Note:

Note while creating  the Middleware home directory:

  • Do not include spaces in the name of your Middleware home directory otherwise the CLASSPATH may not be resolved properly.
  •  You can install only one instance of each version of a WebLogic Server product in a single Middleware home directory. For example, you can install only one instance of the current version of WebLogic Server in a Middleware home directory, but you can have an earlier version of WebLogic Server in a separate Middleware home directory.
  • If the home directory is not empty and it does not contain registry.xml, or if any of the product installation directories are not empty, one of the following messages is displayed:

For home directory selection task—Middleware home directory is not empty. Proceed with installation?

For product installation directory selection task—One or more installation directories are not empty. Proceed with installation?
