I configured source and target endpoint for DMS services, The migration I need to perform is from EC2 to Oracle RDS using AWS DMS and both are 12c.
I am testing the source end point and I am getting this error
Endpoint identifier Replication instance Status Failure message ec2-172-31-6-111 test-dms-oracle failed Error Details: [errType=ERROR_RESPONSE, status=1022307, errMessage=ORA-12514: TNS:listener does not currently know of service requested in connect descriptor OCI error., errDetails=]
I don't feel this occurs because of Network error since, I tried testing the connection with all ports open. And I can able to access the DB within EC2 please refer the screenshot
Please help me to find the solution.
