Managing Channels
About Channels
A channel is a topic or identifier that acts as a conduit for related
information. The channel
carries the information from the publishers who created
it to the subscribers who want it.
A channel has a name, a description, a subject, keywords, and a persistent
store associated with it. A channel also has individual and group subscribers
associated with it. Subscribers can be event subscribers or package subscribers.
The Publishing Framework plug-in to SAS Management Console provides a
New Channel Wizard, which enables you to define all the properties of a channel, including
what subscribers are associated with it.
Each association of a subscriber to a channel is a subscription.
A subscription enables the information that is published to a channel to be delivered to
the interested (subscribed) users.
You should create a channel for each distinct topic or audience. For instance,
users of a particular application might want a channel for discussion and data exchange,
while the programmers of that application might want another channel to discuss technical problems
and future enhancements. Although the topic is the same application, the discussion and
data exchanged will be very different, so two separate channels would probably best serve
the needs of the two groups of users.
Create a Channel Folder
If you anticipate creating a large number of channels, then consider grouping
related channels into channel folders. You can create subfolders within folders,
thereby creating a folder hierarchy to which access controls can be applied.
To create channel folders:
- From the SAS Management Console navigation tree, expand the Publishing
Framework node.
- Select the desired metadata repository node.
- If you are creating a top-level folder, then select Channels.
If you are creating a subfolder, then navigate to and select
the desired parent folder.
- From the menu bar, select Actions
New Folder. The New Channel Folder wizard displays.
The New Channel Folder wizard guides you through the process of creating a
channel folder. Click Help in the wizard at any time for more
information about the current window.
You can create a subfolder by selecting the desired parent folder
and selecting Actions
New Folder from the menu bar.
Note: Currently it is not possible to move an existing
channel into a folder or from one folder to another. Plan ahead to avoid having
to delete and recreate channels.
Create a New Channel
To create a new channel:
- From the SAS Management Console navigation tree, expand the Publishing
Framework node.
- Select the desired metadata repository node.
- If you are creating a channel within a folder, select the Channels node and navigate to the
desired folder.
- Select the Channels item or the desired folder
and select Actions
New Channel from the menu bar to open the New Channel wizard.
The New Channel wizard guides you through the process of creating a new
channel. Click Help in the wizard at any time for detailed
information. For an example, see
Example: Creating a Channel.
Duplicate an Existing Channel
To create a channel with substantially the same properties as an existing
channel:
- In the SAS Management Console navigation tree, expand the Publishing
Framework node.
- Select the desired metadata repository node.
- Select the Channels node and, if applicable, navigate to the folder
where the existing channel is stored.
- Select the existing channel and select Actions
Duplicate Channel from the menu bar
to open the New Channel wizard. All of the wizard's fields are
filled in with values from the existing channel.
- Because channel names must be unique, you must change the Name
attribute. Click Next to change other attributes.
- Click Finish to create the new channel.
Modify an Existing Channel
To modify the properties of an existing channel:
- In the SAS Management Console navigation tree, expand the Publishing
Framework node.
- Select the desired metadata repository node.
- Select the Channels node.
- If applicable, open the appropriate folder(s) to navigate to the
desired channel.
- Select the channel that you want to modify and select File
Properties from the menu bar.
The Properties window for that channel displays.
- Use the tabs in the Properties window to modify the various properties.
- When you are finished modifying properties, click OK.
Delete a Channel
To delete a channel:
- In the SAS Management Console navigation tree, expand the Publishing
Framework node.
- Select the desired metadata repository node.
- Select the Channels node.
- If applicable, open the appropriate folders to navigate to the
desired channel.
- Select the channel that you want to delete and select Edit
Delete from the menu bar.
To delete a channel folder (including any subfolders and channels under it),
right-click the folder and click Delete.
To delete all channels, right-click the Channels item and click
Delete.
