Before you install DB2® database products on AIX® operating systems, ensure that
the system you choose meets the necessary operating system, hardware,
software, and communications requirements.
DB2 database products
are available in several different editions. Some DB2 database products and features are only available
on specific operating systems.
If you are planning to install the IBM DB2 pureScale® Feature,
different installation prerequisites are required. See the Installing
the DB2 pureScale Feature
topic.
To install a DB2 database
product, the following requirements must be met:
Table 1. AIX installation requirements| Operating System |
Hardware |
|---|
AIX Version 6.1 2- 64-bit AIX kernel is required
- AIX 6.1 Technology Level (TL) 6
and Service Pack (SP) 5
- Minimum
C++ runtime level requires the xlC.rte 11.1.0.1 and xlC AIX rte 11.1.0.1 (or later) filesets.
AIX Version 7.1 - 64-bit AIX kernel is required
- AIX 7.1 Technology Level (TL) 0
and Service Pack (SP) 3
- Minimum
C++ runtime level requires the xlC.rte 11.1.0.1 and xlC AIX rte 11.1.0.1 (or later) filesets.

64-bit Common Hardware Reference
Platform (CHRP) architecture, excluding POWER3 processor-based systems. 1
All
processors that are capable of running the supported AIX operating systems.
|
- 1 To verify that it is a CHRP architecture
system, issue the command lscfg and look for the
following output: Model Architecture: chrp.
For POWER3 processor-based
systems, first upgrade to POWER4 processor-based systems. POWER3 processor-based
systems are not supported.
- 2 In AIX 6.1
there are two types of Workload Partitions (WPARs): system WPARs and
application WPARs. DB2 installation
is supported only on a system WPAR. AIX 6.1
also supports the ability to encrypt a JFS2 file system or set of
files.
- 3 Additional considerations for POWER7® systems:
- DB2 products
running on POWER7 systems
support Active Memory™ Expansion.
- 32-bit
clients are also supported
Note: If
the minimum operating system requirements were applied using an operating
system upgrade rather than using a new operating system installation,
you must install I/O completion ports (IOCP) separately.
You
can obtain the IOCP libraries from the AIX installation
CD and configure IOCP on the DB2 server.
For a client only installation, IOCP is not required. For more
information, see
configuring IOCP on AIX.
Software considerations
- For application development and runtime considerations, see the
topics in Supported programming languages and compilers for database
application development.
- You can download the latest IBM C++
Runtime Environment Components for AIX at
the IBM AIX XL C and C++ support website.
- (Clients only) If you plan to use Kerberos Authentication, you
require IBM Network Authentication
Service client v1.4 or later.
- Use the bosboot command to switch to the 64-bit
kernel.
To switch to a 64-bit kernel, you require root authority
and enter the following commands:
ln -sf /usr/lib/boot/unix_64 /unix
ln -sf /usr/lib/boot/unix_64 /usr/lib/boot/unix
bosboot -a
shutdown -Fr
One of the following browsers
is required to view online help and to run First Steps (
db2fs):
- Firefox 3.0 and later
- Google Chrome
- Safari 4.0
- An X Window System software capable of rendering a graphical user
interface is required if you want to use the DB2 Setup wizard
to install a DB2 database product
on Linux or UNIX operating systems.
- Live Partition Mobility (LPM) is supported in partitioned
database environments with multi physical node configurations.

see www.ibm.com/support/docview.wss?uid=swg21165448
Mounting considerations
For root installations
of DB2 products on UNIX operating systems, do not mount your file
system with the nosetuid option.
