Abstract
Techniques for recovering from session failures between clients and database servers are described herein. A first session may be established between a client and a first database server to handle a database query for the client. A request for data associated with the first session may be received by the first database server from the client, and the data retrieved. Prior to responding to the request, the data is spooled to a first session state stored in a repository made accessible by at least one computing device. The computing device(s) controls access to session states in the repository that correspond to sessions between clients and database servers. The computing device(s) enables sessions to be reestablished between the clients and database servers by accessing data of the session states in the repository and transmitting the data in response to messages received from the database servers containing session identifiers.
