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.

When using Autonomous Transaction Processing databases, certain object types such as database links (DB_LINK) and clusters may need to be excluded due to the managed nature of the environment and its security and architectural constraints. These exclusions help maintain the security, performance, and manageability of the Autonomous Database.

Oracle Data Integrator (ODI) supports the integration of heterogeneous data sources, including databases and flat files, within a single mapping. This capability allows for the joining of data from different source types, such as an Oracle database table and a flat file, and loading the combined data into a target database like DB2. ODI's flexible architecture and support for various technologies enable this seamless integration, facilitating complex data transformation and loading tasks across diverse data environments.

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.
