Oracle Database Tips by Donald BurlesonApril 10, 2015

Question:  What does the v$iostat_network view do?  Can you show an example script using v$iostat_network?

Answer: The Oracle v$iostat_network view is new in 11g release 2.  It shows I/O wait times on network traffic, similar to SQL*Net roundtrip metrics.
