1. On Windows, open a command prompt and type db2cmd. This will open the CLP.
On Linux, log on to the DB2 server as the DB2 instance owner (normally
db2inst1), and open a terminal window.
2. Input this statement to create the DB2 database TESTDB as shown in Figure 4.2.
Creating the database takes a few minutes to complete.

Note:
Figure 4.2 - Creating the DB2 database TESTDB from the CLP
You now have a DB2 database ready for use.
DB2 provides a sample database called SAMPLE. This database is normally created by
default after DB2 installation; therefore, you could use this database for the exercises in
this book too.
4.2.2 Configuring and deploying a database pool
Community Edition provides a user interface to configure a database pool step by step. A
typical database pool configuration includes these steps:
1. Install the database vendor JDBC driver
2. Configure and deploy the database pool
4.2.2.1 Installing the database vendor JDBC driver
JDBC is a set of APIs for Java that define how a client accesses relational databases. Most
database vendors provide JDBC drivers for their databases. There are different drivers
supported in DB2 as shown in Table 4.1 below.
