d. If the SMP351 does not appear in the capture agents list, verify that the Opencast
server system user name, password, and core address are correct in the settings
in the Opencast Scheduling tab of the Schedule Settings page in the
SMP351. Confirm whether the other URLs (for status, recordings, configuration,
schedule, and so forth) require custom settings and update the URLs if needed.
e. Click Save. The unit name of the SMP now appears in the list of capture agents in
the Opencast server system.
A Note on Using the SMP With an Opencast server System
The SMP supports HTTP ETags (entity tags), which make it possible to cache some
scheduling information to minimize network traffic. When the SMP requests schedules from
the Opencast server system, the Opencast server server sends an ETag parameter to the
SMP. Each time the SMP and Opencast server exchange schedule information, the system
reads the ETag and determines whether there were any changes to scheduled events since
the last synchronization.
• If there have been no changes, then less scheduling data is exchanged between the
SMP and the server, which reduces network traffic and the time needed for schedule
updates.
• If changes have been made, the Opencast server server issues a new ETag, and the
SMP updates its schedules.
