I am using ORDS 22.2.0 | APEX 22.1.0 with XE21c. All works wonderful.
But if I start ORDS before the DB, the following error occurs and ORDS never (waited several hours) connects to the database again:
WARNING The pool named: |default|lo| is invalid and will be ignored: ORDS was unable to make a connection to the database. This can occur if the database is unavailable, the maximum number of sessions has been reached or the pool is not correctly configured. The connection pool named: |default|lo| had the following error(s): IO Error: The Network Adapter could not establish the connection (CONNECTION_ID=xxK1jRAIRRqeVnG06ZuFYQ==)
If I start the DB before ORDS, everything is fine. The connection is restored after restarting the DB.
