How to identify unused indexes in DB2 for Linux, UNIX, and Windows
During database application development, developers tend to define a large number of
indexes on tables to guarantee that each and every query performs well.
After application development has been
finished and a database has gone into production, the existence of too many indexes turns
out to be a cause for decreased
database performance.
Many indexes mean more work for the database system when executing UPDATE, INSERT, and
DELETE (UID) operations.
In addition, regular maintenance activities like RUNSTATS and REORG also run
considerably longer in cases where many indexes are present.
Therefore, to achieve the best database performance, it is
critical to be able to determine which indexes are necessary for query execution and which
indexes you can
safely drop without impacting query runtimes.
This article explains several methods that a DB2 for Linux, UNIX, and Windows (DB2 LUW) database
administrator (DBA) can use to identify unused and seldom used indexes.
