What Are The SQL Server Agent Roles

SQL Server 2005 and later versions introduces the following msdb fixed database roles, which give administrators finer control over access to SQL Server Agent. With this roles we can give access to developers only view their owned jobs.

1. SQLAgentUserRole
2. SQLAgentReaderRole
3. SQLAgentOperatorRole

SQLAgentUserRole Permissions:

SQLAgentUserRole is the least privileged of the SQL Server Agent fixed database roles. It has permissions on only operators, local jobs, and job schedules. Members of SQLAgentUserRole have permissions on only local jobs and job schedules that they own. They cannot use multiserver jobs (master and target server jobs), and they cannot change job ownership to gain access to jobs that they do not already own. SQLAgentUserRoleJob Step Properties dialog box of SQL Server Management Studio. Only the Jobs node in SQL Server Management Studio Object Explorer is visible to members of SQLAgentUserRole.

SQLAgentReaderRole Permissions:
SQLAgentReaderRole includes all the SQLAgentUserRole permissions as well as permissions to view the list of available multiserver jobs, their properties, and their history. Members of this role can also view the list of all available jobs and job schedules and their properties, not just those jobs and job schedules that they own. SQLAgentReaderRole members cannot change job ownership to gain access to jobs that they do not already own. Only the Jobs node in SQL Server Management Studio Object Explorer is visible to members of the SQLAgentReaderRole.

SQLAgentOperatorRole Permissions:
 SQLAgentOperatorRole is the most privileged of the SQL Server Agent fixed database roles. It includes all the permissions of SQLAgentUserRole and SQLAgentReaderRole. Members of this role can also view properties for operators and proxies, and enumerate available proxies and alerts on the server.

 SQLAgentOperatorRole members have additional permissions on local jobs and schedules. They can execute, stop, or start all local jobs, and they can delete the job history for any local job on the server. They can also enable or disable all local jobs and schedules on the server. To enable or disable local jobs or schedules, members of this role must use the stored procedures sp_update_job and sp_update_schedule.
