specific Embodiment 1

[0057] Specific embodiment one: one-way data synchronization between master and slave oracle data sources.

[0058] Precondition: Establish two sets of oracle data sources as the master-slave data sources respectively, assuming master data source numbers: S1 and S2; slave data source numbers D1 and D2. The primary data source oracle user is SU, and the secondary data source oracle user is DU. And assign the same authority to SU and DU. Create table TS1 in S1, and create table TS2 in S2; create table TD1 in D1, and create table TD2 in D2; TS1 has the same structure as DS1, and TS2 has the same structure as TD2.

[0059] The first step is to configure data mapping:

[0060] 1) Configure the master-slave database user mapping relationship: SU-S1, SU-S2, DU-D1, DU-D2;

[0061] 2) Configure the database table mapping relationship: TS1-TD1, TS2-DS2;

[0062] 3) Database table field mapping relationship: configure the corresponding relationship between the table fields involved i...

specific Embodiment 2

[0080] Embodiment 2: One-way data synchronization between master and slave file system data sources.

[0081] Prerequisite: Create system users and assign permissions on two network hosts respectively. Suppose the main data source is FS1, and the secondary data source is FD1; the main data source system user is FSU1, and the secondary data source system user is FDU1; the root directory of the primary data source is SP1, and the root directory of the secondary data source is DP1.

[0082] The first step is to configure data mapping:

[0083] 1) Configure the master-slave data source user mapping relationship: FSU1-FDU1;

[0084] 2) Configure the master-slave root directory mapping relationship: SP1-DP1.

[0085] The second step is to configure the system parameters:

[0086] 5) Master-slave data source network address: configure the access URL of the data source;

[0087] 6) Data change trigger frequency: can be configured as 2 seconds;

[0088] 7) Parallel transmission st...

Abstract

The invention discloses a method for unidirectional data synchronization between multiple data sources and relates to the technical field of data storage. Through carrying out mapping management on data between master and slave data sources, configuration management on unidirectional data synchronization between the master and slave data sources and distributed scheduling management on data transmission tasks, making transmission nodes carry out parallel transmission on the data and changing and collecting the data between the master and slave data sources, data synchronization is realized, and the problems of consistency and timeliness of the data between the master and slave data sources of the existing distributed data storage are solved. The method has the advantages of strong fault tolerance, simplicity in operation and data change timing consistency.

Description

technical field [0001] The invention relates to the technical field of data storage, in particular to a one-way data synchronization method among multiple data sources. Background technique [0002] After decades of information technology development, database / file systems have played an important role in data storage in information systems of various industries, especially in the Internet field. However, in recent years, the volume of basic data has grown exponentially, and traditional single-point data storage can no longer meet actual needs. Therefore, many distributed data storage mechanisms and technologies have been derived. However, how to ensure the data consistency and timeliness of multiple data sources in a distributed environment, especially between master-slave data sources, has become a problem that needs to be continuously solved and improved in current distributed data storage. [0003] In many Internet companies, in order to improve system performance, the ...
