In writing the second configuration file, ENUM-DNS servers timing detect first configuration file with it is described
With the presence or absence of different file identifications in second configuration file, if first configuration file is matched somebody with somebody with described second
Put and exist in file different file identifications, then illustrate in ENUM-DNS servers and distributed cache system
Data it is inconsistent, now, ENUM-DNS servers by the corresponding file of different file identifications preserve to
In the distributed cache system, due to need not be by ENUM-DNS servers and distributed cache system
In data file contrasted, greatly reduce detection ENUM-DNS servers and distributed caching system
Data in the system whether consistent time, safeguard that ENUM-DNS servers are slow with distributed so as to improve
The efficiency of the data consistency in deposit system, improves the reliability of ENUM-DNS servers.
Further, data managing method second embodiment of the present invention is proposed based on first embodiment, at this
In embodiment, step S10 includes：With the data file corresponding file identification write described the
In one configuration file, to update first configuration file in preserve file identification；
Step S20 includes：With preserving the corresponding file identification write of the successfully data file the
In two configuration files, to update second configuration file in preserve file identification；Wherein when a certain number
When not preserving successful according to file, the data file is persistently repeatedly written until writing successfully, or lose in write
Report and alarm when losing；
Step S30 includes：Detect the file identification and described the preserved in first configuration file
Whether the file identification preserved in two configuration files is consistent；The file preserved in first configuration file
When identifying inconsistent with the file identification preserved in second configuration file, by first configuration file
The files-designated of difference between the file identification preserved in the file identification of middle preservation and second configuration file
Know corresponding data file to write into the distributed cache system.
In the present embodiment, the file identification is the text added to the data file according to reception order
Part is numbered, the corresponding file identification write described first of the data file that ENUM-DNS servers are generated
In configuration file preserve file identification, to update first configuration file in preserve file identification.
For example, when ENUM-DNS servers generate data file for the first time, first data for generating are set
The corresponding file identification of file is 1, and the corresponding file identification 1 of the data file of generation is write into the first configuration
In file and preserve.When ENUM-DNS servers second generate data file, for generating is set
The corresponding file identification of two data files is 2, and the file identification 2 is write in the first configuration file,
Replace preserve file identification 1, to update first configuration file in preserve file identification.When
When ENUM-DNS servers third time generates data file, the 3rd data file correspondence for generating is set
File identification be 3, the file identification 3 is write in the first configuration file, replace preserve files-designated
Know 2.Go down according to this, when ENUM-DNS servers generate file every time, update first configuration
The file identification preserved in file.
ENUM-DNS servers successfully by generate first data file write to distributed caching system
When in system, the corresponding file identification 1 of be successfully written first data file is write into the second configuration file
In and preserve.ENUM-DNS servers are successfully preserving second data file for generating to distributed
When in caching system, the corresponding file identification 2 of second data file for successfully preserving is write into described the
In two configuration files, replace preserve file identification 1, to update second configuration file in preserve text
Part is identified.ENUM-DNS servers are successfully writing the 3rd data file for generating to distributed slow
When in deposit system, the corresponding file identification 3 of the be successfully written the 3rd data file is write into described second
In configuration file, the file identification 2 for preserving is replaced.Go down according to this, it is each in ENUM-DNS servers
When successfully preserving data file into distributed cache system, update what is preserved in second configuration file
File identification.When a certain data file does not preserve successful, other data files having not been written to of generation
Do not write, be persistently repeatedly written the data file until writing successfully, or reported in write failure
Alarm.
ENUM-DNS servers timing detect in first configuration file preserve file identification with it is described
Whether the file identification preserved in the second configuration file is consistent.The text preserved in first configuration file
When part identifies inconsistent with the file identification preserved in second configuration file, by the described second configuration text
The file of difference between the file identification preserved in the file identification preserved in part and first configuration file
Identify corresponding data file to write into the distributed cache system.For example, if first configuration
The file identification preserved in file is 10, and the file identification preserved in second configuration file is 5, then
The file identification preserved in the file identification and second configuration file that preserve in first configuration file
It is inconsistent, ENUM-DNS servers by second configuration file preserve file identification 5 with it is described
The corresponding data file of file identification of difference between the file identification 10 preserved in first configuration file,
I.e. file identification 6 is preserved to the distributed caching system to 10 corresponding 5 data files of file identification
In system.
The scheme that the present embodiment is provided, ENUM-DNS servers when data file is generated every time, according to
The file identification preserved in the first configuration file of the corresponding file identification renewal of data file, and inciting somebody to action
When the data file for generating is successfully written into distributed cache system, according to the data file pair
The file identification answered updates the file identification preserved in the second configuration file, the timing of ENUM-DNS servers
Detect whether first configuration file is consistent with the file identification preserved in second configuration file, if
First configuration file is inconsistent with the file identification of preservation in second configuration file, then illustrate
ENUM-DNS servers are inconsistent with the data in distributed cache system, now, ENUM-DNS
Server by second configuration file preserve file identification and first configuration file in preserve
The corresponding data file of the file identification of difference is preserved to the distributed cache system between file identification
In, therefore, need to only contrast the files-designated of first configuration file and preservation in second configuration file
Know, further reduce data in detection ENUM-DNS servers and distributed cache system whether
The time of cause, so as to further increase the reliability of ENUM-DNS servers.
Further, as shown in Fig. 2 proposing data of the present invention based on first embodiment or second embodiment
Management method 3rd embodiment, in the present embodiment, the data managing method also includes step：
Step S40, every the 3rd preset duration, sends detection message every into the distributed cache system
The corresponding node of individual pre-set space, and detect whether to receive the corresponding node feeding back of each pre-set space
Response message；
Step S50, when the response message of the corresponding node feeding back of a certain pre-set space is not received, judges
The corresponding node of the pre-set space is abnormal nodes；
Step S60, counts the number of abnormal nodes in the distributed cache system, if the abnormal nodes
Number be more than predetermined number threshold value, then to operational system send warning message, simultaneously close off receiving data
Function, new data file is not regenerated at interval of the first preset duration, until system recovers normal.
In the present embodiment, the corresponding default sky of each node in the distributed cache system is pre-set
Between, and a special space is set, for example, the special space is set into No. 0 space, described No. 0
Space is used for after the data genaration file in ENUM-DNS servers by subscription and unsubscription, preserves
ENUM-DNS servers generate file, and by preserve file equally loaded to other each default sky
Between corresponding node, so as to ensure that each node stores in a balanced way and inquire about data.The pre-set space with
Node is corresponded, namely ensure that each node loads completely a search space.
During ENUM-DNS server initiations, respectively a fixed record is write to each pre-set space,
The corresponding fixation of ENUM-DNS server initiations that is recorded as of the fixation is recorded, concrete form here
It is not restricted.When record is repeatedly written, if the key values of the record being repeatedly written with it is front once
The key values of the record of write are the same, then the record of write-once before the record being repeatedly written is covered.
When write failure, then ENUM-DNS startup of server is not allowed, ENUM-DNS servers are initial
Change failure；When writing successfully, ENUM-DNS server initiation successes.When ENUM-DNS clothes
Business device initialization success after, ENUM-DNS servers timing each the 3rd preset duration to each default sky
Between corresponding node send detection message, for example, ENUM-DNS servers are at interval of 5 minutes to each
The corresponding node of pre-set space sends detection message.If the corresponding node of pre-set space is normal node,
The corresponding node of pre-set space receive it is described detection message when, feedback response message to ENUM-DNS
Server；If the corresponding node of pre-set space be abnormal nodes, cannot feedback response message extremely
ENUM-DNS servers.
ENUM-DNS servers to the corresponding node of each pre-set space is sent after detection message, and detection is
It is no to receive the response message of the corresponding node feeding back of each pre-set space, if not receiving a certain default sky
Between corresponding node feeding back response message, then judge the corresponding node of the pre-set space as abnormal nodes.
Otherwise, namely the response message of the corresponding node feeding back of a certain pre-set space is received, then judges that this is preset
The corresponding node in space is normal node.
Afterwards, in ENUM-DNS server statistics distributed cache system abnormal nodes number, work as system
When the number of the abnormal nodes of meter is more than predetermined number threshold value A, namely ENUM-DNS can not be ensured
Data in server with distributed cache system during the uniformity of data, ENUM-DNS servers to
Operational system sends warning message.When the number of the abnormal nodes of statistics is preset less than or equal to described
During amount threshold A, although there are the data and distributed caching in ENUM-DNS servers in theory
The inconsistent possibility of data in system, but in order to take into account the availability of data, it is believed that still can protect
The uniformity of data in data and distributed cache system in barrier ENUM-DNS servers.It is described default
The value of amount threshold A is configured according to the NRW replication policies that the distributed cache system is adopted,
For example, if the distributed cache system adopts 3-2-2 replication policies, the predetermined number threshold value A
Value be set to 3, when in the distributed cache system exist more than 3 node for abnormal nodes when,
The uniformity of the data in ENUM-DNS servers and data in distributed cache system cannot then be ensured.
Now, ENUM-DNS servers send to operational system and alert, and do not allow operational system or SPN
Continue the data that subscription and unsubscription is issued to ENUM-DNS servers, to ensure ENUM-DNS servers in
Data and distributed cache system in data uniformity.Namely closing receives operational system or SPN
The function of the data for issuing, at interval of first preset duration new data file is not regenerated, until
System recovers normal.
Further, in the present embodiment, step S50 includes：
Step a, when the response message of the corresponding node feeding back of a certain pre-set space is not received, updates not
Receive the number of times of the response message；
Step b, judges the number of times whether more than or equal to preset times, wherein when not receiving the response
When the number of times of message is more than or equal to preset times, the corresponding node of the pre-set space is abnormal nodes.
Judge whether the corresponding node of each pre-set space is abnormal section in distributed cache system to improve
The accuracy of point, in the present embodiment, ENUM-DNS servers are sending every time detection message to each
After the corresponding node of pre-set space, if the response for not receiving the corresponding node feeding back of a certain pre-set space disappears
Breath, then update the number of times of the response message for not receiving the corresponding node feeding back of the pre-set space.
Whether ENUM-DNS servers judge the number of times more than or equal to preset times, described pre- when not receiving
If the number of times of the response message of the corresponding node feeding back in space is more than or equal to preset times, judge described pre-
If the corresponding node in space is abnormal nodes.For example, if arranging the preset times for 3 times, when
ENUM-DNS servers send 3 detection message to the corresponding node of each pre-set space, if
ENUM-DNS servers all do not receive the response of the corresponding node feeding back of a certain pre-set space for 3 times and disappear
Breath, then judge the corresponding node of the pre-set space as abnormal nodes.
The scheme that the present embodiment is provided, ENUM-DNS servers timing sends detection message to the distribution
The corresponding node of each pre-set space in formula caching system, and detect whether to receive each pre-set space pair
The response message of the node feeding back answered, in the response for not receiving the corresponding node feeding back of a certain pre-set space
During message, the corresponding node of the pre-set space is judged as abnormal nodes, ENUM-DNS server statistics
The number of abnormal nodes in the distributed cache system, when the number of abnormal nodes is more than predetermined number threshold
During value, namely the data in it can not ensure ENUM-DNS servers and data in distributed cache system
Uniformity when, send warning message to operational system, it is thereby achieved that take into account the uniformity of data with
Availability, further increases the reliability of ENUM-DNS servers.
Further, data managing method fourth embodiment of the present invention is proposed based on any of the above-described embodiment,
In the present embodiment, the data managing method also includes：
Step c, when the data file for having node in the distributed cache system breaks down, according to described
The file directory of node, copies successively the corresponding data file of the file directory to institute from secondary node
State node.
Due to the complexity of IMS network environment, distributed cache system is possible to that bust occurs,
The data for causing the corresponding node of some pre-set spaces are all lost, or data it is unreliable the problems such as.This
When, need to recover the data of these abnormal nodes for data fault occur.In the present embodiment, often
All there is a back-up system in individual distributed cache system, under normal circumstances, the back-up system it is standby
The data preserved in node are consistent with the data that the distributed cache system is preserved.To described distributed
When the data of abnormal nodes are recovered in caching system, according to the file directory of the abnormal nodes,
The corresponding data file of the file directory is copied in the secondary node of back-up system successively to the abnormal section
Point, so as to complete the recovery of the data of the abnormal nodes.If the file directory of abnormal nodes has also been damaged
It is bad, namely when can not copy data file from secondary node by file directory, then reset distribution
The corresponding pre-set space of each node in formula caching system, ENUM-DNS servers are reinitialized,
The data preserved in the secondary node of back-up system are all copied into successively the distribution after the completion of initialization
In formula caching system on the corresponding node of each pre-set space.
In the present embodiment, when the data to abnormal nodes are recovered, only need to be according to the abnormal section
The file directory of point, copies successively the corresponding data file of the file directory to described from secondary node
Abnormal nodes, you can complete the recovery of the data of abnormal nodes, without copying all of data file,
It is thereby achieved that the fast quick-recovery of data, so as to further increase the reliability of ENUM-DNS servers
Property.
