Error Description
status failure - test failed io error got minus one from a read call, while connecting to Oracle EBS Database from SQL Developer
Root Cause of the Issue
SQL Net is not allowing connections to the database because of the setting 'tcp.validate_node' is set as 'yes'.
Resolution
1. Open sqlnet.ora
2. Change the setting to:
tcp.validate_node = no
3. Now try reconnecting to the database from SQL Developer and you should be able to connect it successfully this time.
