Wherein, being data volume as the scheduling strategy of data in each source data text is in same priority greater than 5,000,000 source data text, is less than or equal to 5,000,000 source data text and is in time same priority.It is n that this scheduling can be configured into number of passes by configuration file, come the concurrent source data text that will change according to the maximum concurrent process number that disposes in the configuration file, can regulate concurrent number according to the performance of machine, to realize optimizing whole data-switching flow process by the mode of regulating parameter.Specifically the scheduling mode of handling each source data text in the mode of multi-course concurrency as shown in Figure 2, Fig. 2 is the scheduling flow synoptic diagram of the present invention with multi-course concurrency handle data transitions method.
Thread is an entity in the process, the base unit of independently being dispatched and distributing by system, thread oneself does not have system resource, only has the resource that it is essential that any is in operation, but thread can be shared whole resources that process is had with other thread that belongs to a process together.In handling, the single source data text adopts multithreading, specifically the scheduling mode of handling each source data text with multithreading as shown in Figure 3, Fig. 3 is the schematic flow sheet of the present invention with multithreading deal with data text, treatment scheme for single thread is, the resolution data text, judge whether to obtain data text to be processed, if judged result is for being, then according to data conversion rule, the data text is carried out data-switching, data message after will changing then writes the target data text, if judged result then finishes process for not.
After the data-switching process of source data text has been transferred, the data-switching process reads data message in this source data text in the mode of multithreading, the data-switching process is to use configuration file to come the implication of each field of data message in the resolution data text, be called current (corresponding be numbered NF001) as: data text, contained field information has account number (TXN_ID), subject (ACCOUT1), RMB business sign (CURRENCY), remaining sum sign (BALANCE) interest rate is ralocatable mode (RATE_FLG) fixedly, uses configuration file to be defined as follows:
NF001，TXN_ID，1
NF001，ACCOUNT1，2
NF001，CURRENCY，3
NF001，BALANCE，4
NF001，RATE_FLG，5
