Explain the utilities which help the DBA to manage the database?

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.
