Getting Started with DB2 Express-C

Chapter 4 – DB2 Environment 67
Figure 4.9 – Buffer pool and logs created by default
Earlier we discussed that instances are independent environments, and therefore, a
database with the same name could be created in several instances. Just like instances,
databases are also independent units; therefore, objects in one database have no
relationship to objects in another database. Figure 4.10 shows a table space mytbls1
inside both the MYDB1 database and the SAMPLE database, within instance DB2. This is
valid because the databases are independent units. Note that Figure 4.10 does not show
the other default objects of database SAMPLE due to space constraints in the figure.
