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.

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.

Oracle Native Network Encryption and TDE are security measures that are implemented out-of-the-box, and are included if you are not using BYOL licensing with Exadata Cloud@Customer. According to the Oracle documentation5, “Oracle Native Network Encryption encrypts all data sent over the network between database clients and servers using industry-standard encryption algorithms.” Additionally, according to the Oracle documentation6, “Transparent Data Encryption (TDE) enables you to encrypt sensitive data, such as credit card numbers, stored in tables and tablespaces.”

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.

Groups is an Oracle Cloud Infrastructure (OCI) Identity and Access Management (IAM) capability that helps you to organize multiple users into teams. According to the Oracle documentation4, “Groups are collections of users who need the same type of access to a particular set of resources. You can use groups to organize users and apply policies to them as a group.”

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 are two statements that are true when deciding which Oracle Cloud Infrastructure (OCI) region to register an Exadata Cloud@Customer infrastructure in. According to the Oracle documentation5, “When you register an Exadata Cloud@Customer infrastructure in an OCI region, consider any business policies or regulations that preclude the use of a particular region.” This means that you should be aware of any legal or compliance requirements that might limit your choice of OCI regions for Exadata Cloud@Customer. According to the Oracle documentation6, “Consider the physical proximity of the region you register the infrastructure in to your data center. The closer they are physically located, the lower the network latency between them.” This means that you should also consider the network performance and availability when choosing an OCI region for Exadata Cloud@Customer.

OCI REST APIs and OCI Command-line Interface (CLI) are two methods that you can use to create or modify Oracle Cloud Infrastructure resources. According to the Oracle documentation, “The Oracle Cloud Infrastructure APIs are typical REST APIs that use HTTPS requests and responses. You can use these APIs to interact with your cloud resources programmatically.” Additionally, according to the Oracle documentation, “The OCI CLI is a tool that enables you to interact with Oracle Cloud Infrastructure services from the command line.”

Assess is the security control area that determines if there is sensitive data in a system. According to the Oracle documentation2, “The Assess security control area includes activities that help you identify and classify sensitive data, assess your security posture, and monitor compliance with security standards and regulations.”

Oracle Database 19c is the final release supporting the non-CDB architecture. According to the Oracle documentation1, “Starting with Oracle Database 21c, non-CDB architecture is desupported. You must upgrade a non-CDB Oracle Database to a PDB on a CDB.” A CDB is a container database that can host multiple pluggable databases (PDBs) that share the same resources and memory.

Regulations that prevent moving data into the public cloud and putting data in the cloud would break data residency rules are two typical reasons why customers cannot move their database into the public cloud. Some organizations may have legal, compliance, or business policy requirements that restrict where their data can be stored or processed. For example, some regulations may require that data be stored within a certain country or region, or that data be encrypted or anonymized before being transferred to the cloud. Moving data to the public cloud may violate these regulations or introduce additional risks or costs for the customers.

AutoUpgrade is the Oracle recommended way to upgrade databases. According to the Oracle documentation, “AutoUpgrade is an Oracle-supplied tool that automates the upgrade process for Oracle Database releases 12.2, 18c, and 19c. AutoUpgrade can upgrade multiple databases in parallel and can also perform cross-platform migrations. AutoUpgrade is the recommended tool for upgrading your database.”

ORDS stands for Oracle REST Data Services, which is a Java application that enables developers to access and manipulate data in Oracle Database using RESTful web services. According to the Oracle documentation2, “Oracle REST Data Services (ORDS) bridgesHTTPS and your Oracle Database. A mid-tier Java application, ORDS provides a Database Management REST API, SQL Developer Web, a PL/SQL Gateway, SODA for REST, and the ability to publish RESTful Web Services for interacting with the data and stored procedures in your Oracle Database.”
