EXTEND FACILITY

Backend-listis a list of backend-nodesseparated by commas. If there is more than one backend-node, then backend-listmust be enclosed in parentheses.

Backend-nodeis either the name of a node or @file-spec, where file-specspecifies a file containing a backend-liston each line.

/BALANCE /NOBALANCE (D)

Specifies that load balancing is enabled for frontend/router connections across the facility.

In order for load balancing to function correctly, /BALANCE must be defined on all routers, as well as on those frontends requiring load balancing.

It has no significance on a backend node, and will be ignored if specified.

The default behavior (/NOBALANCE) is for a frontend to connect to the preferred Router. Preferred routers are defined by the order specified in the /ROUTER qualifier of the EXTEND FACILITY command. Note that this preference is subject to the router being available and quorate.

For more details on frontend load balancing, see Section 2.6, Router Load Balancing.

/CALL_OUT[=role-list] /NOCALL_OUT (D)

Specifies which node types are to have call-outservers running on them.

Role-listis a comma separated list of roles. If role-listcontains more than one role then it must be enclosed in parentheses.

Role is one of the keywords ROUTER or BACKEND.

The default for role-list is (ROUTER,BACKEND).

/CLUSTER /NOCLUSTER (D)

Specifies that the command is executed on all the nodes in the cluster.

If neither /NODE nor /CLUSTER is specified then the command is executed on the nodes specified by the latest SET ENVIRONMENT command. If no SET ENVIRONMENT command has been entered then the command is executed only on the node where the command was issued.

Note: In environments that do not support clustering, use of the /CLUSTER qualifier will cause the relevant command to be executed on the local node only.

/FRONTEND=frontend-list /NOFRONTEND (D)

Specifies the names of the added nodes that act as frontends in this facility. Frontend-listis a list of frontend-nodesseparated by commas. If there is more than one frontend-node, then frontend-listmust be enclosed in parentheses.

Frontend-nodeis either the name of a node or @file-spec, where file-specspecifies a text file containing a frontend-liston each line.

/NODE[=node-list] /NODE=default-node-list (D)

Specifies that the command is executed on all nodes specified in node-list. If node-listis omitted then the command is executed only on the node where the command was issued.
