Configuring Orchestration Server

[New Page]

To configure ORS for use in a SIP Cluster environment, ensure the following:

• Each SIP Cluster node (SIP Server) must be served by a dedicated Orchestration cluster.
• All ORS servers must use only the default port of SIP Server for connectivity.
• The cluster-skip-cfg-event=0 option must be configured in the gts section of the ORS application.

Configuring ORS to Reduce URS CPU Usage

URS CPU usgae can be reduced to improve performance if required, by:

• Disabling registration of VQ DNs on ORS.
• Having certain SCXML functions to be executed in ORS instead of URS.

The following options must be configured to reduce URS CPU usage:

• [orchestration]\support-dn-type-5=0 (to prevent ORS from registering VQ DNs)
• [orchestration]\functions-by-urs=false (to enable some SCXML functions to be executed on ORS instead of URS)
