On the Windows operating systems, there are two
ways to upgrade your Db2 32-bit server to a
Db2
version 11.1 64-bit server.
One way is to upgrade your existing
32-bit server to
version 11.1 32-bit server, and then upgrade to
version 11.164-bit server.
The other way is to upgrade to a new computer where Db2 version 11.1 64-bit database product is installed.
Before you begin
Restrictions
- This procedure is covered by this task and only applies to Windows on x64.
- Additional upgrade
restrictions apply. Review
the complete list.
Procedure
To upgrade a pre-Db2 version 11.1 32-bit server to a Db2 version 11.1 64-bit server:
-
Log on to the Db2 server as a user with
Local Administrator authority.
-
If you have multiples copies of Db2 Version 10.1, or
Db2 Version 9.7
or 32-bit server, perform the following actions to have all instances running under one Db2 copy:
- Update all your instances to
run under one Db2 Version 10.1 or Db2 Version 9.7 32-bit
server copy. You can only update instances of the same version.
- If you have instances running on multiple pre-Db2
version 11.1 copies of different version, upgrade all instances to the highest release of pre-
version 11.1 copies. For example, if you have a Version 10.1 and a Version 9.7 instance,
upgrade your Version 9.7 instance to the Db2 Version 10.1 32-bit
server copy.
- Uninstall all the remaining Db2 server copies except
the Db2 server
copy where all instances are running. You should have only one Db2 Version 10.1 32-bit
server copy, or Db2 Version 9.7 32-bit
server copy
-
Install Db2
version 11.1 64-bit database product and select the Work with
Existing option on the Install a Product panel. Then in the Work with an existing window, choose the Db2 copy name with the
upgrade action.
-
If you want your applications to access Db2
version 11.1 copy through the default interface, set the
Db2
version 11.1 copy as the Db2 default copy
.
- Upgrade your databases.
-
If you want to have your instances running on multiples copies of Db2
version 11.1, install additional
version 11.1 copies and issue the db2iupdt command to run an instance
under a different
version 11.1 copy.
What to do next
After upgrading the Db2 server, perform the
recommended post-upgrade tasks such as resetting the diagnostic
error level, adjusting log space size, and rebinding packages. In addition, verify that the upgrade of your Db2 server was
successful.
