Now, I have the infrastructure up and running. It consists of a VM in Azure, an Autonomous Database (ATP) Oracle Cloud Infrastructure (OCI), and a Java application on the VM. The application successfully connected to the database.
However, after some period of time application fails with:
ORA-03113: end-of-file on communication channel
Process ID: 86437
Session ID: 57114 Serial number: 29955
How can I identify where is the problem (Azure, OCI, etc.) in order to have an idea of how to fix it?
