Who is the System Administrator?
The distinction between programmer and system administrator varies considerably between mainframe sites. In small IT organizations, where one person may have multiple roles, terms can be used interchangeably.
In large IT organizations with multiple departments, job responsibilities tend to be more clearly separated. System administrators make several regular tasks related to keeping critical business data, while the system programmer attention on maintaining the system itself. One of the reasons for the segregation of duties is to follow auditing procedures, which often require that no one in IT can have free entree to sensitive data/information or resources.
Examples of SA (System administrator) include the database administrator (DBA) and the security administrator.
While the expertise of system programmers is primarily in the hardware and software areas of the mainframe, Freelance system administrators are more likely to have application experience. It often interfaces directly with application developers and end-users to ensure the administrative aspects of applications are met. These roles are not necessarily specific to the mainframe environment but are critical to their proper functioning.
In large IT organizations, the system administrator provides maintenance of the system software environment for business purposes, including the maintenance of daily systems to ensure their proper operation. For example, the DB administrator must ensure the integrity and efficient access to the data stored in the database management systems.

- Installation of the software
- Add and delete users and manage user profiles
- Maintenance of access lists to security resources
