Explain the utilities which help the DBA to manage the database?
Every DBA uses database utilities to maintain and control their databases. But there is a lot of confusion within the field as to what, exactly, is a database utility. There are a many of definitions floating around out there. DBAs constantly refer to utilities, tools, solutions, and suites.
So, first of all, let's be clear on what a utility is and what is a "tool" or "solution." A utility is generally a single reason program for moving and/or verifying database pages; examples involves LOAD, CHECK, REORG, UNLOAD, COPY, and RECOVER. A database tool is a multi-functioned program designed to simplify database monitoring, management, and/or administrative tasks. A solution is a synergistic group of tools and utilities designed to work together to address a customer's business issue. A suite is a group of tools which are sold together, but are not necessarily integrated to work along with each other in any way. Of course, these are only my definitions. But there are meaningful definitions which creates it easier to discuss DBA products and programs
