Abstract
A method and system for managing operational states of database tables within a multiple-database system. If a particular user session issues a query against a target table that causes a data inconsistency, the target table transitions into an errant state and the session will become interrupted. This errant state is then propagated onto any other table associated with the user session. A session-level recovery process can thereafter be executed to repair and restore database tables associated with the interrupted user sessions without the need to take an entire database system offline.
