Description
Technical field
The invention belongs to the visit and the management in data management field, particularly memory database in the telecommunications BOSS system.
Background technology
Along with the continuous development of telecom operators' business, in its OSS, need the data of management to be " explosion type " growth.Numerous and complicated, huge, the thorny problem that is difficult to manage, use, be expanded into puzzlement development and maintenance personnel of data information.Based on above-mentioned present situation, Linkage company has researched and developed memory database and has come managerial data, solves subproblem effectively.
Yet new problem has occurred again thereupon, and in the process of using memory database, we find, the administration interface that the memory database neither one is unified, and the management maintenance means of data are single and complicated; Those need the application of access memory database to have to operate at above the same station server of memory database, and the distributed computing environment of incompatibility can not be accomplished " equally loaded ", has wasted a lot of system resources.
The present subsidiary product SQL*NET of the Oracle of one of Sybase product, SQL*NET is the remote data access message formula software of Oracle company, is used to realize the communication between client-server, the server-server.SQL*NET TCP/IP is in the network communication protocol layer, and the 5th layer of corresponding ISO/OSI pattern and the 6th layer (being session layer and presentation layer) are so its operation also needs the support of third-party TCP/IP software.
Inspired by this, we associate and can utilize similar techniques to solve contradiction and challenge that memory database is faced.
At above-mentioned situation, Linkage is in the comprehensive accounting system of new edition, and when having improved memory database, having researched and developed provides remote access assembly MEMDB*NET and foreground administration interface MEMDB*ADMIN.Be used to solve the problem that remote data access and main memory DBM are safeguarded under the distributed environment.
Summary of the invention
The present invention seeks to: in prior art, memory database can not adapt to the characteristics that existing application distribution calculates, and does not support remote data access, does not support concurrent visit; Neither one close friend's administration interface, intuitively and efficiently management and access data.Develop a unified remote access interface, support concurrent calling in enormous quantities, develop the administration interface of a WEB mode on this basis, be convenient to the user and observe intuitively and the managing internal memory database.
Technical solution of the present invention is: a kind of memory database remote concurrent access and methods for interface management based on unified interface, adopt the SOCKET communication means that the complete message formula interface (MEMDB*NET agreement) of one cover is set, the user is according to protocol specification, correctly organize message in order to the access memory data, thereby carry out remote access;
Concrete steps are: the message formula network application-level protocol MEMDB*NET based on TCP/IP, according to this agreement organizations message, carry out indirect communication by MEMDB*NET SERVICE process and memory database, access and managing internal memory database; The MEMDB*ADMIN that provides on this basis is with the mode managing internal memory database at WEB interface:
The method of writing the MEMDB*NET protocol component is:
Bottom uses C Plus Plus and socket technology, has used the method for multi-thread concurrent, has guaranteed unified external interface;
The method of writing the MEMDB*ADMIN interface assembly is:
Used TAPESTRY WEB framework, this assembly is encapsulated in a WAR bag the inside, by issue and configuration, has used this assembly.
Remote access assembly MEMDB*NET and foreground administration interface MEMDB*ADMIN provide the message formula network application-level protocol MEMDB*NET based on TCP/IP, as long as the user is according to the agreement organizations message, just can carry out communication indirectly, access and managing internal memory database by MEMDB*NET SERVICE process and memory database.Yan Fa MEMDB*ADMIN provides friendly administration interface in the mode at WEB interface on this basis, the visual degree of enhanced system.
Particularly:
1. solve remote access problem
Memory database has only an example, may be distributed in other above server and use, therefore we utilize the SOCKET communication technology to develop the complete message formula interface (MEMDB*NET agreement) of a cover, the user is according to protocol specification, correctly organize the message just can the access memory data, solved remote access problem.
Support multiple main flow computer language to call this assembly
Java calls
This assembly is the assembly of lightweight, and it is just passable to add jar bag memdb.jar in the classpath that your java uses.
Introduce class wherein then, just can the access memory database
Code snippet 1:
TCPIPConnection?connection＝new?TCPIPConnection(ipAddress，port)；
connection.setReceiveTimeout(20*1000)；
session＝new?Session(connection)；
systemId＝getParam(systemId)；
password＝getParam(password)；
request.setSystemId(systemId)；
request.setPassword(password)；
request.setSystemType(systemType)；
request.setInterfaceVersion((byte)0x34)；
request.setAddressRange(addressRange)；
logger.debug(″Bind?request:″+request.debugString())；
So just set up a session, under the framework of session, just can carry out data access.
Because C/C++ can't accomplish platform independence, can not " once compiling, operation everywhere ", so this mode call relative complex a bit.
