In one entity device, or, by memory database corresponding for each business, it is arranged in same entity device, but
These entity devices are all the executive agents belonging to the present embodiment.
When each memory database of the synchronizer of internal storage data carries out initialized, due to each internal storage data
Storehouse correspond to an information table, and in this information table, storage has the every terms of information of business, will be to needing synchronization in memory database
Information table, carries out list structure establishment and memory allocation；The access DB data base of each memory database periodic polling needs
The information of the data synchronized.In DB data base, there is the information table of data to be synchronized.Table 1 is the information in DB data base
Table, table 1 is properly termed as Table:CACHE_TABLE_DIC, as shown in table 1:
Information table in table 1 DB data base
| NODEID | TABLEID | TBLNAME | RECSIZE | RECNUM |
| 53100008 | 20082 | IPLIVETVINCSC | 48 | 5000 |
| 20143000 | 81001 | PCMERCHANTINFO | 340 | 1000 |
Wherein, NODEID characterizes the ID of the server that information table is belonged to, and TABLEID characterizes the ID of information table,
TBLNAME characterizes the table name of information table, and RECSIZE characterizes the memory size of information table, and RECNUM characterizes information table
Data volume.
First, each memory database, timing scan DB data base, obtain the first tables of data to be synchronized in DB data base,
There is in the first tables of data to be synchronized the information of the different pieces of information of each business, and these data be provided with priority,
Specifically, owing to the information table of each business has priority, thus the data of information table have priority.
Wherein, DB data base can be arranged on the executive agent of the present embodiment.
For example, the memory database of business of opening an account, periodically access the first data to be synchronized in DB data base
Table；Or, activate the memory database of business, periodically access the first tables of data to be synchronized in DB data base.
Step 102, judge in the first tables of data to be synchronized, if there is the information of data.
In the present embodiment, concrete, each memory database of the synchronizer of internal storage data have accessed DB number
The when of according to the first tables of data to be synchronized in storehouse, need to judge in the first tables of data to be synchronized, if having and be directed to work as
The information of the data of the business that front memory database characterizes.
For example, the memory database of business of opening an account, the first tables of data to be synchronized accessed in DB data base time
Wait, it is judged that in the first tables of data to be synchronized, if there is the information of the data of the business of opening an account.
The most for example, the memory database of business is activated, the first tables of data to be synchronized in accessing DB data base
Time, it is judged that in the first tables of data to be synchronized, if there is the information of the data of activation business.
Step 103, when there is in determining the first tables of data to be synchronized the information of data, according to the first number to be synchronized
According to the priority order of each data characterized in table, each data characterized in the first tables of data to be synchronized are carried out data syn-chronization.
In the present embodiment, concrete, at each memory database of the synchronizer of internal storage data, determine DB data
In the first tables of data to be synchronized in storehouse, the when that there is the information of data of the business characterized for current memory data base,

After storehouse obtains the information of each data in the first tables of data to be synchronized, owing to determining priority in these data, from
And according to the priority order of each data, each data characterized in the first tables of data to be synchronized can be carried out data syn-chronization.
For example, the memory database of business of opening an account, opening of the first tables of data to be synchronized in accessing DB data base
The when of the information of the data of family business, obtain the information of the data of the business of opening an account of party A-subscriber, this data define priority
For the first order；The memory database of activation business, the activation business of the first tables of data to be synchronized in accessing DB data base
The when of the information of data, obtaining the information of the data of the activation business of party A-subscriber, this data defining priority is second
Level；Thus afterwards, it is possible to according to the priority order of two above data, first the data of the business of opening an account of party A-subscriber are entered
Then the data of the activation business of party A-subscriber are carried out data syn-chronization by row data syn-chronization.
The most for example, user buys the memory database of the business of product bag, and first in accessing DB data base is treated
The when of the information of data of the business buying product bag of synchrodata table, obtain the business buying product bag of party A-subscriber
The information of data, the information of data of business of product bag of buying of party B-subscriber, the number of business buying product bag of C user
According to information, defining priority in these three data the most successively is the second level, the first order, the third level, thus just can depend on
Go up the priority order of three data according to this, first the data of the business buying product bag of party B-subscriber are carried out data syn-chronization, so
After the data of business buying product bag of party A-subscriber are carried out data syn-chronization, finally by the business buying product bag of C user
Data carry out data syn-chronization.
The present embodiment is by accessing and obtain the information of data in the tables of data to be synchronized of first in DB data base, the
One tables of data to be synchronized has the information of the data being provided with priority, in determining the first tables of data to be synchronized, there are data
Information when, according to the priority order of each data characterized in the first tables of data to be synchronized, by the first data to be synchronized

The flow chart of the synchronous method of the internal storage data that Fig. 2 provides for the embodiment of the present invention two, on the basis of embodiment one
On, as in figure 2 it is shown, the method for the present embodiment, before step 101, also include:
Step 201, acquisition data, and determine in data whether be defined priority；Determining that data have been determined preferentially
During level, in the information write of the information table that data are belonged to the first tables of data to be synchronized；Determining that data are not by the most preferential
During level, in the information write of the information table that data are belonged to the second tables of data to be synchronized.
In the present embodiment, concrete, the executive agent of the present embodiment can be synchronizer or the clothes of internal storage data
Business device or other device that can perform this method or equipment.DB data base can be arranged on the executive agent of the present embodiment
In.
DB data base determine have new data to be written to DB data base when, DB data base will write new data into
In first tables of data to be synchronized and the second tables of data to be synchronized, the first tables of data to be synchronized is the data that storage is provided with priority
Table, the second tables of data to be synchronized is the table of data that storage is not provided with priority.
First tables of data to be synchronized includes priority list and information data table, includes information table in information data table
Information, information data table is properly termed as Table:CACHE_SYN_URGENT；Priority list sets the priority of information table,
Priority list is properly termed as CACHE_TABLE_URGENT.Having new data to enter in DB data base when, can be by this number
According in the information table putting into the business corresponding with these data, the information that then information table of this business has new data is put
Enter in information data table, owing to the information table of each business sets priority, thus need the information of priority
It is deposited in priority list.Table 2 is information data table, and table 3 is priority list, as shown in table 2 and table 3:
Table 2 information data table
Wherein, CACHEDBNODE characterizes the title of the server that information table is belonged to, and TABLEID characterizes information table
ID, TBLNAME characterize the table name of information table, OP, KEYID, KEYNAME and SYNCOUNT are the additional letter of information table
Breath, GENERATEDATE is temporal information.
Table 3 priority list
| TABLEID | TBLNAME | PRIORITY |
| 20082 | IPLIVETVINCSC | 1 |
| 81001 | PCMERCHANTINFO | 2 |
Wherein, TABLEID characterizes the ID of information table, and TBLNAME characterizes the table name of information table, and PRIORITY characterizes
The priority of information table.
Specifically, DB data base uses DB script to create the process obtaining data, needs to store the letter of new data
Each information of breath table, is written in the first tables of data to be synchronized and the second tables of data to be synchronized.
There is in DB data base the information table of each business, the such as business of opening an account there is an information table, activate business
There is an information table, can be information table set priority, it is known that, in the present invention, priority be for information table for
's.First determine whether whether the new data in information table has priority, i.e. judge whether the information table being written with new data sets
Priority；If it is determined that the new data in information table has priority, now understand and be written with the information table of new data and set
Priority, then the information of the information table that can these data be belonged to is written in the first tables of data to be synchronized, now, is first
The information of information table data belonged to is written in information data table, the priority of the information table then data belonged to
Information is written in priority list；If it is determined that the new data in information table does not have priority, now understand and be written with new data
Information table be not set priority, then the information of the information table that can these data be belonged to is written to the second number to be synchronized
According in table.
Below for creating internal storage data table and the example of SQL statement write data into the first tables of data to be synchronized:
According to above example, it is known that, determine that the new data in information table has priority, now understand and be written with new data
Information table set priority, the information of the information table that can data be belonged to is written in information data table, then will
The precedence information of the information table that data are belonged to is written in priority list.
For example, DB data base has the information table of N number of business, the information table of business of such as opening an account, cancellation industry
The information table of business, the information table revising business etc.；Can be that a part of information table in these information tables sets priority, from
And the information table of M business in the information table of N number of business has priority, wherein M is less than N；New data is written to DB data
The when of storehouse, the business that can be belonged to according to this new data, this new data is put in the information table of this business, can be out
Family business, thus can write the data in the information table of the business of opening an account；Then, however, it is determined that go out the information table tool of business of opening an account
There is priority, can write in information data table in the information table of business of opening an account and be written with new data, and write in priority list
Enter the information of the priority of the information table of the business of opening an account；If it is determined that open an account, the information table of business does not have priority, and meeting exists
Second tables of data to be synchronized writes in the information table of business of opening an account and be written with new data.
Step 102, specifically includes:
Determine whether the information table in information data table has new data, and determine that there is new data according to priority list
The priority of information table.
In the present embodiment, concrete, after each memory database of the synchronizer of internal storage data initializes,
The first tables of data to be synchronized in each memory database periodic timing scan DB data base respectively, may thereby determine that first
In information data table in tables of data to be synchronized, if show that the information table of each business has new data；Thus determining
In information data table in one tables of data to be synchronized, the when of showing that the information table of each business has new data, can be
In priority list in one tables of data to be synchronized, go to determine the priority of the information table of each business with new data.Then go
The priority of the information table according to each business in the priority list in the first tables of data to be synchronized, by have new data and
There are the data in the information table of priority and carry out data syn-chronization.
For example, the first tables of data to be synchronized in the memory database timing scan DB data base of business of opening an account, go
Determine in the information data table in the first tables of data to be synchronized, if show that the information table of the business of opening an account has new data；
If it is determined that open an account, the information table of business has new data, then can the priority list in the first tables of data to be synchronized go
Determine the priority of the information table of the business of opening an account；Then according to the order of priority of the information table of business of opening an account, will have newly
In the information table of the business of opening an account of data, new data carries out data syn-chronization.
Also include:
Step 202, when not there is in determining the first tables of data to be synchronized the information of data, obtain in DB data base
The second tables of data to be synchronized, wherein, the second tables of data to be synchronized has the information of the data being not provided with priority.
In the present embodiment, concrete, if the in each memory database respectively periodic timing scan DB data base
One tables of data to be synchronized, determines in the information data table in the first tables of data to be synchronized, shows in the information table of each business not
There is new data；The most each memory database can obtain the tables of data to be synchronized of second in DB data base, at the second number to be synchronized
According to the information of the information table in table with each business, and now the information table of these business is not provided with priority, thus
Second tables of data to be synchronized has the information of data for arranging priority.Table 4 is the second tables of data to be synchronized, and table 4 is permissible
It is referred to as Table:CACHE_SYN_TABLE, as shown in table 4:
Table 4 second tables of data to be synchronized
Wherein, CACHEDBNODE characterizes the title of the server that information table is belonged to, and TABLEID characterizes information table
ID, TBLNAME characterize the table name of information table, OP, KEYID, KEYNAME and SYNCOUNT are the additional letter of information table
Breath, GENERATEDATE is temporal information.Now, the information table characterized in table 4 is not set table in priority, and then table 4
Storage data in the information table levied do not have priority.
For example, the data having talk business are stored in the information table of talk business when, due to call
The information table of business does not has priority, thus can write in the second tables of data to be synchronized in the information table of talk business and store
New data.
Step 203, judge in the second tables of data to be synchronized, if there is the information of data.
In the present embodiment, concrete, first determine whether the information of the information table of business, table in the second tables of data to be synchronized
Whether bright have new data to have been written in the information table of business, so that it is determined that in the second tables of data to be synchronized, if there are data
Information.
For example, the data having talk business are stored in the information table of talk business when, due to call
The information table of business does not has priority, thus can write in the second tables of data to be synchronized in the information table of talk business and store
New data；Such that it is able to according to the information in the second tables of data to be synchronized, it may be determined that whether go out in the information table of talk business
There is new data, and then determine not to be set in the information table of priority whether have new data to be written into.
Step 204, when there is in determining the second tables of data to be synchronized the information of data, according to the second number to be synchronized
According to the storage order of each data characterized in table, each data characterized in the second tables of data to be synchronized are carried out data syn-chronization.
In the present embodiment, concrete, the memory database in each business determines in the second tables of data to be synchronized have
The when of the information of data, it may be determined that be not set in the information table of priority and have new data to be written into, such that it is able to according to
The each information table characterized in second tables of data to be synchronized, according to the storage order of each data in each information table, by each information table
In each data carry out data syn-chronization, thus each data characterized in the second tables of data to be synchronized are carried out data syn-chronization.
For example, the memory database of talk business can be according to the information in the second tables of data to be synchronized, can be true
Make and the information table of talk business has new data, the information table of talk business there is no priority；At the second number to be synchronized
There is the information of the information table of talk business according to storage in table, thus the memory database of talk business can be to be synchronized according to second
The information of the information table of the talk business of storage in tables of data, finds the new number of talk business in the information table of talk business
According to, simultaneously because each data have storage order in the information table of talk business, and then the memory database of talk business can
With the storage order of the new data according to talk business, the new data of this talk business is carried out data syn-chronization.
The memory database of each business determines the information in the second tables of data to be synchronized without data when, then
Can terminate this time to scan the process of DB data base.
After step 103, also include:
Step 205, the second tables of data to be synchronized obtained in DB data base, wherein, have in the second tables of data to be synchronized
It is not provided with the information of the data of priority；Judge in the second tables of data to be synchronized, if there is the information of data；Determining second
The when that tables of data to be synchronized having the information of data, according to the storage time of each data characterized in the second tables of data to be synchronized
The each data characterized in second tables of data to be synchronized are carried out data syn-chronization by sequence.
In the present embodiment, concrete, in step 103, each data characterized in the first tables of data to be synchronized are carried out
After data syn-chronization, in the information table of the business that will characterize in the first tables of data to be synchronized, the new data stored, count
After synchronizing, the memory database of each business can continue to scan on the tables of data to be synchronized of second in DB data base, goes not have
The new data in information table that is that set priority and that store new data is had to carry out data syn-chronization, this process and 202～step
Process described in 204 is identical.
The present embodiment is by when determining that data have been determined priority, and the information of information table data belonged to writes extremely
In first tables of data to be synchronized；When determining that data are not determined priority, the information of information table data belonged to writes extremely
In second tables of data to be synchronized；Such that it is able to by the information in the information table setting priority, be written to the first number to be synchronized
According in table, owing to information table has the data in priority, and then information table, also there is priority, in the first tables of data to be synchronized
In there is the information of the data being not provided with priority；The information of the information table having priority, not having priority can be divided
Do not store.By first accessing and obtain the information of the data in the tables of data to be synchronized of first in DB data base, determining
The when of having the information of data in one tables of data to be synchronized, in foundation the first tables of data to be synchronized, each data of sign is preferential
The each data characterized in first tables of data to be synchronized are carried out data syn-chronization by level order；Then the second tables of data to be synchronized is accessed
In the information of data, when there is in determining the second tables of data to be synchronized the information of data, according to the second tables of data to be synchronized
The each data characterized in second tables of data to be synchronized are carried out data syn-chronization by the storage order of each data of middle sign, and then first
First will have data advanced person's row data syn-chronization of priority, simultaneously can by data advanced person's row data syn-chronization higher for priority,
To not have data advanced person's row data syn-chronization of priority again；Such that it is able to promptness to be required higher, ageing requirement is compared
