The Oracle solution playbook “Implement Mid-tier Replication in an OCI Disaster Recovery Architecture” provides an analysis of the different file system replication approaches used by middleware tiers in active-passive Disaster Recovery configurations. It describes how to synchronize middle-tier file systems across regions in OCI to ensure consistency and minimize downtime during failover or switchover events.
Highlights:
- This Oracle solution playbook provides an overview of mid-tier file system replication throughout the lifecycle of a disaster protection system.
- The strategies described in this playbook apply to different middleware system types configured with an active-passive disaster recovery topology on Oracle Cloud Infrastructure (OCI). This includes disaster recovery setups for middle-tier systems that have been created manually, systems created with the WLS_HYDR framework, or systems using OCI Marketplace stacks.
- It presents the main native replication technologies available in OCI for middle tiers: OCI Block Volumes replica and the OCI File Storage replica (as storage-level replica technologies), and also alternatives like rsync (as an operating system tool) and Database File System (DBFS).
- It provides real-world implementations of the middleware Disaster Protection systems using these technologies.
- It offers different strategies and sample scripts (through Oracle MAA’s GitHub repo) to automate the replication processes, reducing operational overhead and minimizing the risk of errors.
- It discusses methods to handle site-specific configuration, to ensure that both primary and standby systems operate correctly within their respective environments.
- It provides a comprehensive comparison of the main features of each mid-tier replication approach by evaluating key aspects such as management and setup complexity, Recovery Time Objective (RTO), and Recovery Point Objective (RPO).
- The solutions provided in the book enhance the system’s resilience, ensure business continuity, and implement Oracle Maximum Availability Architecture best practices for disaster protection.
- By following the strategies outlined in this document, organizations can select and implement the most effective mid-tier replication approach for their needs.
Intended Audience:
This document is particularly beneficial for mid-tier administrators, system architects, and IT professionals responsible for designing, implementing, and managing disaster recovery solutions for middleware applications on OCI. Organizations looking to improve the reliability and resiliency of their mid-tier systems will find this guidance extremely helpful.
