Thread pool managing method and system

Abstract

The invention discloses a thread pool managing method and system. The system comprises a working thread creating unit, a detecting thread creating unit, a working thread calling unit, a heartbeat signal detecting unit and a zombie thread processing unit. The managing method includes: creating a working thread, and delivering the same into a thread pool queue; creating a detecting thread; calling the working thread in the thread pool queue to execute a task; using the detecting thread to detect whether the heartbeat signals of each working thread is received or not in a heartbeat cycle; using the detecting thread to set the working threads whose heartbeat signals are not received in the heartbeat cycle as zombie threads, releasing all the resources of the zombie threads, and notifying a user of the fault positions through a user interface. The method and system has the advantages that the working threads in the thread pool are managed through the thread pool, dependence on operating system management is avoided, zombie threads can be detected timely and accurately, and the fault positions in programs using the zombie threads to execute tasks can be found and notified to the user.

Description

technical field [0001] The present invention relates to thread pool technology, and more specifically, relates to a thread pool management method and management system. Background technique [0002] In an application based on object-oriented programming, it takes a lot of time to create and destroy objects because creating an object requires memory resources or other more resources. Taking an application based on Java programming technology as an example, the JVM (Java Virtual Machine) will try to track each object so that system resources can be recovered after the object is destroyed. [0003] In addition, in addition to the overhead of creating and destroying threads, active threads also consume system resources. If a large number of threads are generated in a short period of time, the system may run out of resources due to excessive memory consumption or excessive switching. In order to prevent insufficient resources, server applications need some way to limit the numb...
