我确实有个Jenkins的例子 被困在无尽的循环中 没有任何可见的活动
我能得到运行过程的 pid , 因此我如何生成一个可以用于错误报告的跟踪?
我跑在林克斯上。
尝试 < a href=>" "http://download.oracle.com/javase/ 1.5.0/docs/tooldocs/share/jstack.html" rel = "noreferr" >jstack 。 它会给你一份完整的列表, 列出你的线条正在做什么。 它只需要进程 Pid 。
使用线索倾弃。 通过 VM 连接并请求倾弃。 或者如果在 unix 上, kill -3pid 或进程控制台上的窗口Ctrl+Break 将会为您做到这一点。 倾弃将直接进入控制台。 您也可以使用 jstack 来丢弃一个倾弃 。
Ctrl/code> on linux (发送 SIGQUIT )
Ctrl+Break on window(在 MSVCRT 下发送 SIGBRIEAK )
在 *nix 中,通过按下 H < /code>, top 您可以看到线条。
然后,在 jps 中,你可以看到 pid ,同时铭记,如果进程是以特权启动的,那么你就必须使用 sudo 执行,例如 sudo 。
如果您将线索 ID 转换为十六进制, 那么您就可以将数据与 jstack pid 输出交叉 。
两种工具均在$JAVA_HOME/bin中。
看看""http://visualvm.java.net/" rel="no follow" >VivialVM 。它有许多很好的特征分析工具,你可以做一个线状垃圾堆。
