Embodiment
The method that embodiments of the invention provide a kind of main preparation system to safeguard; Change in the scene of back-up system to solve, cause part software unit information inconsistency, influence the problem that partial function provides so that system reliability reduces because of the manual operation carelessness in the replacing standby host process in prior art.
Below in conjunction with accompanying drawing, specific embodiments of the invention describes in further detail.
The method that embodiments of the invention provide a kind of main preparation system to safeguard; Its applied scene is as shown in Figure 1, comprises main frame and standby host, and wherein Resource Server operates in the main frame; The resource client operates in the standby host, and decision was from the role in whole system when main frame and standby host started.Resource Server is in charge of all software resources in the host computer system, and these resources all leave in the non-volatile media and carry out unified management; The resource client is accomplished the renewal to software resource according to the indication of Resource Server; Transmit passage and be used for mutual between main frame and standby host, the resource etc. that interaction content comprises resource sequence information and need copy to standby host.
As shown in Figure 2, the method that this main preparation system is safeguarded may further comprise the steps:
Step s101, main frame detect standby host and start.
Concrete, main frame has the Resource Server function in the main preparation system, and standby host has the resource client functionality in the main preparation system.Main frame can detect the standby host startup and standby host is monitored.The concrete mode that main frame detects the standby host startup can be software mode and/or hardware mode.Software mode is meant the mode through agreement, and promptly standby host initiatively sends a message and gives main frame after startup, and main frame thinks that standby host starts after receiving this message; After hardware mode was meant that standby host starts, the hardware of standby host was through interrupt mode notice main frame, and main frame is had no progeny in receiving this and thought that standby host starts.
In addition, during system initialization after startup of main frame or standby host, need register the software resource information of this locality.The resource here is meant the various static resources that relate in the version management, possibly comprise the program control document of BIOS (Basic Input Output System, basic input output system) file, program file, various logic device etc. in form; Log-on message comprises: the condition code of resource, memory location, the mode that comes into force (come into force after resetting or come into force), read the resource method, write the resource method, in the resource availability determination methods (refer to judge resource content whether complete etc.) one or more.
Main frame and standby host be these information of unified management in active and standby machine respectively.Because active and standby machine possibility version is inconsistent, the resource content of management there are differences separately.The form that administrative institute adopts can be used like the description in the following table 1:
Table 1 is used for the active and standby machine version management form of reference
| Resource type | The resource version | The memory location | Planning length | Mode comes into force | … |
| System application | 1.2.5 | 0x87320 | |
1 | … |
| The system bios program | 3.5.1 | 0x72340 | 0.5 |
1 | … |
| Languages | 2.5.1 | 0x23150 | 2M | 0 | … |
| … | … | … | … | … | … |
Wherein, define for attributes such as the condition code of each resource through resource type, resource, memory location, planning length, the modes that comes into force.Wherein the condition code of resource is used for the resource file of unique identification appointment, can get the version information of this resource file, also can be also representes through the resource file content being carried out the numerical value that arithmetical operation obtains.What wherein need specify is the mode of coming into force, and defines with 0/1 pair of mode of coming into force in the present embodiment, concrete, and " 1 " can be represented and need come into force, and come into force after can representing and resetting " 0 "; Can certainly use other definition modes, can represent and need come into force like " 0 ", come into force after can representing and resetting " 1 ".
Step s102, main frame send message and receive the response of standby host to standby host, obtain the resource that needs copy to standby host according to response.
The concrete method of obtaining the resource that need copy to standby host can comprise:
Method 1: main frame obtains the resource sequence of the support copy function of its local storage; And the resource sequence that gets access to sent to standby host; Standby host is found out the resource sequence of its support from these resource sequences, respond the condition code of each resource in the resource sequence in the standby host to main frame then; After main frame receives the response of standby host, the resource sequence that duplicates according to these needs of information decision of the resource sequence of the standby host that carries in the response.For example; The condition code of each resource in the resource sequence of the condition code of each resource and standby host transmission in the main frame comparison own resource sequence; When the condition code of same asset is inequality on the condition code of certain resource and the main frame on the discovery standby host (for example the condition code of certain resource is designated as than older version on the standby host), this resource is added this resource that need duplicate.
Method 2: main frame sends message to standby host, requires standby host to report the resource sequence information of standby support; Standby host responds the condition code of each resource in the resource sequence in the standby host to main frame; Main frame obtains the resource that this need duplicate according to the resource sequence information of standby support in the response.For example; The condition code of each resource in the resource sequence of the condition code of each resource and standby host transmission in the main frame comparison own resource sequence; When the condition code of same asset is inequality on the condition code of certain resource and the main frame on the discovery standby host (for example the condition code of certain resource is designated as than older version on the standby host), this resource is added this resource that need duplicate.
Method 3: main frame obtains the resource sequence of the support copy function of its local storage; And the resource sequence that gets access to sent to standby host; Standby host is found out the resource sequence of its support from these resource sequences; And according to the condition code of each resource in the resource sequence, this resource sequence that need duplicate and notify main frame of making a strategic decision; The condition code of each resource in the resource sequence of the condition code of each resource and main frame transmission in the standby host comparison own resource sequence; When the condition code of same asset is inequality on the condition code of certain resource and the main frame on the discovery standby host; This resource is added response message and notifies main frame, and main frame obtains the resource that needs copy to standby host according to the response of standby host.
Final host computer gets access to and comprises information such as whether needing resetting system after resource sequence that all resources that this need duplicate are formed and each resources duplication finish.Wherein, at first the needs resource that just can come into force that resets preferentially is recorded in the resource sequence.
Step s103, host-initiated resources duplication are handled, and the resource that the needs that get access to is copied to standby host copies to standby host one by one.
Specifically, this reproduction process is to use the process of corresponding resource on each resource updates standby host on the main frame.Reproduction process adopts the transmission passage to carry, and cooperates this process of completion by Resource Server on the main frame and the resource client on the standby host.Transmitting passage is used for sending to standby host to the resource information on the main frame and correctly assembling on standby host.Because it is shared transmitting passage, each resource file all adopts identical handling process in the transport process.Different is: in main frame, because the medium of each resource storage is different with the address, and difference to some extent when reading each resource information; In standby host, also there is difference in processing mode when upgrading each resource information equally.Therefore when accomplishing this step, only need consider its different read-writes processing and get final product that these processing methods are registered in front for each resource file.
After step s104, resources duplication were accomplished, main frame judged whether standby host is resetted according to the content of resource, then standby host is resetted when needing, otherwise does not carry out any action.
Specifically, after main frame was accomplished the action of resources duplication, if need not reset standby host behind the resources duplication, then reproduction process was accomplished automatically; Otherwise main frame issues the instruction of the standby host that resets and gets into the monitor state to standby host once more, and standby host is accomplished reset processing according to this instruction simultaneously, can start once more after resetting, and after this active and standby machine can need copy to the resource of standby host again through agreement formation.So repeatedly, need not carry out the standby host that need not reset after any replication actions or replication actions are accomplished up to active and standby machine, so just explain that the whole process of duplicating automatically finishes, after this active and standby machine gets into normal operating state.
Below in conjunction with a concrete application scenarios, the method that the main preparation system in the embodiment of the invention is safeguarded is described in detail, and is as shown in Figure 3, specifically may further comprise the steps:
Step s201, main frame and standby host start, and the resource information in the system is registered.
Step s202, main frame detect standby host and start.
Step s203, main frame find that standby host starts the back and supports all resource sequences of copy function to send to standby host through transmitting passage to it.
Step s204, standby host are found out the resource sequence of its support from all resource sequences that main frame sends, give main frame the information responses such as resource version that support then.
After step s205, main frame receive the response message of standby host, generate the resource that these needs duplicate according to the resource sequence information of carrying in the response message.
Step s206, host-initiated resources duplication are handled, and the resource that needs is copied to standby host copies to standby host one by one.
After resources duplication in step s207, the main frame was accomplished to the process of standby host, main frame determined whether to reset standby host.
Step s208, standby host restart.
