Method of detection and resolution thread-combined-deadlock in a thread pool based transaction processing system

摘要

The invention transaction as relates to a computer-readable recording medium recording a program for realizing the above method and a thread composite detection and resolution of the deadlock method in a transaction processing system based on the thread pool, based on the thread pool in the processing system, and easy to deadlock detection in which the thread with the lock not a general deadlock caused only by the locking between the transaction complex deadlock, how this detection and resolution of the thread compound deadlock to solve without withdrawal of the transaction and the method to provide a computer readable recording medium recording a program for realizing, occurs when assigning threads to the action units of the transaction in the transaction processing system and the thread pool is based on the locking and thread compound to and detecting a deadlock A method to solve this problem, in order to examine the complex deadlock between transactions requesting waiting for the lock transaction and the thread, the first step of irradiating only the cycle between the transaction requesting a lock that occupies the transaction requested by a thread; A second step of the other transaction requesting a lock that is occupied by a transaction that requests the thread relocate the thread that is currently occupied for the transaction requesting thread; And after completion of the transaction for requesting the thread, and a third step of re-assigning a thread for a transaction including a Relocation strung pohamreul, yiyongdoem transaction processing system or the like.
