Description of drawings
Fig. 1 is the flow chart of the preferred embodiment of the present invention.
Embodiment
The inventive method is to realize master/slave data consistency by synchrodata between the active and standby machine.
With reference to the accompanying drawings, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, judge that by the detection of static data or dynamic data the conforming method step of active and standby machine is as follows:
Step S101: the data that need be consistent between active and standby are classified.
The data that need be consistent between active and standby are done classification, every type data are done consistency detection independently, make to help to reduce the complexity of master/slave data consistency detection property like this, and can provide more detailed master/slave data inconsistent reason.
In the present embodiment, data are divided into static data and dynamic data.Data are put in the static data assignment, must deposits, otherwise can influence the function of system.Dynamic data refers to can be by static data data that generate, that produced by service operation.
Static data is difficult for changing, and generally just change in configuration variation, and dynamic data changes frequently, constantly changes in the service operation process.Not labile static data and labile dynamic data are distinguished, help to reduce the complexity of master/slave data consistency detection property, and can provide more detailed master/slave data inconsistent reason.
According to the systemic-function demand, static data and dynamic data can further segment type respectively.
Step S102: the consistency detection of host-initiated master/slave data.
Main frame triggers under certain condition, starts the consistency detection of the type master/slave data.The user can set the condition of triggering as required, for example traffic carrying capacity can be set at trigger condition, according to the size triggering consistency detection of traffic carrying capacity.The size of this business that provides as the client of equipment is provided traffic carrying capacity, as the traffic carrying capacity of the traffic carrying capacity of making a phone call, online.
The consistency detection of master/slave data should avoid influencing the operation of regular traffic as far as possible, so the startup of consistency detection should just trigger under certain condition.The consistency detection of master/slave data should reduce the influence to regular traffic as far as possible, should just trigger startup under the less condition of traffic carrying capacity as far as possible.
In the present embodiment, the condition of triggering is as follows:
(1) for the consistency detection of static data, when traffic carrying capacity is less, triggers automatically, for example triggered less than 20% o'clock in the CPU occupation rate.
(2) for the consistency detection of dynamic data, fixed point triggers under the less condition of traffic carrying capacity, for example triggers during zero point every day.
(3) consistency detection of the consistency detection of static data and dynamic data can manually trigger by webmaster, detects the consistency of master/slave data immediately.
Step S103: after starting the consistency detection of master/slave data, the main frame time-out is active and standby synchronous to data.
Main frame is the detection starting point that assurance and standby host are consistent after the consistency detection that starts the type master/slave data, and main frame should suspend the active and standby synchronous of the type data.
For static data, it is unique approach that causes static data to change that configuration changes, and therefore in the process of doing the static data consistency detection, forbids that configuration changes.
For dynamic data, mainly be that service operation causes dynamic data to change, because can not forbid professional operation, in the process of doing the dynamic data consistency detection, main frame stops to standby host synchronous dynamic data, after consistency detection is finished, again with all dynamic datas to standby host synchronously once.
Step S104: main frame carries out the operation of consistency detection.
At the type data, main frame is collected data and calculation check value, and checking data (comprising data type, check value) is sent to standby host.
To the consistency detection of static data and dynamic data, main frame is collected static data and dynamic data respectively, calculates the CRC check value respectively, and checking data (comprising data type, CRC check value) is sent to standby host.
Step S105: standby host carries out the operation of consistency detection.
Standby host receives checking data, collects data according to data type, calculates the CRC check value equally, and compares with the CRC check value of main frame, if equate then think the master/slave data unanimity, otherwise thinks that master/slave data is inconsistent.Standby host sends to main frame with result's (comprising data type, active and standby whether consistent) of consistency detection.
Step S106: main frame is judged the consistency of master/slave data.
When master/slave data is consistent, execution in step S108; When master/slave data is inconsistent, execution in step S107.
Step S107: the main frame alarm, synchrodata is to standby host again.
Main frame is received the consistency detection result of standby host, if master/slave data is inconsistent, treatment measures comprise:
(1) alert to the webmaster report.
The inconsistent alarm of master/slave data has been arranged, before fault location, can check the current inconsistent alarm of master/slave data that whether has earlier, check whether the inconsistent alarm of master/slave data is arranged in the history alarm, if the inconsistent alarm of master/slave data is arranged, can check the master/slave data stationary problem earlier emphatically, to shorten fault location time.
(2) synchrodata again.
Standby host is again to main frame synchrodata again, and according to configuration, synchrodata also can continue to keep on-the-spot again.
Step S108: recover active and standby synchronous.
Main frame recovers the active and standby synchronous of related data, allows the active and standby synchronous of the type data again.
