Create a Database Zone Domain

The ability to create and configure a Database Zone Domain is available starting with SuperCluster version 2.4.

Creating a Database Zone Domain reserves the specified amount of resources for the domain. The domain is not installed and available until you deploy it. See Deploy an I/O Domain.

You can use a recipe to assign the amount of resources to the Database Zone Domain and configure the network parameters, or you can define the resources and network parameters on the fly. If you plan to use a recipe, it must exist before you perform this procedure. See Choose an I/O Domain Creation Method.

You can use a network recipe to assign the network resources to the domain, or you can define the resources on the fly. If you plan to use a recipe, it must exist before you perform this procedure. See Choose an I/O Domain Creation Method. If you plan to assign VLAN tags to the domain, they must exist in Network Resources before you perform this procedure. See Add VLAN Tags (Administrators).

The assistant does not allow you to assign more resources than are available.


Note -  (Only applies to SuperCluster version 2.6 or earlier) If you plan to change CPU and memory allocations for dedicated domains with the osc-setcoremem tool, do so before you configure any domains. Refer to the Administration Guide for your SuperCluster model (for example, Configuring CPU and Memory Resources (osc-setcoremem) in Oracle SuperCluster M8 and SuperCluster M7 Administration Guide).

This note does not apply to SuperCluster 3.0 (or later).


  1. Access the SuperCluster Virtual Assistant.

    See Log In to the SuperCluster Virtual Assistant.

  2. In the navigation panel, select I/O Domains.
  3. Click Add.
  4. Define these parameters.
    image:A screen shot showing the initial I/O Domain Add menu with Database Zone Domain selected.
    • Domain Type – Choose Oracle Database Zone Domain.

    • Resource Recipe – Choose one of these options:

    • Network Recipe – Choose one of these options:

  5. If you selected Custom Resource Recipe for resources, define these resources and click Next:
    • Number of Cores – Choose a minimum of two cores for a Database Zone Domain.

    • Memory – Choose a minimum of 32 GB Memory for a Database Zone Domain.

    • Number of 10GbE Interfaces – Choose up to two 10GbE Interfaces for a Database Zone Domain.

    • Number of FC ports – Choose up to two assignable fibre channel ports for a Database Zone Domain.

  6. If you selected Custom Network Recipe for the network, define these resources and click Next.
    • Domain Name – Type the domain name, such as example.com, for this Database Zone Domain.

    • Name Servers – Type a list of comma or space-separated IP addresses of name servers for this Database Zone Domain.

    • Time Servers – Type a list of comma or space-separated IP addresses of time servers for this Database Zone Domain.

    • Time Zone – Choose a time zone for this Database Zone Domain.


    Note -  When you select Database Zone Domain as the domain type, the RAC ID field is not available. You will assign RAC IDs to the zones within the Database Zone Domain, not to the Database Zone Domain itself.
  7. Review the resources and click Next.

    Note -  If you requested more resources than are available, the assistant highlights the resource on each physical host that does not meet requirements.
  8. Choose the physical host and add network information.
    • If you are creating a Database Zone Domain with a Custom Resource Recipe and a Custom Network Recipe, configure these parameters. Depending on your choices, you may see fewer fields.

      • Maximum Number of Zones – (as of SuperCluster 3.0) From the drop-down list, choose the maximum number of zones that can be created in this I/O Domain. The maximum number that you are able to select is two times the number of cores that are allocated to the I/O Domain.

      • Physical Host – Choose the compute node where the Database Zone Domain will reside.

      • Install Group – Depending how the assistant is configured, the Install Groups might be automatically assigned or you might be able to choose a different Install Group.

      • Management Network – You can select the Management Network from which to assign an IP Address. All Management Networks defined in the Added Network Resources table of the Network Resources page with sufficient free IP Addresses can be selected. If the Resource Recipe for the I/O Domain that you are configuring contains two Management Interfaces, you will see two sets of inputs in order to provide two entries for the Management Network, IP Address, VLAN Tag, and Hostname. In this case, two Management interfaces will be configured in the I/O Domain after it has been deployed. If the I/O Domain has two Management Interfaces, then each of those Management Interfaces can use any Management Network with sufficient available IP Addresses.

      • Management IP Address – If administrative privileges were set, you can select the management or client IP addresses directly.

      • Management Hostname – Type a unique name for this Database Zone Domain.

      • Network Endpoint – This option is only displayed when port pairs are configured (see Configure Port-Paired Networks (Administrators)).

        If port pairs are configured, select the network endpoint that you want the I/O Domain to use.

      • Client (10Gb) Network – You can select the Client Network from which to assign an IP Address. All Client Networks defined in the Added Network Resources table of the Network Resources page with sufficient free IP Addresses can be selected. If the Resource Recipe for the I/O Domain that you are configuring contains two Client (10Gb) Interfaces, you will see two sets of inputs in order to provide two entries for the Client Network, IP Address, VLAN Tag, and Hostname. In this case, two Client (10Gb) interfaces will be configured in the I/O Domain after it has been deployed. If an I/O Domain has two Client Interfaces, then each of those Client Interfaces can use any Client Network with sufficient available IP Addresses.

      • Client (10Gb) IP Address – Displayed only if the IP Address assignment is set to manual. See Configure How IP Addresses are Assigned (Administrators). When this setting is enabled, you see a drop-down list of IP Addresses from the selected Client (10Gb) Network and you can select the desired IP Address.

      • Client (10Gb) Primary VLAN Tag – If VLAN tags were added to the Network Resources (see Add VLAN Tags (Administrators)) you can select a VLAN tag from the drop-down list to assign to this I/O Domain. This field is always displayed on the I/O Domain configuration page, even if you did not define any VLAN tags in the Network Resources section. The default is no VLAN tag, which is indicated by ---. VLAN tags are only configured on the 10 GbE client network. Primary VLAN tags are applied to the network interface and to the VF.

      • Client (10Gb) Aux VLAN Tag – As of SuperCluster version 3.0, if VLAN tags were added to the Network Resources (see Add VLAN Tags (Administrators)) you can select one or more VLAN tags from the auxiliary list, otherwise the list is empty. auxiliary VLAN tags only apply to VFs. A typical use of auxiliary VLAN tags is to assign them to zones that are later created in the I/O Domain.

      • Client (10Gb) Hostname – Use the default, or type a unique name for the Client Hostname for this Database Zone Domain.

      • Storage IB Network – Choose an available network subnet.

      • Storage IB Hostname – Use the default, or type a unique name for the ZFS Storage Hostname for this Database Zone Domain.

      • Exadata IB Network – Choose an available network subnet.

      • Exadata IB Hostname – Use the default, or type a unique name for the first Exadata IB Network for this Database Zone Domain.

    For example:

  9. Click Allocate to create the Database Zone Domain.

    The SuperCluster Virtual Assistant reserves the system resources but does not deploy the configuration. You can deploy the Database Zone Domain at your convenience. See Deploy an I/O Domain.


    Note -  Resources are reserved for 120 hours (five days). If the domain is not deployed within that time frame, the resources are returned to the free pool.

    If the assistant detects a configuration issue, a message appears:

    • Insufficient resources. For example:

      Insufficient Unallocated Cores available on the chosen Compute Node. 10 Requested, 
      8 Remaining.
      
    • Configurations that might have performance issues. For example:

      Error: VF allocation requires dedicated core in the same locality group for
      performance reasons.
      requested core count: 1  optimal core count based on number of requested VFs: 2
      

    If you receive one of these messages, click Cancel and configure a new domain using a recipe that requests fewer or different resources.

  10. Verify that the Database Zone Domain allocation completed.

    A confirmation panel is displayed at the top of the I/O Domains screen. The State column displays the status of the allocation.

  11. Add the management and client networks to DNS.

    The network host names and IP addresses are displayed in the confirmation panel in the I/O Domains screen, and are available when you view the Database Zone Domain's details.

  12. Consider your next action.
