The present invention relates to the field of computer communications, and in particular, to an automatic disaster tolerance switching method and apparatus. A Voice Message System (VMS) service is a telecom value-added service. The service is based on a voice message platform and is used for voice mail service. It mainly provides users with the function of receiving and sending voice messages. . The service provides basic functions for users to receive messages and send messages, new message notification functions, personalized mailbox settings, different Class of Service (COS) level functions, etc., in addition to existing interactive voices. In the Interactive Voice Response (IVR) process, users can even access and customize their voicemail through personal portals, WAP portals, and VVM. The broadband intelligent network platform realizes the control of service calls, encapsulation of various protocols, and reconstruction of messages, which well supports the operation of various telecom value-added services.

The following is a description of a partition-level automatic disaster tolerance operation of a VMS voice mail service according to a specific embodiment. FIG. 3 is a system architecture diagram of a partition-level automatic disaster tolerance of a VMS voice mail service according to an embodiment of the present invention, as shown in FIG. The monitoring module is a core module for implementing automatic disaster tolerance at the partition level. It mainly includes the following functions:

1. Periodically check the status of the specified resource: 1) Monitor the DB resource The resource monitoring module detects the DB resource status by some message or command mode. If there is no response or response error, the resource is abnormal. 2) Monitoring the storage resource The resource monitoring module detects the status of the storage resource in a certain message or command mode. If there is no response or response error, the resource is abnormal.

3) The monitoring resource monitoring module of other internal interface resources detects the status of other internal interface resources in a certain message or command mode. If there is no response or response error, the resource is abnormal. The resource monitoring module periodically detects the above modules, and continuously detects that the resource is abnormal after exceeding a certain threshold number. 2. Automatic DR switchover conditions: The resource monitoring module provides the function of detecting and monitoring all other resource modules, identifies the faulty resources, and divides the importance of the impact of the resource modules on the system operation, which has a great impact on the system operation and occurs. The faulty resource module is set to the automatic disaster recovery switching condition. When the conditions are met, automatic DR switching is performed. If the conditions are not met, automatic DR switching is not performed. Only non-critical modules are processed or not processed. At the same time, when the handover is performed, it is further determined whether the spare partition and the standby resource are available, otherwise the condition for automatic disaster recovery handover is not satisfied.

3. Modify the status of the partition and resources when switching: After the conditions of automatic disaster recovery switching are met, the resource monitoring module changes the status of the partition and resources to offline or unavailable, and provides or identifies the reason for offline or unavailable.

4. Control the specified module to stop when switching: When the disaster tolerance is automatically switched, the resource monitoring module provides corresponding commands to control the specified resources of the faulty partition to stop running. Different resource types correspond to different instruction types.

5. The resource monitoring module of the standby partition is notified of the disaster recovery switching event: the resource monitoring module notifies the standby partition resource monitoring module of the switching event when the disaster tolerance is automatically switched.

6. Switching to control the startup of the corresponding module: After receiving the handover notification event of the primary partition resource monitoring module, the standby partition resource monitoring module enables the standby resource module on the standby partition to take over the service.

7. Receive notification from other modules to trigger the switchover: The resource monitoring module provides the function of receiving the notification of other modules to trigger the disaster recovery switchover. The switching conditions and the operations to be performed are the same as those for automatic disaster recovery. In Figure 3, the monitoring module includes the following sub-modules:

1. Status monitoring sub-module: Mainly complete the resource information to be detected from the DB, and then perform status check.

2. Switch operation processing sub-module: Complete the partition switching processing operation. 3. Takeover service control sub-module: mainly handles the handover request from the primary partition and completes the takeover service operation.

4. Active/standby partition offline control sub-module: Mainly completes processing offline requests from the web, completes partition switching or takeover processing.

5, service start and stop control sub-module: Mainly complete the start and stop operation of the module or resource object. 6, SMDB stop processing sub-module: mainly processing requests from the web to stop the main DB, will be used

The DB performs the operation of stopping the service. When a certain DB resource on the primary partition fails, and the resource monitoring module of the partition continuously detects a certain threshold value, it is confirmed that the DB is faulty, and the DB module belongs to a preset key of system operation. The module, the resource monitoring module determines that there is an alternate partition in the partition to which it belongs, and the standby DB exists and is available on the spare partition. The resource monitoring module starts automatic disaster recovery switching, updates the partition and resource status in the database, and stops other related resources. The resource monitoring module of the standby partition is notified of the disaster recovery switching event. The resource monitoring module of the standby partition starts the related standby resource after receiving the notification event, thus completing the automatic partitioning process of the entire partition level. At this point, the voicemail service is still available, and the user experience is no different from normal. This embodiment describes automatic disaster recovery switching at the partition level. If the faulty partition is restored to normal, the resource monitoring module can still automatically detect, update the partition and resource status, and start the related resource module, and notify the standby partition resource monitoring module that the primary partition is restored to normal; the standby partition resource monitoring module receives the master. After the normal message event is restored with the partition, the related standby resources are stopped, and the takeover service is stopped, and the primary partition resource monitoring module is taken over again, so that the system provides the automatic disaster recovery function at the partition level. However, to achieve this function, data synchronization from the alternate partition to the primary partition is required during the disaster tolerance process. The synchronization method and process are similar to the data synchronization of the primary partition to the standby partition. As can be seen from the above description, the VMS voice mail service can automatically switch to the standby system after the failure of the primary system to ensure uninterrupted operation of the service, and the user feels no difference before and after the handover, and is fully automatic. Automatic disaster recovery achieved by smooth switching. While the preferred embodiments of the present invention have been disclosed for purposes of illustration, those skilled in the art will recognize that various modifications, additions and substitutions are possible, and the scope of the invention should not be limited to the embodiments described above. Industrial Applicability The technical solution provided by the embodiments of the present invention can be applied to the field of computer communication, realizing automatic disaster recovery switching of the VMS voice mail service, ensuring the normal operation of the service and the user's indistinct feeling, and performing seamless and smooth switching. Automatic disaster recovery switching.
