4.1.3  Instance creation

For our project we let DB2 UDB create the DB2 instance automatically during 

installation. 

While this is default, you can turn automatic instance creation off during 

installation as shown in Figure 4 3, and create instances and databases 

manually after the installation has completed. 

Figure 4 3   Instance creation option

DB2 UDB provides two methods to manually create instances:

The 

db2isetup

 command starts a graphical tool for creating and configuring 

instances as shown in Figure 4 4. It allows you to specify all the required 

configuration parameters such as the instance owner and communication 

protocol in an easy and guided fashion. The command can be found in 

/opt/IBM/db2/V8.1/instance.

The 

db2icrt

 command creates an instance, for example:

db2icrt u db2fenc1 db2inst1
