Arvind Toorpu

Hello, I’m Arvind Toorpu, an Oracle Certified Professional (OCP) currently working as a Cloud Ops DBA manager with over 13 years of diverse experience in architecting, implementing, and administering databases. My expertise spans across Oracle, SQL Server, MySQL, and PostgreSQL, among others, in both production and non-production environments. I have worked extensively with various operating systems, including Red Hat Linux, HP-UX, Sun Solaris, IBM AIX, and Windows Server.

As a passionate database professional, I specialize in performance tuning, database migrations, high availability architecture, and implementing disaster recovery solutions. Throughout my career, I have led major projects, including the migration of hundreds of databases to cloud platforms like AWS, Azure, and Oracle Cloud Infrastructure (OCI). My roles have ranged from hands-on database management to leading teams in cloud operations, where we’ve configured and optimized complex database environments to meet business needs. I have a strong background in capacity planning and resource allocation, ensuring that database resources are effectively utilized while managing costs through strategic cost management and cost optimization. My expertise in data modeling and query optimization enhances system performance, while my troubleshooting skills enable me to provide 24/7 support, ensuring operational excellence and reliability

I am committed to continuous learning and enjoy sharing my knowledge with the community. I regularly write about my experiences and insights on database management, cloud migrations, and best practices on this blog and in other tech forums. My goal is to help others navigate the evolving landscape of database technologies, leveraging my practical insights and deep technical expertise.
When I’m not managing databases, I’m exploring new technologies, enhancing my skills through certifications, and engaging with the tech community. I hold certifications in AWS Cloud Solutions Architecture, Oracle Autonomous Database, and other advanced database security practices.

Cloning Master Admin User Permissions in Amazon RDS for SQL Server with Fine-Grained Control

This article explores how to securely clone the master user permissions in Amazon RDS for SQL Server using a custom stored procedure, usp_rds_clone_login. It outlines a step-by-step process to generate, review, and apply a script that replicates server- and database-level access from the master user to a new login without directly exposing elevated credentials. The guide emphasizes the principle of least privilege, supports named account management, and enables transparent, auditable permission handling for DBAs and applications. Designed for secure and scalable environments, this solution enhances operational security while maintaining administrative flexibility in Amazon RDS.

Question of the Day

Query Plan Regressions --

For the Question of the day, I am going to go deep, but try to be more clear, as I feel like I didn't give enough info last time, leading folks to guess the wrong answer... :) For today's question:  You’re troubleshooting a performance issue on a critical stored procedure. You notice that a previously efficient query now performs a full table scan instead of an index seek. Upon investigating, you find that an NVARCHAR parameter is being compared to a VARCHAR column in the WHERE clause. What is the most likely cause of the query plan regression?
