Q & A
What is the primary purpose of Oracle Database?
-Oracle Database is designed to provide flexible and cost-effective management of information and computing applications, particularly for large enterprises that require extensive database systems. It is built to handle both relational and non-relational data, such as JSON, XML, and spatial data.
What is the significance of Oracle Database 19c in the context of previous versions?
-Oracle 19c is a major release that supports both relational and non-relational data. It improves scalability, performance, and data access with support for new features and functionalities that are optimized for modern business needs, such as autonomous database capabilities.
What are the key features introduced in Oracle 12c?
-Oracle 12c introduced multi-tenant architecture, which allows multiple databases to be managed under a single container. This version also brought significant improvements for cloud integration and provided 2,500 new features, including support for hybrid cloud environments.
How did Oracle 11g improve query handling?
-Oracle 11g introduced 'Query Timeout' features and improved resource management, allowing administrators to set thresholds for query execution. Queries exceeding these limits could be automatically halted, helping manage system performance and preventing resource overload.
What does the term 'autonomous database' mean in Oracle 18c and beyond?
-An 'autonomous database' refers to a self-managing and self-repairing database system. It automatically handles tasks such as patching, tuning, and backup, reducing the need for manual intervention and improving efficiency and reliability.
What is the importance of 'Hybrid Partitioning' introduced in Oracle 11g?
-Hybrid Partitioning allows Oracle to combine internal database partitions with external partitions from different storage sources. This feature simplifies data management and integration with external systems while offering cost-effective storage solutions.
Can you explain the architecture of Oracle Database 19c?
-Oracle 19c's architecture is designed for scalability and performance. It uses an instance-based architecture where each instance consists of memory and background processes. The database can be configured for high availability using Oracle Cluster configurations to provide a fault-tolerant and highly scalable environment.
What is the role of the 'Listener' in Oracle Database?
-The Listener in Oracle Database is a server-side process that manages incoming client connections. It listens for client requests, establishes connections, and directs them to the appropriate Oracle Database instance for processing.
How does Oracle Database handle high availability and disaster recovery?
-Oracle Database offers high availability and disaster recovery through features like Oracle Data Guard, which maintains a standby database to take over in case of a failure in the primary database. Data Guard helps minimize downtime and ensures business continuity.
Why should businesses consider upgrading to the latest Oracle Database versions?
-Upgrading to the latest Oracle Database versions ensures ongoing support, improved security, better system performance, and access to new features. Older versions may lack support, leading to security risks and compatibility issues with new hardware and operating systems.
