SQLAdria Seminar – Opatija 2018 Utilize machine learning to improve your Db2 for z/OS performances

IBM Db2 AI for z/OS empowers the optimizer in your Db2 for z/OS engine to determine the best-performing query access paths based on your workload characteristics. Leveraging machine learning technology, Db2 AI for z/OS collects data from the optimizer and execution history for Db2 for z/OS that are derived from workloads in your unique operating environment. It then finds patterns from this data and learns the optimal access paths for queries entering Db2 for z/OS as part of the model training process. Once trained, the models can be put into production to provide insights that help drive access path selection of the optimizer. Models trained and deployed from Db2 AI for z/OS are managed by the security-rich infrastructure in Machine Learning for z/OS, which also gives defined users a window into the models’ performance metrics.



SQL Adria is the independent, non-profit organization that gathers relational database users for Croatia and Slovenia. It was founded 1994. and in the same year it has become the regional user group.
