DCS transport channel settings
Use this page to view and configure a DCS transport channels, which are used to handle inbound Distribution and Consistency Services (DCS) messages.
By default, two channel transport chains are defined for an application server that contains a DCS channel:
- The chain named DCS contains a TCP and a DCS channel.
- The chain named DCS-Secure contains a TCP, an SSL, and a DCS channel.
Both of these chains terminate in, or use the same TCP channel instance. This TCP channel is associated with the DCS_UNICAST_ADDRESS port and is not used in any other transport chains. One instance of an SSL channel is reserved for use in the DCS-Secure chain. It also is not used in any other transport chains.

Click on view associated transports for the port associated with the DCS transport channel whose settings you want to look at. For example...
- Transport channel name
Name of the DCS transport channel.
This name must be unique across all channels in a WebSphere Application Server environment. For example DCS and TCP transport channels cannot have the same name if they reside within the same system.
- Discrimination weight
Specifies the priority this channel has in relation to the other channels in this transport chain. This property is only used when port sharing is enabled and the channel chain includes multiple channels to which it might forward data. The channel in the chain with the lowest discrimination weight is the first one given the opportunity to look at incoming data and determine whether or not it owns that data.
The discrimination weight of the DCS channel in a DCS-Secure transport chain should always be less than the discrimination weight of the SSL channel that is in that chain. Other SSL channels in other chains might have different discrimination values.
Data type Positive integer Default 1 for the DCS channel 2 for the SSL channel
