Configure cells
When creating a deployment manager profile, a cell is created. A cell provides a way to group one or more nodes of our WAS ND product. We can change the cell protocol information, define custom properties for the cell, and add additional nodes.
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 manage a cell, use the settings page for a cell.
Tasks
- Access the settings page for a cell.
From the navigation tree of the administrative console click...
System administration > Cell
- By default, a cell uses Transmission Control Protocol (TCP). We can 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 will need to change the cell protocol configuration from TCP.
- Click Custom Properties and define any name-value pairs that the deployment manager needs.
- Click New.
- Specify a name and value for the custom property.
- When we install the WAS ND product, a node may have been added to the cell. We can add additional nodes on the Nodes page. Click Nodes to access the Nodes page, which we use to manage nodes.
Both Internet Protocol Version 4 (IPv4) and Internet Protocol v6 (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 we add a node to a cell, the format in which we 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.
Depending on which steps we performed, we changed the cell protocol information, defined custom properties for the cell, and added additional nodes.
What to do next
Manage nodes, node agents, and node groups.
