Storage.
A kind of storage method of the status information provided first below the embodiment of the present invention is introduced.
Wherein, a kind of storage method for status information that the embodiment of the present invention is provided can be applied to multi-service process simultaneously
In the case of operation, in the case of the operation of single business process can also be applied to.
As shown in figure 1, a kind of storage method for status information that the embodiment of the present invention is provided, can include following step
Suddenly：
S101：The status information that the business process that currently runs creates for shared drive writes into journey, the shared drive by
The business process of first operation creates；
It should be noted that the status information that business process of each operation can create for shared drive is write into
Journey, to ensure in the status information write-in shared drive itself generated in the process of running.If the business process currently run
For the business process of first operation of operating system, when the business process currently run is run, shared drive is also created.
If the business process currently run is not the business process of first operation in operating system, it is not required to create again
Shared drive, a shared drive can be shared with the business process of first operation in operating system, will can run
Status information generated in journey is write in the existing shared drive.
S102：Judge currently to read process with the presence or absence of status information；
It is understood that the business process currently run is not the business process of first operation in operating system,
The business process currently run is being created after completion status information writes into journey, judge it is current with the presence or absence of status information read into
Journey, it is to be understood that if existence information reads process, may indicate that in the presence of other business process being currently running, should
Target service process can share a status information with the business process that the others are currently running and read process, completion status letter
The reading of breath.Wherein, it is the status information reading process for the shared drive that the status information, which reads process,.
S103：When judging to be not present, creation state information reads process；
It is emphasized that when judging that there is currently no status information reads process, the business process currently run
Meeting creation state information reads process, to ensure that the business process currently run writes the normal of the status information of the shared drive
Read, further, ensure the reading of the status information of the business process for sharing the shared drive of follow-up operation.
In embodiments of the present invention, without one status information reading as finger daemon of operation in os starting
Process, to complete the reading of the status information stored in shared drive, any business process may determine that currently whether deposit
Read process in status information, and when judging that non-existence information reads process, can active creation state information read into
Journey, you can with realize any business process can creation state information read process, and need not take notice of that the operation of business process is suitable
Sequence, it is further ensured that the status information for being capable of existence anduniquess in the operating system when there is business process operation reads process, with energy
Enough read the status information in the shared drive.
S104：Journey is write into by the status information status information that business process that this currently runs generates is written to this and be total to
Enjoy in internal memory；
It should be noted that the business process of each operation creates a corresponding status information and writes into journey, will
In the status information write-in shared drive that business process generates in the process of running.The status information of the establishment writes into journey by business
The status information that process generates in the process of running is written in shared drive.Wherein, for the status information in shared drive
For, typically first write and first read, read after rear write-in.
In a kind of specific implementation, a shared drive, and the plurality of industry are shared when multiple business process be present
In the process of running, that is, the business process of the multiple operations write state information into shared drive be present in business process, share in
Time correlation of the order of the status information of write-in only with status information write-in is stored, also, the reading of status information is also only
With the time correlation of status information write-in.In addition, the label information of corresponding business process is all included in per bar state information, with
Which business process derived from for distinguishing status information.
S105：The status information that process or establishment are read by the status information currently existed reads process from the shared drive
Read status information, and store into default memory space.
It is understood that when there is currently status information reading process, the status information currently existed can be used
Reading process, the read status information from shared drive, and the status information of the reading is stored in default memory space.When
When there is currently no status information reading process, the status information that the business process currently run can be used to create reads process, from
Read status information in shared drive, and the status information of reading is stored in default memory space.
Using the embodiment of the present invention, the business process establishment currently run writes into journey for the status information of shared drive,
The shared drive is created by the business process of first operation；Judge currently to read process with the presence or absence of status information；Judging
In the absence of when, creation state information read process；Journey is write into by the shape of the business process generation currently run by the status information
State information is written in the shared drive；By the status information that currently exists read process or establishment status information read process from
Read status information in the shared drive, and store into default memory space.
It can be seen that when multiple business process in operating system be present and need to use same shared drive, it is shared for this
The status information of internal memory, which reads process, to be created by the business process of any operation, without taking notice of that the startup of each business process is suitable
Sequence, it can guarantee that in operating system that status information corresponding to a status information reading process and each business process being present is write into
Journey, avoid missing status information, preferably to ensure the full storage of status information.
In a kind of specific implementation, before the business process establishment shared drive of this first operation, further create
Have a semaphore；
It is described journey write into by the status information status information that business process that this currently runs generates is written to this be total to
Enjoy in internal memory, including：
Journey is write into after the famous semaphore is obtained by the status information, the state that will be generated in business process running
Information is written in the shared drive, and after the completion of write-in, discharges the famous semaphore；
The status information that process or establishment are read by the status information currently existed reads process from the shared drive
Read status information, including：
The status information that process or the establishment are read by the status information currently existed reads process in the acquisition famous signal
After amount, the read status information from the shared drive, and after the completion of reading, discharge the famous semaphore.
It should be noted that first business process run in operating system, before shared drive is created, also needs to create
Famous semaphore, it is to be understood that status information write into journey by status information write-in shared drive neutral condition information read into
Journey read status information from shared drive, the famous semaphore is all relied on, creates famous semaphore, to ensure status information
Write-in and reading.Create after completing shared drive, also need to carry out initialization process to shared drive, initialize the shared drive
Can be status information write-in allocation space and obtain the relevant information of the shared drive, such as the initial address of the shared drive
Deng as shown in Figure 2 a.Other, generally, created when being run except the business process of first operation in the operating system
The business process for sharing the shared drive of successfully outer, follow-up operation can be created in the famous signal of establishment by having a semaphore
During amount, the operating system can be informed in the business process shared drive by way of returning to famous semaphore and mistake being present
Famous semaphore be present, the business process creates famous semaphore failure, and as shown in Figure 2 a, follow-up business process creates shared
Internal memory can also fail.Wherein, as shown in Figure 2 b, business process when existence information needs to write shared drive, enter by business
Status information corresponding to journey, which writes into journey, can directly obtain famous semaphore, and after famous semaphore success is obtained, be based on
The famous semaphore writes the status information generated in the business process running in shared drive, is write in status information
After the completion of, discharge famous semaphore.
As shown in Figure 2 b, when the business process of operation, stateful information needs to write in the shared drive in the process of running
When, status information corresponding to the business process of the operation writes into journey and obtains famous semaphore, and will be certainly based on the famous semaphore
In the status information write-in shared drive that body generates in the process of running, and after the completion of write-in, discharge the famous semaphore.When
When needing to read the status information stored in the shared drive, the status information reads process and obtains the famous semaphore, when this
After status information reading process obtains the successfully famous semaphore, based on the famous semaphore, reading state is believed from the shared drive
Breath, and after the completion of reading, discharge the famous semaphore.
Wherein, the status information read process can the periodically read status information from the shared drive.
When multiple status informations be present and write into journey, only obtain famous semaphore status information write into journey can be to altogether
Internal memory write state information is enjoyed, only after the famous semaphore is released, other status informations write into journey or status information is read
Process can just get the famous semaphore.It is understood that by obtaining and discharging famous semaphore, each shape is realized
Mutual exclusion between state information writing/reading process.I.e. when there is a status information to write into journey write state information into shared drive,
Other status informations write into journey and status information reads the status information that process cannot write/read in the shared drive.Similarly,
When status information reads process read status information from shared drive, each status information writes into journey all can not be to shared drive
Middle write state information.
In a kind of specific implementation, in view of the situation of at least two business process while operation occurs, i.e., at least
Two business process need into shared drive write state information, for example：Business process 1 and business process 2 be present, and
The status information that there is currently is read process and created by business process 1.When business process 1 exits, the shape that is created by business process 1
State information, which reads process, can also exit, but now, business process 2 still in operation, i.e., still has the state letter of write-in shared drive
Breath needs to read, if creation state information reads process not in time, Partial State Information just has the danger of loss.In order to avoid going out
Present condition information lose situation, each business process currently run in the process of running, all can real-time judge it is current
Process is read with the presence or absence of status information, when judging that there is currently no status information reads process, creation state information reads process.
That is, the meeting real-time judge of business process 2 reads process with the presence or absence of status information, cause when business process 1 exits by business
When the status information reading process that process 1 creates exits, business process 2 can interpolate that out that there is currently no status information reads process,
Process is read so as to create a status information, to continue to complete the read operation of status information.
In a kind of specific implementation, the shared drive includes status information buffer area and shared drive information is deposited
Storage area, the status information buffer area are used for storage state information, and the shared drive information storage area is used to store the status information
The space hold label information of buffer area；
Journey is write into by the status information status information that the business process that currently runs generates is written to this and shared
In internal memory, including：
Journey is write into by the status information status information that the business process that this currently runs generates is written to state letter
Cease buffer area；
And change the space hold label information；
The status information that process or establishment are read by the status information currently existed reads process from the shared drive
Read status information, including：
The status information that process or the establishment are read by the status information currently existed reads process, is cached from the status information
Read cached status information in area；
And change the space hold label information.
It is emphasized that for the ease of the management of the shared drive, it is divided into buffer status information again in the shared drive
Status information buffer area, and store the status information buffer area space hold label information shared drive information storage
Area.Write-in and reading for status information are carried out in status information buffer area, in write-in with reading the same of the status information
When, change the space hold label information of the status information buffer area in the shared drive information storage area.Such as, when state is believed
The status information that caches is read completion in breath buffer area, and this is read space shared by the status information of completion then can be by
Labeled as that can cover, i.e., the space can be used for the other status informations newly write of caching.When a certain spatial cache enters state
Information, the space can then be marked as covering, i.e., the space cannot cache other status informations newly write again,
Until after the status information that the space is cached is read, the space could be utilized again.Wherein, the status information buffer area
Can be with " LOG BUFFER " represent that the shared drive information storage area can use " LOG INFO " expressions.
In a kind of specific implementation, the shared drive information storage area is also stored with reads process on status information
Identification information；
The judgement currently reads process with the presence or absence of status information, including：
Judge whether the identification information is predetermined value；
When the identification information is predetermined value, then judge that existence information reads process；When the identification information is not pre-
During definite value, then judge that status information, which is not present, reads process.
It is understood that the shared drive information storage area is also stored with the mark letter that process is read on status information
Breath, the shared drive are that (including business process, status information write into journey and shape for the process that is directed in the operating system and thread
State information reads process) visible, the business process of the operation, the identification information can be read in real time, according to the identification information
It then may determine that and currently read process with the presence or absence of status information, wherein, when the identification information is predetermined value, then judge exist
Status information reads process；When the identification information is not predetermined value, then judge that status information, which is not present, reads process.
In a kind of specific implementation, after the creation state information reading process, the embodiment of the present invention is provided
The storage method of status information a kind of can also include：The identification information is revised as the predetermined value；
A kind of storage method for status information that the embodiment of the present invention is provided can also include：
The status information of the establishment reads process before the business process currently run with this exits, and the identification information is changed
For the non-predetermined value.
It should be noted that when non-existence information reads process, what the shared drive information storage area was stored, close
The identification information that process is read in status information is non-predetermined value, and when existence information reads process, the identification information is predetermined
Value.It should be understood that after creation state information reading process, the business process currently run can be by the identification information from non-
Predetermined value is revised as predetermined value.Similarly, the status information read process can before the business process currently run with this exits,
The identification information is revised as the non-predetermined value.
In a kind of specific implementation, the default memory space includes predetermined quantity storage subspace；
The status information that process or establishment are read by the status information currently existed reads process from the shared drive
Read status information, and be stored in default memory space, including：
The status information reading process that process or establishment are read by the status information currently existed is read from the shared drive
Status information；
According to storage order corresponding to the storage subspace, the status information read is stored empty to corresponding storage
Between.
It is understood that read process by status information after read status information, can read this from shared drive
Status information be stored in default memory space, to realize monitoring to each business process running, and realize to
Family is visible, and user can enter according to the status information (each business process) being stored in default memory space to each business
Journey or operating system carry out Analysis on Fault Diagnosis.
Wherein, the default memory space includes predetermined quantity storage subspace, the predetermined quantity storage subspace
Storage location sequencing be present, the status information read is first stored in storage location is forward to be come first and deposit
Store up in subspace, after the forward storage subspace for coming first of storage location is filled with, be stored in next storage location
Forward storage subspace, until after all storage subspaces are all taken, since first stores subspace, carry out
Covering is deleted, and stores the status information newly read.Wherein, the memory capacity of the storage subspace can independently be set by user
Put, can also be by equipment default setting.
In addition, in a kind of specific implementation, the storage subspace can be shown in the form of journal file, can be adopted
It is named that (e.g., predetermined quantity 5, journal file are entitled to journal file with name plus the mode for counting index value：Daily record text
Part 1, journal file 2, journal file 3, journal file 4 and journal file 5).When storing read status information, first store
In journal file 1, after journal file 1 is filled with, it is stored in journal file 2, by that analogy, when journal file 5 is also filled with
Afterwards, covering can be proceeded by from journal file 1 or is deleted, stores the status information newly read again.It is other, can be with
Journal file 1 is directly deleted, then, journal file 2 journal file 1 is revised as respectively, journal file 3 is revised as to daily record text
Part 2, journal file 4 are revised as journal file 3, journal file 5 is revised as journal file 4, finally, re-create journal file 5,
The status information that can so ensure to be stored in the maximum file of index value is newest status information forever.
