dear sunil,
check ur tns.ora...whether u are connecting to the right oracle srvr.
this(12560) is general protocol adapter error.
and...may be the listener is not working on srvr side.

2nd err. msg.(ora 1012)..is related to the same prob.
here is the ora documentation for this err. code.
ORA-01012 not logged on

Cause: A host language program issued an Oracle call, other than OLON or OLOGON, without being logged on to Oracle. This can occur when a user process attempts to access the database after the instance it is connected to terminates, forcing the process to disconnect.

Action: Log on to Oracle, by calling OLON or OLOGON, before issuing any Oracle calls. When the instance has been restarted, retry the action.

chalo...

cheers!
Rahul
