Verify and Fix Environment Variables

Check values and correct them, if required, as mentioned below:

• Check Values
  
• Correct Values
  

Check Values

To check variable values:

1. Open a DOS prompt window.

2. Run:

   ORACLE_HOME\user_projects\domains\OPADomain\bin\setDomainEnv.cmd
   

   For example:

   C:\Oracle\Middleware\Oracle_Home\user_projects\domains\OPADomain\bin\setDomianEnv.cmd
   

   The script should run with no errors.

3. Inspect the value of JAVA_HOME:

   1. At the DOS command prompt, type: set JAVA_HOME. You should see the location where you installed JDK following instructions in Install Oracle Java Development Kit.

   2. Enter: dir %java_home%. You should see the directory specified as your JAVA_HOME containing a file called src.zip and four subdirectories: jre, lib, bin, and include.

      If you do not see these things, you will need to add them as directed in Correct Values.

      If JAVA_HOME contains any spaces or if any of the directories in its path are greater than 8 characters, you will need to correct them as directed in Correct Values.

4. Inspect the value of JAVA_VM. At the command prompt, enter: set JAVA_VM. You should see something like JAVA_VM=-server. If not, correct as directed in Correct Values.

Correct Values

To correct any of the above problems:

1. Navigate to ORACLE_HOME\oracle_common\common\bin.
2. Back up commEnv.cmd.
3. Open commEnv.cmd in a text editor.
4. The first set command in the file, before any other set command, must identify the JAVA_HOME value. For example:

   set JAVA_HOME=c:\app\java\jdk

5. Find:

   set JAVA_VM=-client

   change it to:

   set JAVA_VM=-server

6. Close the DOS window and open a new one, then repeat the steps in Check Values.
