XES recognizes a valid connection to a lock structure through the connect token (CONTOKEN), which the system returns after the successful completion of the IXLCONN service. To use the IXLRT service, you must specify your valid connect token on every IXLRT request.

If you do not provide a valid CONTOKEN, there is a possibility that XES will terminate abnormally while processing the request. You should establish recovery procedures for this circumstance.
