DB2 for z/OS Application Performance and Tuning

( Duration: 5 Days )

The DB2 for z/OS Application Performance and Tuning training course is designed to teach you how to prevent application performance problems and to improve the performance of existing applications. You will learn about indexes, table design, locking, and other issues relevant to application performance.

By attending DB2 for z/OS Application Performance and Tuning workshop, delegates will learn to:

  • Design better indexes
  • Determine how to live with the optimizer (avoid pitfalls, help when necessary)
  • Avoid locking problems
  • Use accounting trace information to find significant performance problems in an operational application

  • Familiarity with DB2 for z/OS application programming and SQL.

This DB2 for z/OS Application Performance and Tuning class is designed for DB2 for z/OS application developers, DB2 for z/OS DBAs
