1、weblogic816
C:\Documents and Settings\tony>java -cp E:\bea816\weblogic81\server\lib\weblogic.jar weblogic.Admin -url localhost:7001 -username weblogic -password weblogic THREAD_DUMP
Thread Dump has been printed to the servers standard out (by default, the shell
in which the server is running).
可以看到打印成功！
但是在9版本并不能使用该方法
2、weblogic923
启动server,打开wlst.cmd
连接到启动的AdminServer
Connect(‘weblogic’,’weblogic’,’t3://127.0.0.1:7001’)
threadDump()
可以看到写到了一个叫Thread_Dump_AdminServer.txt的文件里。
再次运行threadDump(),将会覆盖该文件。
因为目前是只启动了一个server,所以在进行dump的时候并没指定server，默认就对admin做了dump.
再启动一个server1.现在再次用不指定server的threadDump()仍旧只会产生admin的dump.
利用help命令，发现还有一个指定server的dump方法。
注意里面有个属性是是否写到文件，我这里是true.所以生成了dump文件.
3、weblogic10.0 for solarisx86
在soalris10上(weblogic10.0)操作wlst工具来进行线程堆栈成功。
wls:/mydomain/serverConfig> threadDump(writeToFile=’true’, fileName=’/opt/bea10/threaddump1.txt’)
