ASM的io计算无法使用操作系统命令iostat获取,oracle提供了二中方法获取IO信息 方法一、ASMCMD管理命令iostat来获取磁盘信息 ASMCMD> iostat 5
Group_Name Dsk_Name Reads Writes
DATA DATA01 10975699823616 9430089424896
DATA DATA02 23240008613888 10401269573632

DATA DATA06 17284726155264 9867123035136
DATA DATA07 12121124231680 9439979880448

DATA DATA09 29592159839232 10762434184192
方法二、asm实例中的v$asm_disk_stat来获取信息
select group_number, disk_number, name, path, reads, writes, read_errs, write_errs, read_time, write_time, bytes_read, bytes_written
from v$asm_disk_stat
where group_number>0
order by group_number, disk_number;
