Note: ogg2 is an Oracle 19c built on a 4GB-memory machine. This is less than the minimum acceptable memory for Oracle 19c. If you face memory issues on it, you need to increase its dedicated memory to 6GB.
Note: ogg1 is an Oracle 12c built on a 4GB-memory machine. It is recommended to increase the VM memory to 6 GB.
