DB2: System Requirements

Verify that your environment meets the system requirements for DB2.

Operating System

Important

Use the most recent version of the operating system that is listed. The Commvault software fully supports the most recent version of an operating system, until the vendor ends support. More recent versions of the Commvault software might not install on operating systems that are not supported by the vendor anymore. For information about the support lifecycle of an operating system, contact the vendor.

Clustering

If clustering is supported by the operating system, you can install the software on a cluster. For information about supported cluster types, see Support for Cluster Configuration.

Software That Is Automatically Installed

.NET Framework

On most versions of Windows, the .NET Framework 4.7 is automatically installed.

Microsoft Visual C++ Redistributable 2017

Starting with Service Pack 18, Microsoft Visual C++ Redistributable 2017 (vcredist2017.exe) is automatically installed.

If a computer does not have the most recent Windows updates, the installation of Microsoft Visual C++ Redistributable 2017 will fail in installing Universal C Runtime. The following Windows updates must be installed to prevent the installation failure. The updates are not required on the most recent Windows operating system versions, such as Microsoft Windows 10 and Microsoft Windows Server 2016, because these versions have the Universal C Runtime already installed.
