Abstract
A cache manager of a relational database management system (RDBMS) is able to bypass time consuming search operations through the use of a key memory structure and locate generated code segments within an SQL cache within a minimum of time. The SQL cache contains the generated code segments used to execute SQL statements as well as the structures and program logic used for maintaining the cache. The key memory structure is located in an area of memory utilized by the SQL runtime routines in executing applications. The runtime routines provide an interface between the application and the RDBMS.
