Pass the Oracle Database Cloud Service 1z0-1094-23 Questions and answers with CertsForce

For migrations with Oracle Zero Downtime Migration, the source Oracle Database can be running on Linux x86-64 platforms. This platform is widely supported and commonly used for Oracle Database installations, providing a robust and stable environment for both the source databases and the migration processes facilitated by ZDM.

Oracle Cloud Infrastructure (OCI) Database Migration service supports a range of source database versions, including Oracle Database 19c and Oracle Database 11g. These versions are commonly used in enterprise environments and are supported for migration to OCI, enabling organizations to leverage the cloud's scalability, performance, and cost benefits.

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.

When using transportable tablespaces for database migration, it's crucial that the source and target databases have matching time zone versions and character sets. This ensures data compatibility and integrity, preventing issues related to time zone and character set discrepancies that could affect the migrated data.

Using the unplug and plug method for database migration to Oracle Cloud Infrastructure involves certain constraints, including the requirement for the source and target databases to have the same endianness and both need to be Container Databases (CDB). This method involves unplugging a pluggable database (PDB) from the source CDB and plugging it into the target CDB, necessitating compatibility in terms of endianness and database structure.

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.

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.

Oracle Zero Downtime Migration (ZDM) service host is supported on Oracle Linux 7. This platform is optimized for running Oracle software and provides a stable and secure environment for deploying ZDM, which facilitates seamless database migrations with minimal downtime. Oracle ZDM does not support Windows, IBM AIX, Red Hat Enterprise Linux, or Solaris platforms for its service host deployment.

When using the RMAN DUPLICATE command for database migration, the auxiliary instance must be started in NOMOUNT mode. This mode allows the auxiliary instance to be prepared for duplication without opening the database, ensuring that the data files are accessible and can be replicated to create a duplicate database.

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.
