database performance - test setup

database performance: test setup: DB2

Note: The GUI Installer can fails with some X11 environments.
We simply accept all the defaults (and just provide some passwords).
Then, as user 'dbinst1' (the default user who owns this newly installed instance):

cd /opt/ibm/db2/V9.1
./bin/db2
> create database test
The database is started with:
/opt/ibm/db2/V9.1/instance/db2istrt

The database can then be access with the JDBC URL:
jdbc:db2://localhost:50000/test
The default connections will use isolation level 2: "Read Committed".
