On Weblogic 12c you have two different situations:

1) Updating the JDK Location in an Existing Oracle Home

2) Updating the JDK Location in an Existing Domain Home

You could do the following steps: To update the JDK location in the .globalEnv.properties file: Use the getProperty.sh|cmd script to display the path of the current JDK from the JAVA_HOME variable. For example:

(UNIX) ORACLE_HOME/oui/bin/getProperty.sh JAVA_HOME
(Windows)  ORACLE_HOME\oui\bin\getProperty.cmd JAVA_HOME
echo JAVA_HOME

Where JAVA_HOME is the variable in the .globalEnv.properties file that contains the location of the JDK.

Back up the path of the current JDK to another variable such as OLD_JAVA_HOME in the .globalEnv.properties file by entering the following commands: (UNIX) ORACLE_HOME/oui/bin/setProperty.sh -name OLD_JAVA_HOME -value specify_the_path_of_current_JDK (Windows) ORACLE_HOME\\oui\\bin\\setProperty.cmd -name OLD_JAVA_HOME -value specify_the_path_of_current_JDK

This command creates a new variable called OLD_JAVA_HOME in the .globalEnv.properties file, with a value that you have specified. Set the new location of the JDK in the JAVA_HOME variable of the .globalEnv.properties file, by entering the following commands:

(UNIX) ORACLE_HOME/oui/bin/setProperty.sh -name JAVA_HOME -value specify_the_location_of_new_JDK
(Windows) ORACLE_HOME\oui\bin\setProperty.cmd -name JAVA_HOME -value 

specify_the_location_of_new_JDK

After you run this command, the JAVA_HOME variable in the .globalEnv.properties file now contains the path to the new JDK, such as jdk1.8.0_131.
