Parameters
facility_name
Specifies the name of the facility to be extended.
Any application program which uses this facility must specify the same name
when it calls the
Facility names can contain up to thirty-one characters. Letters, numbers and
underline characters are all valid, but the first character of a facility name must
be a letter.
The default value for
The
/ROUTER
specified.
An EXTEND FACILITY command executed on a node where the facility is not
defined is interpreted as a CREATE FACILITY command.
To maintain consistency in a facility, the following rules apply when adding nodes
or roles or both:
If a frontend role is added, then the node where it is added must know about
at least one router of the facility.
If a backend role is added, then the node where it is added must know about
all routers of the facility. If any router nodes are not known by a backend,
then problems may occur in achieving quorum.
If a router role is added, then the node upon which it is added must know
about all backends of the facility. If not all backend nodes are known by a
router, then problems will occur in achieving quorum. At least one frontend
must be defined on a node that has the router role.
In order to have a consistent facility definition across all nodes in the facility
(and thus avoid problems in attaining quorum), the command to add a router
role must be executed on all relevant nodes, that is, the node gaining the
router role and all backend nodes.
Qualifiers

facility.
