A job role separation configuration of Oracle Database and Oracle ASM is a configuration with groups and users to provide separate groups for operating system authentication.

Review the following sections to understand more about a Job Role Separation deployment:

• About Oracle Installations with Job Role Separation
  Job role separation requires that you create different operating system groups for each set of system privileges that you grant through operating system authorization.
• Standard Oracle Database Groups for Database Administrators
  Oracle Database has two standard administration groups: OSDBA, which is required, and OSOPER, which is optional.
• Extended Oracle Database Groups for Job Role Separation
  Oracle Database 12c Release 1 (12.1) and later releases provide an extended set of database groups to grant task-specific system privileges for database administration.
• Creating an ASMSNMP User
  The ASMSNMP user is an Oracle ASM user with privileges to monitor Oracle ASM instances. You are prompted to provide a password for this user during installation.
• Oracle Automatic Storage Management Groups for Job Role Separation
  Oracle Grid Infrastructure operating system groups provide their members task-specific system privileges to access and to administer Oracle Automatic Storage Management.
