you are completely doing the wrong thing.

Either have 3 sites on 3 servers using 3 different databases, or you have one cluster of 3 nodes using 1 database and a vhost configuration.

But never ever do non-clustered instances use the same database.

This will never work.

When you add, say, a user to the DB, the user also gets stored in the local cache.

When you have 3 non-clustered instances, the other two nodes do not get updated w/ the new user and therefore it is not available. You are left constantly rebuilding the search indices on all of the nodes to capture all of the new records that has been created.

It just won't work and Liferay wasn't designed to handle it. Your employer could mandate that your systems must run on old 286 hardware powered by hamsters running in little wheels, but that doesn't mean you will ever be able to deliver it.
