Oracle MDS Remote File Service

The MDS remote file server:

Oracle MDS FTP Service

The MDS FTP (file transfer protocol) service performs binary file transfers between
the MDS and FTP clients on remote computers. A single MDS FTP service runs on
the video server computer. The MDS FTP service listens for requests from remote
clients on a dedicated port.
The MDS FTP service only accesses files in the MDS, not on the video server
computer host file system. Host files can be accessed through the video server
computer host FTP service which listens for requests on a different dedicated port.

HSM Service

The HSM (hierarchical storage management) server controls access to files in
tertiary storage and manages their layout in a way similar to how the MDS
directory server manages files in the MDS.

HSM Transfer Service

The HSM transfer service copies files between tertiary storage and MDS volumes
on disk when requested by an HSM utility.

Stream Service

The stream service handles requests from clients for video and audio content.
When the stream service receives a request, it obtains necessary information to
meet the request:
The stream service tells the video pump which parts of the physical content files to
play.
provides access to MDS files for remote processes such as MDS utilities and
applications on remote computers
delivers BLOBs to clients on request
The stream service contacts the content service to resolve a request for a logical
content title to one or more tag files.
The stream service reads the tag file(s) associated with the request. Each tag file
describes which portion of a requested file must be delivered to meet the
request.
