This parameter is unique in that it allows you to set a number of switches which are each internally represented by a bit of the parameter. Depending on the interface you are using to update the database manager configuration, you may be able to update this parameter directly. You may also update each of these switches independently by setting the following parameters:
Changes to any of these database system monitor switches take effect immediately; that is, you do not have to stop and restart the database manager.
| Note: | An existing monitoring application will not automatically use the new default value for a switch. To use the new value (or values), the application must terminate and re-attach to the instance. |
Recommendation: Any switch that is turned ON instructs the database manager to collect monitor data related to that switch. Collecting additional monitor data increases database manager overhead which can impact system performance.
All monitoring applications inherit these default switch settings when the application issues its first monitoring request (for example, setting a switch, activating the event monitor, taking a snapshot). You should turn on a switch in the configuration file only if you want to collect data starting from the moment the database manager is started. (Otherwise, each monitoring application can set its own switches and the data it collects becomes relative to the time its switches are set.)
