The problem is your TNS. Check these three solutions :
Make sure that "TNSNAMES" is listed as one of the values of the NAMES.DIRECTORY_PATH parameter in the Oracle Net profile (SQLNET.ORA)
Verify that a TNSNAMES.ORA file exists and is in the proper directory and is accessible.
Check that the net service name used as the connect identifier exists in the TNSNAMES.ORA file.
