I am running following solaris OS on I386 processors:

$ uname -a SunOS oobleck 5.10 Generic_127128-11 i86pc i386 i86pc $ CC -V CC: Sun C++ 5.8 Patch 121018-11 2007/05/02

I checked on Oracle's web page and it seems that there latest version is Solaris 10 sun-dot-om/software/solaris/releases.jsp

The instruction set is:

$ isainfo -kv
64-bit amd64 kernel modules

However when I look at the fixpacks available , for solaris 10 it says Solaris OS 5.10

So I have 2 questions:

  1. Does Solaris 10 mean 5.10?
  2. What is the latest version of OS and fix pack I should upgrade the machine to ?

Solaris 10 includes SunOS 5.10. uname -a will show the SunOS version as you saw. cat /etc/release will show the Solaris version.

Currently the latest version of Solaris 10 is Solaris 10 10/09. Patches for it are available from and require a support contract to download now. (The pages you linked to are only the subset of fixes needed for the compilers/developer tools, not the whole OS.)

Thnx for the reply.. the latest version for 5.10 it shows was released on Jan 2005 ! No other major release after that . Also, which latest fix pack etc I shld get for my system ? – unx Jul 20 '10 at 15:11
There have been updates on that of course. I think the last was 10/09 – topdog Jul 20 '10 at 15:23
The page is not being kept up to date -… is more current. – alanc Jul 20 '10 at 17:01

This is question is a little bit old, but it showed up on the front page today so I'll update and add some missing info.

At current (2012-08) the most recent release of Solaris 10 from Oracle is Solaris 10 8/11. Solaris 10 downloads are here.

You should be running the most recent release, plus any patches available (unless otherwise instructed by Oracle support). To find patches available run:

smpatch analyze

To install them run:

smpatch update

There will be more patches available to you if you have a valid support contract.
