About Configuring the Source Connector

If Guarantee Message Order is enabled in the Source Connector of a channel, only one message will be processed at any time across the entire cluster for that particular channel. Additionally, if the source queue is enabled, it will be processed only on one node in the cluster. Parent topic: About Guaranteed Message Order

About Guaranteed Message Order

Guaranteed message ordering is used to ensure that messages received by a channel are processed in the order that they are received. This reduces the throughput of the channel, so it is important to configure the IP address and port for each node in the cluster in order to mitigate the decrease in performance. (For details about IP address/port, see About IP Address and Ports.) About Configuring the Source Connector About Configuring a Destination Connector

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

Destination Table

This table shows you all currently configured destinations for your channel. You can see at a glance the type of each destination, whether it is enabled, what chain it belongs to, and more. Column Description Status Indicates whether the destination is enabled or disabled. Only enabled destinations process messages. A channel must have at least one destination enabled. Destination Double-click this cell to edit the name of the destination. Note that while a destination may be renamed, its metadata ID will remain the same. Id The metadata ID that uniquely identifies this destination within the current channel. Connector Type The type of destination connector. To change this, select the destination from the table and choose a new type from the drop-down menu directly below the table. Chain The chain this destination connector belongs to. The first destination in the table is automatically placed into chain #1. To start a new chain, select a subsequent destination from the table, and unch

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

Metadata Table Columns

Column Description Id The unique ID that identifies the message within the current channel. Note that a single message can have multiple connector messages for each connector (source / destinations) in the channel. Each connector message row is organized by this column in the table. Connector The name of the connector. (e.g. "Source", "Destination 1") Status The current status of the connector message. Valid values include: Source connector statuses: Received: If the source queue is enabled, this means the message has been committed to the database and added to the source queue, but has not yet been processed. If the source queue is disabled, this means the message has not yet finished processing through the source connector. Filtered: The message has been rejected by the source filter, and will not flow any further through the channel. Transformed: The message has passed the source filter/transformer, and the source encoded data has been dispatched to any destinations. Error: An error
