Problems solved by technology

[0017] The problem to be solved by the present invention is to provide a method that makes the replication to each slave directory not affect each other, especially suitable for occasions where the network environment is relatively poor, that is, the network is not stable enough, and the connection to some slave directories may have problems. The directory replication implementation method of

Embodiment Construction

[0035] The present invention will be described in detail below according to the accompanying drawings and specific embodiments.

[0036] Such as figure 1 As shown, in the existing directory copy operation method, the following steps are included:

[0037] Step 101: Create a duplicate public log file in the main directory;

[0038] Step 102: the master directory records the copy header information to copy the public log file, and the copy header information includes the address information of all slave directories;

[0039] Step 103: the master directory records the copied data to the copied public log file;

[0040] Step 104: start a replication process;

[0041] Step 105: the copying process transfers the public log to the private log;

[0042] Step 106: the replication process performs replication to all slave directories according to all slave directory address information and replication data in the private log;

[0043] Step 107: The copying process cleans up the pri...

Abstract

The invention provides a directory replication implementation method based on log splitting. The method includes the steps: generating a public log file for each subdirectory when a replicated public log is generated; starting a replication process for processing the public log and a private log; performing operation for a designated subdirectory and further clearing the replicated log. By the aid of the technical scheme, replication for a plurality of subdirectories can be independently performed, the influence of replication of parts of the subdirectories on replication of the other subdirectories is avoided, so that directory replication stability and reliability are improved, the subdirectories are in one-to-one correspondence to private log files, the problem of incapability of clearing replicated private log files in the replication process due to replication problems of individual subdirectories is avoided, overstocking of the replicated logs is further avoided, and normal subdirectory replication operation is ensured.

Description

technical field [0001] The invention relates to the field of directory service systems, in particular to a method for implementing directory replication based on log splitting. Background technique [0002] With the development of the Internet, the requirements for standardized management and efficient access to various data resources have become very urgent. Directory service technology is a new technology that emerges and develops rapidly under such a background. The directory service system is a new type of special database system used for distributed storage and fast query of network data resources. It is specially designed for information services whose retrieval frequency is much higher than that of data update. Such as library book index system, network resource management system, organization personnel management system, certificate management system, single sign-on system, etc. [0003] As an important part of the distributed storage of the directory service system...
