environment (JRE) bundled with the installation program and an uncompressed copy of the JRE
that is expanded into the temporary directory. The extracted files are deleted from the temporary
directory at the end of the installation process. As a general rule, installation programs require
approximately 2.5 times the amount of temporary space that is ultimately required by the installed
files.
By default, the installation program uses the following temporary directories:
z Windows platforms—directory referenced by the TMP system variable
z UNIX platforms—system-dependent temporary directory
Note: If you do not have enough temporary space to run the installation program, you are
prompted to specify an alternate directory or exit the installation program.
To make sure that you have adequate temporary space, you may want to allocate an alternate
directory for this purpose. To do so, follow the instructions provided in the following table.

Platform Perform this step . . .
Windows Do one of the following:
• Set the TMP system variable to a directory of your choice.
• If starting the installation program from the command line, include the
-Djava.io.tmpdir=tmpdirpath option, replacing tmpdirpath
with the full path of the directory that you want to designate as a
temporary storage area for the BEA Products installation program. For
example:
platform920_win32.exe -mode=console
-Djava.io.tmpdir=D:\Temp
UNIX Enter the following option on the command line when you start the
installation program:
-Djava.io.tmpdir=tmpdirpath
Here, tmpdirpath is the full path of the directory that you want to
designate as a temporary storage area for the BEA Products installation
program.
