位于对象等待池中的阻塞状态(Blocked in object’s wait pool): 当线程处于运行状态时,如果执行了某个对象的 wait()方法,Java 虚拟机就会把 线程放到这个对象的等待池中,这涉及到“线程通信”的内容。 位于对象锁池中的阻塞状态(Blocked in object’s lock pool): 当线程处于运行状态时,试图获得某个对象的同步...
Verify that the Java process is still running with theps auxcommand (RorSstate inSTATcolumn) . For example,jstack -F <pid>puts the target Java process in a "trace stop" (T) state. Threads in the (T) state will receive the signal for a thread dump; however, output will be delayed ...

> /opt/tmp/threadDump.txtAs per the example thread dump of the process would be generated in /opt/tmp/threadDump.txt file.eg.9. Linux查看java进程耗CPU比较高的问题，常用命令和步骤：1）用 top 看看是否 java 进程占用 CPU 高，如果是 ，执行命令 top -p pid -H （记得替换 pid）2）抓 dump ...
jcmd:execute jcmd command 对于在没有JDK环境,但是有JRE环境时,想要做heap dump就无法直接使用jmap,或者jstack做thread dump,这时可以引入jattch,jattach为一个可执行的二进制文件,不需要额外的配置和依赖就可以如jmap,jstack那样实现dump。 jattach相关介绍,jattach 源码。其具体实现原理是调用了Hotspot JVM的Dynamic At...
Runningjstackwith the IDE PID will print the thread dump into console, however it's not very convenient. Use this command to redirect the output to a file: jstack-l<PID>>dump.txt To take several dumps repeat this command with different file names, like dump1.txt, du...
