Db2 for z/OS Database Performance Tuning


Duration: 3 Days

Method: Instructor led, Hands-on workshops

Price: $1920.00

Course Code: DB3052


Db2 Database and System Administrators who will be monitoring and tuning Db2 for z/OS Databases.


Meeting performance objectives is a key priority for the Db2 database and systems administrators. Db2 for z/OS database performance is best achieved by first establishing performance requirements and planning for performance monitoring. Our workshops assist in identifying critical performance bottlenecks, implementing performance tuning techniques and reviewing tuning results. We provide detailed guidance information for all personnel who will be participating in database performance in both a data sharing and non-data sharing environment.


Upon successful completion of this course, the student will be able to:

  • Develop a Performance Monitoring Strategy
  • Reduce overall CPU consumption
  • Reduce overall lock contention problems
  • Improve overall application response times
  • Identify and tune I/O overhead
