You can use iSeries™ Navigator on your server to collect and manage various inventories on a regular basis, and store the data on a designated central system.
You can collect the inventory for users and
groups, fixes, system values, hardware resources, software resources, service
attributes, contact information, or network attributes. You may have other
applications installed that allow you to collect lists of other types of resources. 
You can share this information with IBM® through Electronic Service Agent™. This enables IBM to help you identify problems and troubleshoot them more quickly. In some cases, sharing your inventory can help you avoid a problem altogether. For example, you share your software inventory with IBM and a fix becomes available for a software product that you have installed. Depending on the connectivity options you've selected, you can receive the fix automatically, which can help you to avoid a problem before you even experience it.
