While this overview is accurate and helpful, I strongly recommend consulting the Caché Installation Guide before beginning the installation process, and having it at hand while installing.

There are a number of things to consider for each platform (Windows, OpenVMS, UNIX®/Linux, and Mac) before you install; the install guide covers general preparation in the chapter for each platform, and also includes appendixes on system parameters for OpenVMS and UNIX®/Linux, preparing for Caché security, and file system and storage recommendations. (There is also a chapter on upgrading Caché.)

There are also a lot of options to choose among during the installation process and it useful to have the explanations available when deciding.

Finally, the install guide offers alternatives to interactive installation, including unattended installation on Windows and on UNIX®/Linux systems and the use of the %Installer class with an installation manifest.

OpenVMS note: the SET FILE/ATTRIB command cited by Richard, which may be necessary to restore to the install package attributes that were stripped when it was conveyed to the target system, was recently updated, as follows:

$ SET file/attrib=(rfm:var,mrs:32256,lrl=32256,rat=none) cache-2016.1.0.657.0-alphavms.bck
