  • Oracle Database System / Stress / Performance Test Development Group (VLDB)
  • Department Name : Database Product Development (PDO-DB-IDC)

    Location : Bangalore, Oracle India Development Center

    Department / Group Description

    Database Server Group in Product Development Organization is the crown jewel of Oracle Corporation, creating World s best Database Software technology used by hundreds of thousands of Enterprise, SMB and Cloud customers worldwide.

    The SHARP-VLDB team (Scalability, High Availability, Reliability, Performance) within the Database Server Product Development division is a well-respected, highly sought after group with a long track record of success.

    The group focuses on improving Scalability, High availability, Reliability and performance of Oracle Database Server products by Designing, developing and carrying out stress, integration, system and performance tests, which simulate complex real world scenarios on Very Large DBs (VLDB).

    The team discovers critical product defects and works closely with development groups to resolve them resulting in the highest quality of products before they get released to customers (Cloud and On-Premise).

    With over 200 dedicated Product Engineers distributed across the globe and working on a single mission, our group has been extremely instrumental in delivering highest quality Oracle Server products during every major release cycle.

    Job Description

  • 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 Enterprise DB usage scenarios to detect product defects & architectural limitations. Multi-tier Stress / Integration / System / Performance Test simulations are conducted in a state-of-the-art lab 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 : Yahoo, Amazon, Apple, LinkedIn, Dell etc.

    involving very large & extreme dimensions of testing. As a member of this group, you will Learn and Shape the Next-Gen / Cutting Edge Oracle DB features as they are designed (19c and beyond) and gain state-of-the-art experience in Managing / Tuning / Debugging VLDBs with thousands of concurrent users

    simulating real-world production / cloud systems. You will be fully responsible for Designing, Implementing, Maintaining, and Enhancing Test plans, Test Suites / Scripts, and Test methodologies that ensure exhaustive testing of all assigned software areas

    to ensure highest product quality by exposing defects, identifying regressions, and verifying resolutions. Requires strong interpersonal and technical skills to work effectively and efficiently with development staff and fellow colleagues

    to identify / debug and resolve software defects.

    Specifically, current opportunities exist in projects / features in below Enterprise DB areas like :

    1. Oracle Clusterware / ASM / RAC / ACFS,

    2. Oracle Data Appliance (ODA),

    3. ADG (Active Data Guard),

    4. Oracle Goldengate,

    5. Autonomous DB Cloud Services (ATP and ADW ADB Cloud Services)

    6. EXADATA / Engineered Systems,

    7. Oracle In-Memory DB,

    8. Oracle Next-Gen DB Storage Technologies etc.

    To help with the overall productivity of this group, you would develop Tools and Applications to Automate test flow and executions.

    This framework consists of tools for remote job execution and automated result checking / reporting.

    You would also be designing and developing highly stressful database workloads which include Physical and Schema design, Application Workload Design, Coding to generate relevant data and load, Executing the automated stress tests

    to exercise all kinds of database features along with monitoring tools / scripts
