This document is intended to describe the steps required to deploy Joget Large Enterprise Edition (LEE) in a clustered environment for scalability and redundancy.

Requirements

In order for clustering to work, the Starting from Joget DX 8, Large Enterprise Edition is no longer required for clustering to work. The standard Enterprise Edition will not work due to licensing restrictionshas been enhanced to integrate the clustering feature. Clustering requires several layers to be prepared and configured:

This guide describes the steps required to setup Joget LEE clustering. The exact steps will depend on the actual products used in each layer.

1. Deploy the WAR file jw.war from the LEE Joget installation bundle to each of the application servers e.g. for Apache Tomcat, copy the files into the webapps directory

   将WAR文件jw.war和jwdesigner.war从LEE包中部署到每个应用服务器，例如Apache Tomcat，将这些文件复制到tomcat webapps目录

   Thai
   ปรับใช้ไฟล์ WAR jw.war และ jwdesigner.war จากแพ็คเกจ LEE ไปยังแต่ละเซิร์ฟเวอร์แอปพลิเคชันเช่น Apache Tomcat และคัดลอกไฟล์เหล่านี้ไปยังไดเรกทอรี tomcat webapps

2. Add the following Java options in the application server startup e.g. for Apache Tomcat, modify the JAVA_OPTS lineFor Joget DX 8, the wflow-cluster.jar file is already included and configured in the default startup script. Modify the JAVA_OPTS in the startup script if necessary (particularly regarding the shared directory path).

   Chinese
   在应用程序服务器启动中添加Java -wflow.home = shared_directory_path选项，例如，对于Apache Tomcat，请修改JAVA_OPTS行

   Thai
   เพิ่มตัวเลือก Java ต่อไปนี้ในแอปพลิเคชันเซิร์ฟเวอร์เริ่มต้นเช่น สำหรับ Apache Tomcat ให้แก้ไขบรรทัด JAVA_OPTS

   Note: You can download the wflow-cluster.jar from here. The "wflow-cluster.jar" option must be added before any other "-javaagent" option.
   

export JAVA_OPTS="-Xmx1024M -Dwflow.home=/shared_directory_path -javaagent:/shared_directory_path/wflow-cluster.jar -javaagent:/path_to/lib/aspectjweaver-1.89.57.jar -javaagent:/shared_directory_path/glowroot/glowroot.jar"
