DB2 Universal Database Version 5.2 provides support for dynamically updating certain database configuration parameters, including dft_monswitches (Default Database System Monitor Switches).
The section Monitor Switches Control Data Collected by the Database Manger in the System Monitor Guide and Reference should now indicate that switches can be set without stopping the database management system. These switches can now be dynamically updated, but the application doing the update must be explicitly attached to the instance for the updates to take effect.
| Note: | Any existing snapshot applications will not be affected. In order to pick up the new default values for dft_monswitches, a monitoring application must terminate and reestablish its instance connection. |
