One of my colleague reported he is facing issue while trying to connect instance from back-end using sql-developer.
Issue :
Status : Failure - Test failed : IO Error : Got minus one from a read call
Solution :
After changing a parameter "tcp.validnode_checking" in sqlnet.ora file, this issue is resolved and can connect from back-end successfully.
Before change
After change
