SQL Optimizer for DB2 LUW 4.4.1

The Index Usage Analyzer identifies the usage of the indexes in your database application by uncovering both the indexes that are being used and the indexes that are not being unused. It analyzes the access plans from SQL statements in the SQL statements that are save in the SQL Repository. You can use this module to quickly identify the indexes in databases that are not contributing to the performance of the database applications. These unused indexes can then be deleted to free up space and improve the speed of the database applications and maintenance.
