            Issue got fixed. Primary database was able to connect to secondary hosts but in return secondary host can't. So I adjusted the security groups and connected. Takeaway is all the primary and secondary hosts should be able to connect with each other in mongodb port (27017)

            I think you are looking for a thread-safe implementation of a Singleton class here. Of course, the way to achieve this is using enums, but for your case, you can implement double-check locking to ensure no two threads can call new MyPool() simultaneously.

            Also, I think in your code, you are actually implementing a factory class, not really a singleton. Your MyPool is a different class than Singleton, which could have a public constructor.

            I have made the appropriate changes with comments.

            Double check-locking basically just checks the thread-safety before and after null-check, because the whole method is not synchronized, so two threads can indeed get the null value in the condition even after synchronization block, hence the second synchronization.

            Also, I think your getPool() should be static. You won't be able to call getPool() without an explicit object of Singleton, which I think you don't need.

            The secondary node was unable to become primary because the arbiter voted no, which might have been related to it being unable to resolve the DNS name:

            The arbiter voted no because it wasn't yet aware that the primary was shutting down:

            Suggestions:

            • Run the replSetStepDown command and wait for a new primary to be elected before shutting down the primary's container.
            • Check the primary logs to see if it tried to step down prior to shutting down.
            • Don't use arbiters unless absolutely required

            I think you are consuming the OResultSet outside the Try block, this means that the session is closed and the rs can't fetch more data from the database anymore.

            Make sure the Firewall rules are enabling this. To do

            • configure the firewall rule in Google cloud console
            • provide a tag in your firewall rule
            • tag your instance with the same tag as the firewall rule

            Express Passport.js not persisting user object in session
            Asked 2019-Dec-28 at 23:26

            I have an Express application running on port 3000. The front end runs on port 80, so this is a CORS application. Users are stored in an SQL server database. I'm using passport as the authentication method with Local Strategy as well as express session middleware. The application is a Single page application and all requests sent to server are done via ajax. Users log in on page and the credentials are sent and if authentication is successful, userID as well as username and FullNmae are supposed to be persisted to a session.

            I have a lot of things wrong with this: The main thing is that after logging in, express saves the username and other data using passport on to a new session andsends back an html snippet to replace the body tag on the page. However, to test that the user object persists, I call the /create-user route and it says that the user object is not there. Additionally, a new session starts with every request (I check the logs and see that a different session ID is displayed each time). Not only that but at one point I was able to see the session cookie in the browser but I can no longer see it anymore. I tried to go back to the point where I could see the cookie but it still didn't appear!

            I've been busting my head for hours and can't figure out why deserializeUser is not called nor why the data is not persisted. Where am I going wrong?

            Note: some obvious code ommitted (app.listen(), require statements, etc.)
