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 12.1 and Db2 11.5
Non-pureScale configurations of Db2 12.1 and Db2 11.5 run 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 both Db2 12.1 and Db2 11.5 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 Db2 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.
For releases before version 11.1, 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.
Db2 10.5 entered the end-of-service phase on April 30, 2020. Operating system (OS) support for Db2 10.5 is not available for OS levels that were released after this date. Db2 10.5 is now in the extended support phase.
Hardware support for Db2 editions that are not configured as Db2 pureScale clusters is determined by the hardware requirements of the operating system on which Db2 runs.
