Hardware and operating system requirements

Ensure that you meet the operating system and hardware requirements for Informix® Version 12.10.

Before you upgrade or migrate to the current version of Informix, ensure that the system you choose meets the necessary operating system, hardware, disk, and memory requirements.

For a complete list of supported operating systems and hardware prerequisites for Informix, go to http://www.ibm.com/support/docview.wss?uid=swg27013343.

If you are running an earlier version of Informix on an operating system that is no longer supported, you must migrate to a supported operating system.

Your hardware must support the operating systems that Informix Version 12.10 supports, and it must provide enough disk space for the database server and all your other software applications.

Check the machine notes for information about the operating-system patches that you need for successful installation and operation of the database server. Follow any platform-specific instructions in the machine notes.

UNIX, Linux: You might have to change some of the kernel parameters for your UNIX or Linux operating system before you install Informix Version 12.10. Refer to the kernel-configuration instructions for your operating system.
