- Appserver Cluster
- A deployment platform for LiveCycle cluster and Author cluster.
- LC Cluster
- A deployment of clustered LiveCycle instances.
- Author Instances
- Used by an author to create assets such as text, category
and letters.
Author instances in a cluster can reside on the
same machine or different machines. For Failover support due to
hardware failure, different machines for the author instances is
recommended. In an Author cluster, one node is designated as master
and the other nodes are designated as slaves.
- Publish Instances
- Used by agents to create letters.
Publish instances
in a farm can reside on the same machine or different machines.
For Failover support due to hardware failure, different machines
for Puthor instances is recommended. Publish instances should not
to be clustered.
Note: For Author and Publish instance deployment
on an application server, it is recommended that each such instance
is deployed on a different profile. Deploying more than one Author
or Publish instance on the same profile can result in erroneous configuration.
In addition to the above mentioned deployment, each machine can host
one Author-Publish pair to save hardware cost. In this case, we
are still able to achieve failover successfully as all Autho-Publish
instances reside on different physical machines.
- LC Load Balancer
- A web server that load balances all invocations to the LiveCycle
cluster. The Author and Publish instances interact with the LiveCycle cluster
through the load balancer.
- Dispatcher
- A web server entity that load balances all requests to the
Author and Publish instances. The Dispatcher is a plug-in module
that can be used with different web servers.
Note: The LiveCycle load balancer and Dispatcher can reside on the
same physical machine or different machines. It is based on the
requirement of placing the load balancer and dispatcher within an
intranet or DMZ. You can use the same machine if the intranet and
DMZ are in the same zone. If the load balancer or dispatcher is placed
in DMZ, ensure that required ports are open for communication.
