Engineered Systems Infrastructure - Management and Provisioning – Test Development

Group & Team Profile

SHARP-VLDB/System Test 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.

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. 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.

As a member of the team, you will have the opportunity to work on high scale test development and complete end-to-end automation of high scale applications on Oracle’s Engineered Systems platforms. This provides opportunities including :

Oracle Engineered Systems : Work on Oracle’s class of Engineered systems that include most optimized solutions across the stack - from most advanced processors to intelligent high speed storage (including flash and persistent memory), to complex and extreme speed network switches to the most advanced operating system (Oracle Linux) that offers the best platform to run the most advanced Database Server (Oracle Database). The family of engineered systems consists of Oracle Exadata , Oracle Database Appliance
Cross-Stack application development and validation across different layers of stack including Network, Storage and OS platforms . Develop expertise at each layer of the tech stack.
Complete Automation of large scale applications that are deployed across the layers of stack and orchestrated to depict real world complex deployment/execution scenarios & processes.
Responsible for testing Oracle Database Appliance , an engineered system to make it easy to deploy, operate, and manage.
You will also find an opportunity to do perform Oracle RAC, ASM and Oracle Clusterware implementations, deployments, GI upgrades and migration tasks . This is a golden opportunity to learn RAC advanced technologies in one of the BEST team in Server Technologies.
Oracle Real Application Clusters ( RAC ) is an option that provides high availability (HA) and scalability to the Oracle Database without requiring any application changes. There is no other solution in the market that provides all the features as Oracle RAC. Oracle RAC contributes immensely to the “autonomous” character of the Oracle Autonomous Database. New features such as Autonomous Health Framework and existing features such as Oracle Cache Fusion algorithms are continuously enhanced utilizing the latest in hardware innovations and industry trends such as cloud computing and machine learning.

As a member of the team, your responsibilities include but are not limited to:

Develop new test methodologies across the database/systems stack to fully tap the capabilities offered by underlying layers (including network, storage and OS platform) of Engineered Systems.
Deep dive into specific layers of Oracle RAC database and Systems stack to identify bottlenecks at a granular layer levels and improve product quality so as to achieve overall robustness and reliability of the whole System.
Build and enhance automated, flexible and re-usable test frameworks and applications for system testing at scale to expose product defects, regressions and verifying solutions.
Perform complete and end-to-end automation of System provisioning and management tasks including administration , deployment , patching , maintenance, installations , network, tech stack upgrades and designing/build test framework to test and meet maximum high availability requirements on Oracle Engineered Systems. Specific tasks include OS upgrade, firmware and driver patch validation, kernel upgrades/rollbacks, platform management software patching/rollback etc for the infrastructure.
Responsible for problem resolution of Oracle DBMS creating installation scripts and procedures troubleshoot network issues and resolve network connectivity issues.
Administration & Deployment of Oracle RAC (GUI & Silent Mode), ASM, and Oracle Clusterware Components on different OS platforms.
Perform adding and Deletion of Nodes, Workload Management, Administering Services, Oracle RAC/ASM Troubleshooting , etc.
Basic understanding in performance tuning like generating AWR, ADDM, ASH reports.
Review customer escalations and bridge testing gaps by enhancing existing test applications.
Ensure quality of new ease-of-use features to provide proactive, predictive, and lower risks to our customers.
Ensure quality of post-release patching by understanding new feature/enhancement and verifying various fixes. Log and track product defects as encountered.
Responsible for collecting and analyzing common trace files, network packet tracing, memory dumps, Oracle logs, RAC logs, analyze OS metrics for network, memory, processing and IO troubleshooting
Providing thought leadership to internal team members through internal webinars/meetings and act as the subject-matter-expert for the internal stakeholders to resolve technical deployment obstacles, spreading cloud-related knowledge to others in the organization.
