Use the Pagoda Panel to optimize the configuration of the Java virtual machine
Jun 21, 2023 pm 02:52 PM
With the continuous development of the Internet, more and more applications and businesses require the use of programs developed in the Java language. For the running of Java programs, the performance of the Java Virtual Machine (JVM) is very important. Therefore, optimizing configuration is an important means to improve the performance of Java applications. Pagoda panel is a commonly used server control panel that can help users manage servers more conveniently. This article will introduce how to use the Pagoda panel to optimize the configuration of the Java virtual machine.
Step one: Install Java virtual machine
First you need to install the correct version of Java virtual machine on the server. You can query it with the following command:
java -version
If it is not installed, you need to use the following command to install it:
yum install java-1.8.0-openjdk-devel.x86_64
Step 2: Add the Java application in the Pagoda panel
Open the Pagoda management panel and move the mouse to the "Website" option in the left menu bar, then select "Add Site", enter the site-related information and save it.
In the site list page, click on the site name just added to enter the site setting interface. In the "Application" option, select "Java" and fill in the parameters required for Java to run.
Step 3: Configure JVM parameters
Enter the conf directory under the site directory, edit the file server.xml, and find the following code segment:
<Connector executor="tomcatThreadPool" port="80" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="443" />In this code Below, add the following code:
<Executor name="tomcatThreadPool" namePrefix="catalina-exec-"
maxThreads="400" minSpareThreads="25"
maxIdleTime="60000" />This can increase the processing power of the Tomcat container and significantly improve the performance of Java applications.
In the same server.xml file, find the following code segment:
<!-- maxThreads：啟用的最大線程數(shù)；minSpareThreads：保留的最小線程數(shù)； -->
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />Modify the maxThreads and minSpareThreads parameters, for example, to the following:
<Connector port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" maxThreads="800" minSpareThreads="50"/>This will make The Tomcat container is more stable and its performance is effectively improved.
Step 4: Set JVM parameters
Enter the conf directory under the site directory again, find the file catalina.sh, and edit the file. Add the following code at the end of the file:
JAVA_OPTS="-server -Xms2048m -Xmx5296m -Xmn2048m -XX:MetaspaceSize=512M -XX:MaxMetaspaceSize=1024m -XX:SurvivorRatio=6 -XX:+DisableExplicitGC" export JAVA_OPTS
This code sets some parameters of the Java runtime, such as heap memory size, Metaspace size, etc. Depending on the actual situation, these parameters can be adjusted appropriately to obtain better performance. After this setting, the Tomcat container will use a more efficient garbage collection method and a more reasonable memory allocation method, thereby improving the execution efficiency of Java programs.
Step 5: Restart the server or Tomcat container
After completing the above settings, you need to restart the server or Tomcat container for the settings to take effect. You can operate it in the Pagoda management panel, or use the following command:
systemctl restart tomcat
Summary
The above are the relevant steps for using the Pagoda panel to optimize the configuration of the Java virtual machine. With reasonable settings, the performance of Java applications can be significantly improved and made more stable and reliable. When optimizing the configuration, reasonable adjustments need to be made based on the actual situation to obtain the best performance.

How does the Java virtual machine use reference counting for memory management?
Apr 13, 2024 am 11:42 AM
The Java virtual machine uses reference counting to manage memory usage. When the reference count of an object reaches 0, the JVM will perform garbage collection. The reference counting mechanism includes: each object has a counter that stores the number of references pointing to the object. When the object is created, the reference counter is set to 1. When an object is referenced, the reference counter is incremented. When the reference ends, the reference counter is decremented.
