System requirements for IBM Db2 for Linux, UNIX, and Windows

Detailed System Requirements


Abstract

This document describes the system requirements for IBM® Db2® for Linux®, UNIX®, and Windows®.

Content

The detailed system requirements information is the complete list of hardware requirements, supported operating systems, prerequisites and optional supported software, with component-level details and operating system restrictions.

Hardware Embedded Full Virtualization Environment

Db2 supports hypervisors being fully embedded in hardware and firmware while operating system requirements are met. Some examples are systems equipped with Power Hypervisor, VMware ESX 3i, or Hitachi Virtage.

Note: Any enhancements in hypervisor function that come in the form of separate software are not included in the definition of Hardware Embedded.

Virtualization and Db2 V11.5

Db2 V11.5 (non-pureScale) runs on any operating system (OS) that is virtualized by any virtualization technology. Hypervisors in use must run a supported enterprise OS (For example, KVM with RHEL Enterprise support. KVM running CentOS is not recommended).

OS virtualization that supports Db2 V11.5 is available to enterprise-ready and licensed hypervisors with the write-thru feature enabled.

Note: This statement does not apply to Db2 pureScale clusters in any Db2 releases. For a detailed list of supported virtualization for pureScale, refer to the reports for each release.

If IBM believes that an issue is specific to a virtualization technology (such as performance or communication with peripheral and hardware components), IBM might require that the customer reproduce the issue in a nonvirtualized configuration.

Due to the nature of virtualization technologies, IBM cannot guarantee levels of performance that are impacted by a customer’s virtualized deployment. Similarly, IBM cannot guarantee resolutions to issues that are caused by a customer’s virtualized deployment.
Virtualization for Db2 V11.1 and earlier releases

For releases before V11.1,  see the reports for each individual release.  The hypervisors must be running on hardware supported by the level of Db2 being used. The provided guest host OS level must be supported by the level of Db2 being run. 
The supported hypervisors for pureScale configurations are different from those used for non-pureScale configurations. Ensure that you select the hypervisor that is right for you. 
Operating system considerations for Db2 V10.5

Operating system (OS) support for Db2 Version 10.5 is not available for OS levels that were released after 30 April  2020, the database product's end-of-service (EOS) date. Db2 V10.5 is now in its extended support phase.
