We provide consulting, training maintenance and outsourcing services in Oracle database disaster recovery solutio (DR) Data Guard, high availability solution Real application Cluster and maximum availability architecture which consists of both dataguard and real application cluster.
Oracle Data Guard
Actually Data Guard is a disaster recovery solution that can be located at the same or different locations. It ensures high availability, data protection as well. In this structure, you can have 1 primary and up to 30 standby database servers. If you have active data guard license you can open standby database read only mode.
In case of disaster you can activate your passive database and continue to work within 5-10 minutes without job loss.
You can only use it if you have enterprise license otherwise we need use 3rd party solutions such as DBvisit solutions.
Oracle Real Application Cluster
All nodes are active in Oracle’s cluster solution. Applications or users can connect to any of them. Which servers the users will connect to can be determined by the services. If there is a problem with the connected nod, they can continue to work by connecting to one of the other nods without job loss. We recommend that for critical businesses.
Oracle Max. Availability Architecture
In this Maximum Availability Architecture, the above mentioned RAC and Data Guard are used together. We recommend for very critical businesses.
Oracle Database High Availability and Disaster Recovery Solutions: Data Guard and Real Application Clusters (RAC)
Database management systems are one of the cornerstones of modern business. Protection of critical data, continuous availability, and uninterrupted service delivery are essential elements of a successful business operation. Oracle offers advanced high availability (YE/HA) and disaster recovery (FKM/DR) solutions to meet these requirements. Among these solutions, Oracle Data Guard and Oracle Real Application Clusters (RAC) stand out. In addition, uninterrupted business continuity can be ensured with maximum high availability architectures (MAA/MYE) where these technologies are used together.
Oracle Data Guard: Secondary Solutions for Disaster Recovery and High Availability
Oracle Data Guard is a technology used to provide database disaster recovery and high availability. It includes two main components: primary and standby databases. The key functions of Data Guard are:
Database Backup and Replication: Data Guard instantly copies all data from the master database to the secondary databases. This keeps data loss to a minimum, ensuring continuous operation of the system.
Automatic Migration and Rollback: When a failure occurs in the master database, Data Guard automatically deploys the secondary database, ensuring uninterrupted service. After the failure, the system can return to its original state.
Load Balancing and Reporting: Data Guard can also be used to report backup databases and distribute query loads, thereby improving the performance of the master database.
Oracle Real Application Clusters (RAC): Parallel Compute for High Availability
Oracle RAC is a solution designed to provide high availability and scalability at the database level. The RAC is notable for its following features:
- Parallel Processing Capacity : RAC allows multiple servers (nodes) to access a single database at the same time. This helps with load balancing and increased compute capacity.
- High Availability: Even if a failure occurs in one or more servers, the other servers maintain access to the database, so the system operates without interruption.
- Dynamic Scalability: RAC allows for easy onboarding of new servers based on system requirements, so performance and capacity can be dynamically increased.
Maximum High Availability Architecture (MAA): Using Data Guard and RAC Together
Oracle uses a combination of Data Guard and RAC technologies to provide maximum high availability architectures (MAA). This integrated approach offers the following benefits:
- Multi-Layered Protection: Data Guard and RAC provide both high availability and disaster recovery at the database level. RAC increases processing power, while Data Guard provides the database’s redundancy and disaster recovery capabilities.
- Load Balancing and Uninterrupted Access: The combination of these two solutions enables both performance load balancing and uninterrupted access in case of failure.
- Business Continuity: It both prevents data loss and ensures that the system is up and running quickly against possible failures.
