在linux 上面加jboss 内存的问题？？？
问题是我百度了下，都说在jboss/bin 下面的run.sh 或run.conf 里面加，但是我vi 进去后，不知道要加在哪里。。
run.sh 文件

不知道是在jboss 默认的基础上面改，还是说直接输入，下面的参数
AVA_OPTS="$JAVA_OPTS -Xms2048m -Xmx2048m -XX:PermSize=1024m -XX:MaxPermSize=1024m"
JAVA_OPTS="$JAVA_OPTS -Dprogram.name=$PROGNAME"
[解决办法]
JAVA_OPTS="$JAVA_OPTS -Xms2048m -Xmx2048m -XX:PermSize=1024m -XX:MaxPermSize=1024m"
JAVA_OPTS="$JAVA_OPTS -Dprogram.name=$PROGNAME"
把这个随便放在脚边的某一行上面就可以了，这个参数是叠加计算的。最好放在前面几行

关于你说的闰年差的话，你可以判断一下，如果哪年可以除以4，你就加上一天，当然也要看有没包含2月吧，误差有一些的，毕竟不是很严格的算法。
