Embodiment 1

[0048] The present embodiment provides a garbage collection method of a Java virtual machine, such as figure 1 shown, including steps:

[0049] S11: Detect the usage rate of the old generation of the Java virtual machine through the detection process of the business server;

[0050] S12: Determine whether the usage rate of the old generation reaches the preset threshold, if so, send a notification to suspend the business request of the current business server to the notification process of the load balancer and start garbage collection, otherwise, continue to wait.

[0051] The acronym for Java Virtual Machine is JVM. JVM is a specification for computing equipment. It is a fictitious computer that is realized by simulating various computer functions on an actual computer.

[0052] In order to improve server performance, load balancer plus business server mode is widely used at present, such as Figure 9 as shown, Figure 9 It is a schematic diagram of a load balancing depl...

Embodiment 2

[0072] The present embodiment provides a garbage collection method of a Java virtual machine, such as image 3 shown, including steps:

[0073] S31: Detect the usage rate of the old generation of the Java virtual machine through the detection process of the business server;

[0074] S32: Determine whether the usage rate of the old generation reaches the preset threshold, if so, send a notification to suspend the business request of the current business server to the notification process of the load balancer and start garbage collection, otherwise, continue to wait;

[0075] S33: Determine whether the garbage collection has ended through the JVM log, and if so, send a notification of resuming the service request of the current service server to the notification process of the load balancer; otherwise, continue to wait.

[0076] The difference between this embodiment and the first embodiment is that step S33 is further included.

[0077] Specifically, it is judged whether the ...

Embodiment 3

[0086] The present embodiment provides a garbage collection method of a Java virtual machine, such as Figure 5 shown, including steps:

[0087] S51: Detect the JVM information and JVM log of the Java virtual machine at a preset time interval T;

[0088] S52: Detect the usage rate of the old generation of the Java virtual machine through the detection process of the business server;

[0089] S53: Determine whether the usage rate of the old generation reaches the preset threshold, if so, send a notification to suspend the business request of the current business server to the notification process of the load balancer and start garbage collection, otherwise, continue to wait;

[0090] S54: Determine whether the garbage collection has ended through the JVM log, and if so, send a notification of resuming the service request of the current service server to the notification process of the load balancer; otherwise, continue to wait.

[0091] The difference from Embodiment 1 and Em...

Abstract

The invention discloses a garbage collecting and load balancing method and system of a Java virtual machine and aims to solve the problem that the Java virtual machine pauses and affect service when performing global garbage collection. The garbage collecting and load balancing method comprises the steps that S1, the tenured generation usage rate of the Java virtual machine is detected through a detection process of a service server; S2, whether the tenured generation usage rate reaches to a preset threshold value or not is judged, if yes, a notification for pausing a service quest of the current service server is sent to a notifying process of a load balancer, garbage collection begins, and if not, waiting continues. By adopting the garbage collecting and load balancing method, the problem of server pausing produced by garbage collection of the Java virtual machine in a cluster environment is solved.

Description

technical field [0001] The invention relates to the technical field of load balancing, in particular to a method and system for garbage collection and load balancing of a Java virtual machine. Background technique [0002] With the development of Internet technology, servers are used more and more widely, and Java, as one of the most popular high-level languages, is widely used in many companies. In order to improve the performance of the server, the mode of load balancer plus business server is generally adopted at present. [0003] Since the bottom layer of Java uses JVM technology, it effectively solves the memory leak problem caused by C / C++, but its garbage collection mechanism affects its performance. There are two main types of JVM garbage collection, Monitor GC and Full GC. The monitor GC takes a relatively short time and generally takes tens of milliseconds to complete, which will not have much impact on the business. However, the Full GC may sometimes take as lon...
