The Real-Time Messaging Framework (RTMF) provides a mechanism for applications to send messages to clients, and to send messages to an RTMF service to initiate a process on the server. This section describes configuration settings for the RTMF.

Procedure

  1. Open the NetWeaver Administrator.

  2. Navigate to   Configuration Management   Infrastructure   Java System Properties  .

  3. In the Details area, select the Services tab.

  4. Select com.sap.netweaver.rtmf.server.

  5. In the Extended Details area, change the settings.

    • PollingIntervalBasis (in seconds): The initial and minimum polling interval. As more clients use RTMF, eventually the PollingMaxHitsPerSecond setting determines the polling interval.

      The default is 3.

    • PollingMaxHitsPerSecond: The maximum number of hits (each poll of the server is a hit) allowed per second on each server node. As more clients use RTMF, more requests are made to the server, so each client must poll the server less. Therefore, the polling interval grows.

      The default is 200. If set to -1, RTMF uses a constant polling interval, determined by the PollingIntervalBasis setting.

    • ClientsUseRTMFHub. Set this value to true if the RTMF hub is used by one or more RTMF clients. Setting this value to true when the RTMF hub is not used on a client machine causes some redundant failed requests to be sent from the client browser (with no affect on RTMF functionality or performance).

      Note Note

      The RTMF hub is a special client installation that does not come out-of-the-box with the NetWeaver server installation.

      End of the note.

    • MaxTotalICMPollingUsers: The number of RTMF-based clients that poll the server through ICM. Polling through ICM improves server performance by reducing the amount of hits made to each server node, and by reusing cached information. In rare instances, a user may experience a delay in receiving messages that were sent one after the other within a short time frame. The available options are:

      • -1 all users poll the server through ICM. This is the default option.

      • 0 all users poll the server directly.

      • <a number greater than 0> the number of users that poll the server through ICM. All remaining users poll the server directly.
