Configuring cells

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

  1. Access the settings page for a cell. Click System Administration > Cell from the navigation tree of the administrative console.
  2. 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.
  3. Click Custom Properties and define any name-value pairs that your deployment manager needs.
    1. Click New.
    2. Specify a name and value for the custom property.

      The IBM_CLUSTER_RIPPLESTART_NOTIFICATION_TIMEOUT custom property:

      Specify a value, in milliseconds, to indicate the amount of time the ripplestart function waits for processes to shut down before restarting them. If you attempt a ripplestart and the processes have not shutdown before the start operation begins, one or more of the processes will not restart.

      Property IBM_CLUSTER_RIPPLESTART_NOTIFICATION_TIMEOUT
      Data type integer
      Default 300000 milliseconds (5 minutes)

      The com.ibm.websphere.management.launcher.options custom property:

      Specify a value of displayServerInFront to display the name of the cell, node, and server in front of the output for the ps -ef command. Use of this property is intended to help you identify the process ID of a server. The property has no impact on the server process.

      Property com.ibm.websphere.management.launcher.options
      Data type String
      Default None
  4. 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.

    [AIX HP-UX Linux Solaris Windows] Both Internet Protocol Version 4 (IPv4) and Internet Protocol Version 6 (IPv6) are now supported by WebSphere Application Server, 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 details, see IP version considerations for cells.

    [i5/OS] 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.
