Restarting the DSS server
To force the DSS server to restart, select Configuration
Data Transfer
→
→
DSS
Restart DSS Server
→
, and click the Yes button. This action will
immediately kill any running DSS servers, and currently-activated subscriptions
will be terminated without notice. Clients will have to register with the new
instance of
dssserver
before they can continue receiving data.
SEED
The DCM can compile full SEED volumes in real time. To enable this, select
yes for the disk.recordas.seed option under Configuration
Disk
→
(see above.)
A configuration file,
/etc/seed.cfg
, is provided allowing you to provide
technical information about the streams to be recorded in SEED format. The
DCM will only write SEED volumes for streams mentioned in this file.
Clicking SEED configuration brings up a page in the work area which enables
you to edit the file and its attributes directly.
