This is my screen.
How can i resolve this problem or how i switch my valid java version. I installed java 8 and i did enter this command that "alternatives --set java java 8 path file". But he don't run.

I just installed a fresh copy of weblogic server and OSB.
After the successful installation of weblogic 10.3.6 on the quick start screen I tried to configure domain. however the screen doesn't processed any further giving the error in the screenshot below.
Also, in eclipse, when i try to add the server, It prompts me to create a domain, but that doesn't work either.
The error am getting in the console is:
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
Java HotSpot(TM) 64-Bit Server VM warning: ignoring option
MaxPermSize=128m; support was removed in 8.0
Unrecognized VM option 'UseSpinning'
It looks like Java 8 is being picked up elsewhere on your system.
Check to see if you have Java 8 installed and look at you path environment variable.
That warning you are getting is from Java 8. 10.3.6 would use Java 5 or 6...
Does anyone know when SQuirreL the JDBC Client will support java-9?
At the moment I get an error that the version is not supported, It fails while testing the java version on the start-up script.
Does anyone know when a release for 9 will be out?
I commented out the version check within the squirrel-sql.bat.
#rem "%LOCAL_JAVA%" -cp "%SQUIRREL_SQL_HOME%\lib\versioncheck.jar" JavaVersionChecker 1.6 1.7 1.8
#rem if ErrorLevel 1 goto ExitForWrongJavaVersion
Put #rem in front of those two lines.
You could download the latest snapshot which has support for Java 9 but there is no support in the official release yet and if you do the workaround to get past the version check then the application can't be closed.
What I did was override the VM to version 8. In the install folder there are two files:
squirrel-sql.bat
squirrel-sql.sh
In the .bat file I looked for the following line and changed it to point to a Java 8 VM.
set "IZPACK_JAVA=%JAVA_HOME%"
In the .sh file I made a similar change on this line.
IZPACK_JAVA_HOME=C:\Program Files\Java\jre-9.0.1
Squirrel will try to startup with this IZPACK JAVA_HOME first so it overrides whatever the system JAVA_HOME is set to.
I downloaded the latest SqlSquirrel and still got the message. How I solved it was to add my current JDK version to squirrel-sql.bat, on the line where it checks versions...
"%LOCAL_JAVA%" -cp "%SQUIRREL_SQL_HOME%\lib\versioncheck.jar" JavaVersionChecker 1.8 9 10 11 12 13.0.2
In my case, I had to add 13.0.2.
When I try to start the the deployment manager in WebSphere Application Server I'm getting the following error:
00000001 SDKUtils
A ADML0004E: An exception occurred when attempting to expand variable $(JAVA_HOME) com.ibm.wsspi.runtime.variable.
UndefinedVariableException: Undefined variable JAVA_HOME
at com.ibm.ws.runtime.component.VariableMapImpl.expand(VariableMapImpl.j
First of all you cannot set third party Java SDK for traditional WebSphere Application Server. For WAS 8.5.5.x you can only select from IBM Java 6 and IBM Java 7 which must be downloaded from IBM and installed via Installation Manager. So don't play with JAVA_HOME variable manually.
Once you install Java 7 for WAS, you can use managesdk command line tool to switch Java for given profile and server.

Java 7.1 in IBM Websphere
managesdk command
since we can not start the deployment manger or default server, there is a way to solve this problem that is add the JAVA_HOME into varibles.xml file which is under server folder. path : Installserver/profile/config/node/cell/server
Please give some more information like OS, windows, or linux, or what.
If I understand correctly you'll use the jdk of the WAS installation elsewhere?
Under Windows set JAVA_HOME accordingly within the System environment properties. logout / login after this may be a good idea.
Under linux use: export JAVA_HOME=/opt/ibm/pathtoWAS/java
I would do this within .profile and maybe it's helpful to set the PATH to the jdk too!
I am facing strange issue with sonarqube 5.0.1 , one one of the machine it is not starting. Here is the error log - sonar.log -
--> Wrapper Started as Daemon
Launching a JVM...
Unable to start JVM: No such file or directory (2)
JVM exited while loading the application.
JVM Restarts disabled. Shutting down.
<-- Wrapper Stopped
Machine is x86_64 GNU/Linux - Centos 5.1.
this box has java installed -
$java -version
java version "1.6.0_45"
Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)
The same sonarqube package works on another machine.
Any idea what could be the issue here?
Thanks.
Issue was in the wrapper.conf where the java wrapper command was not getting resolved. It worked if I give the absolute path - ‘wrapper.java.command=/path/to/my/jdk/bin/java’
This could be an issue with an environment on a host.. not sure.
Few things that helped me in troubleshooting this -
log level changed to DEBUG in wrapper.conf
comments given in the wrapper.conf!
Thanks all for chiming in! Appreciate your inputs.
1.Just close all running jvm from task manager
2. Change the port of the sonar runner from the properties
I had the same symptoms (wrapper starts then immediately stops).
I tried these steps and finally succeeded (on a windows 10 pc):
1) in wrapper.conf, specified the java command:
wrapper.java.command=C:\Program Files\Java\jdk1.7...\bin\java.exe
That did not help.
2) Finally this fixed the problem. In the windows Services, open the Sonar service and then open Log On tab.
Changed the Log On to myself as follows:
I was facing the same issue on sonar startup. After reading this post , i modified the JDK path in below file and it works.
Modify the JDK path in wrapper.conf
wrapper.java.command=%JAVA_HOME%/bin/java
Install jdk 11
sudo yum install java-11-openjdk -y
sudo alternatives --config java
Select the JDK 11 version
Set the JDK 11 version in wrapper.conf
vi /opt/sonar/conf/wrapper.conf
wrapper.java.command=/usr/lib/jvm/java-11-openjdk-11.0.13.0.8-3.el8_5.x86_64/bin/java
Could you verify the Java version on the machine starting?
Java 6 is no more supported http://docs.sonarqube.org/display/SONAR/Requirements#Requirements-Prerequisite but from your error message, I don't know if this is the problem you meet.
Solution 1
Set java path globally
Solution 2
Go to sonarqube-{version}/conf directory
Edit wrapper.conf file
Replace wrapper.java.command=java with wrapper.java.command= {path-to-your-java-bin-directory}/java
eg: wrapper.java.command=/usr/java/bin/java
Try using a relative path, if your Sonar Folder is located in the same root folder as your jdk. For me my sonar and jdk are both under "Program Files", which has restrictive permission, hence the error.
E.g:
wrapper.java.command=../../../Java/jdk-11.0.4/bin/java
I am creating a Basic Weblogic server domain(11g, version 10.3.5.0 ). And in the JDK selection Window, in Available JDKs , ' JRockit SDK 1.7.0_55 # C:\Program Files\Java\jdk1.7.0_55' is selected..
The domain gets created, now i check the 'Start Admin Server' checkbox and click 'Done' . The process of starting server runs in the cmd, but it halts with the following error::
starting weblogic with Java version:
Unrecognized option: -jrockit
Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.
My Jdk(64-bit) is installed correctly according to me, JAVA_HOME and those things are correct. jrockit comes bundled with JDK , so why this error, any leads will be very helpful..
Thanks :)
I believe that WebLogic 10.3.5 only supports Suns Java JDK 1.6.0_24+ OR JRockit R28.1.3-1.6.0_24+.
It appears as though Weblogic 10.3.5 is not compatible with Java 7, try re-installing/configurring with a Java 6 version installed.
