FIG. 3 shows an example of data copied from a primary system to a secondary system, such as data copied (including configuration data, version tags, and business data) from a CRM/BRM/WEB/HR subsystem.
Step S111: and judging whether the version label is received, if so, executing the step S112, and if not, executing the step S110.
Step S112: and each subsystem of the standby system is deployed.
Step S113: and the standby system carries out online verification test.

Step S115: and the standby system carries out reliability verification.
Step S116: and judging whether the standby system is stable, if so, finishing upgrading, ending the process, and if not, executing the step S117.
Step S117: and rolling back the system. Then, step S109 is executed.
Step S118: the main system rolls back. Then, step S101 is executed.
The main/standby system comprises a plurality of subsystems, and the upgrading of the standby system is mainly completed by data copying generated in the upgrading process of the main system. In the data copying process of the standby system, it is difficult to clearly know the accurate time point of the version upgrade completion of each subsystem, so the conventional method is that the version upgrade data of all the subsystems and the service data during the environment verification period are copied to the standby environment, the version upgrade of all the services is considered to be completed, and then the standby environment is verified. It follows that determining the exact upgrade completion time for each business subsystem becomes particularly critical.
The invention considers that the main system has a node after the upgrade test is finished: upper line (Go Live), shown in fig. 2 at 11/2 morning 6: 00 will declare the main system Go Live and label each sub-application system at this point in time, for example, create a VERSION identification table T _ CRM _ VERSION in the customer relationship management system (CRM) and label the table with the label data: 6.8, plus the time stamp of Go Live. Thus, from 11/1 day 16: days 00 to 11/2 6: the data during 00 are all configuration data for version upgrades.
A trigger is set on the VERSION identification table T _ CRM _ VERSION of the standby system, and when the standby system receives the flag bit written by the main system (for example, when the standby system starts copying from 11/4 day 22: 00, and 23: 00 finds that the tag data 6.8 of the T _ CRM _ VERSION table and the timestamp of the line on the main system have been copied), the trigger calls the utl _ file component of the database to write an operating system local file.
The operating system has a code which is scanned every 5 seconds to detect whether the file is written, once the writing is found, an email or a short message is sent to inform a worker, and the standby system can start verification work, so that manual intervention is not needed, and automatic processing is realized.
As can be seen from the illustration of fig. 2, the original backup system is shown in 11/422: 00 to 29 hours after the data replication and test verification is finished, if the new technical scheme is adopted, the configuration data replication only needs 1 hour, and the test verification is added later, at 11/511: 00 can declare that the upgrade of the standby system is completed, that is, the unavailable time of the upgrade stage of the standby system of the embodiment of the present invention only needs 13 hours, which saves the unavailable time of 16 hours compared with the original scheme.
Fig. 4 shows the principle of an embodiment of the system for fast upgrade of standby environment of the present invention, please refer to fig. 4, the system of this embodiment includes: the system comprises a main system upgrading module, a main and standby system data copying module and a standby system upgrading module.

And the main system upgrading module is configured to restart the main system upgrading after the main system rolls back if the online verification test fails or the reliability verification test fails in the data upgrading process of the main system.
The main system and standby system data copying module is used for starting upgrading of the standby system after the main system passes reliability verification, the standby system judges whether the version label is received or not in the process of receiving the main system data copying, and if the version label is received, the standby system finishes the process of receiving the main system data copying.
