Working with your new deployment managers

Once you complete the customization instructions, you will have a WebSphere® Application Server for z/OS® Network Deployment cell. The Network Deployment cell consists of a deployment manager and a location service daemon. (To run Java™ EE applications, you must add application server nodes. See below for details.) This article provides useful information for working with your new Network Deployment cell.

Before you begin

Make sure that the WebSphere Application Server for z/OS product HFS and configuration HFS are mounted.

Procedure

  1. To start your deployment manager, issue the following MVS™ console command:
    START server_proc,JOBNAME=dmgr_name,ENV=cell_name.node_name.dmgr_name
    where:
    • server_proc is the deployment manager controller cataloged procedure.
    • dmgr_name is the deployment manager short name.
    • node_name is the deployment manager node short name.
    • cell_name is the cell short name.
    If you chose default values, for example, you would enter the following START command:
    START BBO7DCR,JOBNAME=BBODMGR,ENV=BBOCELL.BBODMGR.BBODMGR
    The START command brings up the deployment manager controller. The controller starts the location service daemon, then uses WLM to start the deployment manager servant. You should see a message similar to the following when the deployment manager is up and running:
    BBOO0019I INITIALIZATION COMPLETE FOR WEBSPHERE FOR Z/OS CONTROL PROCESS BBODMGR
  2. Once the deployment manager is successfully started, access the administrative console by pointing a Web browser to the following URL:
    http://hostname:http_port/ibm/console
    where:
    • hostname is the deployment manager HTTP transport host name that you specified during customization.
      Note: If you specified "*" for the deployment manager HTTP host name, this is actually the deployment manager node host name.
    • http_port is the deployment manager HTTP port that you specified during customization.
      Note: The default HTTP port for the deployment manager is 9060.
    Until global security is enabled, you will see a signon screen that asks you for a user ID.

    The user ID needs to be the one defined during the customization of the dmgr.

    You can use the administrative console, scripting, or both to manage the Network Deployment cell and deploy and manage Java EE applications. Before you can deploy applications, however, you need to add application server nodes to your Network Deployment cell.

  3. Add an application server node to a Network Deployment cell using one of two methods:
    • Create an (empty) managed node using the Profile Management Tool or zpmt command. The new node can reside on the same or a different z/OS system as the deployment manager. The new managed node, consisting of just a node agent and perhaps a location service daemon, is federated into the Network Deployment cell. Once this is done, you can use the administrative console or scripting to add application servers and deploy and manage Java EE applications in the node.

      See Planning for new managed (custom) nodes for more information.

    • Federate an existing standalone application server into the Network Deployment cell. The standalone server node becomes a managed node in the Network Deployment cell, along with any Java EE applications that have been deployed on it.

      See Planning to federate standalone servers into a Network Deployment cells for more information.

    Application server nodes (also called managed nodes) in a Network Deployment cell consist of a node agent and any number of application servers per node.
    Note: Each z/OS system also needs one location service daemon for each standalone or Network Deployment cell hosted on the system.
  4. Use one of the following two methods to stop your deployment manager:
    • Stop the location service daemon, which also stops the deployment manager and any of the cell's managed nodes on the same z/OS system. The location service daemon holds pointers to modules in common storage, and stopping it forces the cell's nodes on the same z/OS system as the location service daemon to shut down. To stop the location service daemon, enter the following MVS console command:
      STOP daemon_jobname

      where daemon_jobname is the location service daemon job name. The default location service daemon job name for a Network Deployment cell is BBODMNC.

      Note: This is the easiest way to stop the deployment manager.
    • Stop just the deployment manager, leaving the location service daemon and any managed nodes on the z/OS system still running. This works because the deployment manager is used to administer only the cell--it does not need to be up for Java EE applications in the cell to run. To stop the deployment manager, enter the following MVS console command:
      STOP dmgr_name

      where dmgr_name is the deployment manager short name. The default deployment manager short name is BBODMGR.
