Controlling Clip Mirror Operation
007-4403-003 127
Parameter vtr.clipmirror.local_server.hostname
The vtr.clipmirror.local_server.hostname control specifies the name of the
network interface alias for transfers between the primary SGI Media Server and the
mirror. A primary SGI Media Server may possess multiple network interfaces, each
described by a static IP address and name alias. This control routes clip content network
traffic over a specific interface from the primary SGI Media Server to the mirror platform.
Clip content transfers use the default network interface configured by the primary
SGI Media Server at bootstrap. Use this parameter to establish an alternate, exclusive
interface for clip transfers.
Changing this control using the SSET command does not have an immediate effect. The
clip mirror process on the SGI Media Server must be stopped and restarted using
vtrstart –f for the new value to become active.
Parameter vtr.clipmirror.max_threads
The vtr.clipmirror.max_threads control parameter specifies the number of
concurrent mirror operations supported by the mirror platform. The value specified by
this control should be calculated from the network connection throughput and the
real-time filesystem resource on the primary SGI Media Server; the default is 20 with a
minimum of 1 and maximum of 100. Using a value of 1 for this control severely
constrains mirror operations especially when used for high-content capture on the
primary SGI Media Server.
Changing this control using the SSET command does not have an immediate effect. The
clip mirror process on the SGI Media Server must be stopped and restarted using
vtrstart –f for the new value to become active.
Parameter vtr.clipmirror.reconnect_interval
The vtr.clipmirror.reconnect_interval establishes a polling interval for
connection attempts by the mirror platform to the primary SGI Media Server. The default
value is 30 seconds, and 1 second is the minimum possible. Should the primary
SGI Media Server cease service, the mirror platform will continue connection attempts
until service resumes.
