ZDM for Oracle Database@Google Cloud migrations

We are pleased to announce that Oracle Zero Downtime Migration (ZDM) now supports all physical and logical migration workflows to Oracle Exadata Database Service on Dedicated Infrastructure (ExaDB-D) and Oracle Autonomous Database Serverless (ADB-S) on Oracle Database@Google Cloud. The various migration scenarios provide our customers with more choices to achieve their requirements for Oracle database migrations, including migrations between different database versions and platforms that require minimal downtime during the migration process.

About Oracle Database@Google Cloud and Oracle Zero Downtime Migration

Oracle Exadata Database Service on Dedicated Infrastructure (ExaDB-D) and Oracle Autonomous Database Serverless (ADB-S) on Oracle Database@Google Cloud provide built-in high availability, scalability, and performance by running on Oracle Exadata and Oracle Real Application Clusters (Oracle RAC), natively integrated in Google Cloud, hence, maintaining a low-latency connection to your Google Cloud applications.

Oracle Autonomous Database automates provisioning, tuning, patching, security, scalability, and availability, reducing operational costs and minimizing the risk of human errors. Oracle Autonomous Database can be deployed in minutes, allowing businesses to quickly launch applications and services.

Oracle Zero Downtime Migration (ZDM) is a free-of-charge migration solution trusted by customers worldwide that simplifies and automates Oracle database migrations, including those requiring minimal downtime. Following Oracle Maximum Availability Architecture (MAA) best practices, ZDM provides pre-validation and controllable automation for a single database or database fleet migrations to Oracle Database@Google Cloud.

Migration Workflows to Oracle Exadata Database Service

You can perform the following Oracle ZDM migration workflows to migrate you Oracle Database to Oracle Exadata Database Service on Dedicated Infrastructure (ExaDB-D) on Oracle Database@Google Cloud:

Physical Online Migration

The physical online migration workflow supports migrations between the same database versions and platforms. It uses direct data transfer and the “restore from service” method to create the target database, explicitly avoiding backing up the source database to an intermediate storage location. Oracle Data Guard keeps the source and target databases in sync to achieve a minimal downtime migration.

Logical Online Migration

The logical online migration workflow supports migrations between the same and different database versions and platforms. It uses Oracle Data Pump export and import to create the target database. Google Cloud Managed NFS Server provides an NFS file share to store the Data Pump dump files. Oracle GoldenGate keeps the source and target databases in sync to achieve a minimal downtime migration.

Physical Offline Migration

The physical offline migration workflow supports migrations between the same database versions and platforms. It creates the target database using Recovery Manager (RMAN) backup and restore. Google Cloud Managed NFS Server provides an NFS file share to store the RMAN backup files.
