LLP Listener |

|
This documentation page describes a feature of version 3.3 of Iguana. For information on how to configure the LLP Listener source component in version 4.0 or later of Iguana, see LLP Listener. | ||
 |
In order to configure the LLP Listener source component described in the Channel Source Components section of the manual, you must define the properties described in the table below.
| Property | Description |
|---|---|
| Port* | Port that you will listen on for LLP encoded HL7 messages. For information on how to manage ports effectively, see Port Management Tips. |
| ACK VMD Path | Location of the VMD file used to generate an ACKnowledgment message to respond to each successfully consumed HL7 message. By default, the "autoack.vmd" file found in the Iguana install directory is used. An ACKnowledgment VMD file must be set up to parse out pertinent information from the incoming message and return the information in an ACK message. The "autoack.vmd" is already set up like this. However, you may also specify your own ACK VMD file if you want to send back a non-standard ACK. To get a feel for how the autoack.vmd does its job, see Auto ACKnowledgments. |
| NACK VMD Path | Location of the VMD file used to generate a Negative ACKnowledgment message to respond to each HL7 message consumption failure. By default, the "autonack.vmd" file found in the Iguana directory is used. Alternatively, you may specify your own VMD file to use by putting its absolute path here. |
| NACK all errors | This is "false" by default, meaning that NACKs are sent back only if there was an error in logging the message to the database. If logging was successful, an ACK will always be sent. If this item is set to "true", NACKs will be sent whenever a component encounters an error while processing the message. In this case, ACKs are sent only if the message was successfully processed by the entire channel and if the message was successfully logged to the database. |
| Connection timeout (minutes) | If the channel receives no messages for this amount of time, Iguana will automatically disconnect the LLP Listener. If you never want Iguana to stop channels in this way, set this value to '0', which stands for 'Unlimited'. |
| Automatically purge error logs older than | Specify when error logs are stale and can be deleted. If this value is 0, then error logs will never be automatically purged. |
