Before you install
data server database products on HP-UX operating systems, ensure that
the system you choose meets the necessary operating system, hardware,
software, and communications requirements. The db2prereqcheck command
checks whether your system meets the prerequisites for the installation.
For
the most up-to-date installation requirements for data server database
products, see System requirements for IBM® DB2® for Linux, UNIX, and Windows.
This techdoc uses 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 these database products.
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 client or data 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 database servers to run 32-bit non-SQL routines.
- (Clients only) If you plan to use Kerberos
authentication, your applications must be 64-bit.
- (Client and server) To use Kerberos
authentication, install the HP krb5 Kerberos support
via the Kerberos packages on the operating system.
- 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 the product.
- For details regarding known HP-UX issues, see www.ibm.com/support/docview.wss?uid=swg21257602
Note: Data
server 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.
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 data server products on UNIX operating
systems, do not mount your file system with the nosetuid option.
