Advanced Queue Settings

Item	Name	Description
A	Retry Count Before Queue/Error	The maximum number of times the connector attempts to send the message before queuing or erroring.
B	Retry Interval (ms)	The amount of time (in milliseconds) that should elapse between retry attempts to send messages. This interval applies to both the queue and initial retry attempts.
C	Rotate Queue	If enabled, when any message fails to be sent from the queue, the connector will place the message at the end of the queue and attempt to send the next message. This will prevent a single message from holding up the entire queue. If the order of messages processed is important, this should be disabled.
D	Regenerate Template	Regenerate the template and other connector properties by replacing variables each time the connector attempts to send the message from the queue. If this is disabled, the original variable replacement is used for each attempt.
E	Include Filter/Transformer	If enabled, the filter and transformer is re-executed before every queue send attempt. This is only available when the Regenerate Template setting is enabled.
F	Queue Threads	The number of threads that will read from the queue and dispatch messages simultaneously. Message order is NOT guaranteed if this value is greater than one, unless an assignment variable is used below.
G	Thread Assignment Variable	When using multiple queue threads, this map variable determines how to assign messages to specific threads. If rotation is disabled, messages with the same thread assignment value will always be processed in order.
H	Queue Buffer Size	The buffer size for the destination queue. Up to this many connector messages may be held in memory at once when queuing.

Destination Settings

These are general settings that apply to all destination connectors. They include configuring the destination queue, whether to validate responses, and whether to re-attach attachments on outbound messages. Item Name Description A Queue Messages Never: Disable the destination queue. On Failure: Attempt to send the message first before queuing it. This will allow subsequent destinations and the Postprocessor to use the response from this destination if it successfully sends before queuing. Always: Immediately queue the message. Subsequent destinations and the Postprocessor will always see this destination's response as QUEUED. B Advanced Queue Settings Configure how often to re-attempt queued messages, increase queue threads, and more. C Validate Response Select Yes to validate the response. Responses can only be validated if the response transformer's inbound properties contains a Response Validation section. If validation fails, the message will be marked as queued or errored. For add

Message Storage Settings

Message storage settings enable you to determine how much message data your channel will store, whether to encrypt content, and whether to automatically delete content after messages are finished processing. This section of the Summary Tab enables you to determine how much message data your channel will store, whether to encrypt content, and whether to automatically delete content after messages are finished processing. Changing these settings may affect the availability of certain features, like queuing. Image of the Message Storage section of the Summary tab. Item Name Description A Storage Slider Use this slider bar to change how much data to store as messages process through the channel. The options are: Development: All data will be stored. Production: Everything except Processed Raw, Transformed, Response Transformed, and Processed Response content will be stored. Raw: Only Raw / Source Map content and attachments will be stored. Destination queuing is not supported in this mode,

Source Settings

These are general settings that apply to all source connectors. It includes configuring the source queue, the response to send back to originating systems, batch processing, and maximum processing threads. Item Name Description A Source Queue This determines whether the source queue is enabled. It also determines when the selected response will be sent back to the originating system. OFF (Respond after processing): Selecting OFF will process the message before sending the response. In this scenario you may use the response from destinations, the response map, or the post-processor. This is the Default selection. ON (Respond before processing): Selecting ON will queue messages and immediately send a response. In this scenario you may only choose to not respond with anything, or to use an auto-generated response. B Queue Buffer Size The buffer size for the source queue, only apply when Source Queue = ON. Up to this many connector messages may be held in memory at once when queuing. Defau

Channel Performance

Adjust the Message Storage slider so that the channel only retains the message data that you will actually need. If large messages are expected, use an Attachment Handler to improve throughput and reduce memory and disk usage. Enable source queuing if an auto-generated acknowledgement is sufficient for the upstream system. Enable destination queuing if you do not need to respond to the originating system from your destination. Increase the Max Processing Threads value if message order is not important and you may receive a large number of messages in a short time Increase the Queue Threads value if the downstream system can accept multiple concurrent connections. Clear the "Wait for previous destination" checkbox, unless you need destinations to process messages one after another. Use the "Destination Set Filter" feature in your source transformer when you need to route messages to only one (or a subset) of destinations in your channel. Adjust the Message Storage slider so that the cha

JMS Sender

This destination connector connects to an external JMS provider and writes messages to a queue or topic. It supports both JNDI and specifying a specific connection factory. Once this connector dispatches a message, the connection to the JMS provider will be kept open and cached until the connector is stopped or an error occurs. The properties view also includes a mechanism to save configuration templates for common provider types, so that creating a new JMS Sender is as quick and easy as possible. Note: Depending on the JMS connection provider you are using, you may need to include some external libraries (JARs) as a Library Resource and include them using the Set Dependencies dialog on the Channel Summary tab. For example, to use connection templates included for ActiveMQ and JBoss, you should download the libraries from their official site in order to use them with the JMS connectors. Supported property groups: Destination Settings Item Name Default Value Description A Use JNDI No Se

Scripts Tab

The Scripts tab is where channel-level scripts are configured. Select a script type from the drop-down list and edit the script in the text area.Select a script type from the drop-down and edit the script in the text area below. If a number appears next to "Scripts" in the tab, that number represents how many scripts have been edited from the default values. There is also a Reference List to the right for easy drag-and-drop of common helper methods / code templates. The following channel-level script types can be edited: Deploy Script: This script executes once when the channel is deployed. You have access to the global / global channel / configuration maps here. Typically this script is used to perform a one-time operation for the given channel, such as loading a properties file from disk, or instantiating a database connection. Undeploy Script: This script executes once when the channel is undeployed. You have access to the global / global channel / configuration maps here. Typically
