This topic describes how to change the cell protocol information,
define custom properties for the cell, and add additional nodes.
Before you begin
Before you can configure cells, you must install the WebSphere
Application Server Network Deployment product.
About this task
When you create a deployment manager profile, a cell is
created. A cell provides a way to group one or more nodes of your
Network Deployment product. You define the nodes that make up a cell,
according to the specific criteria that make sense in your organizational
environment. You probably do not need to configure the cell again.
Administrative
configuration data is stored in XML files. A cell retains master
configuration files for each server in every node in the cell. Each
node and server also have their own local configuration files. Changes
to a local node or to a server configuration file are temporary,
if the server belongs to the cell. While in effect, local changes
override cell configurations. Changes to the master server and master
node configuration files made at the cell level replace any temporary
changes made at the node when the cell configuration documents are
synchronized to the nodes. Synchronization occurs at designated events,
such as when a server starts.
To view information about and
to manage a cell, use the settings
page for a cell.
Procedure
- Access the settings
page for a cell. Click System Administration > Cell from
the navigation tree of the administrative console.
- If the protocol that the cell uses to retrieve information
from a network is not appropriate for your system, select the appropriate
protocol. By default, a cell uses Transmission Control Protocol (TCP).
If you want the cell to use User Datagram Protocol, select UDP from
the list for Cell Discovery Protocol on the settings page
for the cell. It is unlikely that you need to change the cell protocol
configuration from TCP.
- Click Custom Properties and define any name-value
pairs that your deployment manager needs.
- Click New.
- Specify a name and value for the custom property.
- When you install the WebSphere Application Server Network
Deployment product, a node may have been added to the cell. You can
add additional nodes on the Node page. Click Nodes to access the
Node page, which you use to manage nodes.
WebSphere
Application Server on other platforms has support for Internet Protocol
Version 4 (IPv4) and Internet Protocol Version 6 (IPv6). However,
the i5/OS platform supports IPv4 only. When you add a node to a cell,
the format in which you specify the host name is based on the version
of IP that the node is using. For details, see IP version considerations for cells.
Results
Depending on which steps you performed, you changed the cell
protocol information, defined custom properties for the cell, and
added additional nodes.
What to do next
You can continue to administer your Network Deployment product
by doing such tasks as managing nodes, node agents, and node groups.
