Dataguard between two Exadata Cloud at Customer

Facundo Ezequiel Grande

Hello,

Is it possible to create a DataGuard between 2 "Exadata Cloud at Customer" of different sites?.

Thanks.

If you are asking if we can create dataguard between 2 exadata cloud servers.

The answer is Yes.Important thing will be network bandwidth between those sites.

Oracle Data Guard configuration on Exadata Cloud Service, the standby database is a physical standby database. A physical standby database provides a physically identical copy of the primary database, with on-disk database structures that are identical to the primary database on a block-for-block basis. A physical standby database is kept synchronized with the primary database, through Redo Apply, which recovers the redo data received from the primary database and applies the redo to the physical standby database.

Hi Sunny, thanks for your answer.

I have this scenario:

• Primary Site: Exadata Cloud at Customer (OCI-C) with one Control Plane and one Exadata.
• Secondary Site: Exadata Cloud at Customer (OCI-C) with one Control Plane and one Exadata.

So I can´t create a database with DataGuard using the Control Plane's dashboard because we have 2 differents Control Planes, one per site. I don´t know if exists any Oracle Note that explains the procedure to create a DataGuard with this scenario.

Thanks.

It would be better if you ask this question with Support team.Better raise

a ticket in metalink or with your Oracle sales representative.

Hello User_KC98K,

On Exadata Cloud at Customer (OCI-Classic) [GEN 1] doesn´t exist the compartment concept.

Your documentation is about Exadata Cloud at Customer (OCI) [GEN 2].

For gen1

Before you create a database deployment that uses an Oracle Data Guard configuration, you must ensure that both the primary and the standby sites are configured to enable the network communication that is required for Oracle Data Guard.

In summary, network traffic must be able to flow:

• Between both sites (primary and standby).
• In both directions (inbound and outbound at each site).
• On both the administration network (if available) and the client network, and across all combinations (client-to-client, administration-to-administration, client-to-administration, and administration-to-client).
• On both the SSH port (22) and the Oracle Net Services port (1521).

Hello User_KC98K,

Yes, I ensure that both the primary and the standby sites are configured to enable the network communication that is required for Oracle Data Guard.
