Register host computers with job managers

We must register a remote host computer with a job manager to enable the job manager to access applications, command files, and other resources on the host computer.

Create a job manager profile and start the job manager.

A remote host target is not required to have any WAS products installed. There are no software requirements for this host beyond its operating system.

To register remote hosts, you can use the Targets page of an administrative console or the wsadmin registerHost command.

Procedure

• Use the Targets page of the job manager console or the dmgr console to register hosts.

  1. Click Jobs > Targets > New Host.

  2. On the New target page, specify parameters that identify the remote host and specify security information.

     1. Specify the host computer name in one of the following formats:
        • Fully qualified domain name servers (DNS) host name string, such as xmachine.manhattan.ibm.com
        • Default short DNS host name string, such as xmachine
        • Numeric IP address, such as 127.1.255.3

        The host can be the same computer on which the product is installed or a different computer.

     2. Specify the administrative user name for the host.

     3. Specify the password or private key file for the administrative user so that the job manager can access and run jobs on the host. If the host does not require a password, you can specify a null String value of "".

     4. Specify other parameters as needed.

        Select Save security information and you will not need to enter the user name and password for every job manager action on the host.

     5. Click OK.

• Use the wsadmin registerHost command to register hosts. The command is in the JobManagerNode command group.

  1. Open a command window on the bin directory of the job manager profile.
  2. Run the wsadmin command to start wsadmin.sh and, optionally, use the Jython language.

     wsadmin -lang jython
     

  3. Run the registerHost command to make the host computer a target of the job manager.

     AdminTask.registerHost('[-host host_computer -hostProps [ [osType operating_system][username administrative_user]
      [privateKeyFile key_file_path] [passphrase passphrase][saveSecurity true] ]')
     

     host is the computer name of the host to register with the job manager. We must specify a host value.

     hostProps specifies properties of the host.

     registerHost -hostProps defined properties. We can specify one or more defined properties for the registerHost command, or specify undefined properties for the command.

     Property name	Property description
     osType	The operating system type. Specify osType to enable the command to complete faster. This optional property determines the means for connecting with the host. Valid values are: (AIX) aix hpux linux (Solaris) solaris (Windows) windows
     username	A user with authority to log in to the host. This property is required.
     password	The password for the given username. A value for password or privateKeyFile must be specified. If the host does not require a password, you can specify a null String value of "".
     privateKeyFile	The path to the private keyfile. If you do not specify a value for password, then specify a value for privateKeyFile.
     passphrase	A passphrase for the privateKeyFile, if needed.
     saveSecurity	Whether to store security properties (username, password, privateKeyFile, passphrase) with the host and used as default values for job submissions. If this property is given a value of true, then the security properties are stored with the host and used for subsequent job submissions to this host.

     Alternatively, you can run the registerHost command in interactive mode:

     AdminTask.registerHost('-interactive')
     

Results

After the host is registered with the job manager, the console or wsadmin displays the unique ID (UUID) of the host.

What to do next

Verify that the host is registered with the job manager and that the job manager can list the target resources.
