Create a Replication Scenario

Protecting UNIX and Linux machines using Arcserve RHA requires scenarios that identify the Master and Replica servers, as well as properties that control scenario behavior. You can create File Server or Oracle scenarios, as needed. Auto-discovery is used to protect only one Oracle instance in one scenario. If you want to protect more than one Oracle instance in one scenario, use the File Server scenario type. Scenario creation is a wizard-based process and the steps for creating File Server and Oracle scenarios are quite similar. Where differences exist, they are clearly noted. For more detailed instructions, see the appropriate Operation Guide.

Note: Root directories cannot be intersected in different scenarios; that is, you cannot create a second Replication scenario using the same master directory and root directory used for your first Replication scenario.

Note: RHA cannot protect the block device mounted to the RHA root directory after you run the scenario.

Use your web browser to connect to Arcserve RHA using the Control Service, log onto the portal page and then run the Management GUI. If this is the first time you have run the GUI, it is installed automatically using ClickOnce™ technology. The following is the URL of the portal page:

1. Select Scenario, New from the Manager, or click the New Scenario button on the toolbar.

   The New Scenario Wizard opens.

2. Select Create New Scenario, and click Next.

   The Select Server and Product Type dialog opens.

3. Select the required scenario options, as follows:
   1. From the Select Server Type list, select the type of scenario you want to create. For UNIX/Linux replication, only File Server and Oracle scenarios are supported.
   2. From the Select Product Type options, select Replication and Data Recovery Scenario (DR).
4. Click Next.

   The Master and Replica Hosts dialog opens.

5. Enter the names or IPs of the Master and Replica servers you want to protect, and click Next.

   The Engine Verification dialog opens. Wait while the Engine version status is verified. If the current version is outdated, Arcserve RHA asks if you want to update it now. You can install the latest version or continue. When verification is complete, click Next.

   Note: If the scenario type is Oracle, you are prompted for user credentials. You should enter credentials for an account with administrative privileges in the database so that Arcserve RHA can query the Oracle configuration on the Master server.

6. Enter the Oracle instance name, Oracle DBA and user name/password and click OK.
   • In File Server scenarios, the Master Root Directories dialog opens. Select the files, directories, or both to replicate from the Master and click Next to continue to the Replica Root Directories screen.
   • In Oracle scenarios, the Tablespaces for Replication dialog opens in place of the Master Root Directories dialog. Arcserve RHA provides a list of results auto-discovered on the Master server. Select or clear databases for replication as needed and enable the option Replicate new user-created files in listed root directories. Click Next to continue to the Replica Root Directories screen.

   The Replica Root Directories dialog opens. Depending on the type of scenario you are creating, the Replica Root Directories dialog shows a list of directories for the Oracle database or File Server.

7. Select the files, directories, or both on the Replica in which the data that you want to replicate will be stored, and click Next.

   Note: If the same directory structure exists on the Replica server, the wizard automatically selects it as the directory to which to replicate.

   The Scenario Properties dialog opens.

8. Configure the Master and Replica properties. Typically, the default values are sufficient. You can modify all the settings in this pane after the scenario is created.

   Note: The spool is a folder on the disk where data to be replicated is temporarily stored (that is, spooled). The spool parameters, located in the Properties tab on both the Master and Replica, or set with the New Scenario Wizard, determine how much disk space is available for the spool. In most cases the default values are sufficient. However, if you choose to change this value, it should be at least 10% of the total dataset size. See the Arcserve RHA Administration Guide for more information.

   The Master and Replica Properties dialog opens.

9. Set the Data Rewind option to On on the Replica Properties pane if you want to enable recovery of lost data from the Replica using rewind points. For more information about using Data Rewind, see the topic Data Rewind.
10. Click Next when you are satisfied with the Master and Replica properties.

    The Scenario Verification dialog opens and the wizard verifies the scenario configuration.

11. Click Next if the scenario is verified successfully, otherwise if errors appear click the Back button and correct the scenario settings.

    After the scenario is verified, the Scenario Run page opens where you are prompted to run the scenario. Running the scenario starts the data synchronization process.

12. Click Run Now to run the scenario, or click Finish to finish scenario creation and run the scenario later.

    The synchronization process starts.

For non-global zones on Solaris

Create multiple scenarios in the global zone and then manage all scenarios from there. Most steps are same except the following steps:

1. Enter the global zone IP address as the master IP address.
2. Use the following commands to get the zone and zone root directory information:

   /usr/sbin/zoneadm list -vi
   

   zonecfg -z <zonename> info
   

3. While setting the root directory, manually add the non-global zone root directory to the path that you want to protect. In this case, you cannot use auto discovery for the applications such as Oracle.
