The policy_type value
is not case sensitive. The failover, wlor,
or wrr values can be specified in uppercase
or lowercase.
Valid values:
failover:
When a request for the application Web module in the cell that is
specified in the Name field fails, the request
fails over to the cell and cluster that are specified in the Value field
after the @ symbol. Requests route only to the configured
cell and cluster when the primary cell is down. The cell status is
indicated by an HTTP status code of 503, service unavailable.
wlor:
Specifies a weighted least outstanding request load balancing policy.
This policy comes into effect when the ODR is active and reads its
custom property configuration. This load balancing policy not only
considers weights, but also how many outstanding HTTP requests exist
in a cluster. This policy will more efficiently distribute requests
to clusters that can handle them. wlor is recommended
over wrr.
New weight values are obtained
every 15 seconds from the dynamic workload manager (DWLM), which takes
into account the application level response time. Use the mcrp.ui system
property to set the new update time in seconds. Note: The default
behavior of the ODR is to perform wlor load balancing across cells
and clusters if a request does not match an existing ODR routing rule
or if no ODR routing rules exist
wrr:
Specifies a weighted round-robin load balancing policy. This policy
comes into effect when the ODR is active and reads its custom property
configuration.
New weight values are obtained every 15 seconds
from the dynamic workload manager (DWLM), which takes into account
the application level response time. Use the mcrp.ui system
property to set the new update time in seconds
