DB2 Version 9.7 for Linux, UNIX, and Windows

Installation requirements for DB2 servers and IBM data server clients (HP-UX)

Important: For the most up-to-date installation requirements for DB2® database products, you must start using the System requirements for IBM® DB2 for Linux, UNIX, and Windows and System requirements for IBM DB2 Connect™ technotes. These technotes use IBM Software Product Compatibility Reports (SPCR). With the SPCR tool, you can locate and find complete lists of supported operating systems, system requirements, prerequisites, and optional supported software for DB2 database products. This DB2 Information Centre topic might be removed in a future release or fix pack.

DB2 database products are available in several different editions. Some DB2 database products and features are only available on specific operating systems. See DB2 database product and packaging information for a list of DB2 database products that are available on each operating system.

To install a DB2 product on an HP-UX operating system, the following minimum operating system, hardware, and communications requirements must be met:

Note: Support for 32-bit HP-UX applications has been deprecated.

Table 1. HP-UX installation requirements
Operating System	Hardware
DB2 products are supported on: HP-UX 11iv2 (11.23.0505) with: May 2005 Base Quality (QPKBASE) bundle May 2005 Applications Quality (QPKAPPS) bundle PHCO_38637 - libc cumulative patch HP-UX 11iv3 (11.31) with: PHCO_38658 - libc cumulative patch To support SDK6, the following patches are also required: HP-UX 11iv2: PHSS_37201 HP-UX 11iv3: PHSS_37202	Itanium based HP Integrity Series Systems Any hardware that is explicitly compatible and fully capable of running the specified operating system, all the corresponding supporting software, and any associated applications unmodified.

Kernel configuration considerations

A system restart is required if you update the kernel configuration parameters. The kernel configuration parameters are set in /etc/system. Depending on the values of your kernel configuration parameters, modify some of them before you install the Version 9 client or DB2 server products. If the kernel parameter being modified is not listed as dynamic, a system reboot is required to make the changes to /etc/system take effect.

Software considerations

libpam.so.0 (32-bit) is required for DB2 database servers to run 32-bit non-SQL routines.
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.

Note: Starting in DB2 V9.7 Fix Pack 1 and later, DB2 products installed on the HP-UX operating system support long host names. The length has been extended to 255 bytes, in any combination of characters or digits. The minimum operating system requirement is HPUX 11iv2 (and above).

To enable long host name support, complete the following tasks:

Turn on the kernel tunable parameter expanded_node_host_name.
```
 Kctune expanded_node_host_name=1
```
Compile applications requiring long host name support with the -D_HPUX_API_LEVEL=20040821 option.

Mounting considerations

For root installations of DB2 products on UNIX operating systems, do not mount your file system with the nosetuid option.
