Below are attributes for configuring an SGC Stack instance and the entire cluster.

Note
Atribute modification restrictions
  • Only attributes that are "Reconfigurable" can be modified after a configuration object is created.

  • Attributes that do not support "Active Reconfiguration" can be changed only when the configuration object is disabled (the value of its disabled attribute is false).

node

The node configuration object is for configuring an SGC Stack instance. Every SGC instance that is to be a part of cluster must be represented by a node configuration object. During startup, the SGC instance property ss7.instance is matched against the oname of existing nodes. If a match is found, the SGC instance will connect to the cluster, acting as that matching node.

9701

stack-data-address
Reconfigurable

interface where stack can connect for data connection

value of stack-http-address if defined, otherwise value of switch-local-address

stack-data-port
Reconfigurable

port where stack can connect for data connection

The TCAP Stack that is bundled with CGIN RA will use this connection to originate and receive TCAP messages.

9703

stack-http-address
Reconfigurable

interface where stack can get balancing information

The TCAP Stack that is bundled with CGIN RA will use this connection to to register with the SGC node.

value of stack-data-address if defined, otherwise value of switch-local-address

stack-http-port
Reconfigurable

port where stack can get balancing information

The TCAP Stack that is bundled with CGIN RA will use this connection to to register with the SGC node.

9702

local-configuration
Read only

node configuration

Specifies values of properties that can be defined in the SGC.properties file.

Note The JMX Object name for node is SGC:type=general,category=node

parameters
