Installation Considerations
Oracle recommends the following:
Do not include spaces in the name of your Oracle home directory; the installer will give you an error message if your Oracle home directory path contains spaces.
You can install only one instance of each version of an Oracle WebLogic product in a single Oracle home directory
If you launch the installation from the command line or from a script, you can specify the -log option to generate a verbose installation log. The installation log stores messages (informational, warning, error, and fatal) about events that occur during the installation process.
