JMS working in XI

[Former Member]

Hi All,

Can some one explain how does JMS channel works in XI?

Is there any table where the JMS Mesasage id of the messages are recorded to check to duplication of messages?

Thanks and Regards,

hi,

The adapter identifies the resulting duplicate data record.

Select Handling of Pending PI Messages:

○ Throw Exception (Message Retry Possible Later)

○ Bypass Pending Warning and Send Message to JMS (Duplicates Possible)

A duplicate data record is created if the JMS commit is executed, but not the commit in the database of the Adapter Framework. If you select this option, you must make sure that this message has not yet been received in the JMS environment.

○ Mark Message as Delivered (Message Loss Possible)

The message is lost if the JMS commit is not yet executed. If you select this option, you must make sure that this message has already been received in the JMS environment.

Under Time Period for Duplicate Check for EO(IO) (secs), specify when the IDs are to be deleted.

To check for duplicate messages, IDs must be saved in the database. To prevent the database from getting unnecessarily large, these IDs are deleted after a certain amount of time.

For example, if you check message monitoring daily, deletion can take place after one day.

If the JMS receiver is an application, the JMS adapter should return a delivery acknowledgment. Select Send PI Delivery Acknowledgment (Adapter Is Endpoint)
