Oracle Performance: SQL Loader Initrans Explained (Parallel Loading Optimization)
Показать описание
In this video, we will demonstrate how to improve SQL Loader performance in Oracle by tuning the Unitrans parameter. We cover the impact of Unitrans on parallel data loading, how to avoid table rebuilds, and the relationship between Unitrans and commit rate. Learn how to optimize your data loading process and resolve NQTX contention for faster performance.
*Topics Covered:*
* How can I improve SQL Loader performance by tuning Unitrans?
* What is Unitrans in Oracle, and how does it affect data loading speed?
* How do I increase Unitrans in Oracle tables and indexes?
* What is the relationship between Unitrans and commit rate in SQL Loader?
* How can I avoid rebuilding tables after increasing Unitrans?
* What is the impact of setting high Unitrans values on database storage?
* How do I rebuild indexes in Oracle to ensure Unitrans changes take effect?
* How does Enqueue Transaction Contention (NQTX) impact parallel data loading?
* When should I increase Unitrans in Oracle to improve performance?
* How to identify the magnitude of NQTX contention in Oracle?
