An Autonomous Database with the workload type Data Warehouse, Transaction Processing, JSON or APEX is a prerequisite of running APEX on an Autonomous Database. According to the Oracle documentation, “Oracle Application Express (APEX) is a low-code development platformthat enables you to build scalable, secure apps with world-class features that can be deployed anywhere. APEX is preconfigured and fully managed in Oracle Autonomous Database (ADB). You can use APEX on any Autonomous Database workload type: Data Warehouse (ADW), Transaction Processing (ATP), JSON (AJD), or APEX (APEX).”

 Exadata Cloud Service and Autonomous Database are two target database environments that provide both high availability (HA) and disaster recovery (DR) options in the cloud. Exadata Cloud Service is a fully managed Oracle Database service that runs on Exadata infrastructure in the cloud. It offers high performance, scalability, availability, security, and reliability for all types of database workloads. It also supports various HA and DR options, such as Oracle Real Application Clusters (RAC), Oracle Data Guard, Oracle Active Data Guard, Oracle GoldenGate, and Oracle Zero Data Loss Recovery Appliance Cloud Service. Autonomous Database is a self-driving, self-securing, and self-repairing cloud database service that automates provisioning, configuring, securing, tuning, scaling, patching, backing up, and repairing of databases without human intervention. It also provides built-in HA and DR features based on Oracle Maximum Availability Architecture (MAA), such as transparent application continuity, automatic failover to standby databases or regions, automatic backups to object storage, point-in-time recovery using restore points or backups.

Loading data using FTP is not an option in Database Actions to load data into Autonomous Database. According to the Oracle documentation5, “On the Database Actions Data Load pageyou can choose to load data from a file on your local device, from cloud storage, or from a database. You can also choose to explore the data in your Oracle Autonomous Database.” There is no mention of FTP as a source for loading data.

OCI Block Volumes is the service used by default by the MySQL Database Service to store user data to make it more resistant to failures. OCI Block Volumes provides high-performance block storage volumes that can be attached to MySQL DB systems running on OCI Compute instances. Block volumes are always encrypted at rest using AES-256 encryption keys. Block volumes also support backup and restore operations using snapshots or clones that can be used for disaster recovery or testing purposes.

These two statements are true regarding MySQL Database Service HeatWave. According to the Oracle website3, “HeatWave is a high-performance in-memory query accelerator for MySQL Database Service on Oracle Cloud Infrastructure. It is designed to accelerate analytics workloads (OLAP) and increase the performance of your MySQL databases by orders of magnitude.” Additionally, according to the Oracle website4, “HeatWave uses machine learning to automate operations, increasing DBA productivity and reducing costs. HeatWave AutoML enables developers and data analysts to build, train, deploy, and explain machine learning models in MySQL HeatWave without moving data to a separate machine learning service.”

This statement is not a prerequisite for patching Grid Infrastructure or database homes when using the console. According to the Oracle documentation8, “Before you patch Grid Infrastructure or database homes, ensure that the following prerequisites are met: All database compute nodes of the VM cluster are up and running. The /u01 directory on the database host file system has at least 15 GB of free space for the execution of patching processes. The required patch is available on the Control Plane server.” This means that Oracle Clusterware must be up and running on the VM cluster before patching, not down.

Compartments are a feature that allows you to logically group and isolate your Oracle Cloud Infrastructure resources. According to the Oracle documentation2, “Compartments are a fundamental component of Oracle Cloud Infrastructure that allow you to create a heterogeneous collection of resources for organization, security isolation, and access control.To learn more about compartments, see Managing Compartments . Organize your cloud resources in logically separate compartments, for the purposes of measuring usage and billing, controlling access, and isolating resources.”

Nosql-keys is not a resource type for NoSQL Database Cloud Service. According to the Oracle documentation, “Oracle NoSQL Database Cloud Service supports three resource types: nosql-tables, nosql-rows, and nosql-indexes. These resource types are used to define policies that control access to NoSQL tables and data.”

Use graphical interfaces and configuration for building web applications is a main feature of APEX’s low code platform. As mentioned earlier, according to the Oracle website, “Oracle APEX is a low-code development platform that enables you to build scalable, secure enterprise apps with world-class features that can be deployed anywhere. With APEX, you can create modern web apps with minimal coding using intuitive graphical interfaces and declarative configuration.”

Hadoop clusters cannot be run on Oracle Database 19c. Hadoop is a framework for distributed processing of large data sets across clusters of computers using simple programming models. Oracle Database 19c is a relational database management system that supports SQL and PL/SQL queries and transactions. Hadoop clusters require a different architecture and storage model than Oracle Database 19c. Oracle Database 19c does not support the Hadoop Distributed File System (HDFS) or the MapReduce programming model.

This statement is true about MySQL Database Service. According to the Oracle documentation3, “MySQL Database Service is a fully managed Oracle Cloud Infrastructure native service, developed, managed, and supported by the MySQL team in Oracle. Oracle automates tasks such as backup and recovery, and database and operating system patching. You are responsible solely for managing your data, schema designs, and access policies.”

Data Labeling is not a built-in tool provided by Autonomous Database. According to the Oracle documentation4, “Autonomous Database includes built-in tools that you can enable and disable when you provision or clone a database, or at any time for an existing database.” The list of built-in tools includes Oracle APEX, Database Actions, Graph Studio, Oracle ML User Interface, Data Transforms, Web Access (ORDS), MongoDB API, and SODA Drivers. Data Labeling is not among these tools.
