As stated before, no platform specified, and using some ideas from earlier answers:

I am considering a containerised application. You could store the password for the database in a file in the container.

With a successful db connection the file with the credentials is deleted and the variables containing the these, are removed. So when you start serving requests, the only thing that remains, is an open database handle to use from this moment on. If for any reason the database connection is lost, you simply quit and wait to restart the container, the credentials file will be there again.
