Abstract
The invention discloses a persistent message publishing method and system. The method comprises the steps that persistent messages stored in a nonvolatile storage device in a persistent mode is read by a persistent message reading device, and a persistent message publishing device stores the persistent messages into a message queue; before the persistent messages are stored into the message queue, whether the message queue is busy is judged, and the persistent message publishing device will be briefly stopped and is in a waiting state if the message queue is busy; after the messages in the message queue are extracted by a message transmitting unit, a notification event is sent to the persistent message publishing device, and the persistent message publishing device is informed to stop waiting; the persistent message publishing device continues to execute from a next statement after a wait statement, and continues to publish messages to the message queue. According to the persistent message publishing method and system, on the condition that a data exchange server receives and transmits a large number of messages, the persistent messages and real-time messages can be transmitted efficiently and reliably, and instantaneity of transmission of the persistent messages is improved.
Description
Technical field
The present invention relates to the data communication field, be specifically related to a kind of dissemination method and system of persistence message.
Background technology
In the message-oriented middleware working mechanism of data switching center, usually there is a number of units to connect many number of units according to the exchange client according to swap server, many number of units are according between the exchange client, by the data exchange service device, carrying out transmission of messages and exchanges data.This machine-processed message sending end and message sink end are realized decoupling zero by the data exchange service device, and sender of the message and message recipient need not also can carry out transmission of messages online simultaneously.
The data exchange service device, when receiving the real-time messages of message sending end, deposits real-time messages in the message queue that receiving terminal is corresponding in, then message is transmitted to the message sink end.In order to guarantee the reliability of transmission of messages, the data exchange service device can be kept at non-volatile memory device by message, when the emergency case such as power down, system exception collapse occurring, data exchange service is thought highly of new startup can load the message that is persisted to non-volatile memory device, and it is transmitted to corresponding message sink end.Message is read in to the process that then internal memory deposits message queue in from non-volatile memory device, be called the persistence data publish.
The data exchange service device is generally supported multiplexing technique, what is called is multiplexed refers to that transmitting terminal is when pocket transmission news (issuing a plurality of receiving terminals or broadcast transmission by message), only to the data exchange service device, send a piece of news, respectively message is transmitted to a plurality of message sink ends by the data exchange service device according to the message route results, this mode has reduced the size of message that transmitting terminal sends to the data exchange service device, save the network bandwidth, improve the efficiency of mass-sending.As shown in Figure 1, transmitting terminal sends a pocket transmission news, only need send a piece of news to the data exchange service device, and server is transmitted to this message a plurality of receiving terminals (Figure 1 shows that three receiving terminals) again.The message number that multiplexing technique makes the data exchange service device to forward to the message sink end is far longer than the message number received from message sending end, and the speed that consequently message forwards is obviously a lot of slowly than the speed of message sink.Message in message queue can not get timely forwarding, finally causes message queue to be occupied full, and part message is only preserved in non-volatile memory device, is not stored in message queue.After message in message queue is forwarded, can discharge the memory space that it takies, at this moment need again the message of persistence to be read in to internal memory, then publish in message queue and forwarded.
In the process of persistence data publish, usually the message receiving apparatus of data exchange service device is also in work, the message also sent at the receipt message transmitting terminal, during also there will be the busy situation of queue.The operation principle schematic diagram that Fig. 2 is prior art issue persistence message, in prior art, be busy situation if there is message queue in persistence data publish process, usually must sleep wait for the time of one section appointment, sleep after overtime and remove again to obtain the state of message queue; If queue just continues sleep and waits for for busy, obtain again the message queue state after overtime, so repeatedly, until message queue is then to continue issue the free time, as shown in step 201-208.As shown in Fig. 2 step 204, the sleep waiting mechanism must be waited until and overtimely just can remove the query messages quene state, if be set as 60 seconds the length of one's sleep, must wait for 60 seconds overtime states that just go the query messages queue.Whether this be that there are the following problems for the idle method of then issuing by repeatedly obtaining message queue: even message queue is idle, also need this wait timeout just to go to obtain the idle condition of message queue, ability initiation message release process, as the time-out time of sleeping is made as 60 seconds, message after having waited for 5 seconds in message queue is removed, also need to wait again the state that just goes the query messages queue in 55 seconds, this just can not be maximized the real-time that forwards of raising message.Although can be by shortening the stand-by period, the frequency that increases inquiry improves the real-time that message forwards as far as possible, the stand-by period is too short, if message queue for a long time in busy condition, the state of frequent query messages queue is also meaningless, can affect performance on the contrary.Therefore, if when prior art exists a large amount of message to send (comprising real-time messages and persistence message), issue persistence message efficiency is low, and it is poor that message forwards real-time.
