A userApplication failover or degeneration occurred because of Oracle listener resource failure.
[Case 1] (Standby Operation, Scalable Operation with Oracle RAC, Single-Node Cluster Operation)

TNSName (net service name)
If your setup information is incorrect, set proper values again. See “Chapter 2 Environment setup”.
