Oracle 1z0-1094-23 - Oracle Cloud Database 2023 Migration and Integration Professional

SQL Developer Web allows the import of various file types, including Excel, AVRO, CSV Delimited, and JSON. This flexibility supports a wide range of data integration and migration tasks, enabling users to easily upload and integrate data from different formats into the database environment for analysis, reporting, and other purposes.

To migrate an on-premises Oracle Database to Oracle Autonomous Database, methods such as Data Pump Export/Import, Oracle Zero Downtime Migration, and PDB Unplugging/Plugging can be used. Data Pump facilitates structured data movement, ZDM enables continuous replication for minimal downtime migrations, and PDB Unplugging/Plugging allows for the seamless transfer of pluggable databases to the cloud.

When using the Cross-Platform Transportable Tablespace Backup Set for database migration, the target version of the Database Cloud Service must be 12.1 or later. This requirement is due to the features and capabilities introduced in Oracle Database 12c that support the transportable tablespaces functionality, enabling the efficient migration of tablespaces across different platforms and database versions.

For Oracle Database sources in ODI projects, the Reverse Knowledge Module (RKM) for Oracle is used for reverse-engineering database objects, and the Loading Knowledge Module (LKM) SQL to Oracle is used for extracting and loading data. These KMs enable efficient metadata capture and data integration from Oracle sources.

When migrating a target database with different endianness than the source database, the appropriate methods to use are RMAN DUPLICATE and RMAN CONVERT. RMAN DUPLICATE can be used in combination with conversion operations to create a duplicate database on a remote host with different endianness, whileRMAN CONVERT is used to convert data files between different formats, which is necessary when moving between platforms with different endianness.

The unplug/plug a PDB migration method requires source databases to be version 12c or later, where the multitenant architecture was introduced. Target databases must be 18c or later to support new features and enhancements, ensuring compatibility and successful migration of pluggable databases.

When migrating to Exadata Cloud Service, upgrading the source database may be required to ensure compatibility with the target environment. Exadata Cloud Service typically supports newer database versions, and upgrading ensures that the source database can leverage Exadata's advanced features and optimizations.

In Oracle Data Integrator (ODI), it is possible to join multiple source tables within a single mapping and load the result into a target table. This capability allows for the creation of complex data integration and transformation processes, where data from different source tables (such as table A and table B) can be combined and manipulated to populate a denormalized target table (table C), all within a single, cohesive mapping.

For Oracle Zero Downtime Migration (ZDM) to perform a successful database migration with the physical workflow, root user or SSH key-based access to both source and target database servers is required. This access ensures ZDM can execute necessary operations on the database servers, facilitating a smooth migration process.
