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 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 Oracle Application Continuity is the high availability feature for your application. Database planned maintenance and outage events no longer impact applications availability.

It offers automation for administration tasks like provisioning, patching, and backup. Hence, it is often compared to Oracle Autonomous Database on Shared Exadata Infrastructure. However, the differences are tremendous, especially (and not only) regarding database high availability. This is…
Introduction Oracle Data Guard provides synchronous data replication to standby databases to ensure zero data loss in case of a disaster. In addition, the standby database can be used to offload RMAN backups, serve read-only and read-mostly workloads, and ensure high availability for planned maintenance. This blog post provides the steps needed to patch Data…
Introduction The Oracle Cloud Events Service enables you to execute actions automatically based on state changes of your cloud resources. For example, a state change could be when the creation of the database is completed. An action could be sending an email notification or executing a function to implement post-creation tasks like creating users. If…
