Eclipse 内存分析器 - 尝试获取堆转储时出错
我正在尝试使用 Eclipse 内存分析器工具 (MAT) 获取堆转储。我正在运行 Weblogic 10.3 应用程序服务器。它是安装了 32 位 Java 的 Windows XP 操作系统。当我尝试使用 MAT 获取正在运行 Weblogic 的进程的堆转储时，出现以下错误：
Error creating heap dump. jmap exit code = 1

I am trying to acquire heap dump using the Eclipse Memory Analyzer Tool (MAT). I have Weblogic 10.3 app server running. It's a windows XP OS with 32 bit Java installed. When I try to acquire heap dump using MAT for the process that's running Weblogic, I am getting the following error:

您可以尝试的一件事是使用 jmap 保存转储并在 MAT 中打开它。
使用
jps获取进程ID（pid）。One thing you could try is using
jmapto save the dump and open it in MAT.Use
jpsto get the process id (pid).我在 Windows 上遇到了同样的问题，我通过以管理员身份打开 cmd.exe 解决了。
I met the same problem on Windows, I solved by open
cmd.exeas Administrator.
