Introduction Oracle Application Continuity hides database interruptions from end-users and applications. A simple test using SQL*Plus was discussed in this blog post. However, SQL*Plus is usually not your real application that will be used in production. Also, SQL*Plus is not a pooled application, and it’s recommended to use Connection Pools for Application Continuity. This blog…

Introduction Enabling Oracle Data Guard in Oracle Cloud is a matter of a few clicks in the Cloud Console. However, many customers prefer to manage their resource provisioning in an automated way using Terraform, OCI CLI, SDKs, or REST API for more consistency and efficiency. Providing the correct values in the OCI CLI command to…
Introduction OracleDB for Azure (or, Oracle Database Service for Azure) simplifies multicloud deployments by providing an Oracle-managed interconnect between your Azure and OCI accounts. Customers running their workloads on Azure can now keep the application on Azure and move the Database to Oracle Cloud to benefit from Cloud Automation, Exadata Service, Oracle RAC, and more.…

Introduction Oracle Cloud Object Storage is a regional service, i.e., objects are stored in a specific Oracle Cloud region. You can enable cross-region replication to automatically sync your data to a remote region for redundancy, providing protection from a regional outage. This blog post describes how to configure cross-region replication, use the replicated Object Storage…
Introduction To use High Availability features like Fast Application Notification (FAN), Draining, and Application Continuity, you need to create a custom database service and set the high availability attributes accordingly. This is not possible when using the default database service, which is the service with the same name as the PDB. Additionally, custom database services…
Introduction In addition to its data protection capabilities, Oracle Data Guard provides additional features for workload scale-out, backup offload, and online maintenance and upgrade operations. Some features require the Active Data Guard (ADG) option license, and some do not. Sometimes the “little things” you need to be aware of make the difference. This blog post…
Introduction Oracle Application Continuity is the high availability feature for your application. Database planned maintenance and outage events no longer impact applications availability. Do you want to learn how, try it, and implement it in production? But where to start from documentation, white papers, blog posts, videos, demos, and hands-on labs? This blog post gives…
Introduction Oracle Database is very well known for its high availability and disaster recovery capabilities using Oracle RAC and Oracle (Active) Data Guard. Maintenance operations like patching and upgrade, failures like database server or database instance crashes, and even complete data center outages have no to minimal impact on database availability. However, what happens on…
