Embodiment 2
For the service efficiency that improves the client machine internal memory and user's experience, the embodiment of the invention provides a kind of method of adjusting internal memory, size by the adaptive adjustment working procedure of software program self, make the client machine internal memory rationally to use, be example with P2P software in the embodiment of the invention wherein, referring to Fig. 2, concrete workflow synoptic diagram is as follows:
201: client machine starts, and the P2P software program starts in client machine;
Wherein, after client machine starts, a plurality of software program operations are arranged simultaneously in client machine generally when the P2P software program starts in client machine, take the internal memory of client machine jointly;
When P2P software has just started operation in client machine, can set by minimum EMS memory occupation machine internal memory; The minimum internal memory here refers to P2P software can normally move needed minimum memory headroom; For example: certain P2P software program needs 200M when normally moving, and saves as 100M in the minimum, represents that this P2P software has only at internal memory under the situation of 100M, just can move.Wherein, for the setting of the minimum internal memory of P2P software, be provided with flexibly as the case may be, the embodiment of the invention does not limit this.
202:P2P software obtains the initial committed memory of current this P2P software;
Wherein, P2P software obtains the initial committed memory of current this P2P software, specifically comprises following dual mode:
(1) obtains initial committed memory default in P2P software;
Wherein, can set in advance initial committed memory in P2P software, when this P2P software moved in client machine, P2P software obtained this initial committed memory; For example: initial committed memory default in the P2P software is 250M, will obtain this initial committed memory when then P2P software moves in client machine, and is taking the machine internal memory according to this initial committed memory.Wherein, initial committed memory default in the P2P software can be revised flexibly according to actual conditions, such as when the P2P software upgrading or when increasing new function, and the size of the initial committed memory value of raising that can be suitable.
(2) from configuration server, obtain the initial committed memory of this P2P software;
Wherein, configuration server needs the initial committed memory of P2P software is configured in advance, when configuration, can the frequency of utilization of this P2P software and the various factorss such as busy extent of user's recent work be configured, referring to table 1 according to size, the minimum internal memory of this P2P software, the size of client machine internal memory, the user of this P2P software.
Table 1
| P2P software | The software size | Minimum internal memory | The machine internal memory | Frequency of utilization (inferior/day) | Busy extent | Initial committed memory |
| P2P software 1 | 200M | 80M | 1G | 5 | Busy | 80M |
| P2P software 2 | 150M | 70M | 1G | 1 | Be not in a hurry | 100M |
| P2P software 3 | 120M | 50M | 2G | 0.5 | Busy | 120M |
In the table 1, the software size of P2P software 1 is 200M, save as 80M in the minimum, save as 1G in the machine, frequency of utilization is one day 5 times, illustrates that the user often uses this P2P software, but because user's recent work is busier, take bigger machine internal memory, so configuration server has only been given this P2P software arrangements initial committed memory of 80M; Wherein, configuration server is greater than the minimum internal memory that equals this P2P software when giving the initial committed memory of software arrangements, because the minimum internal memory of P2P software is the condition that guarantees this P2P software operate as normal; If the initial committed memory of configuration is less than the minimum internal memory of this P2P software, then this P2P software can't start operation.
The software size of P2P software 2 is 150M, save as 70M in the minimum, save as 1G in the machine, frequency of utilization is one day 1 time, illustrate that the user more often uses this P2P software, and user's recent work is not in a hurry, but owing to save as 1G in the machine, may move a plurality of softwares in the machine internal memory, so configuration server has been given this P2P software arrangements initial committed memory of 100M.
The software size of P2P software 3 is 120M, save as 50M in the minimum, save as 2G in the machine, frequency of utilization is one day 0.5 time, illustrate that the user does not often use this P2P software, user's recent work is also busier, but owing to save as 2G in the machine, enough free memory working procedures are arranged, so configuration server has been given this P2P software arrangements initial committed memory of 120M.
Configuration server is stored in the configuration server after giving the initial committed memory of P2P software arrangements; The initial committed memory of in store a plurality of softwares in the configuration server when software moves, obtains corresponding initial committed memory in configuration server in client machine.
Configuration server can be the server that is specifically designed to the initial committed memory of configuration, also can be that other arbitraryly have a server that can dispose initial EMS memory occupation function.
In the step 202, P2P software also can not need to obtain the initial committed memory of current this P2P software, but takies the machine internal memory according to the initial committed memory of acquiescence, and such as giving tacit consent to all software when starting operation, initial committed memory is 100M; Wherein, be provided with P2P software the initial committed memory of acquiescence can be client machine when promptly all software programs in the operation of this client start initial committed memories all be 100M, also can be provided with by any other server, generally will consider the minimum internal memory of the software that is moved when being provided with, to guarantee the normal startup of software.
203:P2P software takies the operation of client machine internal memory according to the initial committed memory that obtains;
Wherein, P2P software takies the operation of client machine internal memory according to the initial committed memory of this P2P software that obtains in the step 202.
If the client machine internal memory too little minimum internal memory that can not satisfy P2P software of free memory at this moment, P2P software can't normally move, can call virtual memory and move this P2P software, increase if detect the free memory of client machine in follow-up process, this P2P software reruns.
Through step 201-203, finished the startup operational process of P2P software, after the normal operation of P2P software, the operating position that also needs continuous detection machine internal memory, so that can adjust the size of P2P running software program dynamically, and then rational and effective utilizes the machine internal memory, and concrete dynamic adjustment process is referring to step 204-207.
Behind the 204:P2P running software, regularly detect the free memory of active client machine;
Wherein, after the committed memory operation, according to the default time interval, timing is according to the size to free memory in the active client machine in client machine for the initial committed memory that P2P software basis is obtained.Wherein, for the setting in the time interval, can set flexibly according to actual conditions, the embodiment of the invention does not limit this.
205:P2P software judges that whether free memory is less than preset threshold, if carry out 206 in the active client machine; Otherwise, carry out 207.
Wherein, free memory in the client machine is preestablished a threshold value; If free memory is less than this threshold value in the active client machine, low free memory in the active client machine is described, influenced the operation of each software in the client machine, need to increase free memory; If free memory is more than or equal to this threshold value in the active client machine, illustrate that free memory is bigger in the active client machine, there is unnecessary internal memory to use, a part of free memory can be used to move P2P software.Wherein, the threshold value of free memory is set flexibly according to the actual conditions of client machine, such as the free memory that can set client machine is 30%, is 30% of client machine memory size.If, be lower than this value, then need P2P software to discharge a part of internal memory, if be higher than this value, the free memory residue of client machine is described, can be used for the P2P running software this moment with a part of free memory.
206:P2P software release portion internal memory is given client machine, as the free memory of client machine;
Wherein, P2P software judges that free memory is known low free memory in the active client machine less than preset threshold value in the active client machine, and P2P software internal memory that release portion is being moved then is to increase free memory in the client machine.
The internal memory that must guarantee self to use behind the internal memory that P2P software is discharged is more than or equal to minimum internal memory, to guarantee the normal operation of P2P software.For example: current P2P software detection free memory in the active client machine is 100M, and the threshold value of free memory is 200M in the client machine, free memory also needs 100M in the client machine, save as 150M in the current use of P2P software, and save as 100M in the minimum, then P2P software can only discharge the internal memory of 50M at most to client machine.If P2P software releasable internal memory need greater than client machine free memory the time, then discharge the free memory that client machine needs, and need not whole releases; For example: current P2P software detection free memory in the active client machine is 100M, and the threshold value of free memory is 200M in the client machine, free memory also needs 100M in the client machine, save as 300M in the current use of P2P software, and save as 100M in the minimum, then the P2P software internal memory that can discharge 200M is at most given client machine, but this moment, client machine only needed the free memory of 100M, and then P2P software only need discharge 100M and gets final product.
207:P2P software reconfigures the new committed memory of P2P software, and according to new committed memory, takies the internal memory of client machine.
If judge that free memory can reconfigure new committed memory by configuration server more than or equal to preset threshold in the active client machine, P2P software takies the internal memory of client machine according to new committed memory.
Wherein, when the new committed memory of configuration, active client machine free memory and free memory preset threshold are asked poor, obtain configurable free memory; To configurable free memory and the current committed memory summation of P2P software, obtain new committed memory; P2P software takies the internal memory of client machine according to new committed memory.
For example: active client machine free memory is 300M, and client machine free memory preset threshold is 200M, and then configurable free memory is 100M; And P2P software current taking in save as 150M, then new committed memory is 350M; P2P software will take the internal memory of client machine according to 350M later.
After step 207 executes, after a time interval, continue execution in step 204-207, by execution in step 204-207 repeatedly, realize the purpose of the memory size that dynamic adjustment software takies in client machine, reasonably used the internal memory of client machine.
Above-mentioned steps 204-207 by the operating position of one-time detection machine internal memory, realized adjusting dynamically the size of P2P running software program, and then rational and effective is utilized the machine internal memory.
Be example with P2P software in the embodiment of the invention, the method that the embodiment of the invention provides also is applicable to other any software that moves in client machine, realize the program size that the dynamic P2P of adjustment software moves in client machine, realized reasonable utilization, improved service efficiency the client machine internal memory.
The method that provides in the embodiment of the invention is specially adapted to P2P software, because P2P software has a lot of shared data, need constantly to download the data of other clients, the data that also need simultaneously constantly to upload self are given other clients, if rationally adjust internal memory, can so that client machine will be in internal memory the data download of buffer memory, be uploaded to the client that other need these data simultaneously; Perhaps read a given data from hard disk, being uploaded to a plurality of other simultaneously needs the client of these data at every turn, thereby reduces the reading times of hard disk, improves travelling speed.
The method that the embodiment of the invention provides, by regularly detecting the internal memory operating position in the client machine, the memory size that dynamic adjustment software takies in client machine, reasonably used the internal memory of client machine, accelerate the travelling speed of client machine, improved user's experience.
