It moves and records it and start time and then in step 420 generate the ticket of server, ticket can have the server
Weight, weight can be used for being compared with other machines.Then, in step 430, the starting of server inquiry association machine
Between and ticket.Here association machine can be connected with the server, can upgrade as host or be downgraded to standby host its
His server.In step 440, the starting time of server is compared with the starting time for being associated with machine inquired, point
For three kinds of situations:
(1) if the starting time of the server is earlier than the starting time for being associated with machine, method 400 proceeds to step
360, the state for updating the server is Host Status, and in step 470 unlatching port, service is monitored in starting；
(2) if later, for example, in one embodiment, it is (big that a threshold value can be set in the starting time of the server
In or equal to 0 any time value, such as 1 second), be later than the starting time of association machine more than the threshold when the starting time of server
When value, it is believed that the starting time of server, at this moment method 400 proceeded to step 480 later, and the state of the server is updated to
Standby host；
(3) if the starting time of server is identical with the starting time for being associated with machine, for example, in one embodiment,
When the two difference is within given range, it is believed that the two is identical, then method 400 proceeds to step 450, further relatively services

The weight of device, weight can be used for being compared with other machines.Then, in step 530, the starting of standby host inquiry association machine
Time and ticket.Here association machine can be other servers being connected with the server, such as host.In step 540,
The starting time of server is compared with the starting time for being associated with machine inquired.Comparison result is divided into three kinds of situations:
(1) if the starting time of server is later than the starting time of association machine (for example, corresponding host), method
500 proceed to step 460, and the state for updating the server is standby host state；
(2) if the starting time of server earlier, for example, in one embodiment, a threshold value can be set and (be greater than
Or any value equal to 0, such as 1 second), when the starting time of server being more than the threshold value earlier than the starting time of association machine,
Think starting time of server earlier, at this moment method 500 proceeds to step 580, is host by the server updating；
(3) if the starting time of server is identical with the starting time for being associated with machine, for example, in one embodiment,
When the two difference is within given range, it is believed that the two is identical, then method 500 proceeds to step 550, further relatively services
The ticket weight of device and the ticket weight for being associated with machine, if the ticket weight of server is lower, method 500 is advanced
To step 560, the state for updating the server is Host Status；Otherwise, method 500 proceeds to step 580, which is upgraded
For host.
It should be noted that it is similar with method 400, after executing method 500, if as a result, current server liter
Grade be host, then correspondingly by it is corresponding association machine Status Change be standby host state.In addition, it is necessary to explanation, such as
Fruit inquires the starting time (for example, association machine not yet starts) less than association machine in step 530, then will can directly be somebody's turn to do
The state of server is updated to Host Status, because currently only having this server available.
Fig. 6 shows the flow chart of the method 600 of server according to yet another embodiment of the invention.Method 600 is shown
A part of server process performed when being under standby host state.In step 610, standby host inquires Host Status, then exists
Step 620 judges whether Host Status normal, if Host Status normally if continue；Otherwise current standby host is upgraded into host,
The process flow of current standby host is exited, and enters the process flow of host.Continuation method 600, in step 630, standby host inquiry master
The service snapshot of machine, and in step 640, judge whether the service snapshot of the host inquired is consistent with local service snapshot,
If the service snapshot of host is different from local express photograph, the service SNAPSHOT INFO of host is synchronized to local in step 650, and
Update local service snapshot；If identical, step 610 is returned to.
