Chapter 2. Getting Started > The DB2 Environment

The DB2 Environment

Before creating and working with databases, you need to understand the DB2 environment. The DB2 environment controls many database-related factors, such as what protocols may be used for accessing remote databases, what paths should be used by applications when searching for database-related files, how much memory will be allocated for various buffers that databases and applications use, and how the system will behave in certain situations. This complex environment is controlled by several different mechanisms including:

  • DB2 Profile Registry

  • Environment variables

  • Configuration parameters
