Patching Solaris 10

Hello to all, I have a quick question. I am learning Solaris, with Solaris 10 x86, and one of the chapters in the manual is about patching. So can I download free patches from the Sun page, I mean with out paying a license. Because It would be a great exercise to patch my installation of Solaris. (I installed in a vmware). If it �s not possible, is there a way of download them from other site. The main purpose it �s to exercise my skills (the ones I am getting from the book I am reading =D)

Thanks in advance to all of you !

You have to download the recommended patches from Sunsolve
