Create multiple WS-Notification services and instantiate
WS-Notification service points on different servers in the cell depending
upon the quality of service (QoS) that is required.
About this task
WS-Notification enables partitioned topologies in which
some servers provide a different quality of service that can be used
by customers of varying status. For example you might configure a
cluster of servers for use by a particular customer in order to provide
enhanced HA facility or improved response times.
Procedure
-
Configure
a cell containing multiple servers that can support the QoS
requirements.
-
Configure
one or more service integration buses in the cell.
-
Learn about the options that exist for partitioning access
to messaging resources and defining non-overlapping WS-Notification
services.
- You can define multiple WS-Notification services on a single service
integration bus. By ensuring that topic namespaces defined by the
two (or more) services do not make use of the same service integration
bus topic spaces you can ensure that there is no possibility for communication
between the clients of respective WS-Notification services.
- You can also define multiple service integration buses and configure
a single WS-Notification service on each. The choice of which of these
two options to use depends upon the existing messaging infrastructure,
and the enterprise's policy towards creation of multiple service integration
buses.
-
Allocate service integration bus members and WS-Notification
service points to appropriate servers in the cell in order to provide
the required speed of response to requests. For example a faster response
time will require the elements to be deployed on faster (or less heavily
loaded) hardware.
-
Configure appropriate advanced settings associated with
the WS-Notification service point to provide other QoS requirements
such as security and reliability.
- For JAX-WS based Version 7.0 WS-Notification service points, attach policy sets
to the application associated with the service point to provide
these other QoS requirements. For example, the reliable secure profile
default policy sets (WS-I RSP and WS-I RSP ND) contain instances of
the secure conversation and reliable messaging policies that are configured
to work together.
- For JAX-RPC based Version 6.1 WS-Notification service points, configure the inbound ports associated
with the service point to provide these other QoS requirements.
