DB2 Version 10.1 for Linux, UNIX, and Windows

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

Before you install a DB2® database product on Solaris, ensure that your system meets the operating system, hardware, and software requirements. The db2prereqcheck command checks whether your system meets the prerequisites for the installation.

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.

Table 1. Solaris installation requirements
Operating System	Hardware
Solaris 10 64- bit kernel Update 9	UltraSPARC or SPARC64 processors
Solaris 10 64- bit kernel Update 9	Solaris x64 (Intel 64 or AMD64)

Support is only for the DB2 product to be installed on either local zone or global zone. When installed in the global zone, it can be shared by other zones.

Kernel configuration considerations

The kernel configuration parameters are set in /etc/system. 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. These parameters must be set before you install an IBM data server client.

Software considerations

libpam.so.0 (32-bit) is required for DB2 database servers to run 32-bit non-SQL routines.
(Client and server) To use Kerberos authentication, install the krb5 Kerberos support via the available Kerberos packages. For more information about installing Kerberos for Solaris, see Installing and configuring Kerberos.
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

Mounting considerations

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