Oracle Exam 1Z0-821 Topic 11 Question 65 Discussion

In this output, the statistics for interrupt (INTRS) are significant. Low interrupt numbers indicate greater efficiency in performance. If the interrupt numbers are high, then you might need to add more resources to the specific link.

Example:

# dlstat -r -i 1
