dataserver
The dataserver process provides all interaction with the TX/MAM (asset info) and Playout (schedule
info) database files. The dataserver retrieves information from and updates information in the
databases.
The dataserver uses a watchdog process that checks the database connection. This service is called:
pt_guard. As a default, pt_guard checks the connection every 10 seconds. When a 15 seconds
timeout is reached, pt_guard will restart the dataserver process.
nexusproc script
Use the nexusproc script to manage the Cobalt services.
Logs
To check the dataserver logs:
# tail –f /var/log/dsYYYYMMDD.log
(For example ds20110823.log.)
Configuration
The dataserver is not configured itself but uses configuration information from POC.
Applets
Retrieving data from the dataserver is done by means of XMLRPC calls. XMLRPC is an industry
standard used to invoke functions across a network. A detailed description can be found on
www.xmlrpc.com .
To access the dataserver using applets or Linux-applications, a library (libcobalt.so) is available. For
more information, please contact Support.
If in POC an active Playlist's clock is displayed in red, the dataserver service is not available and
needs to be restarted.
Example dataserver not running or accessible.
