How to find Weblogic server version information







6 Ways to get Oracle WebLogic Server Version information




You may check WebLogic Version by various ways that depends on your convenience and access provided to you.


First of all I would like to tell the easiest method to get this done by Console
(May be you think it is not challenging to you… go down to get actual one ……………………  J J )



In bottom left of the console login page you will get version info of WebLogic installed.






 












If you don’t have access to Console of WebLogic then use following points to get version details


Method: 1)   From registry.xml available under the MW_HOME (middleware home)

Path: - $MW_HOME/registry.xml

You may open this file and search the XML element <component name=”Weblogic Server” version=”12.1.1.0” ……          …….             …..>

Here version is “12.1.1.0” is given.



 Method: 2)   From Admin Server log file, you may get the detail of installed WebLogic version

Path: - $Domain_HOME/server/AdminServer/logs/AdminServer.log

In AdminServer.log file you may get WebLogic Server version details as it is printed once server is started.



Method: 3) By Java class weblogic.version

Path: - $WL_HOME/server/lib

Here you will get weblogic.jar file. By using below command you will get version info

$ java –cp weblogic.jar weblogic.version

You will see below output :-

WebLogic Server 12.1.1.0  Fri Feb 17 20:47:33 PST 2015 1384255
Use ‘weblogic.version -verbose’ to get subsystem information


Method: 4) you may look for Config.xml file available under domain home in WebLogic installation.

Path: - $Domain_HOME/config/config.xml



Method: 5) Using command line :-

$ java weblogic.version

For more detail or subsystem details –

$ java weblogic.version -verboose


Note: - if above commands will not work and you get Error : No class found or could not load…..
Then you have set JAVA_HOME to JRockit or BEA Java Not the OS provided or installed.

You may check which Java you are using on box by following command:-

$ which java

If you get OS installed java then use method-3.



Method: 6) Using WLST script to get WebLogic version: -


Path to invoke WLST prompt: -  $ ML_HOME/wl_server_x.x.x/common/bin/wlst.sh

Wlst/offline> version
