Configuring Orchestration Server

[New Page]

The cluster-skip-cfg-event=0 option must be configured in the gts section of the ORS application.

[Val asks: I don't see such section and option in the running ORS in the SIP Cluster. Please confirm with the team.]

Deploy ORS applications as an HA pair, Warm Standby redundancy mode, by following the standard procedure. Each SIP Cluster Node must be served by a dedicated Orchestration cluster.
- Suggested application names: ORS_<datacenter>_1, ORS_<datacenter>_1_B.
On the Connections tab, add the following connections:
- confserv_proxy_<datacenter>—Set to the following parameters:
  - Connection Protocol: addp
  - Trace Mode: Trace On Both Sides
  - Local Timeout: 43
  - Remote Timeout: 81
- MessageServer_<datacenter>—Set to the following parameters:
  - Connection Protocol: addp
  - Trace Mode: Trace On Both Sides
  - Local Timeout: 7
  - Remote Timeout: 11
- SIPS_<datacenter>_1 (the primary SIP Server, the default port)—Set to the following parameters:
  - Connection Protocol: addp
  - Trace Mode: Trace On Both Sides
  - Local Timeout: 7
  - Remote Timeout: 11
- SIPS_VQ_<datacenter> (the VQ SIP Server, the default port, located in the same data center as ORS)—Set to the following parameters:
  - Connection Protocol: addp
  - Trace Mode: Trace On Both Sides
  - Local Timeout: 7
  - Remote Timeout: 11
- URS_<datacenter>_1 (the primary URS)—Set to the following parameters:
  - Connection Protocol: addp
  - Trace Mode: Trace On Both Sides
  - Local Timeout: 7
  - Remote Timeout: 11
On the Options tab, configure the following options ....

Configuring ORS to Reduce URS CPU Usage

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

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)
