Apologies in advance for making assumptions. Curious as to how you're planning to run this on all your dbs?

Try these:
- select * from all_users where username in ('user1', 'user2', 'user3');

  • select count(1) from all_users where username in ('user1', 'user2', 'user3');
  • select vi.instance_name, au.username from v$instance vi, all_users au where au.username in ('user1', 'user2', 'user3');
