When this type of monitoring is configured, Directory Proxy Server establishes a dedicated connection to a data source when no requests made to the data source or responses given by the data source for a specified time period. By periodically establishing a dedicated connection to a data source, Directory Proxy Server monitors whether the data source is working.
This type of monitoring is more complete than Monitoring a Data Source by Listening for Errors because Directory Proxy Server does not wait to detect a failure before it tests the data source. However, this type of monitoring is less complete than Monitoring Data Sources by Testing Established Connections, because the proxy does not test whether the existing connections to a data source are working.
This type of monitoring can be used in addition to Monitoring Data Sources by Testing Established Connections.
