java - 错误 : Cannot load this JVM TI agent twice starting Oracle WebLogic Server 12. 1.3.0

Question

我正在启动 Oracle WebLogic Server 12.1.3.0，我在其中托管了一些 WEb 应用程序，但我无法启动它，因为出现错误

用Java版本回显启动weblogic:

%JAVA_HOME%\bin\java %JAVA_VM% -version

if "%WLS_REDIRECT_LOG%"=="" (
    echo Starting WLS with line:
    echo %JAVA_HOME%\bin\java %JAVA_VM% %MEM_ARGS% -Dweblogic.Name=%SERVER_NAME% -Djava.security.policy=%WLS_POLICY_FILE% %JAVA_OPTIONS% %PROXY_SETTINGS% %SERVER_CLASS%
    %JAVA_HOME%\bin\java %JAVA_VM% %MEM_ARGS% -Dweblogic.Name=%SERVER_NAME% -Djava.security.policy=%WLS_POLICY_FILE% %JAVA_OPTIONS% %PROXY_SETTINGS% %SERVER_CLASS%
) else (
    echo Redirecting output from WLS window to %WLS_REDIRECT_LOG%
    %JAVA_HOME%\bin\java %JAVA_VM% %MEM_ARGS% -Dweblogic.Name=%SERVER_NAME% -Djava.security.policy=%WLS_POLICY_FILE% %JAVA_OPTIONS% %PROXY_SETTINGS% %SERVER_CLASS%  >"%WLS_REDIRECT_LOG%" 2>&1 
)

但是我得到了这个错误:

Answer 1

您是否已阅读错误消息？特别是对于这部分“检查您的 java 命令行是否有重复的 jdwp”。那么你可能已经发现-Xrunjdwp在启动命令中出现了两次(下面一行:“Starting WLS with line”)。

因此，您需要检查在启动配置中设置了 %JAVA_OPTIONS% 和 %PROXY_SETTINGS% 的值。我猜 -Xrunjdwp 被附加到 %JAVA_OPTIONS% 两次(除非有人误用了 %PROXY_SETTINGS%)。
