Can a GUP be updated manually using definitions files in a manner similar to how the Intelligent Updater .exe files are designed to update SEP client and the file *. JDB can be used to update the virus definitions for Symantec Endpoint Protection Manager ?
The GUP process is essentially a file serving proxy component of a SEP client, it does not build deltas but only requests and caches files that clients are requesting to use in their update process from the SEPM itself. Even the GUP client itself updates by requesting files be sent from the SEPM to the GUP process.
The GUP needs to download definitions on-demand for itself for any clients configured to update through it. The GUP will cache all downloaded content according to the settings in its LiveUpdate policy and requests of SEP clients.
The Intelligent Updater .exe files are designed to update SEP client installs only. These files do not contain the required files needed by a SEPM to additionally update any clients attached.
The file *. JDB can be used to update the virus definitions for Symantec Endpoint Protection Manager only.
The SEP client software on a GUP system can be updated using the Intelligent Updaters available from Security Response however these do not apply to the GUP process itself nor does any information get cached for other clients to use for updating by this methodology.
