Error database connection in JDBC Adapter

Hi Experts,

I am facing errror database connection problem in production system.

My interface was working fine in production till yesterday but suddenly from today i am facing the error connection problem.

Below is the error message i am getting.

Error during database connection to the database URL 'jdbc:oracle:thin:@<ip>:<port>:"' using the JDBC driver 'oracle.jdbc.driver.OracleDriver': 'com.sap.aii.adapter.jdbc.sql.DriverManagerException: Cannot establish connection to URL 'jdbc:oracle:thin:@'jdbc:oracle:thin:@<ip>:<port>:": SQLException: Io exception: The Network Adapter could not establish the connection'

Please advice what would be the problem.

I have checked the IP by pinging, its working fine.

Thanks,

Swetha Reddy
