Step 401, File Agent safeguard that the file of its corresponding file server sends tabulation, this document sends the file send state information that all respective file servers of this document agency have been preserved in tabulation, comprises the transmit status of the overall budget number of the position of current transmission file listed files in internal memory, current transmission file, the bag sequence number that has sent, current bag, the transmit status of current file and the filename of current file.
Step 402, File Agent are regularly inquired about this document and are sent tabulation, obtain the file send state information of each file server.
Step 403, according to the file send state information, judge whether the current file of this document server is sent completely, if, then go to step 404, if not, then go to step 406.
Step 404, the tabulation of File Agent inquiry file judge whether to exist the file that does not send to file server, if, then go to step 405, if not, then finish, return step 402 after a while.
Step 405, File Agent send first bag of next file to file server, and the file send state information of transaction file server, are sent completely up to All Files, return step 402 after a period of time.
Step 406, File Agent judge whether the bag of current file is sent completely, if, then go to step 407, if not, then go to step 408.
Step 407, send next bag, the transmit status of update package all is sent completely up to the bag of current file, and returns step 404.
Step 408, send the current bag of current file, all be sent completely up to the bag of current file, and return step 404.Since the listed files in the internal memory be with hard disk in file done File mapping, even file or bag have sent half like this, File Agent or file server are closed, and still can continue transmission after starting once more, but packets need are transmitted whole bag again.So-called here breakpoint transmission that Here it is.
File server is received the file bag of File Agent transmission, and the file bag is saved in the local file, if preserve the failure of file bag, then sends the order that retransmits the current file bag to File Agent.
After the file of a file server is sent completely, File Agent will be uploaded the file of next file server, and so circulation sends file in real time to all corresponding file servers.
Above flow process has been described the reciprocal process of File Agent and file server, whether wherein check has new file can guarantee the real-time Transmission of file in the listed files, because in case new file is arranged, this document information has just joined in the listed files, has just sent to file server as new file then.
The file of the file server that File Agent is safeguarded sends tabulation, write down the file send state information of each file server, owing to be to handle through the memory disk mapping techniques, what so just can guarantee that the information of the file that transmits between File Agent and the file server can safety is saved on the disk, no matter File Agent still is the file server process is died, can breakpoint transmission after restarting.
File for this locality, the file that surpasses a specified time is thought invalid data, also rejected the information of this document in the fileinfo tabulation of File Agent, can not upload, so for the processing of packing of this partial document, for example the file before three days compresses packing, delete original document then, to guarantee the reasonable utilization of disk space.
