Previous Database Release Software

Oracle Database 10.2 and 11.1 are no longer available for download. The software is available as a media or FTP request for those customers who own a valid Oracle Database product license for any edition. To request access to these releases, follow the instructions in Oracle Support Document 1071023.1 (Requesting Physical Shipment or Download URL for Software Media) from My Oracle Support. NOTE: for Oracle Database 10.2, you should request 10.2.0.1 even if you want to install a later patch set. Once you install 10.2.0.1 you can then apply any 10.2 patch set. Similarly, for 11.1 request 11.1.0.6 which must be applied before installing 11.1.0.7. Patch sets can be downloaded from the Patches and Updates tab on My Oracle Support.

When I go to

edelivery.oracle.com

and do a search with 10.2.0.5

I only get

Enterprise Manager Grid Control 10.2.0.5.0

Oracle 10g database is no longer available from any legal or public Oracle sources. You have to contact Oracle sales or support.

See e.g. this old thread

Also 10.2.0.x is not supported on Linux 6 - so likely getting hold of the media will be the easy part ;-)

Directly you cannot start 10g installation on rhel 6 , before install

Edit the "/etc/redhat-release" file replacing the current release information (Red Hat Enterprise Linux Server release 6 ) with the following:

redhat-4

After installation you can reset it back .(Its just for skipping installer version check skip)

Can you point to a doc where this is the supported method ?

Workaround #2: On Oracle Linux 5 and Red Hat Enterprise Linux 5, the installation will pass the operating system prerequisite checks if you change each Oracle Linux 5 and Red Hat Enterprise Linux 5 to Oracle Linux 4 and Red Hat Enterprise Linux 4 in the /etc/redhat-release file. Ensure that you replace the original values in the /etc/redhat-release file after the Oracle installation is complete.

From below oracle doc link

That applies to EL 5, but not EL 6. EL 6 is way too far ahead regarding software per-requisites. I'm not saying it cannot be done, but it is not supported and has a few other challenges. Perhaps in the case of the OP, the best way is to run 10g under EL 6 inside VirtualBox using OL 5.
