You should ensure that adequate disk space is available before installing the Oracle Endeca Server.
On Windows, the installation process requires a minimum of 400 MB in the system partition and 200 MB in the target partition. To avoid an "out of drive space" error during the installation process, you should allow the minimum of memory required on the system and target partitions.
The Windows installation process unpacks its .MSI installation file, and other temporary and log files, to a location on the system drive (typically the user's %TEMP% folder). These files add another 400MB during the installation. When the process completes the installation, it deletes the temporary files and frees the 400 MB space it consumed.
On Linux, the Oracle Endeca Server unpacks to approximately 430 MB. Because multiple versions may eventually be stored, a destination in a large disk partition is recommended.
