Oracle's Documentation (the Manuals) are available on-line, on CD-ROM and in hard-copy book format. These mediums are described below:
On-line documentation (Web)
Registration at OTN is immediate, free, and no longer required to view the manuals. However, registering and signing in enables some personalization features, such as your own Favourites page.
Unfortunately the Oracle manuals are copyrighted and we (OraFAQ) do not have permission to publish them on this site. It would be darn nice if they let us.
When you order Oracle Software, you will also receive a documentation CD that contains all the generic (platform neutral) documentation. For reference purposes, download this CD to your workstation or upload the content to a website so you and your team can access it.
The platform specific documentation (including the installations guide) normally ships with the installation media. Look under the "/doc" directory on the first product CD or DVD.
Hard copies of documentation may still exist for older Oracle products. However, documentation for newer products is only available in electronic format.
