Issue with database connection
We have our dev system application server and database on two different AWS EC2 instances. But recently we have migrated our database from EC2 to RDS and from then we are unable to connect to application.
There is an error as below.
IO Error: The Network Adapter could not establish the connection.
Make sure you have things set up correctly for Oracle. The message is basically telling you that Oracle has no idea what you are trying to connect to.
Can you log into the database on the Agile application server using SQL Plus or SQL Developer?? If not, then you need to use the Network Manager (on the application server) to correctly define the connection string for the database in it’s new location.
