Creating Channels
Channels are the logical meeting points for data that is published and subscribed to. If you are using Universal Messaging Provider for JMS, channels are the equivalent of JMS topics.
Each channel consists of a physical channel on the Universal Messaging realm as well as its logical reference in a namespace that may comprise resources that exist across multiple Universal Messaging realm servers. When you create a channel in the Enterprise Manager, a physical object is created on the realm. You can also obtain references to the channel by using the Universal Messaging Client and Admin APIs. You can create a channel in the following ways:
Create the new channel directly under the realm node.
Create a container node (folder) that contains the new channel.
Add the new channel to an already existing container node.
When you connect to a Universal Messaging realm in the Enterprise Manager, all resources and services found in the realm namespace are displayed in a tree structure under the realm node.
To create a channel in the Enterprise Manager
1. Expand the Realms node.
2. Select a realm, right-click it, and then select Create Channel.
3. In the Add channel dialog box, specify a name for the channel.
If you want to create a new container node, you must specify the absolute name of the channel. For example, to create a channel named "rates" in a new container named "eur", type
eur/rates. For more information about the valid channel names, see
Valid Channel Names.
4. Specify the other channel attributes to configure the behavior of the channel.
5. (Optional) To configure the operational environment of the channel, edit the storage properties associated with the channel.
6. (Optional) If you want to publish Protobuf events on the channel, upload a Protobuf descriptor.
7. (Optional) To create a channel key, under Channel Keys, click New and specify the key name and depth.
8. Click OK.
