Isolating table IO at the extent level
I'm in the process of updating an old 4GL program that gives me a
snapshot of my instance at the table level. I'm able to determine IO
operations against a table, but some of my tables may span multiple
chunks. Is there a way to determine table access at the chunk level? I
know that onstat -D gives IO ops at the chunk level and SMI gives IO ops
at the table level. Any ideas?
