The P4ConnectionTest reports the availability and response time of the P4 connection to the SAP Web AS. This page depicts the default parameters that need to be configured for the P4ConnectionTest.

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

• This test connects to a specific SAP web application server instance, and extracts critical metrics from it. Therefore, in the USERNAME text box, provide a valid user name which the test should use for connecting to the server instance.

• Provide the PASSWORD that corresponds to the specified USERNAME.

• Confirm the password by retyping it in the CONFIRM PASSWORD box.

• In the INSTANCENAME text box, provide the application server instance to which the test should connect. For example, if you specify tpp here, then the test will use the login credentials (USERNAME and PASSWORD) provided here to connect to an instance named TPP, which is incidentally the central instance of the SAP web application server. To know the available server instances, use the Programs -> SAP Management Console menu sequence on the application server host, and open the SAP Management Console. In the tree-structure in the left pane of the console, you will find a SAP Systems node. When you expand the SAP Systems node, the available server instances will appear as its sub-nodes. Any one of the displayed instance names can be specified in the INSTANCENAME text box.

• This test uses the P4 protocol for connecting to the SAP web application server. Therefore, the port at which the P4 protocol listens needs to be specified as the CONNECTORPORT. The default port number of the P4 protocol is 50004. However, if the P4 protocol listens at a different port in your environment, then specify the exact port number here. To know the P4 protocol port, first open the adminCFG.properties file in the {SAP_WAS_HOME_DIR}\usr\sap\TPP\DVEBMGS00\j2ee\admin\classes directory. The value specified against the LOGIN_PORT parameter in that file, is the P4 protocol port.

• Once the necessary values have been entered, clicking on the UPDATE button will register the changes made.

When changing default configurations of tests, the values with "$" indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to "xyz" and $port will be changed to "80" when configuring a test.
