A DB2 instance is a logical Database Manager environment for DB2. It is used to manage databases. You can create multiple instances according to your requirements.

An instance directory contains:

  • Database Manager Configuration file
  • System Database Directory
  • Node Directory
  • Node Configuration File [db2nodes.cfg]
  • Debugging files, dump files

The default instanceor for DB2 Database Server is "DB2". You cannot change the location of Instance directory after its creation. An instance can manage multiple databases. In an instance, each database has a unique name, its own set of catalog tables, configurations files, authorities and privileges.

Note: You can create multiple instances in one DB2Server on Linux, UNIX and Windows. You can also install multiple DB2Servers on a physical machine.

Create Instance on Linux

If DB2 Server is installed as root user then you can create multiple instances on Linux and UNIX. An instance can run simultaneously on Linux and UNIX independently. You can work within a single instance of the database manager at a time.

An Instance folder contains database configuration files and folders. The Instance directory is stored at different locations on Windows depending on the operating system versions.
