Oracle 1z0-1094-23 Based on Real Exam Environment

When migrating an Oracle Database to Oracle Cloud, key parameters in the export command can include FLASHBACK_TIME=SYSTIMESTAMP for point-in-time consistency, version=latest to ensure compatibility with the target database version, exclude=statistics to improve performance by excluding statistics, and metrics=yes to enable diagnostic metrics during the export process. These parameters help optimize the migration for performance, compatibility, and diagnostics.

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.

The error ORA-19914 indicates encryption issues during RMAN backup to cloud storage. Enabling encryption with "SET ENCRYPTION ON" without a proper encryption key or missing the Object Storage encryption-at-rest key can lead to this error. Ensuring encryption keys are correctly configured and accessible is crucial for successful RMAN backups to the cloud.

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.
