ABSTRACT:
A DB2 thread cancellation method permits operator intervention to terminate a DB2 thread. After the thread to be canceled has been located, a series of one or more SRBs is scheduled to cancel the thread. The basic approach is an iterative one, involving (1) making the thread nondispatchable, i.e., freezing execution of work associated with the thread to prevent such work from making undesirable environmental changes while the thread canceling operation is in progress, (2) testing to ensure that canceling the thread at that moment will not create certain undesirable side effects, primarily in the context of serialization of DB2 resource usage; (3) invoking the DB2 thread cancellation routine; (4) making the thread dispatchable again to permit the cancellation process to begin; (5) receiving a message whether the cancellation request was completed successfully, and (6) returning a status code indicating a successful or unsuccessful cancellation attempt. The foregoing steps are repeated until a success status code is received or until a timeout, i.e., until a specified number of unsuccessful attempts has been made.
