Duplicate Message Detection TIBCO BusinessConnect SOAP Protocol checks for duplicates on all inbound and outbound messages. If duplicates are found, the duplicate field value in the request or response message sent to a private process is set to true. Inbound Messages For inbound messages, duplicate detection is performed in the same way for the inbound request and inbound response. Duplicate detection criteria for the inbound request and inbound response messages are as follows: • Protocol name • Protocol version • Installation name • Host name • Trading partner name • Operation ID • Body element of the SOAP envelope Outbound Messages For outbound messages, duplicate detection is performed only for the outbound request received from a private process. Duplicate detection criteria for the OutboundRequest messages are as follows: • Protocol name • Protocol version • Installation name • Host name • Trading partner name • Transaction ID • Operation ID • Request coming from the private process (no header) The domains of the host and trading partner in private process request messages are not taken into consideration when performing duplicate detection. Only the values hostname and tpname are considered.
