If a node group becomes overloaded and needs more servers, Tivoli
Intelligent Orchestrator can obtain more physical computing resources from
servers that are outside the node group. When WebSphere Extended Deployment
needs more servers, Tivoli Intelligent Orchestrator can automatically install
WebSphere Extended Deployment on outside servers and configure the server
network connectivity.
Before you begin
Tivoli Intelligent Orchestrator and WebSphere Extended Deployment
must be installed.
About this task
Use Tivoli Intelligent Orchestrator with WebSphere Extended Deployment
to obtain more physical computing resources from outside a node group. You
can share servers among multiple application environments with multiple WebSphere
Application Server cells or environments that are not using WebSphere software.
Tivoli Intelligent Orchestrator can be useful in complex situations, such
as when sharing resources between a WebSphere Extended Deployment Version
6.0 system and other data center systems, or when two different applications
that are installed on two different dynamic clusters backed by different node
groups require different access to resources in the data center.
Procedure
- Verify that every node in the WebSphere Extended Deployment configuration
belongs to at least one node group that is not the DefaultNodeGroup node group.
By default, new nodes are added to the DefaultNodeGroup node group.
However, dynamic clusters cannot be backed by the DefaultNodeGroup node group.
Tivoli Intelligent Orchestrator cannot manage the DefaultNodeGroup node group.
- Install the was-xd.tcdriver driver. See Installing the WebSphere Extended Deployment driver into Tivoli Intelligent
Orchestrator
for
more information.
- Create a WebSphere Extended Deployment model in the Tivoli Intelligent
Orchestrator data center model. See Configuring WebSphere Extended Deployment in the Tivoli Intelligent
Orchestrator data center model
for
more information.
- Set the properties that WebSphere Extended Deployment requires.
See Configuration properties for Tivoli Intelligent Orchestrator
for more information.
- Optional: Configure Tivoli Intelligent Orchestrator
to use silent installation to automatically provision nodes to WebSphere Extended
Deployment. If you are using Tivoli Intelligent Orchestrator to
automate only part of the work, for example, adding nodes into a node group,
you can install WebSphere Extended Deployment manually. See Silent installation
for
more information.
With WebSphere Extended
Deployment Version 6.0.1 or later, you can create a file repository to hold
your installation images instead of creating an installation image on each
node. See Configuring a Tivoli Intelligent Orchestrator file repository
for more information.
- Configure the WebSphere Extended Deployment installation in the
Tivoli Intelligent Orchestrator data center model. You can create
a data center model in the following ways:
Results
Tivoli Intelligent Orchestrator can obtain more physical computing
resources when WebSphere Extended Deployment needs more servers.
