Hi, I can support your Oracle E-Business Suite and Oracle Database performance tuning work, focusing on query optimization, AWR/ASH review, SQL trace analysis, index management, and measurable before/after improvements. The best solution is to first review non-production performance data, top SQL, execution plans, wait events, AWR/ASH reports, indexes, table statistics, and EBS workload patterns. Then I’ll identify slow queries, tune SQL where possible, recommend index rebuild/redesign, review partitioning or compression options, and prepare safe changes for controlled production deployment. I’m comfortable with Oracle Database, Oracle E-Business Suite, Core/Apps DBA workflows, SQL*Plus, OEM/Cloud Control, SQL Tuning Advisor, Data Dictionary views, execution plans, SQL traces, AWR/ASH analysis, index tuning, statistics review, and production-safe performance optimization. Deliverables will include: * AWR/ASH performance review * Slow SQL identification * Execution plan analysis * Query tuning recommendations * Index audit and tuning * Statistics/partitioning review * Non-production validation * Production change plan * Before/after metrics * Concise tuning report I’ll focus on practical performance gains, low-risk changes, and clear documentation so response time, CPU usage, and database efficiency improve without disrupting business operations. Best regards Ankit

As a seasoned IT Specialist with over 17 years of diverse experience, I am confident in my capability to tackle even the most intricate performance issues your Oracle DB and E-Business Suite face. My primary area of expertise has been as a Database Engineer, which includes managing advanced database systems, optimizing query performance, index management, and data analysis - all significant aspects you're seeking for this project. I have invested heavily over the years in accruing thorough knowledge of Oracle databases, E-Business Suite, and other essential tools like SQL*Plus, OEM/Cloud Control, SQL Tuning Advisor and Data Dictionary views mentioned in your requirements. I also assure you that changes made will be meticulously documented, providing an appreciable 'before-and-after' analysis along with concise reports for transparency. I understand that 'performance tuning' here isn’t just about superficially enhancing performance but maintaining seamless operational workflow too. That's why my approach guarantees minimal disruption to your business operations even as I strive until we see measurable performance gains on your Oracle DBs. So let's collaborate and restore peak performance while ensuring uninterrupted business activities for you!

Hello, I’m interested in your Oracle Database performance tuning project. I have 4.2+ years of experience in enterprise Banking and FinTech applications, with hands-on experience in Oracle, SQL, Java backend systems, production support, application troubleshooting, performance optimization, and Root Cause Analysis. I can assist with: • SQL query analysis and optimization • Execution plan analysis and identifying bottlenecks • Index analysis and optimization recommendations • Oracle SQL troubleshooting • Application/database performance investigation • Production issue analysis and RCA • Before-and-after performance measurement and documentation I’m comfortable working in non-production environments first, establishing baseline metrics, implementing controlled changes, and validating measurable improvements before production deployment. I want to be transparent that my primary background is Java backend/application support rather than 10+ years of dedicated Oracle EBS/Core DBA administration. However, my Banking/FinTech production experience gives me strong exposure to enterprise Oracle environments and application-level performance troubleshooting. If you are open to an engineer with strong Oracle/application performance experience, I’d be happy to discuss your environment, current bottlenecks, and expected outcomes. Regards, Sumit Karanwal

I can help restore peak performance for your Oracle E-Business Suite instance. Optimizing query execution plans and managing indexes will significantly enhance response times and reduce CPU usage. I noticed you require clear before-and-after metrics, which is crucial for tracking improvements. My approach includes in-depth analysis of AWR/ASH reports and SQL traces, ensuring we target the right areas for tuning. With over a decade of experience in Core and Apps DBA roles, I'm comfortable with SQL*Plus and SQL Tuning Advisor. I've done similar work: [Community Events Web Application](#) where performance optimization was key to delivering a seamless user experience. Let’s chat about your specific challenges, and I can provide a free consultation to discuss the best approach. Regards, Dean I have done similar work: Modern Real Estate Investment Website

I have total 19 years of experience mainly in migration project in telecom billing domain dealing with oracle database. Also I have successfully handled data volumes of approximately 150 million records during migration activities, giving me strong practical experience in dealing with large datasets, SQL performance, database resource utilization, indexing, and migration-related performance challenges. For this engagement, my objective is straightforward: Identify the real performance bottlenecks, implement measurable improvements, and ensure that changes are introduced into production safely with minimal business disruption. My approach will focus on measurable results rather than assumptions—establishing a performance baseline first, tuning the highest-impact SQL and database structures, validating the results in non-production, and then carefully moving approved changes into production.

Hi, I have strong expertise in PL/SQL and MSSQL object tuning and performance optimization. I can analyze AWR/ASH reports, execution plans, SQL traces and SQL Tuning Advisor recommendations to identify CPU, I/O, and response-time bottlenecks. I’ll also audit indexes, optimize SQL and PL/SQL procedures, functions, packages, and queries, and evaluate partitioning or compression where measurable benefits exist. All changes will be tested in non-production first, with controlled production deployment. I’ll provide before/after metrics and a concise report documenting changes, rationale, and measurable improvements.

I am a Certified DBA with 25+ years of hands-on experience with Oracle Database and SQL Server, including extensive Core DBA and production database administration. I have worked extensively with performance troubleshooting, SQL tuning, execution plans, indexing, database health, and high-load production environments. I can help optimize your Oracle E-Business Suite environment with a structured, measurement-driven approach: • Analyze AWR/ASH reports, SQL traces and execution plans to identify CPU-intensive and slow SQL • Tune problematic SQL using appropriate optimizer strategies and SQL Tuning Advisor • Audit indexes, identify redundant/missing/inefficient indexes, and recommend rebuild/reorganization where justified • Evaluate partitioning, compression, statistics, and execution-plan improvements • Review database configuration and workload-related bottlenecks • Use SQL*Plus, OEM/Cloud Control and Oracle Data Dictionary views for detailed analysis • Test all changes in non-production before controlled production deployment • Establish clear before/after metrics for response time, CPU, I/O and throughput I will provide a concise tuning report documenting each change, the reason behind it, and measurable performance improvement. My priority is achieving tangible gains while maintaining Oracle EBS stability and minimizing production risk. I can start with a detailed health/performance assessment and quickly identify the highest-impact optimization opportunities.
