Explanation/Reference:
Enterprise Manager contains three built-in roles for the Database Cloud Service Portal, namely:
M_CLOUD_ADMINISTRATOR: Users with this role can set up and manage the cloud infrastructure. This
role is responsible for deploying the cloud infrastructure (servers, zones, storage, and networks) and
infrastructure cloud operations for performance and configuration management.
EM_SSA_ADMINISTRATOR: Users with this role can define quotas and constraints for the self service
users and grant them access privileges. Users with this role also have provisioning and patching designer
privileges that allow them to create and save deployment procedures, create and view patch plans, and
support the plug-in lifecycle on the Management Agent.
EM_SSA_USER: Users with this role, by default, can only access the Self Service Portal. An administrator
with the EM_SSA_ADMINISTRATOR role can provide additional privileges that allow users with the
EM_SSA_USER role to access other features in Enterprise Manager.
Note:
M_CLOUD_ADMINISTRATOR
Enterprise Manager user for setting up and managing the infrastructure cloud. This role could be
responsible for deploying the cloud infrastructure (servers, pools, zones) and infrastructure cloud
operations for performance and configuration management.
