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.

摘要： Systems and methods are provided for supporting transaction recovery based on inline delegation of transaction logs to a database. The system can retrieve transaction recovery information of a transaction from a persistence store, wherein the transaction recovery information is persisted on a resource manager that is associated with the persistence store during a prepare phase. Furthermore, the system can retrieve one or more in-doubt transactions from one or more participating resource managers of the transaction. Then, the system can determine whether to commit or roll back the one or more in-doubt transactions by matching the one or more in-doubt transactions to the transaction recovery information.

摘要： Techniques described herein distinguished between global transactions in a session managed by a transaction manager, and those in the same session that are managed by the resource manager using the optimizations. The techniques provide a guaranteed commit outcome when the commit is managed by the resource manager, or when a transaction manager is managing the transaction. Switching between the different techniques to provide a guaranteed outcome occurs in a safe, performing, and silent manner, based on who controls the current transaction in a session. The solution includes one-phase processing, read only optimizations, and promotable transactions.
