In Command Central, you install products (9.8 and later) and fixes (9.7 and later) from repositories.

The Software AG Software Download Center (SDC) hosts repositories that contain all Software AG products. The Empower Product Support website hosts repositories that contain all Software AG fixes. On your Gateway Command Central, you define a connection from the local Platform Manager to these repositories. This connection enables you to install products and fixes on target installation machines. The connection also enables you to create mirror repositories from which to install products and fixes on target installation machines in distant locations or in environments that do not have Internet access.

On the Gateway Command Central, you first create mirror repositories that serve as the primary source of products and fixes you have licensed. From non-Gateway Command Centrals, you then connect to the Gateway Command Central and create secondary mirror repositories from the primary mirror repositories.

From any Command Central, you can connect to mirror repositories that are managed by another Command Central to install products and fixes. For example, you might want to connect from a Command Central in a production environment to a Command Central in a test environment to re-use product and fix binaries that have been tested and are ready for production.

If a non-Gateway Command Central cannot connect to the Gateway Command Central, you use image repositories to install products and fixes. An image repository is a product installation image you create using Software AG Installer, or a fix installation image you create using Software AG Update Manager, and then upload to Command Central. For example, if your production environment has no Internet access, you would create an image repository in your test environment, upload it to the Command Central in the production environment, create a mirror repository using the image repository as source, and then install from the mirror repository.
