Example: Using File Connectors

Use file connectors to read Quote messages from a file, and publish them to the Event Stream Processor. If the value of the OfferPx field is less than 30.0, write a NewOrderSingle message to another file.

1. Start Event Stream Processor.

   Operating System	Step
   UNIX	Open a terminal window: Start the example cluster: start_node.sh Start the project on the cluster: start_project.sh
   Windows	Open a command window: Start the example cluster: start_node.bat Add project to the cluster, and start it on the cluster: start_project.bat

2. Start the respective subscriber utility for Event Stream Processor.

   Operating System	Step
   UNIX	Open a terminal window and enter: ./esp-subscribe.sh
   Windows	Open a command window and enter: esp-subscribe.bat

3. Start the adapter.

   Operating System	Step
   UNIX	Open a terminal window and enter: start_adapter.sh
   Windows	Open a command window and enter: start_adapter.bat

4. Wait five to ten seconds for the adapter to initialize.
   • The MyQuotes stream now contains two records. The MyOrders stream contains one record. Use the Event Stream Processor subscriber utility to view the content of the streams.
   • The orders.fix file now contains a NewOrderSingle message.
