WHAT EXACTLY IS A DBA? - A system DBA
System DBA
A system DBA focuses on technical rather than business issues, primarily in the system administration area. Typical tasks center on the physical installation and performance of the DBMS software and can include the following:
*
Installing new DBMS versions and applying maintenance fixes supplied by the DBMS vendor
*
Setting and tuning system parameters
*
Tuning the operating system, network, and transaction processors to work with the DBMS
*
Ensuring appropriate storage for the DBMS
*
Enabling the DBMS to work with storage devices and storage management software
*
Interfacing with any other technologies required by database applications
*
Installing third-party DBA tools
System DBAs are rarely involved with actual implementation of databases and applications. They might get involved in application tuning when operating system parameters or complex DBMS parameters need to be altered.
Indeed, the job of system DBA usually exists only if the organization does not have an official system administration or systems programming department.
