Connector-specific configuration properties provide information needed by the connector agent at runtime. Connector-specific properties also provide a way of changing static information or logic within the connector agent without having to recode and rebuild the agent.
First Paragraph
Table 24 lists the connector-specific configuration properties for
the connector. See the sections that follow for explanations of the
properties.

Password used with UserID to log in to WebSphere Business Integration Message Broker.
Default = None.
If the ApplicationPassword is left blank or removed, the connector uses the default password provided by WebSphere Business Integration Message Broker.
User ID used with Password to log in to WebSphere Business Integration Message Broker.
Default = None.
If the ApplicationUserName is left blank or removed, the connector uses the default user ID provided by WebSphere Business Integration Message Broker.
Queue to which copies of successfully processed messages are sent.
Default = MQWFCONN.ARCHIVE
The character set for the queue manager connection. The value of this property should match that of the CCSID property in the queue URI. See Setting Queue Uniform Resource Identifiers (URI).
Default = null.
MQ server connector channel through which the connector communicates with WebSphere Business Integration Message Broker.
Default = none.
If the Channel is left blank or removed, the connector uses the default server channel provided by WebSphere Business Integration Message Broker.
Name of meta-object containing configuration information for the connector
Default = none.
Data handler class to use when converting messages to and from business objects.
Default = com.crossworlds.DataHandlers.text.xml
Meta-object passed to data handler to provide configuration information.
Default = MO_DataHandler_Default
Allows you to request a data handler based on a particular MIME type.
Default = text/xml
Specifies the verb to be set within an incoming business object, if it has not been set by the data handler during polling.
Default= Create
Boolean property to specify that the adapter should enable a message producer cache for sending request messages.
Default= true
Queue to which messages that could not be processed are sent.
Default = queue://CrossWorlds.QueueManager/ERROR
The name of the server hosting WebSphere Business Integration Message Broker.
Default = none.
Specifies how to handle in-progress events that are not fully processed due to unexpected connector shutdown. Choose one of four actions to take if events are found in the in-progress queue during initialization:
Default = Reprocess.
Message queues that will be polled by the connector for new messages. The connector accepts multiple semi-colon delimited queue names. For example, to poll the following three queues: MyQueueA, MyQueueB, and MyQueueC, the value for connector configuration property InputQueue would equal: MyQueueA;MyQueueB;MyQueueC.
The connector polls the queues in a round-robin manner and retrieves up to pollQuantity number of messages from each queue. For example, if pollQuantity equals 2, and MyQueueA contains 2 messages, MyQueueB contains 1 message and MyQueueC contains 5 messages, the connector retrieves messages in the following manner:
Since we have a pollQuanity of 2, the connector will retrieve at most 2 messages from each queue per call to pollForEvents. For the first cycle (1 of 2), the connector retrieves the first message from each of MyQueueA, MyQueueB, and MyQueueC. That completes the first round of polling and if we had a pollQuantity of 1, the connector would stop. Since we have a pollQuanity of 2, the connector starts a second round of polling (2 of 2) and retrieves one message each from MyQueueA and MyQueueC--it skips MqQueueB since it is now empty. After polling all queues 2x each, the call to the method pollForEvents is complete. Here's the sequence of message retrieval:
Default = queue://CrossWorlds.QueueManager/IN
Message queue where messages are held during processing. You can configure the connector to operate without this queue by using System Manager to remove the default InProgressQueue name from the connector-specific properties. Doing so prompts a warning at startup that event delivery may be compromised if the connector is shut down while are events pending.
Default= queue://CrossWorlds.QueueManaer/IN_PROGRESS
Number of messages to retrieve from each queue specified in the InputQueue property during a pollForEvents scan.
Default =1
Port established for the WebSphere Business Integration Message Broker listener.
Default = None.
Queue to which response messages are delivered when the connector issues requests.
Default = queue://CrossWorlds.QueueManager/REPLYTO
Maximum pool size for caching the sessions used during request processing.
Default = 10
Queue to which messages that are not subscribed are sent.
Default = queue://CrossWorlds.QueueManager/UNSUBSCRIBED
On a Create operation, if UseDefaults is set to true, the connector checks whether a valid value or a default value is provided for each isRequired business object attribute. If a value is provided, the Create operation succeeds. If the parameter is set to false, the connector checks only for a valid value and causes the Create operation to fail if it is not provided. The default is false.
