如何在websphere中手动生成javacore文件

在命令行中操作
进入wsadmin

D:\IBM\WebSphere\AppServer\profiles\AppSrv01\bin>wsadmin -user wasadmin -password password

设置jvm环境变量

wsadmin>set jvm [$AdminControl completeObjectName type=JVM,process=server1,*]

生成javacore文件

wsadmin>$AdminControl invoke $jvm dumpThreads

找到JVM对象名字

wsadmin>set objectName [$AdminControl queryNames WebSphere:type=JVM,process=server1,*]

生成heapdump文件

wsadmin>$AdminControl invoke $objectName generateHeapDump




利用wsadmin生成javacore,heapdump文件
一、生成javacore文件

安装目录WebSphere\AppServer\bin\wsadmin.bat
输入命令  wsadmin>set jvm [$AdminControl completeObjectName type=JVM,process=server1,*]          
输入命令  wsadmin>$AdminControl invoke $jvm dumpThreads
安装目录\WebSphere\AppServer\profiles\default下生成javacore文件(例:javacore.20090804.111947.2632.txt)
用javacore文件分析器对javacore文件进行分析
cd /d javacore文件分析器放置路径>java –Xmx1000m –jar jca31.jar


二、生成heapdump文件

安装目录WebSphere\AppServer\bin\wsadmin.bat
输入命令  wsadmin>set objectName [$AdminControl queryNames WebSphere:type=JVM,process=server1,*]
输入命令  wsadmin>
$AdminControl invoke $objectName generateHeapDump
安装目录\WebSphere\AppServer\profiles\default下生成HeapDump文件(例:heapdump.20090804.113353.2632.phd)
用heapdump文件分析器对heapdump文件进行分析
cd /d heapdump文件分析器放置路径>java –Xmx1000m –jar ha33.jar
