Communication Channel Details

Use

You can use the communication channel monitor to find information about communication channels. After you perform a search, the system displays the results in a table.

Prerequisites

You have accessed the communication channel monitor and performed a search. For more information, see Searching Communication Channels .

Result

The table with results of the search contains the following communication channel details:

Column	Meaning
Communication channel	Name of the communication channel.
Status	Status of the communication channel. The following statuses are possible: : channel is started and functioning without errors. : channel is started but errors have occurred. : channel is started, but inactive. : channel is stopped. : adapter is not registered; no information about channel available.
Short Log	Explanation of the status of the communication channel and, in the event of an error, the type of error that has occurred.
Control	How the communication channel is controlled: Manual : you control the communication channel by choosing Start or Stop . Automatic : the communication channel is controlled by scheduled availability times. External : The communication channel is controlled by an HTTP request.
Processing Errors	When the last processing errors occurred in the communication channel. If no errors occurred, the column remains empty.
Partners	The communication party (if available) that is specified in the communication channel.
Component	The communication component that the communication channel is assigned to.
Adapter Type	The type of adapter that has been selected and configured for the communication channel.
Namespace	The namespace that contains the respective adapter type.
Direction	The direction of the communication channel: sender or receiver channel.
Number of Nodes	The number of nodes if the communication channel consists of multiple instances on different nodes of a server cluster.

You can also show or hide the basic details of a communication channel selected in the table by choosing Details .

You can choose what information should be displayed in the table in the following ways:

Use the Options dropdown menu to select the table size.
Use the filtering functionality to narrow the search results.

Inactive Channels

While channels with Inactive status are started, they are inactive on all cluster nodes of a server cluster. This means that a channel is not processing any messages, even though it is started. A channel has this status in the following cases:

The channel is configured as inactive in the Integration Directory (it can also only be reactivated in the Integration Directory).
The channel is set to inactive by the respective adapter (some adapters can do this and can also change this status if necessary).

Analyzing Communication Channel Details

When you select a communication channel, the system displays further information related to the status of the channel and its administration.

If the channel consists of multiple instances on different nodes of a server cluster, this information about the channel status is provided for each cluster node.
- The information that is displayed for the status of a channel on the individual cluster nodes is information that is accumulated to give the overall status of the channel in the table of communication channels.
  
  If the cluster nodes have at least one status that is above all other statuses in the status hierarchy, the channel receives this status as the overall status. The possible statuses correspond to those in the table of communication channels and have the following hierarchy:
  
  > > >
  
  A combination of Running or Inactive with Stopped statuses is not possible.
- The processing details displayed for the selected cluster nodes provide current runtime information on message processing. Depending on the adapter used, the type and occurrence of the information can differ.
  
  This information forms the entry in the Processing Errors column in the table of communication channels. The newest result is taken from the table of the cluster nodes.
  
  When you find a channel with errors you can search the Processing Details table for failed messages. To find more information, you can use the corresponding link in the Message ID column. The link leads to the message monitor, where you can find why the message failed and how to solve the issue. For more information, see Reviewing Search Results .
The information about channel administration displays when and by whom a channel was previously started or stopped.

You can only start or stop a communication channel for an entire server cluster, not on individual cluster nodes. However, since errors can occur on individual cluster nodes during the execution of these actions, error information is also displayed for each cluster node.
If the channel is controlled automatically, this means that the Availability Times tab page is displayed.

All other availability times that are relevant for this channel are also displayed. You can exclude specific availability times and, if necessary, reschedule them.

Since only active availability times are displayed, it is possible that availability times do exist for the selected communication channel, even if none are displayed.
The information on the Configuration Settings tab page displays how often an attempt is made to send messages to this channel, and at what time intervals.

The default settings are taken from the outbound properties for the Java service XPI Adapter: XI. You can overwrite and save these values. You can also restore overwritten values. Information about changes made to the settings is always displayed.

Note
The Configuration Settings tab page is only relevant for receiver channels and is therefore only displayed for channels of this type.
