Configure cells
This topic describes how to change the cell protocol information, define custom properties for the cell, and add additional nodes. Before you can configure cells, install the WAS ND.
When you create a dmgr profile, a cell is created. A cell provides a way to group one or more nodes of your WAS ND. 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 admin console.
- If the protocol that the cell uses to retrieve information from a network is not appropriate for the 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 change the cell protocol configuration from TCP.
- Click Custom Properties and define any name-value pairs that your dmgr needs.
- Click New.
- Specify a name and value for the custom property.
- When you install the WAS ND product, a node may have been added to the cell. We can add additional nodes on the Node page. Click Nodes to access the Node page, which you use to manage nodes.
Both Internet Protocol Version 4 (IPv4) and IPv6 (IPv6) are now supported by WAS, but there are restrictions that apply to using both IPv4 and IPv6 in the same cell. Note that when you add a node to a cell, the format in which you specify the host name is based on the version of IP the node will be using. For further information, read the topic on 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
We can continue to administer your WAS ND by doing such tasks as managing nodes, node agents, and node groups.
