I'm having a hard time interpreting the Buffer Waits section of my AWR reports. Looking at the example at http://www.neilkodner.com/images/skitch/buffer_waits-20100323-105423.jpg Certain tablespaces (cubs_data) have far more buffer waits, compared to others, even others(uworks_misc_index) with a higher amount of reads and writes. Our datafiles for each of the tablespaces are equally distributed across 3 volumes on a SAN. How can i interpret the buffer waits and explain them in order to potentially identify a problem?
