Before
you install a DB2® database product
on Windows operating systems,
ensure that the system you choose meets the necessary minimum operating
system, hardware, and software requirements.
In addition to system requirements, installing a DB2 product on supported Windows operating systems has
these additional considerations.
- Windows Installer 3.0
is required. It will be installed by the installer if is it not detected.
- IBM Data Server Provider
for .NET client applications and CLR server-side procedures require
.NET 2.0 or later framework runtime. In an x64 environment, 32-bit IBM data server provider for .NET
applications will run in the WOW64 emulation mode.
- If you plan to use LDAP (Lightweight Directory Access Protocol),
you should use either a Microsoft LDAP
client or the IBM Tivoli® Directory Server v6 client (also known
as the IBM LDAP client which
is included with DB2 database
products). Before installation of the Microsoft Active Directory, you will need
to extend your directory schema using the db2schex utility,
which can be found on the installation media under the db2\Windows\utilities
directory.
The Microsoft LDAP
client is included with Windows operating
systems.
- One of the following browsers is required to view online help,
run the DB2 install launchpad
(setup.exe), and to run First Steps (db2fs):
- Firefox 2.0 and later
- Internet Explorer 6.0 and later
- Mozilla-based browsers 1.7 and later
- Safari 3.0 and later
- The
computer name of the Windows workstation
on which the DB2 installation
files are located, must be 15 characters or less in length.
- DB2 must be installed on a drive with short names enabled or a
directory with no spaces such as E:\DB2\SQLLIB. To check the current 8.3 file
name settings for a drive, in a command window with administrator privileges,
enter
fsutil.exe behavior query disable8dot3
The following possible values are
returned when you run the command: - 0: Create 8.3 short file names (default)
- 1: Do not create 8.3 file names
- 2: Set 8.3 file names on a per volume basis
- 3: Disable 8.3 file names on all volumes, except the system volume
The registry state of
NtfsDisable8dot3NameCreation is 0, which means
that 8.3 file names are enabled on all volumes. To enable 8.3 file names on a global basis, enter
fsutil.exe behavior set disable8dot3 0
If DB2 is installed on a drive without 8.3 name support andin a directory without
spaces, it must be reinstalled on a drive with 8.3 name support. If the folder you are trying to
install DB2 is already created when 8.3 name support is
disabled, then the short name is not created if you try a reinstall onto the same directory. Windows
short names are created during the directory creation, hence you must install it into a new
directory or if the directory is empty delete the directory and allow recreation.
Note: DB2 database products
support the hardware-enforced Data Execution Prevention (DEP) feature
that is built into some Windows operating
systems.
