Looking at ASM views v$asm_disk_stat, v$asm_diskgroup_stat etc., I am trying to pull out disk statistics for I/O service times. It appears that this data goes back as a cumulative counter, back to ASM instance startup. Is there a way to reset these statistics ? Or some other view that has a more limited counter in time (like a few hours or so) ? -- //www.freelists.org/webpage/oracle-l
