Wherein, monitoring modular 71, the network-in-dialing situation for main frame where monitoring local data base；Wherein, above-mentioned
Ground database can be ORD, such as PostgreSQL, but the present embodiment is not limited to that, the present embodiment
The particular type of above-mentioned local data base is not construed as limiting.
Acquisition module 72, during network-in-dialing for main frame where determining above-mentioned local data base when monitoring modular 71, obtain
Take the running situation of above-mentioned local data base.
Recovery module 73, for the running situation of the above-mentioned local data base obtained according to acquisition module 72, when above-mentioned
When the running status of ground database occurs abnormal, the exception run by database High-Available Middleware to above-mentioned local data base
State is recovered.
Wherein, above-mentioned database High-Available Middleware can be Pgpool II, but the present embodiment is not limited to that, this
Embodiment is not construed as limiting to the particular type of above-mentioned database High-Available Middleware.
In above-mentioned local fault recovery device, monitoring modular 71 monitor local data base where main frame network-in-dialing situation it
Afterwards, if the network-in-dialing of main frame where above-mentioned local data base, acquisition module 72 obtain the operation of above-mentioned local data base
Situation, recovery module 73 according to the running situation of above-mentioned local data base, when the running status of above-mentioned local data base occur it is different
Chang Shi, the abnormality run by database High-Available Middleware to above-mentioned local data base is recovered, so as to reality
It is automatic under present various abnormalities to perform database recovery action, manual operation is avoided, the promptness of fault recovery is improved, enters
And the availability of data-base cluster can be improved.
Fig. 8 is the structural representation of another embodiment of the application local fault recovery device.
In the present embodiment, above-mentioned monitoring modular 71, the network of the main frame where above-mentioned local data base is determined is additionally operable to not
During connection, to the network continuous monitoring pre-determined number of main frame where above-mentioned local data base；Wherein, above-mentioned pre-determined number can be
According to systematic function and/or realize the sets itselfs such as demand during specific implementation, the present embodiment to the size of above-mentioned pre-determined number not
It is construed as limiting, for example, above-mentioned pre-determined number can be 10 times.
Acquisition module 72, it is additionally operable to after the continuous monitoring pre-determined number of monitoring modular 71, when above-mentioned local data place
In the network-in-dialing of main frame, the running situation of above-mentioned local data base is obtained.
Further, in the present embodiment, recovery module 73 can include：Judging submodule 731 and addition submodule 732；
Wherein, judging submodule 731, for when above-mentioned local data base is in running status, judging above-mentioned local number
According to storehouse whether in the affiliated cluster of above-mentioned local data base；
Submodule 732 is added, will be upper for when above-mentioned local data base is not in the affiliated cluster of above-mentioned local data base
State local data base and add the above-mentioned affiliated cluster of local data base.
That is, in the present embodiment, if above-mentioned local data base causes due to breaking down or other reasonses
State local data base and do not add the affiliated cluster of above-mentioned local data base, then adding submodule 732 can be in above-mentioned local data base
After running status, above-mentioned local data base is added into the above-mentioned affiliated cluster of local data base.
In the present embodiment, recovery module 73 can include：Judging submodule 731, start submodule 733 and determination sub-module
734；
Wherein, judging submodule 731, for being in off-duty state, and above-mentioned database when above-mentioned local data base
When High-Available Middleware is in running status, collection belonging to above-mentioned local data base is judged by above-mentioned database High-Available Middleware
Group in remote data base whether normal operation；
Start submodule 733, for when judging submodule 731 determines above-mentioned remote data base normal operation, by upper
State database High-Available Middleware and start above-mentioned local data base；
Determination sub-module 734, for when judging submodule 731 determines the non-normal operation of above-mentioned remote data base, passing through
Above-mentioned database High-Available Middleware determines node type of the above-mentioned local data base in the affiliated cluster of above-mentioned local data base；
Start submodule 733, be additionally operable to when determination sub-module 734 determines above-mentioned local data base in above-mentioned local data base
When being host node in affiliated cluster, start above-mentioned local data base.
Further, if it is determined that submodule 734 determines above-mentioned local data base in the affiliated cluster of above-mentioned local data base
In be not host node, then after waiting the remote data base normal operation in the affiliated cluster of above-mentioned local data base, start submodule
Block 733 starts above-mentioned local data base by above-mentioned database High-Available Middleware again.
That is, in the present embodiment, when above-mentioned local data base is in off-duty state, it is necessary to recover to start above-mentioned
During ground database, just whether judging submodule 731 can first determine remote data base in the affiliated cluster of above-mentioned local data base
Often operation, if remote data base normal operation, local data base can be directly initiated by starting submodule 733；And if remote
Journey database also breaks down non-normal operation, this database just illustrated in the affiliated cluster of above-mentioned local data base occur therefore
Barrier, in order to ensure the synchronization of data, starting submodule 733 needs first to start the main section in the affiliated cluster of above-mentioned local data base
Point, it is therefore desirable to determination sub-module 734 first determine above-mentioned local data base in the affiliated cluster of above-mentioned local data base whether be
Host node, if it is, starting submodule 733 directly initiates local data base, and if above-mentioned local data base is at above-mentioned
It is not host node in the affiliated cluster of ground database, then waits the remote data base in the affiliated cluster of above-mentioned local data base normally to transport
After row, start submodule 733 and above-mentioned local data base is started by above-mentioned database High-Available Middleware again, so as to reality
Now when local data base is in off-duty state, start above-mentioned local data base, improve the promptness of fault recovery, and then
The availability of data-base cluster can be improved.
Further, recovery module 73, it is additionally operable to after the continuous monitoring pre-determined number of monitoring modular 71, when above-mentioned local
The network-in-dialing of main frame, above-mentioned local data base are in running status and above-mentioned database High-Available Middleware where database
During in off-duty state, start above-mentioned database High-Available Middleware.
Further, recovery module 73, it is additionally operable to after the continuous monitoring pre-determined number of monitoring modular 71, when above-mentioned local
When the network of main frame does not connect where database, above-mentioned local data base out of service and above-mentioned database High-Available Middleware.
The local fault recovery device that the embodiment of the present application provides can be realized performs database automatically under various abnormalities
Recovery action, manual operation is avoided, improve the promptness of fault recovery, and then the availability of data-base cluster can be improved.
