Can someone guide me to a link where i can download older update for solaris 10 os i need solaris 10u4-6 . I couldn't find one on sun.com
You can only download the latest from Sun website. You need to source for the media from someone who has it. By the way, why do you need the older release? I suppose the new ones will be better. What's the requirement for?
I think I hava a image , if I do then I will upload it to somewhere 
if you have a sunsolve account (ie. registered access to thier download area) there are still versions of the older software available.
I've just checked and solaris 10 (06) is still available for download.
IF thats the case, provide us the link. I will try logging in to sunsolve with my a/c and see..
