The DDCMasterTest periodically verifies whether configured ports on the DDC are available or not, and if so how quickly it responds to connection requests. This page appears by clicking the Configure / Component button corresponding to the DDCMasterTest in the AGENTS - TESTS CONFIGURATION page. Here, the discovered servers that need to be configured for this test are available in the COMPONENTS WITH DEFAULT CONFIGURATION section. Select the required server from this box and click the Configure button at the bottom to configure the parameters pertaining to this test. The default parameters associated with this will be displayed at the bottom of this page.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• In the HOST text box, the host name of the server for which the test is to be configured has to be specified.

• In the PORT text box, enter the port at which the specified HOST listens. The default port is 80.

• In the TARGETPORTS text box, specify either a comma-separated list of port numbers that are to be tested (eg., 80,7077,1521), or a comma-separated list of port name:port number pairs that are to be tested (eg., smtp:25,mssql:1433). In the latter case, the port name will be displayed in the monitor interface. Alternatively, this parameter can take a comma-separated list of port name:IP address:port number pairs that are to be tested, so as to enable the test to try and connect to Tcp ports on multiple IP addresses. For example, mysql:192.168.0.102:1433,egwebsite:209.15.165.127:80.

• If the ISPASSIVE flag is set to Yes, then the server under consideration is a passive server in an Oracle cluster. No alerts will be generated if the server is not running. Measures will be reported as "Not applicable' by the agent if the server is not up.

• Specify the duration (in seconds) in the TIMEOUT text box beyond which the this test will time out if a response is not received from the DDC. The default is 60 seconds.

• If multiple components of the same component type are awaiting configuration, then an APPLY TO OTHER COMPONENTS check box will appear in this page. Clicking on this check box will allow you to apply the configuration to all/selected components of that type.

• Once the necessary values have been provided, clicking on the Update button will register the changes made and the selected server will move over to the CONFIGURED COMPONENTS panel.

• The test parameters for an already configured server can be reconfigured using the Reconfigure button. The parameter configuration page reappears and the required changes can be made to the existing values of the parameters.

• If the test under consideration is not to be executed for any of the configured servers, they can be removed from the list using the Exclude button doing which will move the server to the EXCLUDED COMPONENTS panel.

• Clicking on the Include button in this panel will add the excluded server to the list of servers to be configured.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of "none" in the parameter value indicates that the corresponding parameter value can be changed if required.
