Setting Definition Files
Some Device Servers are unable to provide AggreGate Server with information about their internal settings. To make configuration of these Device Servers possible, AggreGate Server uses Setting Definition Files (SDF files). Each SDF file contains a list of settings supported by Device Servers with a particular firmware version. SDF files are shipped as part of the AggreGate Server distribution package and installed into the /sdf subfolder of the AggreGate Server installation. All SDF files are loaded in memory during startup. If some changes are made to one of the existing files or new files are added, it is necessary to restart server to activate them.
When a user upgrades the firmware for old Device Servers, they may need to receive a new SDF file(s) from Tibbo and put it in the /sdf folder. This will allow them to access settings available in newer Device Server firmware versions.
 | The average AggreGate Server user (or even administrator) will never have any actual contact with the SDF files. You can consider this topic as an "in-depth" topic, for extending your understanding of AggreGate Server internals. |
