Oracle SQL Loader: Parallel Data Loading for Optimal Performance (NQTX Tuning)

In this video, Durga from IT University explains how to effectively load data into an Oracle database using SQL Loader, focusing on parallel data loading techniques and troubleshooting performance bottlenecks. We dive deep into resolving NQTX contention, optimizing commit rates, and understanding the impact of `initrans` on database performance. Topics Covered: How can I improve SQL Loader performance for large data loads? What is NQTX contention in Oracle SQL Loader and how does it impact performance? How do I fix NQTX contention and optimize parallel data loading? What are the best practices for loading data in parallel into an Oracle database? How does the `initrans` parameter affect SQL Loader performance? How does SQL Loader parallel loading work, and what are its limitations? What is high watermark contention and NQFB contention in Oracle during data loading? How can I determine the optimal commit rate for SQL Loader to maximize performance? What are common wait events to look for during SQL Loader execution, and how do I troubleshoot them? What is the structure of block header and slots for transaction related information?
