摘要： Methods, devices, and computer-readable media are provided for restoring state that was built up on a first session between a first server instance and a client to a second session between a second server instance and the client. Non-transactional session state that existed for the first session is preserved by repeating non-transactional commands in the second session. Transactions are executed in the second session when the transactions did not complete in the first session. The first server instance sends, to the client in the first session, information to maintain for a possible replay of commands that were sent in a request to the first server instance for execution in the first session. If the first session becomes unavailable, the maintained information may be used by the second server instance to restore the database session, masking the outage from users, applications, and clients.
