Configuring Messaging Performance PropertiesLocate this document in the navigation structure

Configure performance properties for messaging-based synchronization in the cluster.


  1. In the left navigation pane, select Configuration.
  2. In the right administration pane, click the General tab.
  3. From the menu bar, select Performance.

    • Maximum number of in memory messages – maximum allowable number of in memory messages.
    • Subscribe bulk load thread pool size – maximum number of threads allocated to initial bulk load subscription operations. The default value is 5. Setting the thread pool size too high can impact performance.
    • Inbound messaging queue count – number of message queues used for incoming messages from the messaging-based synchronization application to the server. SAP recommends you choose a value that represents at least 10% of active devices.
    • Outbound messaging queue count – number of message queues used for outbound messages from the server to the messaging-based synchronization application. SAP recommends a value that represents at least 50% of active devices. However, if you are running 32-bit operating system, do not exceed a value of 100% of active devices.
    • Asynchronous operation replay queue count – the queue limit for asynchronous operation replays. The minimum acceptable queue count is 1 and the default is 5. .
