Server IP for data source is wrong.
In oracle, usually the database resides on a server and it uses a service name (tnsname) to connect to the DB server. the service name or the tnsname should be there on both i.e server and the client machine as well. Use NetConfiguration Assistant to create a tnsname.
let me know if you need more help on this.
