Upgrading clients in a test environment before you upgrade
them in your production environment allows you to address problems
during the upgrade process more effectively and to evaluate the impact
of changes introduced in DB2® Version 10.1.
Before you begin
- You must have root user authority on Linux and UNIX operating
systems or Local Administrator authority on Windows. You must also have SYSADM authority.
Restrictions
- On Linux and UNIX operating systems, you must
not set up the instance environment for the root
user. Running the db2iupgrade or the db2icrt command
when you set up the instance environment is not supported.
Procedure
To duplicate your production environment in a test environment,
perform the following tasks:
- Install the same client and version that you have in your
production environment in a test system.
- Re-create your client instance by running the db2icrt command
with the -s option:
| Operating system |
DB2 command |
|---|
| Windows |
"%DB2PATH%"\bin\db2icrt -s client InstName |
| Linux and UNIX |
$DB2DIR/instance/db2icrt -s client InstName |
where DB2PATH and DB2DIR are
set to the location of the client copy that you installed in the previous
step, and InstName is the name of the instance.
- Perform the pre-upgrade
tasks that apply to your client.
- Install a DB2 Version 10.1 client that you can upgrade to depending on the client
that you are upgrading from. Select the Install New option
to install a new copy. Refer to Table 1 to determine what
client product to install.
- Upgrade your client instance by running the db2iupgrade command:
| Operating system |
DB2 command |
|---|
| Windows |
"%DB2PATH%"\bin\db2iupgrade InstName |
| Linux and UNIX |
$DB2DIR/instance/db2iupgrade InstName |
where DB2PATH and DB2DIR are
set to the location of the DB2 Version 10.1 client copy that you installed in the previous step,
and InstName is the name of the instance.
- If you found any issues upgrading your test client instance,
resolve these issues and add the tasks to resolve these issues to
your upgrade plan.
- Perform post-upgrade
tasks that apply to your client.
- Verify
that the client upgrade was successful.
- Test your applications, scripts, tools, and maintenance
procedures by using the DB2 Version 10.1 client.
