Abstract
The present invention provides a kind of server RTC clock synchronous method, belong to management system design field, the present invention is based on RTC synchronised clock chips, design domestic processor driving, synchronization system time to RTC, RTC clock configuration main power supply, upper electricity just reads RTC clock to outband management system software every time simultaneously, deadline proofreads, and keeps outband management system and the uniformity of server OS time, realizes the outer real-time management of band to complete machine.
Description
Technical field
The present invention relates to management system designing technique, more particularly to a kind of server RTC clock synchronous method.Solve domestic
The clock consistency design problem of processor-server platform lower platform system and outband management system is a kind of for solving state
Produce processor-server platform outband management system clock and the inconsistent method of managed object clock, it is possible to achieve to domestic place
The clock correction of device server platform outband management system is managed, the time correctness of holding outband management system is a kind of to state
Produce the effective ways of processor-server platform outband management system time check and correction.
Background technology
In recent years, with the continuous progress of domestic processor-server, the management system design of domestic processor-server
Technology is also more and more crucial.Domestic processor-server operational efficiency and the management skill using reliability are effectively improved as a kind of
Art, outband management technology is just increasingly being widely applied in actual exploitation design, processing management system that can be independent
Data, be in industry also gradually taken seriously, although its designing technique is more ripe, but in domestic processor clothes
Also there is the place of raising to be optimized under business device platform, such as to the synchronous design method of the clock of outband management system.
At present, in the design of outband management system, management of record and management daily record to management information etc. to be based on
The system time of artificial setting outband management system, this method can realize the set of time to outband management system, and protect
The time of outband management system and the time consistency by pipe server are held, but the operation of this method is relatively complicated, it is necessary to people
For record, each system boot needs to set system time manually, is easily caused operating error, and can give the reality of management data
When property brings very big uncertainty, validity of the reduction outband management system to Data Management Analysis result.
The content of the invention
Based on problem above, the present invention proposes a kind of server RTC clock synchronous method.Based on domestic processor platform
The RTC clock simultaneous techniques of design, effectively can be proofreaded the time of outband management system in real time, be realized and platform system time
It is consistent, effectively increases the record time real-time of management data and the accuracy of management result, improve domestic processor
The reliability of the management system function of platform.
The technical scheme is that：
A kind of server RTC clock synchronous method, is mainly based upon RTC synchronised clock chips, designs domestic processor driving, together
Walk system time and arrive RTC, RTC clock configuration main power supply, while outband management system software every time upper electricity just reading RTC when
Clock, deadline check and correction, keeps outband management system and the uniformity of server OS time, realizes outside to the band of complete machine
Real-time management.
Based on domestic processor rack server, RTC clock chip by I2C buses respectively with domestic processor and
Outband management system processor is connected, when the domestic processor operating system of design realizes dynamic synchronization native operating sys-tern and RTC
Clock, while outband management system reads the time of RTC clock storage to local in real time, so as to realize outband management system and local
The time synchronized of operating system.
Concrete methods of realizing is as follows：
1）When system boot is run, then start-up operation system time synchronization drive software obtains server by drive software
Local system time；
2）The local zone time of acquisition is write RTC clock chip by time synchronized drive software, and updates RTC clock check mark position
Information is 1, and RTC clock is proofreaded, it is ensured that RTC clock is consistent with the operation system clock；
3）Outband management system reads RTC clock after starting be used to initialize outband management system time, then, and the cycle reads
RTC clock updates check mark position information, is not operated then if 0, RTC clock and real-time update band are read if 1
The time of outer management system.
Brief description of the drawings
Fig. 1 is the schematic circuit schematic diagram of the present invention；
Fig. 2 is RTC clock synchronization mechanism flow chart.
Embodiment
More detailed illustrate is carried out to present disclosure below：
The RTC clock simultaneous techniques particular content of the present invention is as follows
1st, hardware principle is designed, domestic operating system nucleus time synchronized drive software is changed, realizes and is obtained by drive software
The native operating sys-tern time, RTC clock information is read and write by low speed bus I2C while realizing；
2nd, during each server start, the local zone time of acquisition is write RTC clock chip, and RTC by time synchronized drive software
It is 1 that clock, which updates check mark position information, and realization is proofreaded to RTC clock, it is ensured that RTC clock and the operation system clock one
Cause；
3rd, RTC clock is read after outband management system starts to be used to initialize outband management system time, and then, the cycle reads
RTC clock updates check mark position information, is not operated then if 0, RTC clock and real-time update band are read if 1
The time of outer management system.
Claims (3)
