JBoss优化（摘取）,该如何解决_JBoss

JBoss优化（摘取）
一． Jboss后台启动：
添加后台修改命令：
vi run.sh
while true; do
  if [ "x$LAUNCH_JBOSS_IN_BACKGROUND" = "x" ]; then
  # Execute the JVM in the foreground
  nohup "$JAVA" $JAVA_OPTS \
  -Djava.endorsed.dirs="$JBOSS_ENDORSED_DIRS" \
  -classpath "$JBOSS_CLASSPATH" \
  org.jboss.Main "$@"
  JBOSS_STATUS=$?
  else
  # Execute the JVM in the background
  "$JAVA" $JAVA_OPTS \
  -Djava.endorsed.dirs="$JBOSS_ENDORSED_DIRS" \
  -classpath "$JBOSS_CLASSPATH" \
  org.jboss.Main "$@" &
  JBOSS_PID=$!
  # Trap common signals and relay them to the jboss process
  trap "kill -HUP $JBOSS_PID" HUP
  trap "kill -TERM $JBOSS_PID" INT
  trap "kill -QUIT $JBOSS_PID" QUIT
  trap "kill -PIPE $JBOSS_PID" PIPE
  trap "kill -TERM $JBOSS_PID" TERM
  # Wait until the background process exits
  WAIT_STATUS=0
  while [ "$WAIT_STATUS" -ne 127 ]; do
  JBOSS_STATUS=$WAIT_STATUS
  wait $JBOSS_PID 2>/dev/null
  WAIT_STATUS=$?
  done
  fi
  # If restart doesn't work, check you are running JBossAS 4.0.4+
  # http://jira.jboss.com/jira/browse/JBAS-2483
  # or the following if you're running Red Hat 7.0
  # http://developer.java.sun.com/developer/bugParade/bugs/4465334
  if [ $JBOSS_STATUS -eq 10 ]; then
  echo "Restarting JBoss..."
  else
  exit $JBOSS_STATUS
  fi
done &
二． Jboss内存优化：
修改这个两参数，给jvm分配适当的内存，一般为服务器的3/4内存量，推荐至少使用4G内存。
另外添加两个参数 -XX:+UseParallelGC -XX:+UseParallelOldGC 这两个让服务并行回收内存空间。修改完成后，大致为 JAVA_OPTS = “-Xms4096m -Xmx8192m -XX:+UseParallelGC -XX:+UseParallelOldGC -Dsum……
三． Jboss日志输出模式
[root@190MEM conf]# pwd
/usr/local/jboss/server/default/conf
[root@190MEM conf]# vi jboss-log4j.xml
  <appender name="FILE" class="org.jboss.logging.appender.DailyRollingFileAppender">
  <errorHandler class="org.jboss.logging.util.OnlyOnceErrorHandler"/>
  <param name="File" value="${jboss.server.log.dir}/server.log"/>
  <param name="Append" value="false"/>
  <param name="Threshold" value="ERROR"/>
四． Jboss数据库连接池优化
修改数据库连接池：
<datasources>
  <local-tx-datasource>
  <jndi-name>training_master_db</jndi-name> <connection-url>jdbc:mysql://211.100.192.128:3306/dts?useUnicode=true&characterEncoding=UTF-8</connection-url>
  <driver-class>com.mysql.jdbc.Driver</driver-class>
  <user-name>root</user-name>
  <password></password>
  <min-pool-size>100</min-pool-size>
  <max-pool-size>500</max-pool-size> <exception-sorter-class-name>org.jboss.resource.adapter.jdbc.vendor.MySQLExceptionSorter</exception-sorter-class-name>
