DB2 Version 9.7 for Linux, UNIX, and Windows
Use the Activity Monitor to monitor application performance and concurrency, resource consumption, and SQL statement usage of a database or database partition.
The Activity Monitor provides a set of predefined reports based on a specific subset of monitor data. These reports allow you to focus monitoring on application performance, application concurrency, resource consumption, and SQL statement use. The Activity Monitor also provides recommendations for most reports. These recommendations can assist you to diagnose the cause of database performance problems, and to tune queries for optimal utilization of database resources.
