• Release Date: January 22, 2025

This enhancement provides the ability to create and manage multiple local and remote standby databases linked to a primary database, providing flexibility for both data protection and disaster recovery. Local standby databases help minimize data loss, while remote standby databases safeguard against regional failures. This enhancement allows creation of up to 6 standby databases for a primary database.

In a typical Data Guard configuration, two standby databases are commonly used:

• Local Standby: A standby database in the same region as the production database is ideal for failover scenarios, offering zero data loss for local failures (such as database, cluster, or availability domain failures). Application failover impact is reduced in this case, as applications continue operating without the performance overhead of communicating with a remote region.
• Remote (Cross-Region) Standby: A remote standby database, located in a different region, is typically used for disaster recovery or to offload read-only query processing. A remote standby database setup ensures data protection against regional failures.

Some enterprise customers aim for symmetry after a site switch. For example, they may prefer to have both the primary and local standby in Region 1, and a remote standby with its own local standby in Region 2. In this configuration, there will be three standby databases. After a site switch, you will still have a primary database and a local standby readily available in the new primary region.

Additionally, customers can enhance their configurations by adding another standby database for testing purposes, leveraging our snapshot (read/write) standby capabilities.

In Oracle Data Guard configurations, it's common to have primary and standby databases in a synchronized state, including the same Release Updates (RUs) applied to both database homes. However, there are scenarios where you might need to allow different RUs between the primary and standby database homes, particularly during the patching cycle or for testing purposes.

Create Data Guard Associations:

• The primary and standby Oracle Homes must be of the same major database version.
• If the primary and standby Oracle Homes are running different RUs, a Data Guard association can be created only if the standby is on the same or higher RU than the primary database.
• The home for the standby can be a custom DSI or an Oracle image regardless of whether the primary is running on a custom DSI or Oracle image.

Switchover or Failover Database: The primary and standby Oracle Homes can be of any major database version or running different RUs.

Upgrade Database: The primary and standby Oracle Homes can of different major database versions.

Patch Database: If the primary and standby Oracle Homes are running different RUs, the standby can be patched to a higher RU than the primary database.

You can create and delete serial console connections to your ExaDB-C@C systems to diagnose and resolve VM guest operating system issues using an SSH connection in case standard SSH access to the VMs is not possible.

Requirements: The use of the serial console feature requires Exadata Infrastructure version 22.1.10 or higher for 22.X users and version 23.1.1 or higher for 23.X users. The serial console feature will be available on any new VM Clusters created immediately but will only be available on previously existing VM Clusters after the next quarterly maintenance cycle. Also, make sure to review all prerequisites stated below, including setting a password for either the opc or the root user. Failure to make necessary changes for meeting these requirements in advance will result in the inability to urgently connect to the serial console when the need arises when the VM is not otherwise accessible.

These must be allowed at your firewall in order for serial console connections to function. See Network Requirements for Oracle Exadata Database Service on Cloud@Customer Table 3-2 for further details.

• Release Date: May 23, 2023

Oracle Exadata Database Service on Cloud@Customer physical networks (client and backup) are configured to use active-backup by default. This mode is recommended for most customers. However, support for LACP (802.3ad active/active bonding mode) has now been added also for those customers who require it.

You can configure client and backup networks with LACP while provisioning the Exadata Infrastructure. The network bonding mode is set at the infrastructure level and will apply globally to all VM Cluster Networks, future or existing. Since the setting gets applied to each network interface individually, you have the flexibility to configure client and backup network interfaces independently from one another. For example, you can configure the backup network to LACP and the client network to Active-Backup, if desired.

On an existing Exadata Infrastructure that is now in use, you may change the network bonding mode from Active-Backup to LACP (or vice versa). However, note that this is a non-rolling update process and bonding modes are changed simultaneously on all Database Servers. You are required to manage your own switch settings on your network accordingly. You may experience a network outage and should plan for application downtime until your switch settings and ExaDB-C@C settings are made to match.

The use of LACP requires both the server and the switch(es) have compatible settings to allow LACP to work properly. To use LACP for ExaDB-C@C, you must configure your network switches such that they are compatible with the following parameter from the Linux ifcfg-bondethx configuration file:

BONDING_OPTS="mode=802.3ad miimon=100 downdelay=200 updelay=200 lacp_rate=1 xmit_hash_policy=layer3+4"

Note that the BONDING_OPTS line in the host operating system cannot be changed, so customer switch settings must be compatible with the parameters stated above without alteration.

If you have provisioned DB Homes with a Database Software Image (DSI), then enabling Data Guard operations will default to the same DSI as the primary DB Home.

With this enhancement.

• You can change the automatically selected primary DSI to a different DSI for the standby database.
• If the DSI used to create the primary database is not available, then enabling Data Guard will use the latest Oracle-published image. Optionally, you can configure the standby database to have a DSI of your choice.

In both cases, the system will warn you of potential issues with having different images for the primary and standby databases.

For certain deployments, you may want to expand beyond the maximum number of compute and storage servers supported within a single Exadata Infrastructure rack. With this enhancement to compute and storage expansion, you can now have additional compute and storage spanning multiple racks available for VM Clusters provisioned on the Exadata Infrastructure.

Base systems are not eligible for multirack expansion. Multi-rack applies only to the following shapes:

• X8M-2 standard shapes
• X9M-2 standard shapes

Note: Exadata Infrastructure with more than 8 compute or 12 storage servers requires a multi-rack deployment.

The "multi-rack" selection will drive the maximum number of compute and storage servers you can specify in the server configuration.

• Single Rack:
  • All Systems: 8 compute and 12 storage
• Mulit-rack:
  • X7, X8, and all Base Systems: Not Applicable
  • X8M and X9M Sytems: 32 compute and 64 storage servers

Pre-deployment process:

• If multi-rack is required or desired, the FE will provide the customer with a JSON configuration file.
• The customer uploads the config file when creating or expanding the Exadata Infrastructure.

Deployment process:

• When the customer creates the infrastructure and selects multi-rack, they must upload the JSON so the control plane can correctly generate the config bundle for download. The JSON file will be used to properly configure the additional components. Uploading the JSON will only be mandatory for deployments identified as multi-rack.
• If a customer fails to identify an infrastructure as multi-rack and subsequently they determine it is multi-rack, they will have to delete that infrastructure and recreate it.
• If a customer expands an existing infrastructure and remains within a single rack (only adding servers), then there is no change to the current deployment process.
• When a customer expands an existing infrastructure and adds a new rack, or expands an infrastructure with an existing expansion rack, they will need to choose the multi-rack deployment type and upload a new Multi-Rack Configuration File (JSON).

Elastic Compute Expansion enables the addition of an arbitrary number of DB Servers to Exadata Cloud@Customer infrastructure. In conjunction with the previously released Elastic Storage Expansion feature, new infrastructure installations can now be better customized by provisioning a discrete number of DB Servers and Storage Servers. Also, compute capacity for the existing infrastructure deployments can now be expanded by adding individual DB Servers in a manner similar to Elastic Storage Expansion.

In addition, significant changes have been made to the VM Cluster Network object to facilitate the ability to subset network resources to certain DB Servers.

Follow the links below for instructions on how to provision infrastructure and activate. Once the DB Servers are activated, they are recognized and available for use immediately, but the additional resources need to be added to your VM Clusters. This is not done automatically.
