IPC: G06F17/40
Filed: 2001-12-26
Abstract: PURPOSE: A database connection managing method is provided to request a database connection in a state that a transaction is started within a thread or there exists no transaction, and to enable a user to share one physical connection or to use non-share type physic connection in the same transaction. CONSTITUTION: The method comprises several steps. A connection manager checks whether there exists a transaction(S501), and generates a new connection or takes a connection from a pool(S502). If there exists a connection generated and shared in an existing transaction, the connection manager takes a corresponding connection from a storage. In a case that a new connection is generated or a connection is taken from a pool, an internal local transaction is generated for committing a physical connection, the local transaction is transmitted to a synchronization object, and it is registered at a transaction(S503, S504). It is checked whether an XAResource(Transaction Associator Resource) of the transmitted connection is registered(S505). In a case that the transmitted connection is not relevant to the transaction when it is used by a client, the connection manager makes the connection relevant to the transaction via an algorithm, and stores the connection at a storage.
