DB2 10.5 for Linux, UNIX, and Windows

Additional installation considerations (Solaris)

Before you install a data server 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.

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

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 data 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.
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 data server product

Security patches can be obtained from the http://java.sun.com website. From the SunSolve online website, click Patches in the left panel.

The Java2 Standard Edition (J2SE) Solaris Operating System Patch Clusters and the SUNWlibC software are also required and can be obtained from the http://java.sun.com website.

The Fujitsu PRIMEPOWER patches for the Solaris Operating System can be downloaded from FTSI at: http://download.ftsi.fujitsu.com/.

Data server database products support the following Solaris concepts:

Solaris Logical Domains (LDoms)
Solaris Zones
ZFS filesystems

For details about virtualization technology supported by data server products, see https://www.ibm.com/developerworks/community/wikis/home?lang=en#!/wiki/Information%20Management/page/Virtualization.

Mounting considerations

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