Specifying mutual exclusivity

The mutual exclusivity feature lets you ensure that a login with a given role either cannot be assigned to another role or cannot use another role at the same time. Defining roles as mutually exclusive lets you enforce a policy of separation of duties. Mutual exclusivity is often used to prevent collaboration between job-related capabilities. For example, your business model might specify that separate transactions should be required to initiate a payment and to authorize a payment, and that no single individual should be capable of executing both transactions.

The system security officer can define mutual exclusivity at the membership level or at the activation level. When two roles are defined as being mutually exclusive at the membership level, the system security officer cannot grant the same login to both roles. When two roles are defined as being mutually exclusive at the activation level, the system security officer can grant a user both roles, but the user cannot activate both roles at the same time.
