I get this question asked several times. What kind of jobs does IBM mainframes offer?
For starters, mainframe computers are large, multi-processor computing devices able to perform thousands of tasks every second. Mainframes that are now the size of your refrigerator run the most critical work of our top industries today. This includes large financial institutions like banks, insurance companies, health care, utilities, government, military, and a multitude of other public and private enterprises. Mainframes are a multi-billion dollar industry.
Given Mainframes wide spread use and their significant market dominant position, it naturally provides wide variety of roles that are needed to support and operate the system. Lets look at each role in detail.
- System programmers
The system programmer duties include installing, customizing, and maintaining the operating system, and other application products.
- System administrators
System administrators duties include more of the day-to-day tasks related to maintaining the critical business data that resides on the mainframe. Example DBA DataBase Admin.
- Application programmers
The Application programmers or developer duties include designing, building, testing, and delivering mainframe applications.
- System operators
The System operator monitors and controls the operation of the mainframe hardware and software. Basically actively monitoring the system logs or message for any problems.
In smaller IT organizations, sometimes one person may perform several roles, so the terms may be used interchangeably.
There you have it! Its now your turn, what you wanted to be? I am Application programmer and designed, built several top notch mainframe applications that are brings millions of dollars as revenue to my company.
