Online Pluggable Database (PDB) relocation allows for the movement of a PDB from one CDB to another with minimal disruption. It supports relocating a PDB with an ASCII character set to a CDB with the AL32UTF8 character set, enabling character set conversion. Furthermore, PDB relocation can achieve near-zero downtime when there is no version change between the source and target CDBs, enhancing operational continuity.

To extract data from Fusion SaaS applications and load it into Autonomous Data Warehouse (ADW) using Oracle Data Integrator (ODI), the essential topology elements include the Oracle (ADW) data server, File data server for handling flat files, and Object Storage to store and manage data files in the cloud. These components work together to facilitate the extraction, storage, and loading of data in an efficient and scalable manner.

In Oracle Cloud Infrastructure, compartments and policies provide a robust security control to separate and manage resources. Compartments help organize resources into logical groups, while policies define access permissions, ensuring that teams can access only the resources they are authorized to manage, in line with organizational security requirements.

Before migrating a source database using Oracle Zero Downtime Migration, certain prerequisites must be met, including enabling Archivelog mode for capturing all transactions and ensuring Transparent Data Encryption (TDE) is enabled for data security. These requirements help maintain data integrity and security throughout the migration process.

The dbms_cloud_admin package is used by Business Intelligence Cloud Connector (BICC) Loading Knowledge Modules in Oracle Data Integrator (ODI) when integrating with Autonomous Data Warehouse (ADW). This package provides administrative capabilities for managing cloud resources and services, facilitating efficient data loading processes.

To connect an on-premises Oracle Database to an Autonomous Database on Oracle Cloud Infrastructure (OCI) using Oracle Data Integrator (ODI) on Marketplace, VPN Connect and FastConnect are viable options. VPN Connect allows for a secure, privateconnection over the internet, while FastConnect provides a dedicated, high-bandwidth connection. Both methods ensure a reliable and secure data transfer path from on-premises systems to OCI.

Oracle Application Express (APEX) is a web-based, feature-rich development tool that resides in a low-code environment. It enables rapid development of scalable and secure applications, offering a wide range of functionalities that facilitate application design, coding, and deployment within a web browser without the need for extensive infrastructure.

When migrating a database with Oracle Zero Downtime Migration, supported backup mediums include Oracle Cloud Infrastructure Object Storage for cloud-based storage, Oracle Zero Data Loss Recovery Appliance for high-end backup and recovery solutions, and NFS Storage for network-attached storage options. These mediums provide flexible and reliable data storage solutions for database backups during migration.

Migrating a 19c Oracle Database from AWS RDS using RMAN backups involves several steps, including the use of the Oracle Secure Backup Cloud Module to facilitate RMAN backups directly to AWS S3. The data is then transferred from the S3 bucket to an OCI Object Storage bucket. Finally, the backup is restored from the OCI Object Storage bucket to an OCI Database Service instance, completing the migration process.

In the context of Oracle GoldenGate's Remote Apply process, a network latency of up to 16 ms is generally tolerated. This latency threshold is important for maintaining data consistency and ensuring timely data replication across distributed systems, particularly in high-availability and disaster recovery scenarios.
