Utilization" by Dan Hotka, reminded me to write some thoughts about index and usage in Oracle databases. As we all known, some developers/DBAs have bad habit to "tune" SQL's by adding new indexes with or without real need. An index is used by the Oracle server to speed up retrieval of rows by using a pointer. Indexes are independent of the table it Indexes, both logically and physically.
