Abstract

The invention discloses an automatic data unloading and supplying method based on cross-center multiple databases. The method comprises the steps: setting a database parameter table, a data supplyingtask parameter table and a data supplying task log table on a batch running server of each application system; defining a semaphore, a shared memory and a maximum concurrency number of a server systemlevel for the batch running server; defining a database-level semaphore, a shared memory and a maximum concurrency number for each database; reading a database parameter table, obtaining a data supply database list needing to be executed by the server, and creating a new process for each database one by one to independently process the control of data supply tasks and process resources of each database; creating a sub-process, and inquirying a company-level center parameter table at any time. Therefore, the automatic data unloading and supplying method based on the cross-center multiple databases is flexible and trouble-saving, reduces the manpower development cost, avoids excessive centralized data unloading and supplying, and has a disaster recovery function.

Description

technical field [0001] The invention relates to the technical field of databases, in particular to a method for automatically unloading and supplying data based on cross-center multi-databases. Background technique [0002] With the development needs of information security, large enterprises often split their business into business departments under various business segments. Each business department has its own independent application system and database group, and the systems of business departments cannot directly access each other's databases. There is data intersection and dependence between them. For example, department A needs the basic data of department B, and department B may also need some basic data of department A. [0003] The data of the same application system will be stored in different data centers at the same time, and may also be stored in different data centers. In order to play a role in disaster recovery, when a certain data center fails, another app...
