B.7 Connecting to a database<br />
If your database is local, that is, it resides on the same system where you are performing<br />
your database operation; the connection setup is performed automatically when the<br />
database is created. You can simply issue a connect to database_name statement to<br />
connect to the database.<br />
If your database is remote, the simplest method to set up database connectivity is by using<br />
the Configuration Assistant GUI tool following these steps:<br />
1. Start the Configuration Assistant from the system where you want to connect to the<br />
database. To start this tool, use the command db2ca from a Windows command<br />
prompt or Linux shell. Figure B.9 shows the Configuration Assistant.
