Abstract
The method for integrating a PDM system based on XML RPC relates to the field of integration of computer application systems and is applicable to the function integration and information integration method of the PDM system. The method comprises the following steps: step 1, a service process is established on the server of the PDM system, a service port is allocated to the service process and the service process is started; when the service process is occupied during start-up, the starting of the service process is failed; a new service port is allocated to the service process till the service process is started successfully; step 2, the service process calls a PDM system interface, establishes a communication link with the PDM system and acquires an access session authorized by the PDM system; step 3, the service process waits a request of a client side; step 4, if the service process receives the requirement from the client side, the service process executes the corresponding function of the PDM system interface and synchronously returns the result to the client end; step 5, the third step and the fourth step are repeated; step 6, the service process receives a shutdown command and shuts down the communication link with the PDM system and then logs out.
Description
Technical field
This method relates to computer application system integration field, is applicable to function i ntegration and the information integration method of PDM system.

Current machinery manufacturing industry have employed the data such as design, production, manufacture that PDM system carrys out management enterprise substantially, for realizing sharing and getting through the Digital production line of whole industry design, production, manufacturing process of business data, just need to realize PDM system and other system is carried out integrated.In order to reach PDM system and other system carries out integrated requirement, when designing PDM system integration interface, mainly contain two kinds of design ways: one is that each interface function of the PDM system integration is designed to a batch program, the result of this interface function is preserved in one file by the form of agreement, perform this batch program by the mode of a service routine utility command row, the content of analysis result file obtains returning results of interface function; Another kind is that each interface function of the PDM system integration is designed to a control desk batch program, is caught the character string that control desk shows by a service routine, and the content of resolving the character string that this is caught obtains returning results of interface function.
There are following shortcomings in these two kinds of integrated approaches:
1) when the interface function of each execution PDM system, all need the License obtaining PDM system, in design peak period, exist and do not cause interface function not run because there is no License.
2) interface function of PDM system can only the mode with batch processing on PDM server run, all need the Session obtaining PDM system to set up to be connected with the access of PDM system at every turn, time is general all at 5 ~ 7 seconds, response efficiency is low, and client-side program needs the result to PDM system interface function returns resolve or judge, execution efficiency is not high.
Summary of the invention
Object of the present invention:
In order to overcome the above problems, provide a kind of based on the practical approach of the integrated PDM system of the communication mechanism of XML RPC, the method principle is simple, programming is succinct, improves response speed and the stability of system integration interface.
Technical scheme of the present invention:
For achieving the above object, the present invention proposes a kind of method based on the integrated PDM system of XML RPC, and this method comprises the following steps:
The first step, sets up service processes on the server in PDM system, to this service processes distribution services port, opens this service processes; If this serve port is occupied during unlatching, then this service processes is opened unsuccessfully, redistributes serve port to this service processes, until this service processes is opened successfully;
Second step, this service processes calls PDM system interface, sets up the communication link with PDM system, obtains the access Session authorized through PDM;
3rd step, this service processes waits for the request of client;
4th step, if this service processes receives the request from client, then performs the function of corresponding PDM system interface, synchronously result is returned client;
5th step, repeats the 3rd step and the 4th step;
6th step, service processes receives out code, closes the communication link with PDM system, exits service processes.
Said PDM system interface comprises with minor function: set up the contiguous function of service processes and PDM system, close function, read documentation function, set up file object function, reading object attribute function, write object properties function and download file function.
In the said first step as required, multiple service processes can be set up, and distribute different serve ports to it, perform the first step step by step rapid to the 6th, realize multi-process service.
Advantage of the present invention:
Owing to have employed above scheme, following advantage can be realized:
1) after service processes of the present invention starts, a License of meeting active obtaining PDM system, can always be further interface and use is provided, can not because of design peak period because License quantity causes the non-serviceable situation of interface not, shorten the time that interface obtains the Session of access PDM system simultaneously, improve the time that interface returns results;
2) PDM system interface of the present invention provides result directly to caller, and caller does not need to resolve result, directly can be used, improve interface service efficiency and stability.
