A KEN Channel is correlated to a specific type of notification. An example of a Channel’s use may be to send out information about upcoming Library Events or broadcast general announcements on upcoming concerts. Channels are subscribed to in the act of receiving notifications from a publisher or producer. They can also be unsubscribed to and removed from the data store from within the UI. The Channel Definitions are stored in the database table KREN_CHNL_T. The columns are listed as follows:
Table 2.2. KREN_CHNL_T
| Column | Description |
|---|---|
| CHNL_ID | Identifier for the Channel |
| NM | Name of the Channel represented in the UI |
| DESC_TXT | Description of the Channel |
| SUBSCRB_IND | Determines if the Channel can or cannot be subscribed to from the UI. This also determines if the channel will be displayed in the UI |
| VER_NBR | Version Number for the Channel |
Channels can be subscribed to through the UI and also through the direct access to the data store. To add a channel that can be subscribed to simply run the following SQL statement against the data store customizing value entries to your needs:
INSERT INTO KREN_CHNL_T (CHNL_ID,DESC_TXT,NM,SUBSCRB_IND,VER_NBR) VALUES (2,'This channel is used for sending out information about Library Events.','Library Events Channel','Y', 1)
