NEW QUESTION # 36
There are more than 10 concurrent users running queries on the DB system. The airport_geo table has been loaded successfully into a HeatWave cluster.
You want to run this query:
SELECT DISTINCT country FROM airport_geo ORDER BY country;
How do you determine whether the query is offloaded to the HeatWave cluster for execution?

A. Check the value of the hw_data_scanned global status variable.
B. View the Query Execution Plan of the query by running EXPLAIN.
C. Query the rpd_tables table in performance_schema.
D. Check the value of the rapid_query_offload_count global status variable.

Answer: D

Explanation:
To determine whether a query is offloaded to the HeatWave cluster for execution,check the value of the rapid_query_offload_countglobal status variable(Answer B).
* rapid_query_offload_count: This variable indicates the number of queries that have been offloaded to the HeatWave cluster. By checking its value before and after running the query, you can determine if the query was offloaded.
Steps:
* Connect to the MySQL DB system.
* RunSHOW GLOBAL STATUS LIKE 'rapid_query_offload_count';before and after executing the query to see if the count increases, indicating offloading.

NEW QUESTION # 37
You want to migrate an on-premises MySQL database to a MySQL DB system on OCI.
Which method provides the least amount of application down time when switching to the DB system?

A. Use the largest DB system shape to speed up the import.
B. Store the exported data in object storage to speed up the export and import.
C. Use inbound replication to synchronize the MySQL database transactions to the DB system.
D. Run MySQL Shell on an OCI compute instance to export and import the data for faster migration.

Answer: C

Explanation:
To migrate an on-premises MySQL database to a MySQL DB system on OCI with the least amount of application downtime,use inbound replication to synchronize the MySQL database transactions to the DB system(Answer C).
* Inbound Replication: This method involves setting up replication from your on-premises MySQL database to the MySQL DB system in OCI. This ensures that all changes and transactions are continuously replicated, keeping the DB system up to date with minimal downtime.
* Steps to Implement:
* Set up the MySQL DB system in OCI.
* Configure the on-premises MySQL database as the master and the OCI DB system as the slave.
* Start the replication process to keep the DB system synchronized with the on-premises database.
* When ready, switch the application to the DB system with minimal downtime as the data is already synchronized.

What is the possible cause?

A. The target DB system relay log file destination is full.
B. The missingGTID set has been archived to object storage and is no longer available.
C. The administrator has deleted the binary log files from the source DB system.
D. The channel has been disabled for more than 2 hours.

Answer: C
