As the equipment of key file to be obtained is constantly connected to network, server can receive the substantial amounts of key that obtains please
It asks, and server will preserve increasing number of key file whithin a period of time, to be carried out when handling key request
The distribution again of matching inquiry and key file, so installation data library software on the server, is provided using database software
Storage, matching, search and query function come manage the equipment identification information of huge number and corresponding key file letter
Breath.When server memory not enough stores growing information content, the portability function of database software offer can also be utilized
It will be on the server of information data Rapid transplant to memory bigger.
When the equipment of networking is very more, for example, up to hundreds of thousands even up to a million when, in order to ensure timely sound
The key file of numerous networked devices is answered to obtain request, server starts multiple processes simultaneously, and a process plays multiple lines
Journey carries out interprocess communication and thread management by server.
Illustrate the detailed process that server through database software obtains key file according to device identification：Server
Process processing receive equipment end acquisition key file request, inquire about whether it has into database according to device identification
Corresponding key file, if not provided, to be stored on server selected under the path of key file one it is unassigned close
Key file.Since the different processes for the acquisition request for running processing distinct device on the server may be selected simultaneously
To same key file, when some process of server gets a unassigned key file folder, can't stand
Equipment is fed back to, but the sequence number in being pressed from both sides according to key file is needed to inquire about whether it is assigned to other in the database
Device identification, it is and anti-if just the sequence number that the device identification and the key file found press from both sides is not recorded in database
Feed apparatus, if the key file folder already be allocated to other device identifications, just look for again again one it is unappropriated close
Key file simultaneously repeats acknowledged journey.The multi-process of server process key request, multithreading be for same database into
Row operation, keep the mutually exclusive operation between process and thread.
