安装了64位 jdk7_17之后，tomcat 7 总是报内存溢出错误。

调整之后依然不起作用，不得已又换回32位JDK。

调整内存的配置：

export JAVA_OPTS="-server -Xmx1536M -XX:MaxPermSize=512m -Dfile.encoding=UTF-8"

保存为%TOMCAT_HOME%/bin/setenv.bat

参数说明：

-server

Select the Java HotSpot Server VM.

-Xmxn
    Specify the maximum size, in bytes, of the memory allocation pool. This value must a multiple of 1024 greater than 2MB. Append the letter k or K to indicate kilobytes, or m or M to indicate megabytes. The default value is 64MB. Examples:

               -Xmx83886080
               -Xmx81920k
               -Xmx80m

-XX:MaxPermSize=64m
    Size of the Permanent Generation. [5.0 and newer: 64 bit VMs are scaled 30% larger; 1.4 amd64: 96m; 1.3.1 -client: 32m.]

-Dproperty=value
    Set a system property value. If value is a string that contains spaces, you must enclose the string in double quotes:

                java -Dfoo="some string" SomeClass
