1z0-1094-23 Exam Dumps - Oracle Database Cloud Service Questions and Answers

In Oracle Data Integrator (ODI), projector components, like Aggregate and Distinct, limit the attributes available to succeeding components. Non-projector components, such as Sort, Filter, and Join, do not impose this limitation; they manipulate data streams without hiding attributes, allowing subsequent components in the mapping to access all available attributes.

In Oracle Zero Downtime Migration, themigrate databasecommand supports several parameters, including "-tgtroot" (specifies the target root directory), "-tdemasterkey" (defines the Transparent Data Encryption master key), "-sourceid" (identifies the source database), and "-sourcedb" (names the source database). These parameters are critical for configuring the migration to ensure security, identification, and proper handling of the source and target databases.

SQLcl, a command-line interface for Oracle Database, can utilize Data Pump Export/Import and the LOAD command to migrate databases or load data into Oracle Cloud Databases. Object Storage serves as a staging area for data files in both methods, facilitating efficient and scalable data transfer to the cloud environment.

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 Exadata Cloud Service is designed to consolidate numerous Oracle Databases, providing high performance, scalability, and reliability. It offers a cloud-based platform with the same Exadata optimizations found in on-premises deployments, making it ideal for large data center migrations to Oracle Cloud.

In Oracle Data Integrator (ODI), to isolate erroneous rows and recycle corrected rows in subsequent runs, flow control must be enabled with the RECYCLE ERRORS option set to TRUE. Additionally, having a primary key on the target table is essential for identifying and managing rows during the integration process, ensuring data integrity and facilitating error handling.

SQL Developer Web provides a web-based interface for Oracle Database management, including the ability to load JSON documents into Oracle databases on the cloud. This tool simplifies database tasks, making it accessible for users to manage data and perform migrations within a cloud environment.

Oracle Data Guard is the method that provides the least downtime for database migration. It ensures high availability, data protection, and disaster recovery for Oracle databases. By maintaining a synchronized standby database, Data Guard enables seamless role transitions and minimal downtime during planned maintenance, making it an optimal choice for migrations requiring continuous availability.

Oracle Zero Downtime Migration (ZDM) leverages several Oracle products and utilities in its migration workflows, including Oracle Data Pump and Oracle GoldenGate. Data Pump is used for high-speed data transfer and migration tasks, while GoldenGate facilitates real-time data replication and integration, allowing for seamless and efficient migrations to Oracle Autonomous Database with minimal downtime.

A Bastion host is used within a network, especially in a private subnet, to provide secure access to Oracle Cloud Infrastructure instances. It acts as a gateway, enabling controlled access to internal instances from an external network, thereby enhancing the security posture by limiting direct exposure of instances to the public internet.
