Abstract:
1. A method for substituting a new version resource adaptor for a production version of the resource adaptor, the method comprising: establishing a connection between a server and an enterprise information system by way of the production version resource adaptor that provides a driver for said connection; transmitting message traffic from the server to the enterprise information system over the production version resource adaptor; receiving a request to replace the production version resource adaptor with the new version resource adaptor; commencing a versioning process by the server by sending an indication from the server to the new version resource adaptor that the new version resource adaptor is to replace the production version resource adaptor in processing the messages from the server; sending a start versioning message to the production version resource adaptor to inform the production version resource adaptor to begin migrating services from the production version resource adaptor to the new version resource adaptor, wherein after receiving the start versioning message, the production version resource adaptor migrates all clients and inbound transactions to the new version resource adaptor; receiving an indication from the production version resource adaptor to the server indicating that migration is complete; directing the message traffic to the new version resource adaptor after the indication is received from the production version resource adaptor to the server indicating that replacement is complete; and sending a stop message from the server to the production version resource adaptor, instructing the production version resource adaptor to take itself offline.
