  Oracle Database Tips by Donald Burleson

Creating Roles

To implement a role, you first create the role and then grant system and object privileges to that role. When you create the role, there are three password options available: 

  • No authentication

  • Operating system authentication

  • Password authentication      

You can set operating system authentication when the role is created or by using the database initialization parameters OS_ROLES=TRUE and REMOTE_OS_ROLES=TRUE. Note, however, if you are using the multithreaded server (MTS) option, you cannot use operating system authentication for roles.      

In order to create a role, you must have the CREATE ROLE system privilege. You can create roles with Server Manager or at the command line in SQL*Plus. The command-line syntax for creating a role is:

See Code Depot  

For example:

See Code Depot    

To alter a role, you must have the ALTER ANY ROLE system privilege or have been granted the role with the WITH ADMIN OPTION. The creator of any role automatically has the WITH ADMIN OPTION for that role. Note that this command only creates the role that acts as a tag for later storage of a grants list; it has no implicit grants. The privileges and grants to a role are made identically to the method used to grant to users. Roles may also be granted to other roles in the form of a role hierarchy.
