How to change JAVA_HOME for application deployed in WAS 8.5 base edition windows platform?

  • 1.  How to change JAVA_HOME for application deployed in WAS 8.5 base edition windows platform?

    Posted Sun May 17, 2015 05:30 AM

    Hi,


    I am using WAS 8.5 base edition on windows platform and I wish to have JAVA_HOME changed for application installed on the JVM.



    Currently the app is using JAVA_HOME as “D:\Program Files (x86)\IBM\WebSphere\AppServer\java” while we want the app to use JAVA_HOME which is “D:\IBM\EMM\Platform\jre\bin\java”



    How can I get it done?


    Kindly provide me with suggestions.



    Thanks,


    Kushal

    Hi Kushal,

      I'm not sure if you can use another than provided by WebSphere.
     
      You have several scripts related to manageSDK that are pointing to WAS_HOME\java o WAS_HOME\java_1.7_64 so if you change JAVA_HOME you can have unknown issues.
     
      You can try to change from Admin Console JAVA_HOME environment variable but you have the same environment variable inside several scripts in WAS_HOME\bin
     
      Why do you want to use other java than WAS_HOME\java?
     
    Regards

    set JAVA_HOME ="" in setupCmdLine.bat

    or

    Set as environment variable if the server is running in windows box.

    check in systemout/startserver.logs if the required JVM path which you wanted is loaded. 

    Its not recommended for IBM WAS to use other out of box JDK's
