JBoss Setting

After the installation of JBoss, here is the know-how of its setting.

1) Heap size

$ sudo vim $JBOSS/bin/run.conf

JAVA_OPTS="-Xms128m -Xmx512m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"
=>
JAVA_OPTS="-Xms512m -Xmx768m -Dsun.rmi.dgc.client.gcInterval=3600000 -Dsun.rmi.dgc.server.gcInterval=3600000"

2) Port check

vim $JBOSS/server/default/deploy/jboss-web.deployer/server.xml

3) Transaction time out

vim $JBOSS/server/default/conf/jboss-service.xml

300
=>
150

4) Thread number

vim server/default/deploy/jboss-web.deployer/server.xml

maxThreads="250"
=>
maxThreads="200"

5) Log Output level by log4j

vim /opt/jboss-4.2.3.GA/server/default/conf/jboss-log4j.xml 
   <root>
     <priority value="WARN" />
      <appender-ref ref="CONSOLE"/>
      <appender-ref ref="FILE"/>
   </root>
