ABSTRACT:
A thread consistency support system10provides thread consistency from a Connector Application Program Interface50that creates multiple threads to a Thread-dependent Connector40that only allows a single thread to link to that connector for all operations on that connector. The system includes a Detection/Activation routine20that activates a Threading MetaConnector routine30in response to the Detection/Activation routine identifying a multi-threaded application60attempting to access a Thread-dependent Connector40. The Threading MetaConnector routine30interfaces between the Connector Application Program Interface50and the Thread-dependent Connector40. The Threading MetaConnector routine30establishes a connection handle for a single internal thread80with the Thread-dependent Connector40that is returned to the Connector Application Program Interface50of a calling multi-threaded application60in place of multiple requested thread connection handles. The connection handle is established in response to the Threading MetaConnector routine's receipt of multiple threads70from the Connector Application Program Interface50. The thread consistency support system10ensures that the same thread that initializes a connection from the Thread-dependent Connector40is used for all subsequent operations attempted by the multiple threads70from the application60with that connector.
