Example: Using the AsapSource ComponentLocate this document in the navigation structure

Associate the AsapSource (reader) component with the FileSink (writer) component. AsapSource reads records from Event Stream Processor and passes those to FileSink, which then writes those records to the out.txt file.

Prerequisites

The cluster database stores configuration information. Ensure that the cluster is running, so that the adapter can interact with the projects on the cluster.

Procedure

  1. Set the user name and password in the example environment:
    Operating System Step
    Windows
    1. Edit the set_example_env.bat script
    2. Set the ADAPTER_EXAMPLE_USERNAME and ADAPTER_EXAMPLE_PASSWORD variables to the desired user name/password combination.
    3. If SSL is enabled, set ADAPTER_EXAMPLE_CLUSTER_NODE_PROTOCOL to esps. If it is disabled, set it to esp.
    UNIX
    1. Edit the set_example_env.sh script
    2. Set the ADAPTER_EXAMPLE_USERNAME and ADAPTER_EXAMPLE_PASSWORD variables to the desired user name/password combination.
    3. If SSL is enabled, set ADAPTER_EXAMPLE_CLUSTER_NODE_PROTOCOL to esps. If it is disabled, set it to esp.
  2. Start SAP Event Stream Processor.
    Operating System Step
    Windows Open a command window:
    1. Start the cluster:

      start_server_cluster.bat

    2. Add project to the cluster, and start it on the cluster:

      start_project.bat
    UNIX Open a terminal window:
    1. Start the cluster:

      ./start_server_cluster.sh

    2. Start the project on the cluster:

      ./start_project.sh
  3. Start streamingsubscribe to subscribe to the project that is running on the cluster.
    Operating System Step
    Windows Open a command window and enter:

    streamingsubscribe.bat
    UNIX Open a terminal window and enter:

    ./streamingsubscribe.sh
  4. Starts the AsapSource and FileSink components.
    Operating System Step
    UNIX Open a terminal window and enter:

    ./asapToFile.sh
    Windows Open a command window and enter:

    asapToFile.bat
  5. Upload data from the esp_insert.txt file to the Server.
    Operating System Step
    UNIX Open a terminal window and enter:

    ./streamingupload.sh
    Windows Open a command window and enter:

    streamingupload.bat
    AsapSource reads this published data from the Server and passes it to FileSink, which writes it to the out.txt file.
