DDS search facility

The DDS search facility is one of the search facilities supported by HCP. This facility works with Hitachi Data Discovery Suite to provide the search functionality available in the HCP Search Console.

DDS is a separate product from HCP. It runs on its own servers and has its own installation and configuration procedures.

NoteCurrently, DDS does not support the use of IPv6 networks for communication with HCP.

About the DDS search facility

The DDS search facility uses an index to find results for searches performed in the HCP Search Console. This index is based on object data and system metadata. For the Search Console to work with the DDS search facility, however, you first need to perform some configuration in both DDS and HCP.

DDS search facility index

The DDS search facility index resides in DDS. DDS builds and maintains this index by reading the objects in the namespaces you make known to it.

For DDS to index objects in a namespace, all of these must be true:

  • The HTTP or HTTPS protocol must be enabled for the namespace.
  • The effective permission mask for the namespace must include the read and search permissions.
  • The HCP management API must be enabled both at the system level and for the tenant that owns the namespace.
  • HCP must be defined as a subdomain in your DNS.

DDS search facility configuration information

You use the DDS administrative interface to specify the information DDS needs in order to index and search HCP namespaces. You use the HCP System Management Console to specify the information HCP needs in order to use the DDS search facility with the HCP Search Console.

For information about using the DDS administrative interface, see the applicable DDS documentation.

NoteDepending on security requirements, the person specifying the HCP information in the DDS administrative interface may be someone other than you. For example, your site may have an DDS system administrator who is responsible for this, or you may choose to make the DDS administrative interface available to HCP tenant-level administrators.
Namespace mappings

To make a namespace known to DDS, you use the DDS administrative interface to map the namespace to an DDS server. To do this, you need to know:

  • The name of the domain associated with the data access network for the tenant that owns the namespace. To enable DDS to communicate with HCP over this network, it must have IPv4 addresses assigned to it.
  • The namespace name.
  • The name of the tenant that owns the namespace.
  • For an HCP namespace, either of these:
    • The name and password of a tenant-level HCP user account with the monitor or administrator role
    • The name and password of a recognized Active Directory user for which an applicable system-level HCP group account has the monitor or administrator role
  • For the default namespace, either of these:
    • The name and password of a system-level HCP user account with the monitor or administrator role
    • The name and password of a recognized AD user account for which an applicable system-level HCP group account has the monitor or administrator role
  • For an HCP namespace, either of these:
    • The name and password of a tenant-level HCP user account whose data access permissions for the namespace include read and search
    • The name and password of a recognized AD user account for which an applicable tenant-level HCP group account has the read and search data access permissions for the target namespaces
  • The protocol that DDS needs to use to access the namespace (HTTP or HTTPS).
    NoteIf the password for either account changes, you need to update the namespace mapping in DDS.
User account mappings

To use the Search Console:

  • To search HCP namespaces, a user needs either of these:
    • A tenant-level HCP user account whose data access permissions for the target namespaces include read and search
    • A recognized AD user account for which an applicable tenant-level HCP group account has the read and search data access permissions for the target namespaces
  • To search the default namespace or to use a system-level user account to access and search HCP namespaces, a user needs either of these:
    • A system-level HCP user account with the search role
    • A recognized AD user account for which an applicable system-level HCP group account has the search role

In all of these cases, the HCP or AD user account must be mapped to an DDS user account.

You use the DDS administrative interface to map HCP and AD user accounts to DDS user accounts. To do this, you need to know the username and password of each HCP and AD account you want to map.

You can map one or more HCP and AD accounts to any given DDS account. For the simplest configuration, map all the HCP and AD accounts to a single DDS account. For the greatest security, map each HCP and AD account to a different DDS account.

Note

If the password for an HCP or AD user account changes, you need to update the account mapping in DDS.

When creating an account mapping, you need to specify the URL for the applicable tenant. For the default tenant, the tenant name in the URL must begin with an uppercase D.

HDDS server

To make the DDS search facility available to HCP, you need to tell HCP about the applicable DDS server. You do this in the HCP System Management Console.

Statistics account

HCP can report counts of indexed objects in the HCP System Management Console and Tenant Management Console. To enable HCP to report DDS search indexing statistics, you need to specify an DDS user account name and password in the DDS search facility configuration in HCP. The account that you identify must be in the Administrator group in DDS.

Configuring the DDS search facility

Before you begin

To view the Search page, you need the monitor or administrator role. To configure search, you need the administrator role.

Procedure

  1. On the left side of the Search Facility Settings section on the Search page, click HDDS.

  2. In the HDDS panel, in the HDDS Server IP Address field, type the host name or IP address of the DDS server.

  3. In the Port field, type 8443.

  4. To enable the display of indexing statistics, select Show statistics.

    The Username and Password fields appear.
  5. In the Username field, type the user name for an DDS user account in the Administrator group.

  6. In the Password field, type the password for the DDS user account.

    If you’re modifying the DDS search facility settings and you leave the Password field empty, the previously set password remains in effect.

  7. Optionally, click Test to verify that you have correctly specified the DDS server specification, port number, and user account information.

    TipYou can return to the Search page to test the DDS configuration at any time. If Show statistics is not selected, you need to temporarily select it and provide a valid user name and password for the test to work.
  8. To disable the display of indexing statistics, deselect Show statistics.

  9. Click Update HDDS Settings.
