Specifies the name of the JMS property, header field, or system value that contains the txid used to uniquely identify transactions. This value must increment for each transaction.

delim.txid={field_name|$jms_property|*txid}

For most cases using the system value of *txid is preferred.

For example:

delim.txid=$JMSTxId
delim.txid=*txid
