A financial services firm is migrating a 15TB Oracle 19c database from an on-premises AIX server to an Oracle Base Database Service on OCI running Oracle Linux. The business has mandated a maximum downtime of 1 hour. The migration team is using RMAN cross-endian transportable tablespaces. During the `CONVERT TABLESPACE` operation on the destination, the process fails. Which of the following is the most likely reason for this failure?
A retail company is planning a phased migration of its on-premises Oracle E-Business Suite database to OCI. They will use Oracle GoldenGate for replication to keep the on-premises and cloud environments synchronized for several weeks. During this period, some batch jobs will run on-premises while new reporting services run in the cloud, leading to potential data conflicts. Which GoldenGate feature is specifically designed to handle and resolve these types of data conflicts automatically during bi-directional replication?
A migration architect is configuring a Zero Downtime Migration (ZDM) response file for a logical online migration to an Autonomous Database (ADB). The source database uses Transparent Data Encryption (TDE) with a keystore managed by Oracle Key Vault (OKV). How should the TDE keystore details be configured in the ZDM response file for the target ADB?
A project requires migrating a 500GB Oracle 12c non-CDB database from an on-premises Linux server to a 19c PDB in an Exadata Cloud Service. The downtime must be less than 30 minutes. Which two of the following migration strategies are most suitable for this requirement? (Select TWO)
True or False: When using Oracle Data Pump to migrate a schema to an Autonomous Database (ADB), it is a mandatory prerequisite to pre-create the tablespaces in the target ADB before starting the import.
An administrator is performing a PDB remote clone from an on-premises 19c CDB to a target 19c CDB in OCI. The command fails with an ORA-65169 error. What is the most common cause for this error in a remote cloning scenario?
A data architect is designing an integration solution to load data from an on-premises Oracle database and flat files located in OCI Object Storage into an Autonomous Data Warehouse (ADW). The requirement is to perform complex joins and data quality transformations before loading the final, cleansed data into ADW. Which architecture represents the most efficient approach for this scenario?
You are consulting for a company migrating their Oracle Database from AWS RDS to an OCI Base Database Service. They have a 1 Gbps FastConnect between AWS and OCI. The database size is 2TB, and the business requires the migration to be completed with minimal downtime. They are using ZDM for the migration. During the initial data transfer phase (backup to OCI Object Storage), performance is much slower than expected. Which ZDM response file parameter should be tuned to improve the backup transfer performance over the high-speed network link?
A healthcare organization is migrating its on-premises Oracle 19c database, which contains sensitive patient data encrypted with TDE, to an OCI VM DB System. The security team has a strict policy that the TDE master keys must never reside on the DB System's local file system. Which two target database TDE configurations would satisfy this security requirement? (Select TWO)
A consultant is using SQL Developer's Database Migration Wizard to move a third-party MySQL database to an Oracle Autonomous Database. After connecting to the source and target, the wizard needs a place to store repository information, including the captured source database model and the generated Oracle model. Where is this migration repository created?
