When the start command is executed, it configures and starts the command and control interface, starts the adapter, establishes a connection to an SAP system, and connects the ESPPublisher and ESPSubscriber components to Event Stream Processor via the SDK interface.
The adapter ignores the start command if it is executed when there is a running instance of the adapter, and sends a warning.
You can have multiple instances of the adapter running. To do this, each adapter requires its own copy of the adapter configuration file which contains a unique controller port.
