[confluence] JVM memory adjustment

background ：Confluence 7.16.2 Data Center edition , The default installation is JVM Memory set to 1024M, When the number of simultaneous access users is large , The service is stuck , Journal JVM OutOfMemoryError.

Problem solving ： modify Confluence The configuration file , increase JVM Memory .

step ：

1） stop it Confluence service

2） modify Confluence The configuration file

 modify  CATALINA_OPTS="-Xms1024m -Xmx1024m ${CATALINA_OPTS}"
 by    CATALINA_OPTS="-Xms8g -Xmx8g ${CATALINA_OPTS}"

explain ：

•  -Xms：Java Heap Maximum , The default is physical memory 1/4, The best setting depends on the size of the physical memory and other memory overhead in the computer
• -Xmx：Java Heap Initial value ,Server End JVM It is best to -Xms and -Xmx Set to the same value , Develop a test machine JVM You can keep the default value

3） start-up Confluence service

[[email protected] ~]# cd /data/atlassian/confluence/bin [[email protected] bin]# ./startup.sh
