Load is smaller；When the garbage reclamation frequency of the concentrating type system is greater than or equal to predetermined threshold value, it is determined that the concentrating type system
Load it is larger.
Since external request can generally be related to multiple business, the corresponding business processing of some external requests is got up very simple
It is single, for example check that some data whether there is；And the corresponding business processing of some external requests is got up unusual complexity, such as
Then inquiry mass data is ranked up and exports to the mass data of inquiry.So cannot be simply by the number of external request
Amount judges the load of the concentrating type system, is judged in embodiments of the present invention by the garbage reclamation frequency of concentrating type system
The load of the concentrating type system.
When in the heap memory during the concentrating type system is idle or the concentrating type system free memory can not be distributed, the collection
Group's formula system can trigger garbage reclamation.Due to using the user of internet more and more at present, so the concentrating type system occurs
Idle state is few, which triggers garbage reclamation when generally can not all distribute free memory in heap memory.
When the corresponding business processing of an external request gets up relative complex, server can call more method, root
More variable and object are handled according to the method for calling, so, can be quickly reached in the heap memory of server can not distribute it is available
The case where memory, to trigger garbage reclamation.When the corresponding business processing of an external request is opposite gets up simple, server
The quantity of the method for calling can be less than the quantity for the method that complicated business calls far away, and the variable that is related to of simple business and
The quantity of object can also be less than the quantity of variable and object that complicated business is related to far away, so, when external request is corresponding
The number for triggering garbage reclamation when business processing gets up relatively easy in server can be relatively fewer, thus, it is possible to use rubbish
Recycling frequency weighs the load of the concentrating type system, and judges that the load of the concentrating type system is big using garbage reclamation frequency
It is small, improve the accuracy that access server judges the load of the concentrating type system.
Step 203：The external request that access server sends client is handled, and executes step 206；
Specifically, which loads the first class file for handling external request for itself including, by adding
The external request that the first class file carried sends client is handled.
Wherein, in JAVA technologies, which includes bytecode, can be by executing first class file
The external request that bytecode sends client is handled.
Wherein, when the load of the concentrating type system is smaller, the outside which directly sends client asks
It asks and is handled, which need not be transmitted to service server, so that the service server handles the external request,
The time that access server is consumed to service server forwarding external request is avoided, and avoids access server and receives industry
The time that server transmission response message of being engaged in consumes, in this way, reducing user end to server sends external request and the client
End receives the time interval between the response message that server is sent, that is, reduces the time that client receives response message, carry
The high response speed of website.And the external request that access server directly sends client is handled, and need not be incited somebody to action
The external request is transmitted to service server, and need not receive the response message of service server transmission, saves network
Resource.
Step 204：The external request that client is sent is transmitted to the business that the concentrating type system includes by access server
Server；
Specifically, access server load itself include for forward the second class file asked, pass through the of load
The external request that the client is sent is transmitted to the service server that the concentrating type system includes by two class files.
Wherein, after access server loads second class file, second class file is made to pass through procotol by the visitor
The external request that family end is sent is transmitted to the service server that the concentrating type system includes.
In order to avoid the server of processing external request is ceaselessly cut between access server and service server
It changes, and in order to avoid the influence that frequency fluctuation is brought, when second after access server loads second class file is default
Between in length, which no longer obtains the garbage reclamation frequency of the concentrating type system, directly passes through second class file
The external request of reception is transmitted to the service server that the concentrating type system includes.
Wherein, the second predetermined time period is more than the first predetermined time period, for example, the second predetermined time period can be
Ten minutes.
Wherein, when the quantity for the external request that access server receives simultaneously includes more than or equal to the concentrating type system
When the quantity of service server, the access server by the external request of reception be averagely allocated to that the concentrating type system includes it is every
A service server.
Wherein, access server and service server are all virtual machines in embodiments of the present invention, and access server and
All include the first class file and the second class file, the first class file on access server and service server on service server
External request can be handled, and the second class file on access server and service server can forward request.
Step 205：The service server that the concentrating type system includes receives the external request of access server transmission, and
The external request is handled, step 206 is executed；
Step 206：After the second predetermined time period, the rubbish that access server reacquires the concentrating type system returns
Receive frequency, return to step 202.
Wherein, in embodiments of the present invention, access server can load a virtual machine and adjust plug-in unit, virtual by this
Machine adjusts the method that plug-in unit executes above-mentioned processing external request.
In order to realize the optimization to network, for example the network is optimized when some numerical value reaches preset condition；
Or when some server in the concentrating type system breaks down, in order to no longer be carried out to external request by the server
Processing, technical staff may add some codes to realize in access server and/or service server.If to network
The number of optimization it is more or break down server it is more when, technical staff can repeatedly add code, lead to size of code
Expansion, and then increase the maintenance cost in later stage.And load a virtual machine in embodiments of the present invention and adjust plug-in unit, work as appearance
It is more when occurring by loading a corresponding virtual machine plug-in unit for meeting condition when primary network optimization or server failure
When the secondary network optimization or server failure, the virtual machine plug-in unit of load cannot be met the requirements, and can be unloaded the plug-in unit at this time, be added
Carry another plug-in unit for meeting condition.Due to load another meet the size of code in the plug-in unit of condition can be far smaller than multiple
The quantity of the code of addition, so being asked by loading virtual machine adjusting plug-in unit and adjusting plug-in unit processing outside by the virtual machine
The maintenance cost in later stage can be reduced by asking.
