DB2 Performance and Tuning for UNIX and Windows
Course: DB2PTUW
Duration: 3 Days
Level: II
Course Summary
This course is designed to review many aspects of performance and tuning of DB2 version 9.7, for Linux, UNIX and Windows (LUW). DB2 commands and tools created by IBM for DB2, will be used to support workshop activities. Performance and tuning varies with type of user to be supported. We will review this topic for support of SQL users, programmers, data designers and database administrators.
