[转载]java.net.SocketException: Too many open files 有关问题的解决
[转载]java.net.SocketException: Too many open files 问题的解决
今天一个应用日志显示异常：java.net.SocketException: Too many open files这是因为网络请求过多，也就导致了系统打开的文件过多。每一个连接都会当成“文件”看待的。于是用命令ulimit -a（效果：查看每个用户允许打开的最大文件数）看到最大文件数是1024，将其更改大点，如ulimit -n 4096然后必须重启下网络服务，我用的是WebLogic，重启之后便没有出现异常。导致 Too many open files ，网络请求过多是一种可能，但也有可能是程序上的缺陷，如没有释放一些文件句柄，程序open了文件却忘记了在最后close。但我确信工程中没有用到打开文件这一环节，因此这个可能是排除掉了。用lsof -p [进程ID] 可以看到某ID的打开文件状况。进程ID可能用 ps -ef|grep java列出weblogic的进程ID，然后用此ID套入lsof -p ID号，咳，一大堆的请求哟，这显然是网络请求过多造成了 Too many open files。适当调整后便已消除这种现象----查看当前进程打开了多少句柄数lsof -n|awk '{print $2}'|sort|uniq -c|sort -nr|more
21 3359其中第一列是打开的句柄数，第二列是进程ID。
关于javascript自动计算的有关问题
关于javascript自动计算的问题我做的一个表包含有自动计算,就是左边的值改变后,右边等号后面的值根据左边的值自动计算,这个功能实现了,但是右边表单计算必须在左边表单点击后才能计算出值,比如左边的第一行的第一个表单的值是5,当点击这个表单后等号后面自动计算出是5
,可不可以不点就得出值,就好比直接打开网业,右边的值就根据左边自动计算,请高手们帮忙解决.

------解决方案--------------------window.onload = function startCalc(){
interval = setInterval( "calc() ",1); //上面的代码要先通过这个方法算出第三文本框的值
interval2 = setInterval( "sum() ",1)　//sum()函数只是计算所有第三文本框的总和
　//这样才能得到你想要的结果
