Description

The Operations are grouped into Channels, how organize the Operation within the Channels is a choice of GreenVulcano® ESB developer

Usually the Operations are grouped by:

  • Technology: Some servers may have different technological interfaces (eg HTTP, RMI), then you can allocate additional channels to group operations based on the technology used.
  • Abstraction: It 'possible that a system is actually composed of several heterogeneous systems (such a situation can occur, for example, during a migration, or due to modification or replacement of systems). For each subsystem is possible to build a Channel.

VulCon / GV Console Configuration

The Channel is identified by an unique attribute id-channel, this attribute is unique within the System entity. The Channel subelement are the Operations, GreenVulcano® ESB offers a wide variety of Operations that you can use in your service. See plugins section.

How To

From the VulCon® Core view, it is possible to insert a new Channel by right clicking the System element you are working on. Then Insert after and press Channel*. A new Channel element will be created. Fill the id-channel property in the properties view. Now you can insert all the operations needed.
