I wanted to upgrade the JDK version of my WebLogic server (10.3.6) from 1.7 to 1.8. What can be the possible steps required to do this?

I have existing weblogic and JDK old versions on Windows platform. I want to update them. But when I search document about update steps on internet, I couldn't find anything. They just mention about installing process.

As you want to update weblogic and jdk version 1.7 to 1.8,

  1. Then you can uninstall both of them.

  2. Then download weblogic 12.2.1 and jdk 8 from following link.

    Weblogic download link: weblogic download from here

    JDK8 download link: jdk 8 download from here

  3. Then install JDK8 first and then weblogic. Hope it is easy.

From Oracle blogs documentation,

  • WebLogic 12.2.1 requires Java 8 (JDK 8) as a runtime.
  • WebLogic 12.1.3 can be used with Java 7 or Java 8. Using WebLogic 12.1.3 with Java 7 caused warnings because of the permspace settings in the WebLogic start scripts. Permspace is removed from JDK 8, so also these warnings are gone now with WebLogic 12.2.1 and JDK8.
  • JDK 8 comes with Nashorn JavaScript engine. Try the jjs command line tool. Read the complete article here.

I thought the support for Java 1.8 has begun with WLS 12.1.3. So I assume its not possible/realistic to get wls10.x.x work with a newer jdk as 1.7.x.
