upgrade weblogic server from 12cr1 to 12cr2

Question

I need to know how can i upgrade my Weblogic application server from release 1 to release 2. My OS is windows 7 64 bit. I am new to this some one else installed weblogic so i tried to install it by myself but it is giving me error

C:\Users\User\Downloads>java -D64 -jar wls_121200.jar Extracting files................................................................ .................................... This installer must be executed using a Java Development Kit (JDK) but C:\Program Files\Java\jre7 is not a valid JDK. The Oracle Universal Installer failed. Exiting.

so i unzipped the jar with 7 zip now intaller has started is it the correct way?

Answer 1

Using command prompt, navigate to the directory where you downloaded the installation program.

Launch the installation program by invoking java -jar from the JDK directory on your system,

as shown in the example below:

\home\Oracle\jdk7_15\jdk1.7.0_15\bin\java -jar wls_121200.jar -- sure to replace \home\Oracle\jdk7_15\jdk1.7.0_15 -- in this example with the location of the JDK on your system

Answer 2

The only thing you need is to execute the installer using the jdk needed for it. for example:

"C:\Program Files\Java\jdk1.7.0_79\bin\java.exe" -jar wls_121200.jar

I used the java.exe from my jdk 7 folder instead of the java installed on my computer.

The weblogic jar folder doesn't matter.
