Product(s): Resiliency Platform (10.3)

Managing applications for remote recovery (DR)

This topic explains how to configure a resiliency group of InfoScale or non-InfoScale applications for basic monitoring.

To provide disaster recovery protection, you organize applications into a resiliency group and apply the remote recovery service objective. The wizard prompts for the inputs that are needed for the selected service objective and for the replication technology. The wizard then implements the configuration that is required for DR operations.

Resiliency Platform supports Oracle Data Guard as a replication technology. You can create resiliency groups with Oracle databases by applying the basic monitoring service objective. If the database is replicated using Oracle Data Guard, you can apply the remote recovery service objective. The Oracle Database replicated by Data Guard can be managed by Resiliency Platform only from a discovery host which has Oracle Net pre-installed and configured. You don't have to configure the Oracle database instance hosts directly into Resiliency Platform. The Per Front-End Terabyte license is consumed when a resiliency group is created for the Oracle database which is replicated by Oracle Data Guard.

To add a discovery host as a Application Host See Adding application hosts .

Once a discovery host is configured in Resiliency Platform, the Resiliency Platform discovers the Oracle databases that are configured in the tnsnames.ora file in ORACLE_HOME of the "oracle" user on the discovery host. These databases will then show up in the Applications page of the discovery host configuration marked with "Pending Inputs" icon. You can select the application and provide the requested inputs such as username/password of the database user. Provide the credentials of a user with SYSDBA or SYSOPER privileges. Once the credentials are validated, the Resiliency Platform performs deep discovery of the database and the database is available to be managed by Resiliency Platform in the Unmanaged Applications list and you should be able to create a resiliency group for the application.

To manage applications for remote recovery (DR)

Prerequisites
Ensure that you have completed the configuration prerequisites before you manage the application for remote recovery.
See Prerequisites for configuring applications for disaster recovery.
See Prerequisites for configuring InfoScale applications for disaster recovery.
See Prerequisites for creating a remote recovery resiliency group for Oracle database replicated by Data Guard.
Navigate
Assets (navigation pane) > Resiliency Group(s) tab > Manage & Monitor Assets
You can also launch the wizard from the Unmanaged or Overview tabs.
Select the applications:
On the Select Assets page, use one or more drop-downs to filter your list of applications.
Drag and drop applications to Selected Instances.
The next page displays the environment for the selected assets.
The next page lists the service objectives that are available for the selected applications. You can expand the service objectives to view details. Select the service objective that lets you perform the remote recovery of the applications.
Select the target (recovery) data center and then select the target data center application for each source data center application. Click Next.
On the Customize Network page, you can do the following:
- Choose Apply production - DNS customization to customize the DNS setting while performing the migrate or recover operations.
- Choose Apply Rehearsal - DNS customization to customize the DNS setting while performing the rehearsal operation.
- Choose to create pointer (PTR) records for the host. A PTR record resolves the IP address to the host name. It is used for reverse DNS lookups.
- Specify whether you want to abort the DR operation if the DNS updates fail.
- For each application specific source IP, select a target IP from the drop down by double clicking on the Target IP box.
  Note:
  If you are creating a resiliency group for Oracle Database replicated by Data Guard, you may also add additional rows for DNS customization of IP addresses and host names that Resiliency Platform was not able to discovery from the discovery host.
- Enter DNS registered host name for the application IP by double clicking on the DNS host name box.
- Remove the IPs rows for which you do not intend to set DNS customization.
When you complete your selections, click Next
Verify the summarized information and enter a name for the resiliency group.

When you finish the wizard steps, Resiliency Platform invokes a workflow which initializes the applications for DR configuration. You can view the progress or ensure that this operation is successfully completed on the Activities page.

See Viewing activities.

Verify that the new resiliency group is added to the Resiliency Groups tab.

See Viewing resiliency group details.
