When changing synchronic command is issued to the client；The target data is to be stored in server and need and the visitor
The data that the data of family end local cache are consistent.
If some client is registered as global buffer listening mode, server monitors the total data in server, when
When data in server change synchronic command is issued to the client.
If some client is registered as automatic mode, server is monitored according to local data listening mode or global buffer
Pattern is that client issues synchronic command, and can be carried out between local data listening mode and global buffer listening mode automatically
Switching.I.e. caching monitors the client that strategy setting is automatic mode, and the caching of actual use is monitored strategy and can be serviced
Device automatically switches between local data listening mode and global buffer listening mode.
Specifically, server can according to the carrying out practically situation of itself to be registered as automatic mode client it is specific
Caching is monitored strategy and is automatically switched.
In a feasible real-time example, server participates in the statistic of the data of buffer service according to it and is cut automatically
It changes.If statistic is excessively high, it is switched to local listening mode；If statistic is relatively low, it is switched to global buffer listening mode.
In another feasible real-time example, server is automatically switched according to the operating load of itself.If operation is negative
Lotus is excessively high, then is switched to local listening mode；If operating load is relatively low, it is switched to global buffer listening mode.
