1z0-1094-23 Oracle Cloud Database 2023 Migration and Integration Professional Free Practice Exam Questions (2025 Updated)

Error ORA-00245 during Zero Downtime Migration of an Oracle RAC database typically indicates that the SNAPSHOT CONTROL file is not configured to use a shared location accessible by all RAC instances. This shared access is crucial for coordinated snapshot operations across the RAC environment.

SQL Developer Web was released in 2018, providing a browser-based interface for Oracle Database management and development tasks. It offers a convenient, web-based alternative to traditional desktop database tools, enhancing accessibility and user experience.

Oracle Zero Downtime Migration supports various Oracle Database Cloud Services as target databases, including Oracle Database Cloud Service, Autonomous Database, Exadata Cloud at Customer, and Exadata Cloud Service. These services offer scalable, high-performance database solutions, making them suitable targets for migrations aimed at enhancing infrastructure and taking advantage of cloud capabilities.

For migrating an on-premises 12c Non-CDB to the Cloud 12c, conventional Data Pump Export and Import and Transportable Tablespaces are viable methods. Data Pump facilitates the export and import of database objects and data, while Transportable Tablespaces allow the movement of entire tablespaces between databases, streamlining the migration process and reducing downtime.

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.

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.

Oracle Data Integrator (ODI) supports a wide range of knowledge modules, including those for various database platforms like IDB DB2, big data technologies like Spark and Hive, and cloud services like Autonomous Data Warehouse (ADW). This versatility allows ODI to integrate and transform data across diverse data environments and technologies.

Oracle Autonomous Database automates routine database tasks, offering high performance, reliability, security, and operational efficiency. Its self-driving, self-securing, and self-repairing capabilities reduce administrative overhead, making it ideal for modern data management needs.

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.

Oracle Application Express (APEX) is a web-based, feature-rich development tool that resides in a low-code environment. It enables rapid development of scalable and secure applications, offering a wide range of functionalities that facilitate application design, coding, and deployment within a web browser without the need for extensive infrastructure.

When migrating a TDE-encrypted database using RMAN DUPLICATE, it's crucial to copy the TDE wallet from the on-premises database to the Cloud DB system. This ensures that the cloud database can decrypt the data, as the encryption keys contained in the wallet are necessary for accessing the encrypted data.

Oracle Zero Downtime Migration supports logical and physical migrations to Autonomous Database using Oracle Cloud Infrastructure (OCI) Object Storage. Logical migrations involve data extraction and loading using tools like Data Pump, while physical migrations involve moving database files directly. Both methods can be performed online or offline, with OCI Object Storage serving as an intermediary storage solution.
