IBM Data Server DB2 - Manual (Page 229)

Chapter 5. Deploying pre-configured databases 215
Flexibility: Upgrading an existing database might not be as straightforward
as it appears:
– Keeping data in an existing database is difficult, especially if table layout
has changed.
– Redirected restore might be required if the storage device on the target
system is different from those defined in the backup image.
Using scripts
Using scripts is the most flexible method and gives you total control with the
deployment process. The trade-off is that scripts have to be created either
manually or by a tool, data loading can take time, and additional tests are
required to ensure that no errors are introduced on the manually created
database.
5.1.1 Sample database
In this chapter we use a sample database named ITSODB for our examples.
This database consists of a subset of objects from the SAMPLE database that
comes with DB2.
We have taken, from the SAMPLE database, the minimum objects that are
sufficient to demonstrate our pre-configured database deployment examples.
We have the following database objects in ITSODB:
Table
Index
Summary table
Primary key
Foreign key
View
Stored procedure
Function
Trigger
Alias
Check constraint
Table space
