Jboss 优化配置 一．??????? Jboss后台启动：添加后台修改命令： vi run.shwhile 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 doesnt work, check you are running JBossAS 4.0.4+?? #??? /jira/browse/JBAS-2483?? # or the following if youre running Red Hat 7.0?? #??? /de ... e/bugs/4465334.html?? ?? if [ $JBOSS_STATUS -eq 10 ]; then????? echo Restarting JBoss...?? else????? exit $JBOSS_STATUS?? fidone 二．??????? Jboss内存优化：修改这个两参数，给jvm分配适当的内存，一般为服务器的3/4内存量，推荐至少使用4G内存。另外添加两个参数 -XX:+UseParallelGC -XX:+UseParallelOldGC 这两个让服务并行回收内存空间。修改完成后，大致为 JAVA_OPTS = “-Xms4096m -Xmx8192m -XX:+UseParallelGC -XX:+UseParallelOldGC -Dsum…… 三．??????? Jboss日志输出模式[root@190MEM conf]# pwd/usr/local/jboss/server/default/conf[root@190MEM conf]# vi jboss-log4j.xml?? appender name=FILE class=org.jboss.logging.appender.DailyRollingFileAppender????? errorHandler class=org.jboss.logging.util.OnlyOnceErrorHandler/????? param name=File value=${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：datasourceslo
