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.

Installing Oracle Zero Downtime Migration (ZDM) software requires a system with at least 8 GB of RAM to ensure adequate performance. Additionally, specific Linux packages, including "glibc-devel" and "expect," must be installed to satisfy dependencies that ZDM components might have, ensuring a successful installation and operation of the ZDM service host.

ETL stands for Extract, Transform, and Load. This process involves extracting data from various sources, transforming it into a format suitable for analysis and reporting, and then loading it into a target data warehouse or database. ETL is a fundamental component of data integration and business intelligence processes, facilitating the consolidation and optimization of data for decision-making purposes.

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.
