Managing Serviceguard Sixteenth Edition, March 2009

These parameters are optional, but if they are
defined, WEIGHT_DEFAULT must follow
WEIGHT_NAME, and must be set to a
floating-point value between 0 and 1000000. If
they are not specified for a given weight,
Serviceguard will assume a default value of zero
for that weight. In either case, the default can be
overridden for an individual package via the
weight_name and weight_value parameters in the
package configuration file.
For more information and examples, see
“Defining Weights” (page 179).
IMPORTANT: CAPACITY_NAME,
WEIGHT_NAME, and weight_value must all
match exactly.
NOTE: A weight (WEIGHT_NAME,
WEIGHT_DEFAULT) has no meaning on a node
unless a corresponding capacity
(CAPACITY_NAME, CAPACITY_VALUE) is
defined for that node.
For the reserved weight and capacity
package_limit, the default weight is always
one. This default cannot be changed in the cluster
configuration file, but it can be overridden for
an individual package in the package
configuration file.
cmapplyconf will fail if you define a default
for a weight but do not specify a capacity of the
same name for at least one node in the cluster.
You can define a maximum of four
WEIGHT_DEFAULTs per cluster.
Can be changed while the cluster is running.
Access Control Policies (also known
as Role Based Access)
For each policy, specify USER_NAME,
USER_HOST, and USER_ROLE. Policies set in the
configuration file of a cluster and its packages
must not be conflicting or redundant. For more
information, see “Setting up Access-Control
Policies” (page 226).
