Dry state symbol unit 111 is used for the state of mark current gateway node, and this state comprises two kinds of " normally ", " restarting ".What restart that unit 116 provides gateway node restarts service function automatically.Dry state symbol unit 111 is according to restarting the service of restarting that unit 116 is carried out, check the operating state of gateway node, when gateway node when being working properly, it is " restarting " that dry state symbol unit 111 is revised the gateway node state, after finishing the gateway node reboot operation, it is " normally " that dry state symbol unit 111 is revised the gateway node state.Restarting unit 116 can be a real-time service routine, and the service of restarting in real time is provided.This reset command that pre-sets can be one monthly or by the timing services in sky, realize the schedule reboot of gateway node.
Dry state symbol unit 111 is carried out mark according to the reboot operation of restarting unit 116, reads in real time for bank data Transmit-Receive Unit 112, host data transceiver unit 114, and then determines whether to select this gateway node to transmit data.This dry state symbol unit 111 can be a block system shared drive, also can be the file identifier of a public domain.
Preferably, gateway node 11 also comprises: the timeout treatment unit, be used to judge whether the bank data that host data transceiver unit sends to main frame receives result data in the given time, if do not receive result data at the fixed time, then overtime prompting is sent to the bank data Transmit-Receive Unit, and then result data is sent to front server, like this, front server will resend bank data, to guarantee the property unanimous between the higher and lower levels of data.
In specific implementation process, gateway node can comprise a Main Processor Unit, is used to control the timeout treatment unit, restarts unit and dry state symbol unit, function such as restarts to realize that gateway is seamless.Fig. 4 is Main Processor Unit 118, timeout treatment unit 117, restarts the logical construction block diagram of unit 116 and dry state symbol unit 111, below in conjunction with logical construction shown in Figure 4, describes the operation principle of this plurality of units in detail.
The current state of dry state symbol unit 111 mark gateway nodes.Gateway process all must be checked this dry state symbol unit 111 before sending main frame in the every transaction of processing (this transaction promptly refers to bank data): during when dry state symbol unit 111 marks " normally ", send on transaction is normal; When dry state symbol unit 111 marks " are restarted ", send in the transaction no longer, and return miscue, send on carrying out with other gateway nodes of prompting selection.Dry state symbol unit 111 can be a shared drive, or a public file indications.Bank data Transmit-Receive Unit, host data transceiver unit be the state of reading state indexing unit 111 marks in real time, send data to determine whether to select this gateway node on carrying out.
Particularly, dry state symbol unit 111 comprises: status checkout module 1111 and status indication module 1112, wherein: status checkout module 1111 is used to check the operating state of current gateway process, and check result is fed back to Main Processor Unit 118.Main Processor Unit 118 receives outside reset command, reads respective profiles, obtains the name of the gateway progress of work, searches in the current system, whether has the gateway process of operate as normal: as existing, the gateway operate as normal is described; Do not exist as process, illustrate that gateway starts unusually or not, feeds back to Main Processor Unit 118 with the gateway operating state at last.
Status indication module 1112 is used for the state of mark current gateway node, when Main Processor Unit 118 receives reset command, call status checkout module 1111 and check the state of gateway node, call by result status indication module 1112 according to status checkout module 1111 feedback is " restarting " with status indication then, the stage of returning to be transacted such as enters.After all arm's length dealings were all returned, Main Processor Unit 118 called status indication module 1112 status indication is " normally ".
The processes of returning to be transacted such as timeout treatment unit 117 is used to handle.When Main Processor Unit 118 is " restarting " by calling status indication module 1112 mark gateway node states, gateway node is in rebooting status, no longer receive new data this moment, but also do not withdraw from once, but wait for by this gateway node and send the data of main frame to return on.Stand-by period is controlled by timeout mechanism, at this moment between in, by normal flow, all arm's length dealings are returned.When surpassing this time, this gateway node do not waiting for, sends to the front server overtime prompting of concluding the business.
Behind Main Processor Unit 118 wait timeout processing units 117 end-of-jobs, call the work that unit 116 finishes gateway node of restarting.This restarts the unit can call exiting command of original gateway, perhaps adopts the system command of directly closing gateway process, judges it is to continue reboot operation or orderly closedown then.If orderly closedown; then Main Processor Unit 118 calls status indication module 1112 dry state symbol unit 111 is modified to " normally "; after preventing the normal startup of next gateway, be checked through " restarting " state and cisco unity malfunction, Main Processor Unit 118 withdraws from automatically and gets final product then.Restart if desired, then Main Processor Unit 118 calls status indication module 1112 dry state symbol unit 111 is modified to " normally ", then gateway node is started, and finishes reboot operation.
Need to prove that gateway is restarted two kinds of branches: a kind of is that server (as the above-mentioned program of restarting) is restarted in daily timing; Another kind is need cut off service so that upgrade gateway program (similar repacking program), just is equivalent in this case normally withdraw from, and can carry out operations such as program installation behind the dead halt.
Fig. 5 is the realization flow figure of the uninterrupted service of gateway server, and this flow process comprises the steps:
Step 501 is restarted unit 116 and is started, and this startup can be manual operations, and that carries out gateway server restarts function in real time, and this startups also can be added the timing operation the inside to, realization monthly or the stipulated time per diem restart.Service processes reads configuration file after starting, and obtains parameters such as gateway process name and waiting-timeout time, to finish the initialization operation of process;
Step 502, status checkout module 1111 is checked the current state of gateway node, if work, then enters step 503, if gateway node does not start, then explanation need not the service of restarting, and enters step 509, and returns miscue;
Step 503, if there is the gateway process of normal service, then Main Processor Unit 118 calls status indication module 1112 mark current states for " restarting ", the expression gateway server is in rebooting status;
Step 504, status indication module 1112 mark current states for " restarting " afterwards, according to the predetermined stand-by period, wait and to be transactedly normally return.Waiting time is greater than the transaction stand-by period that sets in advance, and do not return always or in the transaction that terminal wait returned after the time, thinks unusual overtime transaction;
Step 505, after the stand-by period, all arm's length dealings are returned, and Main Processor Unit 118 calls restarts unit 116, finishes all gateway process;
Step 506, after all gateway process were closed, Main Processor Unit 118 called status indication module 1112 mark current states and is " normally ", waits for gateways and starting or updating operation;
Step 507 judges that gateway is upgrading or starts, if gateway needs upgrading, restarts after the unit withdraws from, and can change gateway program, restart operation such as system; If restart gateway operation, then calling status indication module 1112 mark current states is to enter step 508 after " normally ";
Step 508 starts gateway process, finishes that gateway is seamless restarts flow process;
Step 509 does not start if status checkout module 1111 is checked through gateway node, illustrates that then reboot operation does not need, with gateway not starting state feed back to the keeper, to carry out abnormality processing;
Step 510, if do not need to restart gateway, then status indication module 1112 mark current states are " normally ", finish to restart flow process.
Fig. 6 is the workflow diagram of gateway server, and as shown in Figure 6, this flow process comprises:
Step 600, gateway server unit 20 starts, and can be start-up by hand, and this generally is that gateway node begins operate as normal, work such as the configuration file that is used to finish the gateway operate as normal reads, normal initialization;
Step 601, the monitoring service port, gateway server 1 is relations of server and client with front server 3, gateway server is opened a listening port as service end, and this port can read from configuration file, when gateway server started, this port can not be occupied.The bank data Transmit-Receive Unit is at this port, listens socket by setting up frame on the protocol family of appointment and the Socket type, and with the port binding of appointment to this socket, create and monitor socket, read the data of sending on the front server 3, the line data verification of going forward side by side, processing such as transcoding;
Step 602, receive legal data after, check dry state symbol unit, judge whether gateway node is in rebooting status: when being in " restarting ", then enter step 607, and this state is returned to front server; When being in " normally ", then this transaction can normally be carried out, and enters step 603;
Step 603, gateway node is working properly, and New Transaction is placed into uplink data storing unit by application number, waits for reading of host data transceiver unit, and the host data R-T unit will be delivered to respective host on will concluding the business according to different application numbers;
Step 604, after transaction data was put into uplink data storing unit, subprocess taked the blocking type mode to be transacted returning such as downlink data memory cell, and the waiting-timeout time is set, do not return if in the stand-by period, conclude the business, then overtime result is returned to terminal;
Step 605: if wait at the appointed time, then transaction data after the host process or result packing are sent to front server, so far finish a transaction by the time transaction is returned; Or overtime result sent to front server, and return the New Transaction gathering data arrival that step 601 continues to wait for this connection;
Step 606: after the transaction data after will handling returns front server, and check dry state symbol unit, judge whether gateway node is in rebooting status: when being in " restarting " state, enter step 607, close this connection; When being in " normally " state, then return step 601, continue to wait for transaction data;
Step 607: when gateway is in " in restarting " state, return information that gateway is in rebooting status to front server, close this connection, the gateway subprocess withdraws from.
