 * Identify Performance Bottlenecks: Discover powerful tools and techniques to pinpoint the root causes of query slowdowns.
 * Leverage Explain Plans: Understand the execution plan of your queries to identify inefficiencies and opportunities for optimization.
 * Optimize Query Structure: Learn how to rewrite queries to improve their performance, including techniques like indexing, partitioning, and query hints.
 * Utilize DB2 Performance Tools: Explore the suite of DB2 performance monitoring and tuning tools to gain valuable insights into your database behavior.
 * Implement Effective Monitoring Strategies: Establish a robust monitoring framework to proactively identify and address performance issues.
By attending this session, you'll gain the skills and knowledge to significantly improve the performance of your DB2 queries, leading to faster response times, reduced system load, and enhanced overall database efficiency.

IBM Db2 Query Monitor for z/OS, V3.4 offers current and historical views of query activity throughout Db2 subsystems. It gives you the ability to efficiently customize and tune your SQL workload and Db2 objects to validate the effectiveness of your Db2 subsystems and improve overall performance. It also offers you extensive choices so you can determine what monitoring information you will gather, and when.
DB2 Query Monitor for z/OS enables you to identify problem SQL activity and applications, allowing you to focus your efforts on improvement. DB2 Query Monitor enables you to do the following:  – Proactively manage DB2 resources  – React quickly and effectively to supply and demand–related DB2 problems (such as those resulting from inefficient SQL or inadequate object structures)  – Identify SQL requests that prevent critical requests from completing on schedule
Db2 Query Monitor comes with two interfaces, ISPF and a Web Client.  This hands on lab will take the user through the Web Client interface.   From your web browser, you can review query activity in Db2 Query Monitor, the SQL/CA, Db2 Commands, view alerts, and configure actions and responses.
