SQLException: Io exception: The Network Adapter could not establish the connection'

Hi Friends,

My Scenario is JDBC to Proxy,

this is now in quality phase  now. end user keep some test data in their table.

while testing in RWB i am getting following error.

Error: “Error during database connection to the database URL 'jdbc:oracle:thin:@10.202.208.15:1521:NCP' using the JDBC driver 'oracle.jdbc.driver.OracleDriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Can not establish connection:: SQLException: Io exception: The Network Adapter could not establish the connection'”

i  cross checked with oracle db team regarding my db connection details like ip address, port and dbname. all are ok.

please tell me where exactly this error occurs?

Regards,

Ravi
