The embodiments of the present invention will be described in further detail with reference to the drawings attached hereto.
The business system is a system for realizing a whole set of business processes. The service system comprises a plurality of groups of hosts, each group of hosts comprises one or more hosts and realizes a specific service function. Because the service state can be updated along with the progress, the service system frequently needs to update the service parameters corresponding to the updated service state to the corresponding host, thereby achieving the purpose that the service function of each host is adjusted along with the service state in time. The service parameters are parameters required by the host to realize specific service functions, such as service parameter product quality grades, and the host realizing service function payment performs different payment operations according to different grades of product quality.
The overall architecture diagram of the service parameter updating system provided by the application is shown in fig. 1.
Each part is as follows:
application nodes 1-N101: the application hosts 1-N include N application hosts. The application host is a host in charge of realizing specific service functions in the service system. N is an integer greater than 0.
The application hosts 1-N101 divide N application hosts into a plurality of host groups according to service functions, each host group including one or several application hosts, all implementing the same, specific service function. Each host group can flexibly increase or decrease the number of application hosts according to specific requirements. Each application host loads a specific service parameter table according to configuration. And after the service parameter updating task is received, the service parameter is updated only when the recording time of the received service parameter updating task is later than the recording time of the service parameter updating in the current memory.
The service parameter updating task comprises at least one service parameter and information of K application hosts in the N application hosts, and each service parameter in the at least one service parameter corresponds to at least one application host in the K application hosts.
Control hosts 1-M102: control masters 1-M102 include M control masters. The control host is a host in the service system, which is responsible for updating the service parameters of the available application hosts in the application hosts 1-N, and ensures that the service parameters of all the available application hosts are updated within a certain time range. M is an integer greater than 0. Wherein each control host is connected with all application hosts. In addition, a service parameter updating task can be executed by only one control node; one control node may perform multiple service parameter update tasks.
The registration host 103: and recording the current available application host information and providing the available application host information to the control host. The registration host 103 is an independent subsystem of the service system, and a plurality of the registration hosts can be deployed according to needs.
Shared storage host 104: and recording the state of each service parameter updating task. The shared storage host 104 is an independent subsystem of the business system, and may be deployed in multiple numbers as needed.
The service parameter updating method is shown in fig. 2 in conjunction with the flow of fig. 1, and the service parameter updating system and steps will be described in detail in conjunction with fig. 1.
Step 201: and the first control host sends a service parameter updating task to the shared storage host.
The first control host is any one of the M control hosts; the service parameter updating task comprises at least one service parameter and information of K application hosts in the N application hosts, each service parameter in the at least one service parameter corresponds to at least one application host in the K application hosts, and K is an integer greater than 0; and the service parameter updating task is used for indicating each application host in the K application hosts and updating parameters according to the service parameters corresponding to the application hosts.
Step 202: and the first control host sends the service parameter updating tasks to the N application hosts.
Step 203: and the K application hosts receive the service parameter updating tasks.
Step 204: and the K application hosts return the result of parameter updating to the shared storage host.
Step 205: and the shared storage host determines the result of parameter updating of the K application hosts.
Step 206: and the first control host acquires the results of parameter updating of the K application hosts from the shared storage host.
Step 207: and the first control host resends the service parameter updating task or isolates a plurality of application hosts according to the parameter updating result of the K application hosts.
And if determining that at least one application host parameter updating failure exists in the K application hosts according to the parameter updating results of the K application hosts, retransmitting the service parameter updating task.
Before step 201, the service system also has an initialization phase. At this stage, each of the application hosts 1-N101 sends registration information to the registry host 104; control hosts 1-N102 obtain registration information for the N application hosts from the registration host 104. At this stage, the control hosts 1 to N102 already know that the application host having the registration information in the registration host 104 is an available application host, the control hosts 1 to N102 only send to the available application host, and the default application hosts 1 to N101 are all available in steps 201 to 207.
When a service parameter needs to be updated, the first control host receives a service parameter updating task from other external systems. If the first control host fails, the backup host of the first control host receives the service parameter updating task, so that the effects of eliminating single-point hidden dangers and having high fault tolerance are achieved.
Step 201 is performed after the initialization phase has been completed.
In step 201, it should be noted that the service parameter update task further includes a timeout time. All service parameter updating tasks are stored by adopting a bucket dividing strategy, wherein the bucket dividing strategy is to place a task corresponding to an overtime moment in the same block, so that the subsequent isolation processing of different block contents is facilitated and the unified processing of the same block content is performed.
As shown in fig. 3, for each service parameter update task inserted into the shared storage, the timeout time of the task is determined during insertion, and the service parameter update task is placed into a different block according to the timeout time, so as to control the host to obtain the block meeting the timeout time currently for performing timeout processing. If the business parameter updating task corresponding to the overtime moment 1 is put into the block corresponding to the overtime moment 1; the timeout time 2 and the timeout time n also have corresponding blocks.
In step 202, the first control host sends the service parameter update task to the N application hosts according to the registration information of the N application hosts. The first control host only sends the service parameter updating task to the application host with the corresponding registration information.
In step 203, for a first application host, if the service parameter update task includes information of the first application host and service parameters corresponding to the first application host, the first application host updates the service parameters corresponding to the first application host, and the corresponding application hosts included in the service parameter update task are the K application hosts. The first application host is any one of the N application hosts. If the application host is deployed with a shared memory, that is, a memory accessible by processes in the host, the service parameter can be written into a storage area in the shared memory corresponding to the relevant process.
In step 204, if the service parameter update task does not include the information of the first application host or the service parameter corresponding to the information of the first application host, the first application host returns a parameter update success to the shared storage host 104;
or, the first application host returns a parameter update result for updating the service parameter corresponding to the first application host to the shared storage host 104; the parameter updating result comprises parameter updating success and parameter updating failure. The parameter updating result further includes identification information of the application host, so that the shared storage host can obtain the parameter updating result of the specific application host.
It should be noted here that the control host sends the service parameter update task to all application hosts, regardless of whether the service parameters of a certain application host need to be updated or not. The first application host determines whether to update the service parameters according to whether the service parameter update task includes the information of the first application host or the service parameters corresponding to the information of the first application host, and if so, the service parameter update is performed.
The application host supports the service parameter updating task to update the parameters out of order, and adds version information to each parameter updating by the application host, wherein the version information at least comprises the modification times and the modification time of the service parameters. The application host enables the newly modified service parameters to cover the old service parameters through the version information, and the old service parameters cannot cover the new service parameters, namely asynchronous disorder of service parameter updating tasks is supported, and the sequence is finally kept.
The first application host updates the service parameters and has two conditions of failure in parameter updating and success in parameter updating; for example, the failure of updating the parameters is caused by the fact that the memory usage of the application host is too large, so that the service parameters cannot be written into the memory.
In addition, the application host returns the information of the application host except that the parameter updating fails or the parameter updating succeeds, so that the shared storage host can timely acquire the state information processed by the service parameter updating task.
In step 205, in addition to the application host actively sending the state information of the service parameter update task processing to the shared storage host, the shared storage host also determines the result of the parameter update of the K application hosts according to the timeout time of the service parameter update task processing.
And if the first application host does not return successful parameter updating before the overtime, the shared storage host determines that the parameter updating of the first application host fails.
In step 206, the first control host obtains a result of updating parameters of the application hosts corresponding to the information of the K application hosts from the shared storage host every a preset time period. The preset time length may be set according to a specific service scenario, for example, the interval time length between the service parameter update task and the timeout time is a preset time length.
In step 207, the first control host reads the result of the parameter update of the corresponding service parameter update task from the block stored just according to the timeout time, and after the result is obtained, if all the parameter update results returned by the K application hosts are successful in parameter update, the shared storage host deletes the service parameter update task.
And if it is determined that at least one application host parameter updating failure exists in the K application hosts according to the parameter updating results of the K application hosts, the service parameter updating task is failure, and the first control host resends the service parameter updating task. And if the first control host has other service parameter updating tasks, the first control host preferentially processes the service parameter updating tasks which need to be retransmitted.
And after the first control host resends the service parameter updating task, the N application hosts receive the service parameter updating task again. And the above steps are repeated. Moreover, the application host also supports the business parameter updating task.
If the first control host obtains the result of parameter updating of the application hosts corresponding to the K pieces of application host information, that is, the number of times of failure in parameter updating is greater than or equal to X times, the first control host sends a deletion notification to the registered host; the deletion notification is used for indicating the registration host to delete the registration information corresponding to the first application host; x is an integer greater than 1. The process of deleting the registration information corresponding to the first application host by the registration host is referred to as isolating the application host from other available application hosts.
In the embodiment of the invention, a plurality of control hosts responsible for the sent service parameter updating tasks are provided, so that single-point hidden danger is avoided, the service parameter updating tasks can indicate K application hosts in N application hosts to carry out service parameters corresponding to the application hosts, the service parameters updated by all the application hosts are not required to be consistent, and the corresponding service parameters are ensured to be independently updated by all the application hosts.
