Tools and Handlers
Every CIC server has an event-handling engine called an Interaction Processor (IP). As part of its responsibility, the IP engine invokes handlers including those handlers that communicate with one another across multiple sites. You create Multi-Site messages in handlers using a set of Multi-Site and IpNotes tools available in Interaction Designer.
Using the Multi-Site messaging tools, you can construct an arbitrary message format within a handler and receive that message in another handler on a remote server. The order in which you add the various elements to the message determines the format of the message. On the receiving end, the handler must read the elements from the message in the correct order. The handler checks the element type when it reads it, so an attempt to read the wrong element type results in an error.
When a message is ready to send, the sender specifies a destination site ID; and the object and event values to use to start the notification on the receiving server.
Messages send asynchronously, requiring no response, or synchronously,
where the sending tool waits a specified amount of time for the return
of a response message. The handler reads the response message in the exact
same way as the original message by using the get tools in
the same order as the sender used the put tools.
To assist you with understanding how these tools work, Genesys provides three sample message handlers Along with these samples are detailed descriptions of the parameters associated to each tool. These samples provide guidance on how to set the inputs and what to do with the outputs of each tool.
