If i'm getting a "PHP Fatal error" the first thing i would do is to search some online resources like a search engine or the PHP manual to find a solution. I think it could be also possible that you just have not fulfilled all requirements for ownCloud, then the manual of ownCloud about the prerequisites might help as well.

same configuration is working on my other machine .with same codes .i am working with drbd wiht owncloud

I think another machine can have another installed packages or a complete different base install. If both machines would share the same base then i think you wouldn't see this message.
