Restricting access to ALL_USERS

in Database Administration (MOSC) 10 commentsAnswered ✓

Hi all,

I have an Oracle Database 19c, and would be interested to find out if anyone knows of any good solutions to how I can restrict users' access to ALL_USERS.

Currently, if a number of schemas containing data, and user access to those is provided by granting the user the Role for that schema. If the user does not have the Role for that schema, then I would prefer that they cannot determine that the schema exists. Currently, if they were to query ALL_USERS, they would be able to see all the schemas, even if they cannot access them.

Howdy, Stranger!
