Creating a Protected Group

Creating a Protected Group

eReplication provides policy-based automatic protection for different protected objects. To implement policy-based automatic protection, you must create protected groups for the protected objects on eReplication. Once the protected groups are created, they will be automatically executed based on the preset policies.

Creating a Protected Group for Oracle Databases

This section describes how to create a protected group at the production site for Oracle databases that need DR protection. The system automatically identifies suitable protection policies for the protected group when creating the protected group.

Prerequisites

  • At least one production site has been created.
  • Hosts or host groups and storage devices for host applications have been added to the production site.

Context

The protected objects belonging to one protected group reside on the same storage device. Each protected object occupies independent storage LUNs or volumes.

Procedure

  1. In the menu bar, Choose Protection.
  2. Click Create.
  3. Select the protected object.
    1. Set Production Site and Production Host(Group).
    2. In the Available Databases area, select a database to be protected.
    3. In the Verification dialog box that is displayed, enter necessary authentication information and click OK.

      Set Authentication Mode, which can be Database Authentication or OS Authentication.

      • Database Authentication: based on an Oracle database user name.

        Enter the sys user name and its password as the authentication information. If you use another user name for authentication, the database cannot be started when you recover or test it.

      • OS Authentication: based on an operating system user name.

        For a single-instance database or Oracle RAC cluster deployed on ASM disk groups, you need to enable OS Authentication for the DR database as required by Oracle officially. After data is recovered, select Database Authentication for security purposes.

    4. In the Archive Log Protection list of the Available Databases area, set whether to enable protection for archive logs.

      Archive logs record all operations on the databases. They are used to recover data of Oracle databases that are abnormally stopped, maximizing data security.

      When you enable the archive log mode but not enable Archive Log Protection for the production Oracle database, disable the archive log mode or configure an archive directory for the DR database. Otherwise, the DR database cannot be started when you perform DR operations.

  4. Click Next.
  5. On the Protection Policy page, the system automatically matches supported protection policies. Select a policy based on your data protection solution.

    When the mirroring (VIS) DR technology is used, select Mirror:High-availability(HA) DR solution.

    NOTE:
    • If there are suitable protection policies, you can select a protection policy based on your data protection solution and modify the time policy of the protection policy.
    • If there is no suitable protection policy, check whether the storage devices used by protected objects have been configured as planned. If the storage devices have not been configured, configure them as planned. After configuration, perform the following operations: On the menu bar, select Resources. Select a node under the management server. In the site node, click Storage, in the line where the storage device resides, click Refresh to refresh the storage device information under the site. Then, recreate the protected group.

  6. Click Next.
  7. Set Name and Description of the protected group.

    • Name: contains 4 to 32 characters, including letters, digits, underscores (_), and hyphens (-), but cannot start with a hyphen (-).
    • Description: contains 0 to 255 characters.

  8. Click Finish.
  9. Click OK.
Related Operations
  • If the protected objects of a protected group or their used storage devices change. On the menu bar, select Resources. And refresh resources or storage devices where the protected objects reside. Then go to the protected group page and refresh protected objects of the protected group by clicking More > Refresh. After the command for refreshing information is sent, you can view details about the command execution in Background Task.
    NOTE:

    If a recovery plan has been created for a protected group, you can refresh protected objects only when the recovery plan status is Ready, Clear completed, Rollback completed, or Reprotection completed.

  • To ensure that information about protected groups is refreshed successfully, you must refresh information about storage devices and hosts at both the production site and DR site.
