| Blk_lost_count |
Indicates the number of blocks that were lost during transfer from one Oracle instance to another. |

Ideally the value of this measure should be zero. A high value is indicative of network problems. The use of an unreliable IPC protocol such as UDP may result in the value for global cache blocks lost being non-zero. This ratio should be as small as possible. Many times, a non-zero value for global cache blocks lost does not indicate a problem because Oracle will retry the block transfer operation until it is successful. |
