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

Theogg_latencyview is used to measure the replication latency between the source and target when using the automatic heartbeat table feature in Oracle GoldenGate. This view provides valuable insights into the timing and performance of data replication processes, helping administrators monitor and optimize the GoldenGate replication environment.

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.

For migrating a non-TDE-encrypted 19c CDB to Database Cloud Service using RMAN and backups stored in OCI Object Storage, the "instantiate from backup" option simplifies the process. This method automatically handles the necessary encryption for the cloud environment, streamlining the migration and ensuring compliance with cloud security standards.

For RMAN DUPLICATE operations, knowing the source database's listener port is essential for network connectivity, and the database unique name identifies the specific database instance for duplication. These pieces of information ensure RMAN can connect to and accurately identify the source database for cloning.

Data Pump can utilize Dumpfile for unloading and loading data, where data is exported to and imported from binary dump files. Network mode allows Data Pump to transfer data directly between databases using database links, without the need for intermediate dump files, facilitating efficient data migrations and consolidations.

To enable Change Data Capture (CDC) in Oracle Data Integrator (ODI) for a data store, you need to start the journaling process by adding the data store to CDC and then starting the journal. This process initializes CDC for the specified data store, allowing ODI to track and capture data changes. Configuring journalizing options and ensuring primary keys are defined are also important steps, but the critical actions are adding the data store to CDC and starting the journal.

Oracle Zero Downtime Migration leverages Oracle technologies such as Data Guard for data replication, Recovery Manager (RMAN) for database backup and recovery, and SQLNet for network communication. These technologies work together to enable a physical online migration workflow, ensuring data consistency and minimizing downtime during the migration process.

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.

In Oracle Database architecture, a Container Database (CDB) can contain one or more Pluggable Databases (PDBs). This multi-tenant architecture allows for the efficient management of multiple databases within a single container, optimizing resource usage and simplifying database administration.

Data Pump can move data to the cloud by importing from a dump file stored in Oracle Cloud Infrastructure (OCI) Object Storage or directly from an Oracle Database using a database link. These methods allow for efficient data transfer to the cloud, with the dump file method providing a way to stage data in OCI Object Storage and the database link method enabling direct data transfer between databases.
