Embodiment
In order to solve the problem utilizing existing ageing method important but infrequently accessed file can be cleared out of high-speed cache, the invention provides a kind of aging method of caching server content to retain important file.
Be described below in conjunction with the flow process of accompanying drawing to the inventive method embodiment.As shown in Figure 1, the flow process of the present embodiment comprises:
Step S101, judges whether the attribute of caching server high-speed cache file meets the condition of setting, if met, then enters step S102; Otherwise enter step S103.
Before burin-in process is carried out to the file in high-speed cache, can first judge file attribute.Judge whether the attribute of file meets the condition of setting, if met, then can think that this file is important, can exempt and carries out burin-in process to it and directly think that it is vital document, be retained in the high-speed cache of caching server; When judging that the attribute of file does not meet the condition of setting, then can carry out burin-in process to file.
The memory device as high-speed cache in the present embodiment can be internal memory, solid state hard disc, scsi (Smallcomputer system Interface small computer system interface) hard disk etc.
When imposing a condition, can be in the mode of the priority level of enactment document, namely grade setting being carried out to each file, like this can according to grade setting condition when imposing a condition.Such as, can using priority level for height be as imposing a condition.Therefore, more preferably, the attribute of the file in described high-speed cache is the priority level of file, then the priority level of the file in described high-speed cache reaches the condition that the rank preset is considered as meeting setting; Otherwise be the condition not meeting setting.Certainly, the setting of condition is without any restriction, and can do arbitrary restriction for file attribute, the name as file is called the condition of setting, then file name and the file that conforms to of imposing a condition are considered as meeting the condition of setting; Also can file size, function etc. as setting condition.For the file needing to reside at for a long time in high-speed cache, we impose a condition with regard to its attribute, and the file be saved to enable needs meets the condition of setting.
Step S102, is labeled as non-burin-in process file by the backup of file described in file described in high-speed cache and disk.
For the file being labeled as non-burin-in process, can exempt and burin-in process is carried out to it and is directly retained in caching server high-speed cache.During in order to ensure that caching server is restarted at every turn, file in caching server high-speed cache continues to remain in caching server high-speed cache, File lose when preventing caching server from restarting in high-speed cache, therefore more preferably, when restarting caching server at every turn, non-burin-in process file will be labeled as and be loaded in caching server high-speed cache from buffer memory server disk.Because the file stored in the caches also can leave backup on disk, when therefore each caching server is restarted, the file being labeled as non-burin-in process can be loaded in caching server high-speed cache from disk.When so just can ensure that each caching server is restarted, in high-speed cache, due file can continue to reside in high-speed cache, and can not lose because of restarting of caching server.
Step S103, performs burin-in process to file described in caching server high-speed cache.
Through step S101, a high-speed cache file judges that the result drawn is the condition not meeting setting, this file but may in judgement before, because meeting condition set at that time with non-aging mark, but this file has lost the necessity resided at for a long time in high-speed cache, needs to be added the ranks carrying out burin-in process.Therefore more preferably, if the attribute of caching server high-speed cache file does not meet the condition of setting, judge whether file described in high-speed cache has been labeled as non-burin-in process file, if it is cancel the non-burin-in process mark of file backup described in file described in high-speed cache and disk, and enter burin-in process unit; Otherwise, directly enter burin-in process unit.Imposing a condition but also with the file that non-burin-in process marks for not meeting, first should cancel its non-burin-in process mark, and equally also cancel the non-burin-in process mark of this file backup on disk, then burin-in process is carried out to it.Like this, when caching server is restarted, do not need it to reload from disk in high-speed cache yet.
The step of burin-in process is carried out as shown in Figure 2 to file, comprising:
Step S1031, utilizes the frequency of utilization of least recently used Lru algorithm to file described in high-speed cache process and obtain result.
The file carrying out burin-in process is needed to judgement, first utilizes the frequency of utilization of Lru algorithm to file to process, obtain the frequency of utilization of file and the last time used.
Step S1032, judges whether the result obtained meets cleared condition, if met, then by the unloading of file described in high-speed cache in disk, and from high-speed cache, this file to be removed.
Step S1032 then judges whether the result obtained meets the condition be eliminated, and to judge whether file should be moved out of rear removing, or needs to continue to retain.Lru algorithm mainly finds out and is not used for a long time, or frequency of utilization is little and do not need the file that stays in high-speed cache, these files are shifted out high-speed cache to vacate cache memory space, make other important, need the file that can be quickly accessed to move into high-speed cache.For the file needing to be moved out of, directly shifted out, for high-speed cache vacates storage space.And for the file confirming to need to continue to remain in high-speed cache after Lru algorithm calculates, then continue to remain, but in the process of restarting, it can not be loaded in high-speed cache from disk.
Technical scheme in the present embodiment is before carrying out burin-in process to file, first attribute is met the file imposed a condition and directly retains in the caches, and does not meet to attribute the file imposed a condition and carry out burin-in process.Attribute is not met to the file imposed a condition, first utilize lru algorithm to carry out treatment and analysis to it, then the result for the treatment of and analysis is met the file that setting is removed, shift out from high-speed cache and remove from high-speed cache.Adopt the technology that the present embodiment provides, can by important, need fast access but the low file of access frequency is retained in caching server high-speed cache, to ensure can conduct interviews to these files fast when these files accessed by needs, and do not need again to search in degaussing dish.Can flexible configuration in the setting of the attribute conditions of the file preserved, to meet the different needs, the file needed is resided in the high-speed cache of caching server.
Be described specific embodiments of the invention below in conjunction with Fig. 3, the flow process of specific embodiment is:
Step S301, judges whether the attribute of caching server high-speed cache file meets the condition of setting, if met, then enters step S302; Otherwise enter step S303.
Imposing a condition in this step can be arranged as required flexibly.Actual needs fast file is retained in the high-speed cache of caching server by setting model, makes, when needs use these files, to have access to fast in the high-speed cache of caching server.Described condition can set flexibly, sets relevant condition according to different demands, resides in high-speed cache to make the file needed.
Step S302, is labeled as non-burin-in process file by file backup described in file described in high-speed cache and disk.
The file being labeled as non-burin-in process can reside in high-speed cache, and can not cause being moved out of high-speed cache after Lru algorithm because of not using for a long time or seldom using.
Step S303, whether be be labeled as non-burin-in process file, if yes then enter step S304, otherwise enter step S306 if judging that file attribute does not meet the file imposed a condition.
Do not meet for attribute the file imposed a condition and likely have two kinds, a kind of is not with the file that non-burin-in process marks, then directly can carry out burin-in process to it; Also have a kind of be meet before impose a condition and the file that marks with non-burin-in process, then need first the burin-in process mark of the file in high-speed cache and the backup of disk file all to be cancelled, like this when restarting caching server, then it also can not be loaded in high-speed cache from disk.
Step S304, cancels the non-burin-in process mark of file backup described in file described in high-speed cache and disk.
Step S305, utilizes the frequency of utilization of least recently used Lru algorithm to file described in high-speed cache process and obtain result.
Step S306, judges whether the result obtained meets cleared condition, if met, then enters step S206.
Step S305 and step S306 first obtains to need the file carrying out burin-in process to utilize its service condition of Lru algorithm evaluation, and the file then service condition being met cleared condition shifts out high-speed cache.
Step S307, by the unloading of file described in high-speed cache in disk, and removes described file from high-speed cache.
Namely carry out burin-in process to file is first calculate the frequency of utilization of file, then will meet the file of cleared condition, and namely frequency of utilization is lower than a certain degree or do not used the file reaching the regular hour to shift out in the high-speed cache of caching server.Also can continue to reside in high-speed cache for the file not meeting cleared condition.
Namely the file being marked as non-burin-in process is meet the file imposed a condition, namely thought important, needing can the file of fast access, in order to ensure that the file being marked as non-burin-in process resides in high-speed cache always, can not lose because of restarting of caching server, more preferably, when restarting caching server at every turn, non-burin-in process file will be labeled as and be loaded in caching server high-speed cache from buffer memory server disk.Such can guarantee need the file resided in high-speed cache to be also stored in high-speed cache after each caching server is restarted at every turn, and can not restart loss because of caching server.
The attribute of the technical scheme that the present embodiment provides to the file in high-speed cache judges, judge that attribute meets the file imposed a condition and can be resided in high-speed cache, and the file ineligible to attribute, can first cancel file with non-burin-in process mark, again burin-in process is carried out to it, or directly burin-in process is carried out to the file marked without non-burin-in process.Adopt technical scheme provided by the invention can by important, need the file be quickly accessed to reside in high-speed cache, and need retained but do not need afterwards by the file retained for judging before, its non-burin-in process mark can be cancelled, and do not meet together with the file that imposes a condition with other attributes and be performed burin-in process, for high-speed cache vacating space store important, need the file that is quickly accessed.
About the technological means of condition setting in the aging method of caching server content provided by the invention, also can apply in ACL (Access Control List (ACL)).Limit the condition of access control, conducting interviews to the satisfied file imposed a condition or limiting conducts interviews to meeting the file imposed a condition.
Present invention also offers the caching server corresponding with method.Below in conjunction with Fig. 3, the caching server structure of embodiments of the invention is described.
