What is the purpose of session partitioning in PowerCenter?
Partitioning improves session performance by dividing the data into multiple threads for parallel processing.
Which transformation can cause performance bottlenecks if not optimized?
Lookup transformations can slow down performance when processing large data sets if not tuned properly.
What is the use of the Performance Details tab in Workflow Monitor?
It provides detailed session performance metrics like throughput, cache size, and bottlenecks.
Which cache setting can improve performance in Aggregator transformations?
Increasing cache size can reduce disk I/O and improve aggregation performance.
What is the effect of unconnected Lookup caching on performance?
Caching lookup data reduces repeated database access, improving performance.
Which of the following is a common cause of session failures?
Incorrect source or target definitions often cause session failures.
