The embodiment of the invention further discloses a device for recovering the high speed cache data.

Description
Technical Field
The present invention relates to the field of computer storage technologies, and in particular, to a method and an apparatus for recovering cache data.
Background
A cache is a block of memory space between a processor and memory that is smaller than the memory, and the processor accesses the cache much faster than the processor accesses the memory.
When the processor receives an access request of a file, the processor firstly accesses the memory and opens and reads the file. Due to the slow access speed of the memory, if the files are stored in the cache, the processing efficiency is greatly improved, and the access time of the files is shortened. The cache capacity of the system is limited and it is not possible to store all files in the cache.
At present, the access frequency of files on a record memory is adopted, and files with frequent partial access are loaded into a cache periodically or aperiodically, and files stored in the cache are updated at the same time, so that the defect of limited cache capacity is solved.
For example, the color ring back tone of the operator or the server device of the customer service bureau point is shown in fig. 1.
Fig. 1 is a block diagram of a color ring back tone or customer service bureau server device of an operator, which includes a manager 101, a file server 102, a plurality of signaling processors 104, a plurality of service processors 106, and a plurality of resource processors 108. Wherein,
the manager 101 is used for maintaining and monitoring files, interacting with a user interface and the like;
the file server 102 is used for storing all files for the resource processor 108 to access and read;
the signaling processor 104 is used for exchanging and processing signaling with other devices;
the service processor 106 is used for providing services;
the resource handler 108 is used for reading and calling files.
Each signaling processor 104, service processor 106 and resource processor 108 in the server device are identified by a number that is independent and unique within the device, and each processor has an internal communication mechanism for information interaction.
FIG. 2 is a block diagram of the resource processor 108. As shown in FIG. 2, the resource handler includes a control module 201, a file call module 202, an IO module 203, and a cache 204.
The control module 201 is configured to receive and process an operation request sent by the manager 101 or other processors, control the relevant modules to complete corresponding operations, and return a response and a result of execution of the operation request to the manager 101 or other processors.
The file calling module 202 is configured to process the file read by the IO module 203 according to the control of the control module 201.
The IO module 203 is configured to complete interaction between the control module 201 and the cache 204 and between the control module 201 and the file server 205, including operations of constructing the cache 204, reading a data file from the cache 204 and the file server 205, and the like.
The cache 204 is used for storing frequently accessed files on the file server, and is used for the IO module 203 to perform fast reading or calling.
For example, in a ring back tone or a customer service bureau of an operator, the ring tone file is typically stored on the file server 205. When the resource processor needs to perform voice playback operation, the control module 201 controls the IO module 203 to access the file server 205, open and read the ring tone file, and then the file calling module 202 performs playback. In order to increase the speed of file access and reading, the resource processor may create a cache 204 in memory, and the resource processor loads frequently used ring tone files into the cache 204 periodically or aperiodically according to the file access frequency, and updates the ring tone files stored in the cache 204. When the file calling module 202 accesses these files loaded in the cache 204, it does not need to access the file server 205, but directly plays the ring tone file in the cache 204. Since the access frequency of the file is variable, the control module 201 needs to eliminate and update the file in the cache 204 according to a certain mechanism, delete the file with the lower access frequency from the cache 204, and store the new file with the higher access frequency in the cache 204.
Since the cache 204 is actually part of the memory, and the access frequency information of the file is also stored in the memory, the cache 204 will lose all the stored data whenever the resource processor is restarted, and the data can only be rebuilt.
There are two ways to establish the data in the cache 204:
first, the resource handler is restarted, and after a period of time, the control module 201 instructs the IO module 203 to select the file accessed on the file server 205 to be loaded into the cache 204 during the period of time. Thereafter, the control module 201 instructs the IO module 203 to evict and update the data in the cache 204 according to a certain mechanism.
Second, the resource handler is restarted, and each time a file on the file server 205 is accessed, the control module 201 instructs the IO module 203 to load the accessed file into the cache 204. After the cache 204 is full, the control module 201 instructs the IO module 203 to evict and update the data in the cache 204 according to a certain mechanism.
In implementing the present invention, the inventors have discovered that the selection of files stored on a cache is important because the space of the cache is much less than the storage space on the file server. Each resource handler in the server device is relatively independent, and for each resource handler, after each reboot, a relatively long and relatively large number of file accesses are required before the files stored in the cache are relatively stable, and the cache hit rate (the number of times a file is read from the cache as a proportion of the total number of times the resource handler accesses files from the file server and the cache) is relatively high.
Taking the color ring office as an example, in a first mode, under the condition that the proportion of the storage space of the cache and the storage space of the file server is 1: 10000, after the initial construction of the switch environment, the hit rate of the cache is increased from initial 0% to about 95%, and about 30 days are needed; and by adopting the second mode, the cache hit rate is increased to about 95% in the same condition, which requires about 45 days.
That is, in both the first and second modes, the data in the cache is rebuilt after a long period of time and multiple file accesses, and a longer period of time is needed to keep the cache data relatively stable.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples.
The embodiment of the invention can recover the files in the cache in a short time by recovering the files in the cache by using the backup data, so that the data of the cache does not need to be re-created, and the hit rate of the cache is favorably improved in a short time.
Example one
The technical scheme of the embodiment comprises two parts of cache backup and reconstruction.
The backup of the cache refers to exporting and saving the file information of the files in the cache in the backup data.
And the reconstruction of the cache refers to that the resource processor reads the backup data and reconstructs the cache according to the file information in the backup data.
The file information saved in the backup data may be an attribute of the file or a complete file, where the file attribute is a file name of the file and/or a file path that characterizes a storage location of the file on the file server.
The cache backup can be implemented in four ways:
the first way is to store the contents of the cache as a separate file, and only the file attributes of each file stored in the cache, such as the file path and/or file name at the file server, are listed in the file. This approach is suitable for situations where the file path in the file server is not constantly changing.
The second way is to store the cached content as a separate file, where all the files in the cache and their organization structure, i.e. the complete content of the cache, are stored. This approach is applicable to situations where the file path in the file server is not fixed.
A third way is to store the contents of the cache in a directory, where each individual file in the directory or a sub-directory thereof is a complete file stored in the cache.
A fourth way is to store the content in the cache in a directory, where the files in this directory or a sub-directory thereof list the file attributes of each file stored in the cache, such as the file path and/or the file name in the file server, etc.
The embodiment still uses the customer service bureau point device of the operator as an example to describe the implementation manner of the present invention.
FIG. 3 is a diagram illustrating the structure of a resource processor according to the present embodiment.
The resource handler of the present embodiment includes: a control module 301, a file call module 302, an IO module 303, and a cache 304.
The IO module 303 in this embodiment may perform information interaction with not only the file server 305 but also the storage 306.
The memory 306 is used to store files in the cache. The memory 306 may be a storage device separate from the file server, a storage device of the file server, or a storage device inside the resource processor, such as FLASH or RAM.
The cache data recovery apparatus of this embodiment can recover a file in a cache, and mainly includes the following functional units:
a backup data generation unit configured to generate backup data for recording information of the files stored in the cache;
a backup data writing unit for writing the backup data into a memory;
a backup data reading unit for reading backup data for recording file information of the files stored in the cache from the memory;
and the file recovery unit is used for writing the files corresponding to the file information in the backup data into a cache.
The function of the cache data recovery apparatus is performed by the IO module 303 as a preferred embodiment of the present invention, but it should be understood by those skilled in the art that the cache data recovery apparatus may be a separate apparatus or exist in other devices or modules or perform its function by other devices or components.
Fig. 4 is a flowchart of cache backup in this embodiment. As shown in fig. 4, the backup process of the cache includes the following steps.
Step 401: the backup of the cache is started, i.e. a backup request for backing up the cache data is sent to the control module. The backup request can be sent to the control module by the manager through manual starting of a user, or can be sent to the control module by the manager through timing starting.
Step 402: after receiving the backup request, the control module sets the state of the cache as unavailable, so as to avoid the influence of the operation of reading and updating the cache on the backup process.
Step 403: the control module instructs the IO module to initiate a backup of the cache.
Step 404: and after receiving a backup instruction for starting the cache, the IO module creates backup data on the memory, wherein the backup data is used for recording file information of files stored in the cache. The backup data may have different forms, such as files or directories, according to the selected backup mode.
For example, when the IO module uses a method of backing up a complete file, each file in the cache is read in sequence, and each read file is written into the backup data in sequence;
when the IO module adopts a mode of backing up file attributes, reading each file in the cache in sequence to obtain the attributes of each file, and writing the attributes of each file, such as the file name and/or the file path representing the storage position of the file on the file server, into the backup data in sequence.
In order to prevent backup data of multiple similar devices at different times from interfering with each other, the backup data needs to be identified by the unique device identifier of the device performing backup at the customer service bureau point and the current time of writing the backup data.
Step 406: and the IO module determines a backup mode according to the configuration, reads the first file in the cache, and extracts the file information of the file for backup.
Depending on the backup method, the backed-up file information may be a list of file attributes in the cache, such as a list of file paths and file names, or all files in the cache and their organization structure. The backup data may be an independent file of a file attribute list in the cache, an independent file of a complete file and structure in the cache, a directory of a complete file and structure in the cache, or a directory of file attributes of each file in the cache.
For an independent file only storing a file attribute list in a cache, the IO module only needs to sequentially write file attributes of each file, such as a file path and/or a file name of each file, into backup data;
for storing the complete files and the independent files with the structures in the cache, the IO module needs to read each file in the cache in sequence and write the files into the backup data in sequence;
for the forms of storing complete files and structural directories in the cache respectively, the IO module is to store the files in the cache into the directories of the backup data respectively;
for the directory format that respectively stores the file attributes of the files in the cache, the IO module is to respectively store the file attributes of each file in the cache, such as the file path and/or the file name in the file server, into the directory of the backup data.
To distinguish backup data for different resource processors at different times, the naming of the backup data may be in the form: "resource processor number + backup time", for example, the backup data generated by the resource manager with number 252 at 11 on 2007 at 14.07/2007, the name may be
"252 _ 200707140211". If only the file name and path of each file on the file server are saved in the backup data, the content in the backup data may be in the form of:
“y:\playfile\yesterdayoncemore.wav；
y:\playfile\whenyoubelieve.wav；
y:\playfile\prodeoffly.wav；”
since the cache is set as unavailable during the backup process, it may be selected to initiate the backup of the cache at a time of least traffic, e.g., early in the morning, in order to minimize the impact of the backup on the development of normal traffic.
Step 408: and the IO module writes the file information of the first file into the backup data created on the memory.
Step 410: the IO module reads the second file in the cache and extracts the information of the file to be backed up.
Step 412: and the IO module writes the file information of the second file into the backup data created on the memory.
Step 414: and the IO module sequentially reads the files in the cache until the last file in the cache and extracts the information of the files needing to be backed up.
Step 416: and the IO module writes the file information of the last file into the backup data created on the memory.
Step 418: and the IO module writes the current backup time information into the backup data.
Step 419: the IO module returns the cache backup result to the control module, namely whether the backup is successful or not.
Step 420: and the control module receives the cache backup result of the IO module and sets the cache function to be available.
Step 422: the control module returns the cache backup result to the manager, namely whether the backup is successful or not.
When the resource processor is restarted, the reconfiguration process of the cache can be started manually or automatically.
Fig. 5 is a flowchart of cache reconstruction in the present embodiment, which includes the following steps.
Step 501: and starting the reconstruction of the cache, namely sending a reconstruction request for reconstructing cache data to the control module. The reconfiguration request may trigger the control module by the resource manager to perform reconfiguration of the cache when the resource processor is restarted.
Step 502: the control module sets the state of the cache as unavailable after receiving the cache reconfiguration request.
Step 504: the control module instructs the IO module to initiate reconfiguration of the cache.
Step 505: and the IO module reads the backup data information in the memory.
Step 506: the IO module selects backup data for cache reconstruction from the backup data. Preferably, the IO module selects a backup data of the resource handler that is the latest, for example, a backup data of which creation time is the latest may be selected from the selectable backup data.
Step 508: and the IO module reads the first file information in the selected backup data.
The file information may be the attribute of the file or the complete file, and the backup data may be in the form of an independent file or a directory, depending on the backup method.
When the IO module judges that the backup data is an independent file or a directory containing complete files, sequentially reading each file corresponding to each file information in the backup data, and sequentially writing each read file into the cache;
when the IO module judges that the backup data is an independent file or a directory containing file attributes of the file, sequentially reading the file attributes in the backup data, such as the recorded file name and the recorded file path, accessing a file server for storing the file according to the file name and/or the file path, sequentially reading the file corresponding to the file attributes from the file server, and writing the file into the cache.
For individual files or directories that only hold a list of file attributes in the cache, step 509 is performed;
step 510 is performed for individual files that hold all files and structures in the cache, or each file in the cache is held in the form of a directory.
Step 509: and the IO module accesses the file server and reads the corresponding file according to the file information. If no corresponding file is found, go to step 512; otherwise, execution continues at step 510.
Step 510: the IO module writes the first file into the cache.
Step 512: and the IO module reads the second file information. If only the file path and/or file name is saved, step 513 is performed, otherwise step 514 is performed.
Step 513: and the IO module accesses the file server and reads the corresponding file according to the file path and/or the file name. If no corresponding file is found, go to step 516; otherwise, execution continues with step 514.
Step 514: the IO module writes the second file to the cache.
Step 516: and the IO module sequentially reads the file information in the cache until the last file information in the cache.
517: the backup data only stores the path and the file name of the file, the IO module accesses the file server, and reads the corresponding file according to the file path and/or the file name. If no corresponding file is found, go to step 519; otherwise, execution continues with step 518.
Step 518: the IO module writes the last file into the cache.
Step 519: and the IO module returns the result of cache reconstruction to the control module.
Step 520: and the control module receives a cache reconstruction result returned by the IO module and sets the state of the cache to be available.
Step 522: the control module returns the results of the cache reconstruction.
Through the above steps, the cache is restored to the state of the last backup, where the files were the most frequently accessed files from the last backup.
In addition, after a certain resource handler is restarted, if the file backed up by the resource handler is not found, the backup files of other resource handlers can be selected to be loaded.
When the technical scheme of the embodiment is applied to the color ring office of the operator, the color ring file with the most times of access to the office can be backed up, and when the resource processor is restarted, the data in the cache can be quickly recovered by using the backup file; when the technical scheme of the embodiment is applied, the server providing the video service can back up the video files which are watched or downloaded most, and the like.
For local sites that are already functioning properly, each resource processor may periodically or manually build its cached backup data. When a resource handler is restarted, backup data created by the resource handler or created by other resource handlers in the local site can be loaded immediately.
For the newly established local point, because the hit rate of the cache in the resource processor needs a long time to be stabilized at a higher level just after the local point starts to operate, and the practicability of the backup data of the cache is not high, the cache backup data of other local points can be directly used, or the backup data of popular files can be manually created according to the current popular information to construct the cache of the new local point, so that the hit rate of the cache of the new local point is improved.
For some similar local points in application, such as intelligent peripheral local points of an intelligent network, because the resources are relatively fixed, cache backup data can be manually generated in advance for the local points to be directly loaded into the cache, so that the hit rate of the cache of the local points can be greatly increased, and the construction time of the cache can be obviously reduced.
It can be seen from the above embodiments that the method for recovering cache data of the present invention can recover data in a cache when needed, and can rapidly improve the hit rate of the cache.
The device for recovering the cache data can recover the data in the cache of the device when needed and can quickly improve the hit rate of the cache.
In summary, the above are only some examples of the present invention, and are not intended to limit the scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
