The system programmer installs, customizes, andmaintains
the operating system, andalso installs or upgrades products that run
on the system.
The system programmer might be presented with the latest
version of the operating system to upgrade the existing systems.
Alternatively, the installation might be as simple as upgrading a
single program.
The system programmer must be skilled at debugging
problems with system software. These problems are often captured
in a copy of the computer's memory contents called a dump, which
the system produces in response to a failing software product, user
job, or transaction. Armed with a dump andspecialized debugging
tools, the system programmer can determine where the components
have failed. When the error has occurred in a software product, the
system programmer works directly with the software vendor's
support representatives to discover whether the problem's cause is
known andwhether a patch is available.
