We have an JAVA application on a server that connects remotely to an Oracle database server using JNDI. One connection has suddenly stopped working and when I run SQL Developer to test the database connections, the connections to the Test and Train databases work fine but the connection to the Live Oracle database shows the following status when I try to test the connection in SQL Developer;
"Test failed: IO Error: Connection reset"
How do I resolve this please? What has changed to make the connection fail?
Thanbks in advance
