A client computer establishes one or more sessions with a DBMS. Session context information for each session is cached in a client-side session cache. When a session disconnection is detected, the session recovery includes establishing a new session with the DBMS, and restoring the session context of the disconnected session from the session information of the disconnected session that is stored in the session cache.
