JVMTI 提示和技巧
我想做的是将quartz 的功能与jvmti 结合起来。基本上，我的计划是使用 jvmti 来监视内存使用情况，并在此基础上我将根据使用quartz 的优先级在 que 上启动/执行进程。我希望每个进程都以 this-process-will-execute-this-amount-of-timeslice 方法完成，以防止无响应，并能够处理所有传入的 java 进程，如 Web 请求。
我还没有在任何地方找到这个主题的教程（我能找到的教程很少，但对于像我这样的菜鸟来说还不够），这是 C 编程和 Java 编程的结合。我现在拥有的是带有c/c++插件的netbeans ide，虽然我还没有完成mingw的安装，但我想我可以处理这个问题，还有来自orasun的jvmti参考资料。
你们能指导我该怎么做吗？工具？参考资料？我可以查看/结帐现有的类似项目吗？我只是想加快这一速度，如果这里有人有类似的经历，会分享她/他的经历。
干杯！
what i want to do is to combine the power of quartz with jvmti. basically, my plan is to use jvmti to monitor memory usage and base on that i will launch / execute process on que depending on its priority using quartz. i want each process to be done in a this-process-will-execute-this-amount-of-timeslice approach to prevent non responsiveness and be able to handle all the incoming java processes like web request.
i havent found a tutorial in this topic anywhere (there are minimal that i can find but not enough for a noob like me), this is a combination of c programming and java programming. what i have at the moment is netbeans ide with c/c++ plugin, though i am not done yet with mingw installation but i think i can handle this and also a reference material of jvmti from orasun.
can you guys guide me on what to do? tools? reference materials? existing similar projects that i can look / checkout with? i just want to speedup this one and if someone here has this similar experience, would share her / his experiences.
cheers!

当我继续编写 jvmti 代理的旅程时，我遇到了这个问题：
提示显示“找不到 Agent_OnLoad”。我用谷歌搜索线索（我总是这样做）并找到了一些我必须链接在一起的信息，结果是在构建代理 dll 时应该出现的参数（我正在使用 Windows 操作系统、netbeans IDE、mingw、msys）
我应该添加这一行：
-D_JNI_IMPLMENTATION_ -g -fno-strict-aliasing -fno-omit-frame-pointer -W -Wall -Wno-unused -Wno-parentheses -我。 - 共享
到项目属性（右键单击）>构建> c 和 c++ 编译器 >其他选项
我的命令行如下所示：
gcc -D_JNI_IMPLMENTATION_ -g -fno-strict-aliasing -fno-omit-frame-pointer -W -Wall -Wno-unused -Wno-parentheses -I。 -shared -shared -o dist/Debug/MinGW-Windows/libjvmticallbackc.dll build/Debug/MinGW-Windows/jvmticallbackc.o -L../../jdk.1.7.0/lib -ljawt -ljvm
我只是想我应该分享我发现的东西。
as i continue my journey on writing jvmti agents, i bumped into this problem:
the prompt says "cannot find Agent_OnLoad". i googled for the clues ( i always does) and found pieces of information that i have to linked together, the result is a parameter that should be present upon building the agent dll (i am using windows OS, netbeans IDE, mingw, msys)
i should add this line:
-D_JNI_IMPLEMENTATION_ -g -fno-strict-aliasing -fno-omit-frame-pointer -W -Wall -Wno-unused -Wno-parentheses -I. -shared
to project properties (right click) > build > c and c++ compiler > additional options
my command line looks like this:
gcc -D_JNI_IMPLEMENTATION_ -g -fno-strict-aliasing -fno-omit-frame-pointer -W -Wall -Wno-unused -Wno-parentheses -I. -shared -shared -o dist/Debug/MinGW-Windows/libjvmticallbackc.dll build/Debug/MinGW-Windows/jvmticallbackc.o -L../../jdk.1.7.0/lib -ljawt -ljvm
i just thought i should share what i find.
