Hello Jomsocial
For upgrade i have setup my application on my localhost,but the jomsocial is not working on my local machine.

Hi.

Make sure that your localhost settings meet our system requirements: documentation.jomsocial.com/wiki/System_Requirements

Also, please read our Support License: www.jomsocial.com/support

What we won't support:

Layout overhauls and making your site pixel-perfect - If the component works fine but you're not satisfied with the overall look and feel, you’ll need to hire a professional designer to customize the layout.
Changing the current functionality - JomSocial is delivered as is. All of its functions have been tested to work in common Joomla environments.
Changing the current functionality to achieve different behavior is not something we recommend. We don’t support it.
Adding new functionality - No matter how trivial, adding anything to the current base always requires time.
Moving HTML elements - Moving HTML elements in the layout is really not as easy as it sounds. What you’d think would be a ten-minute fix is more likely to be a ten-hour all-nighter. We’d really rather not.
You have purchased a standard licence and have removed or modified the backlink.
You have installed Jomsocial on a localhost or a non commercial hosting service
Domains that are not listed in your supported domains.
Everything else that is not specifically mentioned in the "what can we support" list.
