Hi Mahesh,
You can see in the alfresco.log that the application is not starting up because of a misconfiguration. It is attempting to look for a host called "myserver" but that's not resolving to any ip address that it can find. So either you still have some placeholder values in your alfresco-global.properties file (usually in tomcat/shared/classes/ by default) or else the server your running on is calling itself myserver, but you don't have a local hosts reference that maps that name to the localhost ip (e.g. 127.0.0.1)
Regards
Steven
