windows服务启动tomcat内存溢出问题解决方案

利用程序修改注册表，代码如下

 void UpdateMemmory() 

        {

            try

            {

                RegistryKey root = Registry.LocalMachine;

                RegistryKey software = root.OpenSubKey("SOFTWARE", true);

                RegistryKey asf = software.OpenSubKey("Apache Software Foundation", true);

                RegistryKey pru = asf.OpenSubKey("Procrun 2.0", true);

                //RegistryKey tl = pru.OpenSubKey("tomcatloan", true);

                RegistryKey tl = pru.OpenSubKey(CommonMethod.GetTomcatName(), true);

                RegistryKey Parameters = tl.OpenSubKey("Parameters", true);

                RegistryKey java = Parameters.OpenSubKey("Java", true);

                string[] strarray = java.GetValue("Options") as string[];

                if (strarray != null)

                {

                    bool flag = true;

                    ArrayList al = new ArrayList();

                    for (int i = 0; i < strarray.Length; i++)

                    {

                        //if (strarray[i] == "-Xrs –Xms512m –Xmx1024m")

                        if(strarray[i].StartsWith("-Xrs –Xms512m –Xmx1024m"))

                        {

                            flag = false;

                        }

                        al.Add(strarray[i]);

                    }

                    if (flag)

                    {

                        al.Add("-Xrs –Xms512m –Xmx1024m");

                        al.Add("-XX:PermSize=256M");

                        al.Add("-XX:MaxPermSize=256M");

                        java.SetValue("Options", (string[])al.ToArray(typeof(string)), RegistryValueKind.MultiString);

                    }

                }

            }

            catch 

            {

                

            }

        }

  al.Add("-XX:PermSize=256M");
   al.Add("-XX:MaxPermSize=256M");

上边这两句很重要，是设置tomcat的非堆内存大小，什么事非堆内存，自己可以百度。同时写进注册表的参数一定是分行的，写成一行不行。
