Its in infodoc 10012, which you can access if you have a valid account on Sunsolve which is linked to a service account.
Anyway, for the ancient 2.6, the support ends on 07/23/06, no new patches have been produced for it for a couple of years, so this only means that sun won't give support on it, nor have to give you access to old patches.
7/M.
Another procedure that has worked well for me over the years.
Go to Sun's web page.
http://www,sun.com
In the top corner of the web page, there is a search area.
Put in keyword eosl (for "end of support life").
The search results will bring up most every topic related
to Sun's philosophies and policies on the subject.More than you'd ever choose to read.
As an example, there were more than 225 search results today.

Keyword eol (for "end of life") is also a valid search word,
but produces more than 1500 search results.
