## Creating a Management Domain

The command `hadbm createdomain` creates a management domain containing the specified HADB hosts. The command initializes internal communication channels between hosts and the persistence configuration store.

The syntax of the command is:

    hadbm createdomain
     [--adminpassword=password |--adminpasswordfile=
    file | --no-adminauthentication] [--agent=maurl]
     hostlist

The hostlist operand is a comma-separated list of HADB hosts, each of which is a valid IPv4 network address. Include all the hosts that you want to be in the new domain in the hostlist.

See General Options for a description of the command options.

Before using this command, be sure an HADB management agent is running on every host in the hostlist. Additionally, the management agents must:

- Not be members of an existing domain.

- Be configured to use the same port.

- Be able to reach each other over UDP, TCP, and with IP multicast.

After `hadbm` creates the management domain, it enables all the hosts in the domain. Then the management agents are ready to manage databases. After creating HADB domains, the next step is to create the HADB database. For more information on creating HADB databases, see Creating a Database .

##### Example 3–2 Creating an HADB Management Domain

The following example creates a management domain on the four specified hosts:

`hadbm createdomain` `--adminpassword=` password `host1,host2,host3,host4`

After `hadbm` successfully executes the command, you will see the message:

    Domain host1,host2,host3, host4 created.

After creating HADB domains, register the path and version of the HADB packages with the management agents.
