ERROR: Cannot load this JVM TI agent twice starting Oracle WebLogic Server 12.1.3.0

Question

I am starting Oracle WebLogic Server 12.1.3.0 where I have hosted some WEb applications, but I can not start it because I have an error

echo starting weblogic with Java version:

%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 
)

but i got this error:

ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate jdwp options.
Error occurred during initialization of VM
agent library failed to init: jdwp

Answer 1

Have you read the error message? Especially for this part "check your java command line for duplicate jdwp". Then you might have found that -Xrunjdwp is twice in the startup command (the line below: "Starting WLS with line").

So you need to check where the values for %JAVA_OPTIONS% and %PROXY_SETTINGS% are set in your startup configuration. I guess -Xrunjdwp is appended twice to %JAVA_OPTIONS% (except someone has misused %PROXY_SETTINGS%).
