Focuses on creation of indexes and optimized for response time are two characteristics of Autonomous Transaction Processing (ATP). According to the Oracle documentation,“Autonomous Transaction Processing is a database service that is optimized for transaction processing or mixed workloads. It delivers the best experience for mission-critical applications that require high performance, high concurrency, and low latency. Autonomous Transaction Processing automatically creates indexes, materialized views, and partitions based on the workload.” Additionally, according to the Oracle documentation, “Autonomous Transaction Processing is optimized for response time. It uses a combination of caching, in-memory columnar format, and result set caching to deliver fast response times.”

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).”

The goal of scale out high availability can be achieved by provisioning nodes with Real Application Clusters (RAC). According to the Oracle documentation6, “Oracle Real Application Clusters (RAC) enables you to scale out your database by adding nodes as needed without changing your application code. RAC also provides high availability by automatically recovering from node failures.” RAC allows multiple instances of Oracle Database to run on different servers while accessing a shared set of data files.

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.”

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.
