Problems detected in periodic exception processing
If you use periodic exception processing in the Online Monitor and you are notified about a problem, examine the information in the Thread Activity panels or Statistics panels, depending on the type of problem.
- For system related problems, examine the Statistics panel and the DB2® System Parameters panel.
- For application related problems, examine the Thread Activity panels.
To view the past events surrounding the problem online, you can use the HISTORY command. The amount of available historical data is determined by installation-defined options. Note, however, that the batch reports are more comprehensive than the Online Monitor panels. Therefore, if the panels do not provide enough information to solve a problem, the Online Monitor Collect Report Data function should be used to gather information in a data set for input to the batch reports.
