 This section covers ZDLRA, ZFS, Recovery Service, and Backup Service
 
+Oracle Database Zero Data Loss Autonomous Recovery Service is a fully managed data protection service for Oracle Databases running on Oracle Cloud Infrastructure (OCI). Unique, automated capabilities protect Oracle Database changes in real time, validate backups without production database overhead, and enable fast, predictable recovery to any point in time. Low costs based on the amount of data being protected mean that zero data loss resiliency is available to organizations of any size and virtually any budget.
+
+Oracle Database Backup Cloud Service is a secure, scalable, on-demand storage solution for backing up Oracle databases to Oracle Cloud. The service complements your existing backup strategy by providing an off-site storage location in the public cloud.
+To use Oracle Database Backup Cloud Service you’ll subscribe to the service, install the Oracle Database Cloud Backup Module, and configure your environment to send backups to the cloud. You can then use familiar Recovery Manager (RMAN) commands to perform backup, restore, recovery, and maintenance operations. You can also use other tools for your cloud backups.

 # Disaster Recovery
 Deals with the technologies supporting disaster recovery, specifically Dataguard, but also covering services such as FSDR (Full Stack Disaster Recovery)
 
+Oracle Data Guard or Active Data Guard is the most effective solution to protect data of any enterprise and make it available on a 24x7 basis in the face of disasters and other calamities. Data Guard or Active Data Guard is essential for Mission Critical for Enterprise Database. Data Guard Cloud functionality includes MAA configuration, Data Guard role transitions and Monitoring.
+A database disaster is an event that causes DATA LOSS or SERIOUS DISRUPTION to applications and services. There can be various causes: power failure, hardware failure, cyber-attacks, natural disasters, fire, earthquakes, vandalism, human error, planned maintenance, etc. Most of the database server disasters cannot be prevented. Disaster Recovery provides SERVICE CONTINUITY in case of any geographical disasters or by planned outages by recovering or resuming the services from a geographically different location. This page will help you get started to understand some basic requirements for Disaster Recovery Opportunities with Data Guard/Active Data Guard.

 Specifically Oracle RAC and Application Continuity
 
-# Useful Links
+# RAC
+Oracle Real Application Clusters (RAC) allow customers to run a single Oracle Database across multiple servers in order to maximize availability and enable horizontal scalability, while accessing shared storage. User sessions connecting to Oracle RAC instances can failover and safely replay changes during outages, without any changes to end user applications, hiding the impact of the outages from end users.
+
+# Application Continuity
+Application Continuity (AC) is a feature available with the Oracle Real Application Clusters (RAC), Oracle RAC One Node, and Oracle Active Data Guard options that masks outages from end users and applications by recovering the in-flight database sessions following recoverable outages.
+Application Continuity masks outages from end users and applications by recovering the in-flight work for impacted database sessions following outages. Application Continuity performs this recovery beneath the application so that the outage appears to the application as a slightly delayed execution.
+Application Continuity improves the user experience for both unplanned outages and planned maintenance. Application Continuity enhances the fault tolerance of systems and applications that use an Oracle database.
+Transparent Application Continuity
+Transparent Application Continuity (TAC) transparently tracks and records the session and transactional state so that the database session can be recovered following recoverable outages.
+With no reliance on application knowledge or application code changes
+Transparency is achieved by consuming the state-tracking information that captures and categorizes the session state usage as the application issues the user calls.
