what is the difference in running oracle database on solaris and linux operating system

Hi,

That's not an easy question, what do you mean by differences ? Cost ? Performance ? The application is the same, the main differences are at the operating system level...

Yes , would like to know is there any improvement in performance, memeoy management, IO handling etc

I don't know of any major difference between Oracle Solaris ou Oracle Linux, besides those that are operating system and hardware specifics ( Oracle doesn't support Solaris x86, so besides the OS, there's a huge difference in hardware too )... Personally, I choose Solaris or HP/UX for a Oracle DB...

Check this document http://www.interealm.com/technotes/roby/pentmark.html , it "talks" about Oracle on linux and Oracle on windows ( same hardware ), below there's a table where Oracle for Solaris and HP/UX are mentioned as well...

In the meantime, if somebody has a different answer...
