Database Cloud Service 1z0-1094-23 Oracle Study Notes

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.

While character set, database version, database size, and endian format influence migration options to OCI, tablespaces themselves do not directly affect migration options. The physical organization of data within tablespaces is typically reconfigured during the migration process based on the target environment's requirements.

Data Pump supports parallelism exclusively in the Oracle Database Enterprise Edition, leveraging the ability to perform multiple data-intensive operations concurrently. This feature enhances performance and efficiency during data export and import processes, particularly for large databases.

In the context of Oracle GoldenGate's Remote Apply process, a network latency of up to 16 ms is generally tolerated. This latency threshold is important for maintaining data consistency and ensuring timely data replication across distributed systems, particularly in high-availability and disaster recovery scenarios.
