Server, when database server is switched over, the upper layer application such as WEB application and APP applications needs to stop
Only processing data.
First, the state flag bit of WEB application is set to switching state, WEB by double center switching servers
After reading, the data that stopping processing being received.Due to WEB application can with front end user direct interaction,
When then WEB application determines that state flag bit is in switching state, can user's displaying for accessing of forward end it is friendly
Interface is reminded, the reason for current system can not be accessed is explained.
It is pre- that the state flag bit of WEB application is set to after switching state first by double center switching servers
After fixing time, the state flag bit that APP is applied is set to switching state.APP applications determine corresponding
State flag bit is switching state, then does not visit again back-end data base, and forward end application feedback current system
Switch over.
After second scheduled time, the state flag bit that double center switching servers apply database synchronization is set
For switching state.Database synchronization software reading state flag bit is switching state, it is determined that in a period of time
What is do not newly increased needs after archive log file, then proceeds by switching.
If it is preferred that the to be switched application is the second application of the described first application connection, described the
One application is connected with the 3rd using foundation, including：
Standby application state is switched to by main application state in the described second application, and the 3rd application is answered by standby
After being main application state with state switching, the connection of first application is pointed to is cut by pointing to second application
It is changed to sensing the 3rd application and is connected so as to realize that first application applies to set up with the 3rd.
For database server switching, specifically, the database synchronization on main database server should
With stopping, and the database synchronization on main database server is applied slave mode is switched to by major state.
Then the database synchronization application on standby database server is stopped, and by for the number on database server
It is main state according to storehouse synchronous applications by slave mode switching.
After database server switching, the sensing that need to apply APP is accordingly changed.Before switching, APP
Using main database server is pointed to, after switching, APP applications need to point to standby database server.The present invention
In embodiment, APP by LDAP using the database synchronization application is connected, then step S102 includes：
Described second application is switched to standby application state, and institute by described pair of center switching server by main application state
The 3rd application is stated after standby application state switching is main application state, first LDAP applied is (light
Measure directory access protocol, Lightweight Directory Access Protocol) connect and point to described in pointing to
Second application switches to sensing the 3rd application；Wherein, first application is APP applications,
Second application is database synchronization application.
After the completion of switching, the state flag bit of each application is set to by double center switching servers from switching state
Normal condition, and then the order set sets APP since the state flag bit that database synchronization is applied
The state flag bit of application, finally sets the state flag bit of WEB application.That is, step S103 includes：
The state flag bit that described pair of center switching server applies the database synchronization is set from switching state
For normal condition；
After 3rd scheduled time, the state flag bit that described pair of center switching server applies the APP
Normal condition is set to from switching state；
After 4th scheduled time, described pair of center switching server is by the state flag bit of the WEB application
