Description
Technical field
The present invention relates to a kind of database management systems, more particularly to a kind of database service for railway dispatching center
System belongs to database technical field.
Background technology
Database server is dispatching concentration (the Centralized Traffic being applied in railway system's environment
Control, CTC) system critical component, be mainly used for the critical data of train car dispatching concentration business, such as train
Service chart plan, traffic order, indicates information and other dispatching concentration business datums at operation actual achievement.
Database Server System in the prior art mostly uses double set high-performance data library servers and single set disk battle array
It arranges to realize the storage service of system call centralized traffic data, has the disadvantage that：
(1) single disk array reliability cannot be satisfied the demand that railway despatch concentration system is run steadily in the long term, disk battle array
Row belong to single fault point in systems, once breaking down, no redundance unit can provide standby and support, and disk array
Belong to the critical component in system, necessarily cause Database Systems that can not use once breaking down, and then leads to entire CTC systems
System is unable to operate normally.Occurred multiple disk array in actual use and damage the failure for causing CTC system to be unable to operate normally,
Therefore it needs to consider redundancy scheme for disk array.
(2) existing disk array mostly uses the modes such as RAID, and redundancy is realized between multiple disks, can with certain
By property, but when polylith disk failures in the short time can cause disk array unavailable when beyond the limitation of RAID redundancy schemes.
Occur the failure that polylith disk failures cause CTC system to be unable to operate normally in the multiple short time in actual use, illustrates at present
The mode of RAID is relied only on, reliability level still cannot be satisfied the demand of CTC system 7 × 24 (day × hour) stable operation.
Therefore, in order to ensure that the efficient stable of CTC system is run, system is highly desirable to a reliable and secure operation ring
Border, and realize that database management systems full redundancy fault tolerant mechanism is exactly a urgent problem needed to be solved.
Invention content
In order to overcome the problems of the above-mentioned prior art, the present invention to propose a kind of new number for railway dispatching center
According to library service system.
Technical solution is as follows：A kind of database management systems for railway despatch concentration CTC system, the database clothes
Business system includes first database server, the second database server, the first optical fiber switch, the second optical fiber switch,
One disk array and second disk array；The first database server is separately connected the first optical fiber switch and the second optical fiber
Interchanger, second database server are separately connected the first optical fiber switch and the second optical fiber switch；First magnetic
Disk array is separately connected the first optical fiber switch and the second optical fiber switch as primary database memory, the second disk battle array
Row are separately connected the first optical fiber switch and the second optical fiber switch as redundancy backup archival memory.
Further, the database management systems further include quorum disk array, and the quorum disk array connects respectively
Connect the first optical fiber switch and the second optical fiber switch.
Further, while the quorum disk array realizes the first disk array and second disk array for controlling
Data write-in, active-standby switch and disk array restore function.
Further, first disk array and second disk array are for train car operational plan simultaneously, operation
Actual achievement, traffic order and other dispatching concentration business datums realize that data store redundancy backup.
Further, the first database server and the second database server use Oracle RAC external members.
Further, it is connected using optical fiber between each component.
It is using the advantageous effects that above-mentioned technical proposal is brought：
On the one hand by using double disk arrays and database server using the completely redundant of Oracle RAC external members
Property improves the fault tolerant mechanism of system in the process of running, even if a certain disk array goes wrong, will not influence system
Normal operation realizes data redundancy backup storage, avoids Single Point of Faliure problem, improve the stabilization of database management systems
Property and safety, while meeting the demand that CTC system 7 × 24 is run steadily in the long term.
On the other hand the maintainability for substantially increasing system is horizontal, can be fast in the case where not influencing system normal operation
Quick-recovery disk array.
Description of the drawings
Fig. 1 is the structural schematic diagram of database management systems of the present invention；
Specific implementation mode
The present invention will be described in detail in the following with reference to the drawings and specific embodiments, but not as a limitation of the invention.
Database management systems for railway centralized dispatching system CTC as shown in Figure 1, by being arranged in system structure
Double set disk arrays and optical fiber switch realize data redundancy backup storage, avoid Single Point of Faliure problem, and then improve database
The stability of service system and safety；Database server uses Oracle RAC external members, and it is long-term to meet CTC system 7 × 24
The demand of stable operation.
Database management systems shown in FIG. 1 for railway centralized dispatching CTC system, including database server 1, number
According to library server 2, optical fiber switch 1, optical fiber switch 2, storage A, storage B and arbitration storage, wherein storage A, B and secondary
It is disk array to cut out storage.
Database server 1 is separately connected optical fiber switch 1 and optical fiber switch 2；Database server 2 is separately connected light
Fine interchanger 1 and optical fiber switch 2；Storage A is separately connected optical fiber switch 1 and optical fiber switch 2, and as master data inventory
Reservoir；Storage B is separately connected optical fiber switch 1 and optical fiber switch 2, and as redundancy backup archival memory；Arbitration is deposited
Storage is separately connected optical fiber switch 1 and optical fiber switch 2；Between above-mentioned each component using optical fiber connect, realize quickly, stablize
Data exchange.
In one embodiment, storage A and storage B is for train car operational plan simultaneously, operation actual achievement, traffic order
And other dispatching concentration business datums, realize that data store redundancy backup；While arbitration storage realizes storage A, B for controlling
Data write-in, active-standby switch and disk array restore function.
In one embodiment, database server 1 and database server 2 use Oracle RAC external members, per number
Hardware carrier of the independent calculate node as database is chosen according to library server.
The foregoing is merely presently preferred embodiments of the present invention, therefore can not be interpreted as limitation of the scope of the invention,
It should be pointed out that those skilled in the art, without departing from the inventive concept of the premise, can also make several
Modification and improvement, these are all within the scope of protection of the present invention.
