Reference Architectures – Level Set

• Developed and validated by Oracle

• Capabilities carry forward as you progress from one architecture to the next

• Achieving stated service levels requires:

– Utilization of prescribed HA capabilities

– Utilization of prescribed configuration and operational best practices

– Due diligence during pre-production testing

Summary • Single instance database with auto-restart

• Restore from backup to resume service following unrecoverable outages

Requirements • All that is required for Bronze is a separate location to store backup data. This

may be as simple as a network file share, a tape library, or an offsite backup.

• Local and remote backup copies are recommended for fastest recovery and

protection against site failures

Active database instance used for HA

• Active-Active cluster provides best HA for machine and database instance outages and hardware/software maintenance and patching

Replicated copy of database used for HA

• Best HA and protection against data corruptions, database and availability domain outages, and database upgrades

Summary:

Oracle RAC

Bronze +

• Active-active RAC cluster - HA for machine or database instance outages

• Auto service failover to second machine, zero downtime required for restart

• Zero downtime rolling maintenance across database instances

• All database instances open read-write to scale workload

• RAC One-Node is an option for active-passive HA if scalability is not required

Requirements • This tier adds to infrastructure requirements to support Oracle RAC: inter-node

communication, shared storage and multi-node compute

Silver: Replication

Silver

Summary:

Data Guard

Bronze +

• Database replication (Data Guard) synchronizes a local HA copy in a separate

availability domain for maximum fault isolation: Independent data validation,

corruption protection, separate power, cooling, network, server, and storage.

• Automatic database failover and automatic application failover to the HA copy

• Zero data loss using synchronous replication

Requirements • This alternative adds a duplicated and separate environment to support the

synchronized copy used for HA.

• Additional configuration required for automatic database failover

Summary

Silver +

• Remote database replication using Active Data Guard eliminates S.P.O.F. for

HA from data corruptions, cluster and site outages

• Fast database failover (manual or automatic) - no downtime required for restart

• Low-downtime database rolling upgrades

• Read-only workloads are offloaded to the remote copy – all systems active

Requirements • The remote copy is completely isolated from outages impacting the primary

system: independent Oracle data validation, separate power, cooling, network,

server, storage, building, geography, etc. Remote system may have less

capacity during normal runtime and scale up to multi-instance after failover.

Summary

Gold +

• Data Guard replication synchronizes local (HA) and remote (DR) copies

• HA copy is deployed in a separate availability domain for maximum isolation

• Application tier in primary datacenter automatically fails over to the local HA

copy of the production database following unplanned cluster outage or

database rolling maintenance.

• Oracle GoldenGate and Edition-Based Redefinition for zero downtime upgrades

Requirements • Three complete, duplicated, separate infrastructures are required. Local HA

copy is all but geographically isolated from primary. DR copy is geographically

isolated. Advanced capabilities make local outages and all maintenance

transparent to applications. Only site outages require failover to remote copy.
