take an average of this evaluation mode.It is a useful algorithm to use the F-score algorithm to evaluate both precision and recall rates . The PR of the molecule determines that the precision ratio (P) and recall (R) must be large at the same time to ensure that the F score values are larger. If the precision ratio or recall rate is very low, close to 0, the direct result of the PR value is very low, approaching 0, that is, F score is also very low.At this point we compare three algorithms, we
Dual-machine hot with two implementation modes, one is based on shared storage devices, the other is not shared storage devices, generally referred to as a pure software approach.
Dual-Machine hot standby based on storage sharing is the most standard scheme for dual-machine hot standby.
For this approach, two servers
