Installation requirements for DB2 servers and IBM data server clients (AIX)

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.

To install a DB2 database product, the following requirements must be met:

Table 7. AIX installation requirements
Operating System	Hardware
AIX Version 5.3 64-bit AIX kernel is required AIX 5.3 Technology Level (TL) 9and Service Pack (SP™) 2 Minimum C++ runtime level requires the xlC.rte 9.0.0.8 and xlC.aix50.rte 9.0.0.8 (or later) filesets. These filesets are included in the June 2008 IBM® C++ Runtime Environment Components for AIX package. AIX Version 6.1² 64-bit AIX kernel is required Minimum C++ runtime level requires the xlC.rte 9.0.0.8 and xlC.aix61.rte 9.0.0.8 (or later) filesets. These filesets are included in the June 2008 IBM C++ Runtime Environment Components for AIX package.	64-bit Common Hardware Reference Platform (CHRP) architecture¹ All processors that are capable of running the supported AIX operating systems.

¹To verify that it is a CHRP architecture system, issue the command lscfg and look for the following output: Model Architecture: chrp
²In 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.

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 Web site.
(Clients only) If you plan to use Kerberos Authentication, you require IBM Network Authentication Service client v1.4 or later. The NAS client can be downloaded from https://www6.software.ibm.com/dl/dm/dm-nas-p.
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 2.0 and later
- Mozilla-based browsers 1.7 and later
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 product on Linux or UNIX® operating systems
