Buffer Hit Ratio | Oracle | How often a requested block has been | |
|
|
| found in the buffer cache without |
|
|
| requiring disk access. If the ratio is less |
|
|
| then 90 percent, investigate further. You |
|
|
| may need to increase cache size by |
|
|
| increasing db_block_buffer(8i) or |
|
|
| db_cache_size(9i). |

Bytes Transferred | LSI storage systems | Bytes transferred on a drive. | |
|

Bytes Transmitted | • | Storage systems | Number of bytes transmitted by the port |
(MB/Sec) | • Host (port for HBA card) | per second | |
| • NAS filer (IP port) |
