Outbound sequence collection

WAS v8.5 > Reference > Sets
Outbound sequence page

This page displays the collection of outbound sequences for the current scope. Outbound sequences are used to transmit messages reliably from the local application to the remote endpoint. Each sequence has a unique identifier.

To view this page in the console, click one of the paths to this panel. For example Servers > Server Types > WebSphere application servers > server_name > [Additional Properties] Reliable messaging state > Runtime > Outbound sequences.
To browse or change the properties of a listed item, select its name in the list.
To act on one or more of the listed items, select the check boxes next to the names of the items to act on, then use the buttons provided.
To change what entries are listed, or to change what information is shown for entries in the list, use the Filter settings.
The WS-ReliableMessaging runtime panels are available at many different scopes within the dmgr console. For more information, see WS-ReliableMessaging - dmgr console panels.
The following icons are displayed here and on several other reliable messaging runtime panels:

Icon Name Description
OK Everything here, and (if there is a link) in all runtime panels below this link, is running normally.
Warning Something here, or (if there is a link) in one of the runtime panels below this link, is in an unusual state and you might have to take some action to resolve it.
For example, the system might be awaiting a response from an endpoint. In this case, either the response will be received (in which case you need take no action and the runtime information will be updated to "OK") or the reliable messaging destination has stopped acknowledging messages (in which case we have to take some action to resolve the failed sequence).
Error There is a definite error that you must take some action to resolve, either here or (if there is a link) in one of the runtime panels below this link.
Note that for troubleshooting purposes you only have to follow links to the sub-panels if states other than "OK" are displayed.

You might see more sequences than you expect, due to sequence reallocation. If a sequence is reallocated, the original and new sequences are both visible.

Sequence identifier

This URI is the unique identifier for the sequence.

Associated application

The application that created the sequence.

Target endpoint URI

The destination to which messages are transmitted.

Message depth

The count of messages, held by the reliable messaging layer, that have not yet been transferred.

Messages sent

The total count of messages sent by the application for this sequence.

Details

The current state of the sequence. "Establishing" indicates the sequence is awaiting a CreateSequenceResponse message from the reliable messaging destination; "Active" indicates the sequence has been established; "Cannot contact the remote endpoint" indicates the sequence has been established but the reliable messaging destination has stopped acknowledging messages; "Sequence closing" indicates the sequence is closing and will accept no new messages; "Sequence closed" indicates the sequence has been closed and will accept no new messages; "Sequence terminating" indicates the sequence is terminating and will accept no new messages; "The inbound side has lost state in a terminate" indicates the sequence has terminated with unacknowledged messages outstanding; "The sequence has timed out" indicates the sequence has timed out.

Status

The icon indicates "OK", "Warning" or "Error" as previously described on this page. A more precise indication of the sequence state is given in the "Details" column.

Buttons

Button Description
Export unsent messages Export the messages from the selected sequences to compressed files. If you select any sequences that have no messages to export, a warning or error message is displayed.
Close sequence Close the selected sequences and send a CloseSequence message to indicate the sequence is complete and will not be sending any further messages. The close protocol does not delete the resources for the sequence, so we can still access any undispatched or unsent messages. If we are using v1.0 of the WS-ReliableMessaging specification (which does not support this option) an error message is displayed. For more information about the reliable messaging close protocol, see WS-ReliableMessaging: supported specifications and standards.
Terminate sequence Close the selected sequences and send a TerminateSequence message to indicate the sequence is complete and will not be sending any further messages. The terminate protocol deletes all resources for the sequence. For more information about the reliable messaging terminate protocol, see WS-ReliableMessaging: supported specifications and standards.
Terminate sequences only if necessary. Refer to the description of the Delete sequence button for more information.
Delete sequence Delete the selected sequences and all their messages, without sending a TerminateSequence message.
Delete or terminate sequences only if necessary. If you delete or terminate an active sequence, the resulting messaging behavior is unpredictable and can cause loss of messages. If you are not sure whether we can safely delete or terminate a sequence, do not delete or terminate it; the system automatically deletes sequences that have been inactive for 12 hours.
