After upgrading your database applications and routines,
you should perform several post-upgrade tasks to ensure that your
database applications and routines perform as expected and at their
optimum levels.
Procedure
Perform the following post-upgrade tasks that apply to
your database applications and routines:
- Perform benchmark tests on your database
applications and routines in your production environment and compare
with the baseline results that you saved before the upgrade.
- Tune your database applications. Review important guidelines
related to:
See related concepts for information about additional factors
that can affect application performance.
- Tune your routines. Review important guidelines related
to:
In addition, review guidelines on improving the performance
of database applications that also apply to routines, such as the
guidelines on optimization classes, locks, concurrency, and query
tuning.
- Remove dependencies on functionality that is deprecated
in DB2® Version 9.7 in your database
applications and routines before that functionality becomes discontinued.
Refer to Deprecated or discontinued functionality that affects DB2 server upgrades.
- Adopt new DB2 Version
9.7 functionality in database applications, where appropriate, to
improve performance or add new functionality. Check the Sample files
to understand how the new functionality works.
