DB2 Version 10.1 for Linux, UNIX, and Windows

Installation requirements for DB2 database products

Before you install your DB2® database product, ensure that the system you choose meets the necessary operating system, hardware, software, communications, disk and memory requirements. The db2prereqcheck command checks whether your system meets the prerequisites for the installation. For more information, see topic Checking installation prerequisites with db2prereqcheck.
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.
