upgrade weblogic server from 12cr1 to 12cr2 - weblogic12c

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.

Answer 3

use the following command:
C:\Softwares\Weblogic12c> "\Program Files\Java\jdk1.7.0_05\bin"\java
-jar fmw_12.2.1.0.0_wls.jar
C:\Softwares\Weblogic12c> is the location of my weblogic jar file.
"\Program Files\Java\jdk1.7.0_05\bin"\ is the location of my jdk.

Answer 4

It may happen that the jar is not taking the JAVA_HOME or PATH variables that may be set in the environment variables. In this case you may set it manually in the cmd. GOTO Run->cmd.
Then goto the folder where you have placed your jar
C:\Users\User\Downloads>set JAVA_HOME=C:\Program Files\...\jdk1.8.0_112
C:\Users\User\Downloads>set PATH=C:\Program Files\...\jdk1.8.0_112\bin;%PATH%
and then you may go on executing the jar,
C:\Users\User\Downloads>java -jar wls_121200.jar
It worked for me! Hope it helps. Thanks.

Answer 5

Run as Administrator the Command Prompt
Open the Weblogic's jar directory
Execute the java -jar command over the jar file:
From Runtime Variable (Make sure you have it set)
java -jar wls_121200.jar
From sepecific directory
"C:\Program Files\Java\jdk1.7.0_79\bin\java.exe" -jar wls_121200.jar
