All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

At present, time synchronization between a test server and a host system is realized by issuing date commands to each test server in batches, however, the time of the test server cannot be synchronized with the host system in real time due to different times of receiving and executing the commands by the test servers, so that the problems of failure of timestamp verification and interruption of service test are caused. The test server is a program deployed for service interaction with the mainframe, and can effectively execute a plurality of tasks only by keeping time consistency with the mainframe.

Based on this, the embodiment of the present invention provides a time synchronization scheme for a test server and a host system, and through the scheme, the real-time synchronization of the test server and the host system can be achieved, so that the problems of failure of timestamp verification and interruption of service test in the prior art, which are caused by the fact that the time of the test server cannot be synchronized with the host system in real time, can be overcome.

To facilitate understanding of the invention, the following terms are first described:

daily cutting operation: in order to meet the requirement of a tester for performing special service tests (such as checking account and billing summary) for a special time period (such as the end of a month, the end of a quarter, the end of a year, and the like), a large host in a test environment needs to regularly perform an action of adjusting the time of the host afterwards.

Synchronizing the host time: generally, a timestamp of the host and a timestamp of the server need to be obtained in advance for verification, and if the verification fails, the service is interrupted, so that the time consistency between the server and the host needs to be ensured.

Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

Fig. 1 is a flowchart of a time synchronization method according to an embodiment of the present invention, as shown in fig. 1, the method including:

step 101, in response to the operation of starting the daily cutting, the host time is set as the initial time, and the initial value of the counter is set to zero, and the counting is performed in units of seconds.

Preferably, the initial time of the host may be set to 0 (i.e., 0 hours: 0 minutes: 0 seconds) for convenience of operation.

And 102, determining the current time of the host according to the initial time and the current count of the counter.

Specifically, the initial time and the current count of the counter may be added; and then determining the current time of the host according to the addition operation result.

And 103, performing time synchronization operation on the test server associated with the host according to the current time of the host.

step 501, recording the association relationship between all the mainframe hosts and the test server in the REDIS in real time.

Step 502, the host daily cutting monitoring module monitors daily cutting operation of the large host in real time, and acquires the time (year/month/day: minute: second) of the large host after detecting the daily cutting.

Step 503, the host daily cutting monitoring module sets the host time and the host counter of the large host to 0 and records the time and the host counter into the REDIS.

Step 504, the counter module keeps automatically adding 1 to all host counters in the REDIS every one second interval in real time.

Step 505, the synchronous host module cycles through all test servers IP associated with the daily macro hosts in the REDIS, exits if the cycle is over, and enters step 506 if the cycle is not over.

Step 506, the synchronization host module obtains the host time in REDIS.

Step 507, the synchronous host module obtains a host counter in the REDIS.

In step 508, the synchronization master module performs complement according to the values in

steps

506 and 507, and the generated new master time is the master time in step 506 + the master counter in step 507.
