Drop all users in the database

edited Jun 17, 2017 5:00AM in Database Administration (MOSC) 4 commentsAnswered

Dear Experts,

We  planned, to migrate our productive database in a test involvement.

As an OS platforms are different we are going to use export/import utilities.

DB version for both environment are  RAC 12c.

But the problem is that, test database is very messy and we have to clean it up before migration.

To do this job I'm going to drop all users in the database but systems.

As a number of users are more than 2 hundred could you to tell me how to distinguish system users from ordinary ones? I'm afraid not to drop system users as well.

Howdy, Stranger!
