Diagnose and resolve replica lag in Amazon RDS for Oracle replicas – Part 2

This post is the second in a two-part series on reducing replication lag for Amazon RDS for Oracle Read Replicas. In Part 1, we discussed redo compression and configuration options to optimize replica lag. In this post, we show you how to monitor replica lag using Amazon CloudWatch metrics and database views, identify common root causes through wait event analysis, and how to troubleshoot and resolve performance issues.

Well-Architected design for resiliency with Oracle Database@AWS

Oracle Database@AWS delivers enterprise-grade database capabilities through database services that use Oracle Exadata infrastructure managed by Oracle Cloud Infrastructure (OCI) within Amazon Web Services (AWS) data centers. High availability (HA) and disaster recovery (DR) options are important aspects to consider when migrating or deploying your critical database in Oracle Database@AWS to help make sure the architecture can meet the service level agreement (SLA) of the application. This post will help you implement and maintain Data Guard configurations that follow Oracle’s Maximum Availability Architecture (MAA) best practices and the AWS Well-Architected Framework. We will show how to select the right network architecture and configure Data Guard associations for both cross-AZ and cross-Region deployments, making sure your applications maintain seamless connectivity during role transitions.

High availability for Oracle GoldenGate Microservices Architecture in AWS

GoldenGate supports Classic and Microservices Architectures. In Part 1 of this series, we covered high availability for GoldenGate classic architecture in AWS. In this post, we discuss a reference architecture for GoldenGate Microservices Architecture (MA) in AWS. The GoldenGate Hub is a widely used deployment model that simplifies operations and lessens the use of system resources on both the source and target systems. This is in contrast to the conventional method where GoldenGate components run directly on the source and target systems.
