pp108 : Invoking the operations of a Managed Component

Invoking the operations of a Managed Component
This topic describes the procedure to invoke the operations of WS-Apps Service Container.

Let us consider that there is a need for the administrator to invoke the operations of a Managed Component of Process Platform. The following steps describe the procedure to invoke the operations of Ws-Apps Service container to find the memory leak. The following two operations of Service Container are used to identify the memory leaks in java code.

  • setNOMLeakInfoBaseline is used to set a baseline for the number of existing NOM nodes.
  • getNOMLeakInfo is used to retrieve the information related to the leaking NOM nodes since the last baseline.

    Note: The operation resetCounter is used to reset the counters with the default values

    Pre-requisites:

    1. Create Ws-Apps Service container.
    2. Generate Web Services on Database.

  1. After connecting to JConsole using the JMX Address URL of the Ws-Apps Service Container , click the operations node under the Ws-Apps Service Container.
  2. Select and invoke 'setNOMLeakInfoBaseline' operation as shown in the following figure.
  3. Select and invoke 'getNOMLeakInfo' operation without executing any Web Service. In this case, the response is empty under 'GrowingDocuments' node as there is no memory leak.
  4. Run the web services specific to WS-Apps Service Container using Service Test Tool and also load or reload the database.
  5. Invoke the Operation 'getNOMLeakInfo'. If there is a memory leak, you can see the stack trace of the memory leak under the GrowingDocuments node.
