Oracle Linux FAQ:
 Linux is a free operating system, is Oracle for Linux also free?
Linux is a free Operating System and hence people expect Oracle on Linux to also be free as well. However, this is not necessarily the case. If you need something that is free of charge, consider the following options:
- A free trial version of Oracle for Linux (the commercial version) can be downloaded from the Oracle Technology Network (OTN) web site. Please go to technet.oracle.com for details.
- Download Oracle XE (Express Edition). XE is a freeby, downloadable version of the Oracle database server that can be used on single processor machines. It can only manage up to 4 GB of data and 1 GB of memory.
For current pricing information, please check the Oracle Store website at store.oracle.com.
 What support is available for Oracle on Linux?
If you run on Oracle Enterprise Linux, you can also get Oracle to support the operating system. Contact your sales representative for more information.
