Replication Server normally uses command tags for two purposes:
To reassemble the commands in a transaction so that data servers at remote sites execute the transaction as a unit
To ensure that each command is processed only once
The syntax for command_tags is:
[@origin_time=datetime_value]
@origin_qid=binary_value
@tran_id=binary_value
[@mode=0x08]
[@standby_only={1 | 0}]
