Configuring Orchestration Server

[New Page]

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

• Each SIP Cluster node (SIP Server) has to 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 has to be provisioned in the ORS options, section gts.

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 as shown below 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)
