Wild Cards
Some subsystems support the use of a wild card (*) in object names. If you use a wild
card, it is resolved by the subsystem and not from DNS. Therefore, any object
specification that contains a wild card must be accompanied by qualifiers that enable
DSNM to determine the subsystem, object type, manager (if any), and node.
This does not always mean that all qualifiers must be entered. The manager must
always be specified if it is required by the subsystem, but DSNM or the subsystem can
provide values for missing qualifiers:
If there is no node qualifier, DSNM assumes the local node.
If there is no subsystem qualifier but the manager is specified, DSNM attempts to
determine the subsystem from the manager, provided the manager process is
running.
If there is no object type qualifier, the subsystem applies its default object type.
Special Properties of the Node Qualifier
If the node qualifier specifies that the objects are located on a node different than the
local node, the name cannot be resolved in the local DNS database and name
resolution is attempted at the destination node.
You can specify a node qualifier with any type of name—subsystem objects, aliases,
groups, composites, or wild cards (*). It can be supplied either as part of the object
name or as part of the manager. If you supply the node qualifier as part of the
manager, it applies to all the names listed in the object specification. If the node
specified with a manager is different from the nodes specified with any of the names
in the same object specification, the manager node takes precedence and the
conflicting nodes are ignored. DSNM does not support objects that are located on a
node different from their managers.
Caution You must supply a node qualifier for object names on remote nodes.
The operating system dictates that names are names that begin with a dollar sign ($) in the local form.
Because of the way DNS stores subsystem object names, it is not possible to determine the node of an
object from DNS if its name begins with a dollar sign. Therefore, DSNM assumes that object names are
on the local node unless a node qualifier specifies otherwise.
