Now that you have a VMD file that detects duplicate messages, you will need to create a channel that filters the messages and ignores the duplicates:

• In the Iguana Dashboard screen, click Add Channel.

• From the Source and Destination list boxes, select the source component and destination component for your channel.

• Click Configure Channel.

• In the Channel name field, type the name of the channel (for example, duplicatetest).

• Click the Filter tab and select the Use filter check box.

• In the Full filter VMD path field, type or browse for the location of the VMD file that you have just created.

• In the Ignored messages field, type DuplicateMessage.

• Click Add Ignored Message. The Filter tab now indicates that messages that match the DuplicateMessage message definition are to be ignored:

• Click the Source tab. Update the fields in the source component of the channel as required.

• Click the Destination tab. Update the fields in the destination component of the channel as required.

• Click Add Channel to add the channel.

When you start the channel and send the test messages through it, the second message is recognized as a duplicate. A note is added to the logs, indicating that a duplicate message has been ignored:

Your channel is now ready for use, as duplicate messages are being successfully ignored.
