Apparatus, system and for recycling rubbish

Abstract

The invention discloses a device, a system and a method for garage recovery. The method comprises the steps of collecting the running information of a system and application software, and determining whether to trigger garage recover according to the received data and preset judgment strategy; outputting a trigger massage if a trigger is needed; and triggering to execute garage recovery according to the trigger massage received by an execution device. The embodiment of the invention can provide self-protection according to predictable garage recovery time points, such that the system reduces system impact when executing garage recovery, and the data integrity is guaranteed; the system can control the execution of garage recovery during system idle period and small throughput period, thus reducing the system block caused by garage recovery; the system can recovery garage regularly, the execution duration is predictable, therefore, the execution time points, frequency and duration of garage recovery can be adjusted on the basis of different systems in order to reduce system cost.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a garbage collection device, system and method. Background technique [0002] At present, JAVA (a programming language) language has been widely used for its powerful software development, network programming ability, mobile phone programming ability and so on. In the JAVA language, memory management is performed by the JVM (JAVA virtual machine), and the JVM adopts an automatic garbage collection mechanism to release memory, specifically including: the JVM automatically judges the usage of the memory and starts the garbage collection mechanism; During the process, you only need to pay attention to the application of the object, and do not need to care about the space recovery problem when the object is discarded, which greatly facilitates the user's programming. [0003] After the JVM process discards the object, it needs to reclaim the space. However, when the JVM p...

Problems solved by technology

Because when the garbage collection is started, the system is in a blocked state during the garbage collection process. For a system with a large throughput and a large memory, the blocking time is relatively long, such as one minute. During this time, the application cannot process , leading to the stagnation of the entire system. For the real-time system of telecom applications, a large number of call losses and system overload will bring great losses. The greater the call volume, the more losses will be brought

Therefore, in the prior art, it is impossible to deal with the blocking problem that occurs during the busy or important period of the system caused by the process of garbage collection
