SHARP-VLDB / ADB-S Cloud System Test Solutions /Automation Development group envisions & architects Large-scale, High Load/Volume, Massively concurrent Multi-tier simulation tools & Data-Centric applications to emulate Real-world Autonomous DB Cloud usage scenarios to detect product defects & architectural limitations. As a member of this group, you will Learn, Shape and Contribute towards these Cutting Edge Oracle Autonomous DB Services and On-prem features as they are designed (23c+) and gain state-of-the-art experience in Managing /Tuning/Debugging VLDBs emulating real-world production and cloud usage scenarios. You would be fully responsible for Designing, Implementing, Maintaining, and Enhancing Test Solution plans, Test Suites/Scripts, and Test methodologies that ensure exhaustive coverage of all these break-through features. Multi-tier Stress/Integration/System/Performance Test simulations are conducted in a State-of-the-art Cloud environment (grid of hundreds of servers) mimicking end-to-end high stress scenarios. This simulation effort involves complex DB Design (TB of data, Billions of rows, 1000s of tables), massively concurrent workload/query development (millions of transactions per sec, 1000s of queries per hour), extreme concurrency levels (5000-10000 parallel users) and boundary/destructive testing. The focus is primarily on high-end enterprise customer use-case scenarios (Ex: Bank of America, NYSE, Apple, LinkedIn, Dell, HDFC, SBI etc.) involving very large & extreme dimensions of testing.
Specifically, exciting opportunities currently exist to Innovate on our NextGen Oracle Autonomous DB Cloud Features & Services. Oracle Autonomous DB \xe2\x80\x93 Shared/Server-less is our Flagship \xe2\x80\x9cFully-Managed and Highly-Automated\xe2\x80\x9d NextGen DB Cloud Service, engineered to run natively on Oracle Cloud Infrastructure (OCI, Gen2) and Oracle EXADATA, providing the highest SLAs of Enterprise Cloud Availability, Scalability, Instant & Online Elasticity, Security and XTreme-Performance at lowest cost ! Autonomous DB (Server-less) supports different Workload Use-cases like:

• Autonomous Transaction Processing (ATP) - Operational and Business OLTP

• Autonomous Data Warehouse (ADW) - DW, Analytics and ML/Data Science

• Autonomous JSON Database - JSON-Centric Cloud Document Service

Autonomous DB is a highly \xe2\x80\x9cIntelligent Cloud\xe2\x80\x9d DB (powered by rich AI/ML algorithms) that helps it to: a) Self-Drive - Automatic Provisioning, Configuring, Scaling, Tuning and Patching b) Self-Secure - Automated Data Protection, Continuous Threat Detection & Online Security patches c) Self-Repair - Automatic System Failure detection and remediation with lowest downtime Oracle Autonomous Database is placed 1st for all 4 Operational Use-Cases and 1st/2nd for all 4 Analytical Use Cases in 2022 Gartner Critical Capabilities for Cloud DBMS Reports Oracle Autonomous Database Cloud (Shared Infrastructure) : https://www.oracle.com/autonomous-database/ https://www.oracle.com/database/technologies/datawarehouse-bigdata/adb-faqs.html https://www.oracle.com/in/autonomous-database/autonomous-data-warehouse/ https://www.oracle.com/in/autonomous-database/autonomous-transaction-processing/ https://www.oracle.com/in/autonomous-database/autonomous-json-database/
