How to identify the installed Weblogic Server and JDK are 32bit or 64bit?

Question

Hi everyone,
I have a question ~
Both Weblogic Server and JAVA JDK are installed on the server already, but I only know the Weblogic Server is 10.3.4.0 and JAVA JDK version is 1.6.0_25.
I know the 64bit Weblogic Server installation file is a wlsXXXX_generic.jar package and 64bit JAVA JDK needed also.
But, since the Weblogic installed already, there are no such installation files on the Linux Server now.
I have tried the "java -version" for java version and check the Weblogic version from Weblogic console.
How to identify the installed Weblogic Server and JDK are 32bit or 64bit with Linux command? Or is there any way to check it?

What you can try to do is use WLST (or an MBean browser, such as JConsole or JRockit Mission Control) and connect to the adminserver.
For example when using WLST:
# set the environment by using setWLSEnv.sh (located in the ${WL_HOME}/server/bin directory).
# start WLST by using: java weblogic.WLST
# connect to the adminserver
connect('adminusername','adminpassword');
# change to the serverruntime environment
serverRuntime();
# show the attributes
ls();
# Here an attribute is shown called WebLogicVersion that shows the version of WebLogic
-r--   WeblogicVersion                              WebLogic Server 10.3.5.0  Fri Apr 1 20:20:06 PDT 2011 1398638
# Note that this does not show if is 32 bits or 64 bits to retrieve this information you have obtain the JVM version
# change the directory
cd('JVMRuntime/AdminServer');
# show the attributes
ls();
-r--   Version                                      R28.0.1-21-133393-1.6.0_20-20100512-2126-linux-x86_64
# when you have something like x86 at the you are running a 32 bit version, if you have something like x86_64 you are running a 64 bits versionAs mentioned above you can also retrieve this information by using a MBean browser.
