Mediator includes a resequencer, which rearranges streams of related but out-of-sequence messages into their sequential order based on the type of resequencer used and the rules you define. When incoming messages arrive in a random order, the resequencer orders the messages based on sequential or chronological information, and then sends the messages to the target services in the correct order based on the resequencing configuration.

For more information about resequencing messages, see Resequencing in Oracle Mediator.
