Embodiment
For making the technical problem to be solved in the present invention, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The present invention is directed in prior art and much do not support that transaction data storehouse cannot ensure the problem of atomicity in the process of implementation, a kind of disposal route of database, Apparatus and system are provided, by arranging corresponding disposal route for the Exception Type of each atom module, ensure that when Exception Type is rollback type, corresponding atom module can perform corresponding disposal route return back to this atom module run before state, ensure that each atom module has atomicity in execution business, thus ensure that the atomicity that whole data perform.
As shown in Figure 1, the embodiment of the present invention provides a kind of disposal route of database, comprising:
Step 10, the execution flow process of described database is divided into multiple atom module needing to provide atomicity to protect by business demand according to described database successively;
Step 11, the abnormality of the object atom module that Real-time Obtaining is running, determines described abnormal Exception Type according to described abnormality;
Step 12, if described Exception Type is rollback type, obtain first disposal route corresponding with described rollback type and perform described first disposal route make described object atom module return back to this object atom module run before state.
In the above embodiment of the present invention, the execution flow process of database is the whole implementation of this database, and this whole implementation can be divided into multiple atom module business demand, and the plurality of atom module needs to ensure atomicity in execution business.Concrete, the business demand of atom module can be a series of process of the warehouse-in process of data, the pre-statistics implementation of form, the outbound process of data etc., does not enumerate at this.
Concrete, in the practical application of the embodiment of the present invention, such as one section of run time version is as follows:
Make mistakes when such as performing update statement, col2's and col3 and beyond the scope etc. of col1 field; State before at this time just needing whole code block to return back to, needs all data dumps inserted to fall, and performing delete statement can realize.
In the above embodiment of the present invention, described method also comprises:
Step 13, if described Exception Type is not rollback type, obtains second disposal route corresponding with this Exception Type and performs described second disposal route and process described Exception Type.
In the specific embodiment of the invention, in database operational process, various exception may be there is, if Exception Type is not rollback type, when namely there is this exception, without the need to database is return back to previous state, but repaired by additive method, if repaired, continue runtime database; If cannot repair, then report an error and exit, carry out subsequent treatment by other staff or equipment.
Mainly in the present invention Exception Type is divided into rollback type and not rollback type, it should be noted that, the abnormal conditions of rollback type are also divided into various situation, need provide different branch process flow processs, but its final purpose are return back to previous state according to different situations; Rollback type is not divided into various situation yet equally, and database root processes respectively according to different situations.
Concrete, in the above embodiment of the present invention, as shown in Figure 2, step 13 comprises:
Step 131, if described Exception Type is not rollback type, obtains the process code of second disposal route corresponding with this Exception Type prestored;
Step 132, after performing described process code, obtains the abnormality of described object atom module further;
Step 133, if described object atom module does not exist exception, then described database continues to perform next atom module; If described object atom module exists abnormal, then process ends.
In the above embodiment of the present invention, if the Exception Type of object atom module is not rollback type, also obtains corresponding disposal route, and it is processed, if this object atom module does not exist exception after having processed, then continue to run next atom module; If this object atom module also exists other exceptions and cannot process after having processed, then report an error and exit database, be further processed by follow-up personnel or program.
In the above embodiment of the present invention, step 12 comprises:
Step 121, if described Exception Type is rollback type, obtains the rollback code of first disposal route corresponding with this rollback type prestored;
Step 122, performs described rollback code, the state before making described object atom module return back to the operation of this object atom module, and process ends.
In the specific embodiment of the invention, the back off procedure of atom module is by performing the corresponding rollback codes implement write for each abnormal conditions; This rollback code is write preservation in advance for the abnormal conditions that may exist, directly call run this rollback code, make object atom module return back to operation before state.
In the disposal route of the database of the above embodiment of the present invention, by each atom module carry out monitoring, if there is the exception of rollback type in atom module, then perform the first disposal route database is return back to this atom module perform before state; If the exception that atom module occurs is not rollback type simultaneously, also performs the second corresponding disposal route and process abnormal; Ensure that the atomicity in each atom module implementation.
In order to be more preferably the disposal route describing the database that the embodiment of the present invention provides, below in conjunction with Fig. 3, the detailed step of the embodiment of the present invention is further described:
Step S301, business processing atom module 1 starts to perform;
Step S302, judges whether there are abnormal conditions in business processing atom module 1 implementation;
Step S303, if whole code implementation completes smoothly, then there are not abnormal conditions in atom module 1, then continue to perform the code in atom module 2;
Step S304, if there are abnormal conditions in atom module 1, obtains abnormal state information;
Step S305, judges whether according to current state information the rollback operation needing run time version;
Step S306, if needed, performs the rollback operation for basis submodule, the state of database is return back to the state before performing the execution of basis submodule, and program is exited;
Step S307, if do not need to perform rollback operation, then utilizes this abnormal information of the second disposal methods;
Step S308, judges whether continue to perform through the process post code of step S307;
Step S309, performs if can continue, then continue to perform atom module 2;
Step S310, perform if cannot continue, then direct program being reported an error is exited, process ends.
In order to better realize above-mentioned purpose, as shown in Figure 4, the embodiment of the present invention also provides a kind for the treatment of apparatus of database, comprising:
