Working with your new managed server nodes

Once you complete the customization instructions, you will have a WebSphere® Application Server for z/OS® application server node (managed node) in your 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. Start your node agent by issuing the following MVS™ console command:
    START server_proc,JOBNAME=nodeagent_name,ENV=cell_name.node_name.nodeagent_name
    where:
    • server_proc is the node agent cataloged procedure.
    • nodeagent_name is the node agent short name.
    • node_name is the node short name.
    • cell_name is the cell short name.
    If you chose default values for example (your sysplex is named CELL1 and your system is named MVSA), you would enter the following START command:
    START BBO7ACR,JOBNAME=BBON001,ENV=CELL1.MVSA.BBON001
    The START command brings up the node agent. The node agent starts the location service daemon (if one is not already running). You should see a message like the following when the node is up and running:
    BBOO0019I INITIALIZATION COMPLETE FOR WEBSPHERE FOR z/OS CONTROL PROCESS BBON001The node agent must be running in order for the deployment manager to administer
    the node.
  2. When the deployment manager for the cell is up and running, 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 administrative security is enabled, you will see a signon screen that asks you for a user ID but no password.

    The user ID can be anything and is used only to provide basic tracking of changes. Be aware that until you enable administrative security, anyone with a Web browser and access to the HTTP port can modify your application serving environment.

    You can use the administrative console, scripting, or both to manage the node and deploy and manage J2EE applications. Before you can deploy applications, however, you need to add application servers to your managed node.

  3. Application servers can be added to the managed server node using the administrative console or scripting. You can use one of the following methods:
    • Create a new application server directly using the administrative console or scripting. You can use the controller, servant and CRA cataloged procedures and user IDs created during the managed node setup process for any application servers you create in the managed node. However, after you create additional application servers in an existing node, you must run the following RACF commands:
      RDEFINE STARTED new_server_short_nameA.* STDATA(USER(controller_region_userid) GROUP(configuration_group))
      RDEFINE STARTED new_server_short_nameS.* STDATA(USER(servant_region_userid) GROUP(configuration_group))
      
      RDEFINE SERVER CB.*.new_cluster_transition_name.* UACC(NONE)
      RDEFINE SERVER CB.*.new_cluster_transition_nameADJUNCT.* UACC(NONE)
      
      PERMIT CB.*.new_cluster_transition_name.* CLASS(SERVER) ID(servant_region_userid) ACC(READ)
      
      PERMIT CB.*.new_cluster_transition_name.* CLASS(SERVER) ID(controller_region_userid) ACC(READ)
      PERMIT CB.*.new_cluster_transition_nameADJUNCT.* CLASS(SERVER) ID(controller_region_userid) ACC(READ)
      
      SETROPTS RACLIST(STARTED) GENERIC(STARTED) REFRESH
      SETROPTS RACLIST(SERVER) GENERIC(SERVER) REFRESH
    • Cluster an existing application server in another node, using this managed node as a target. This action creates a "cloned" copy of the application server being clustered in your new managed node.
  4. To start one of your managed node's application servers, issue the following MVS console command:
    START server_proc,JOBNAME=server_name,ENV=cell_name.node_name.server_name
    where:
    • server_proc is the application server agent cataloged procedure (can be the same as the node agent cataloged procedure).
    • nodeagent_name is the application server short name.
    • node_name is the node short name.
    • cell_name is the cell short name.
    If you chose the default procedure name for example (your sysplex is named CELL1, your node is named MVSA, and your server is named AZSR01A), you would enter the following START command:
    START BBO7ACR,JOBNAME=AZSR01A,ENV=CELL1.MVSA.AZSR01A
    The START command brings up the application server controller. The controller starts the location service daemon (if one is not already running) and then uses WLM to start the control region adjunct and the servants. You should see a message similar to the following when the node is up and running:
    BBOO0019I INITIALIZATION COMPLETE FOR WEBSPHERE FOR Z/OS CONTROL PROCESS AZSR01A
  5. Use one of the following two methods to stop your deployment manager:
    • Stop the location service daemon, which also stops any of the cell's nodes on the same z/OS system. The location service daemon holds pointers to modules in common storage, and stopping it forces all cell members on the same z/OS system as the 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.
    • Stop just the node agent and its application servers while leaving the location service daemon, deployment manager (if present), and any other managed nodes on the z/OS system still running. To stop the node agent, enter the following MVS console command:
      STOP nodeagent_name
      where nodeagent_name is the node agent short name. The default node agent short name is BBON001.
