Below in conjunction with Fig. 1, Fig. 1 does not shut down newer method by a kind of clustered software system that the embodiment of the present application provides
Flow chart.
It specifically includes following steps：
S101：When needing the software systems for cluster to carry out version updating；
S102：The low-load server of preset quantity is chosen according to the business load situation of each server in cluster, and is taken
It builds to obtain pre-updated publication environment；
This step is established under the practical context described in S101, it is intended to according to the business load shape of each server in cluster
Condition chooses to obtain the low-load server of preset quantity, and builds to obtain pre-updated using these low-load servers and issue ring
Border.
Wherein, low-load server described in this step is to be different from existing for high load server, since composition collects
Portfolio handled by each server of group will not be completely the same, and to ensure the redundancy of equipment and performance usually in cluster,
Standby server can be also set, processing of the master server to a large number of services is different from, standby server is not accepted usually pending
Business, but be in standby, to which its processing business can be taken over rapidly when master server goes offline, ensure entire collection
The integrality of group's function.
The above-mentioned effect having due to standby server and corresponding characteristic can be much smaller than though load is unlikely to be 0
Normal master server, therefore the purpose of this step is then to select a certain number of low-loads from all servers reached the standard grade
Server, with build pre-updated issue environment, i.e., do not influence master server execute regular traffic while, these originally not
Version updating operation is first carried out on the low-load server of undertaking business.
S103：It issues and incremental update data file to the pre-updated obtained based on incremental data upgrade technique is installed and issue

Amount update operation has executed after in such a way that whether the newly-increased function of the testing case is realized etc., do not do specific limit herein
It is fixed, it can flexibly be selected suitably to detect and judge item according to actual conditions.
S105：It sets pre-updated publication environment to new actual motion environment, and is newly-built using new actual motion environment
Vertical conversational services provide support, and carry out version more after former actual motion environmentally established conversational services whole
Newly, so that update is not shut down in entire cluster realization.
Pre-updated publication environment after S104 judges that incremental update operation executes meets the normal work requirement of cluster
On the basis of, this step is intended to set the pre-updated publication environment for completing version updating operation to new actual motion environment, and profit
New pending business is accepted with the new actual motion environment.It is waited for simultaneously when environmentally established session takes former actual motion
Version updating is carried out to it after business whole, so that update is not shut down in entire cluster realization.
It should be noted that the former actual motion environment mentioned by this step is to be mainly responsible for undertaking before having and handle industry
Each master server of business is built, i.e., at that time in the case of standby server be different from master server, can also be considered
Belong to non-actual motion environment, and new actual motion environment is then since pre-updated publication environment finishes and meets in version updating
After normal work requires, undertaking and the processing task of new business can be completed, also complies with and the cluster is gradually transition to new version
Purpose, therefore be set to new actual motion environment, in other words, former standby server becomes new master instead at this time
Server.And be formerly used for keeping the server in the former actual motion environment of entire clustering functionality, then it can be established
Version updating is carried out to it after conversational services whole, realizes that entire cluster is put down in a manner of non-stop-machine by updating in batches
Steady transition.
Further, to prevent the server in actual motion environment and non-actual motion environment from occurring mixing phenomenon, also
It can be unloaded from cluster server stored reservoir, and is needing again when carrying out processing business without using certain server
When its processing business, carry to cluster server stored reservoir again.
Based on the above-mentioned technical proposal, a kind of clustered software system provided by the embodiments of the present application does not shut down newer method,
First when needing to carry out version updating, according to the actual traffic load situation selected part low-load service of server in cluster
Device issues environment as pre-updated, and executes version updating operation in the pre-updated issues environment first, and is in height before
The server (former actual motion environment) of load condition still maintains regular traffic until pre-updated publication environment completes version more
It is new and can accept new pending business as new actual motion environment, just can then terminate it is all before business in processing
Version updating is also carried out to itself afterwards, that so far completes entire cluster does not shut down update.The application be different from tradition to it is all
The server of shutdown is carried out at the same time newer mode, it is at least divided into two parts according to actual loading situation, first to low negative
It carries part and carries out pre-updated, expanded again to entire cluster after the completion of update, former business can be kept not interrupt simultaneously so that two
Divide and good can be connected, also eliminate uniformly to be updated unsuccessfully causes Servers-all that can not reach the standard grade in a short time afterwards

In environment；
It is identical as S102, the related content that content can be found in S102 is illustrated, details are not described herein.
S205：Judge whether version number of the pre-updated publication environment before executing incremental update operation changes；
On the basis of S204, this step is primarily based on version number and has tentatively judged whether to version updating.
S206：Judge whether the pre-updated publication environment after incremental update operation executes realizes incremental update data file
The function adjustment brought；
The foundation of this step is that the base of the completed conclusion of version updating can be obtained based on version number in the judging result of S205
On plinth, it is intended to further to judge whether to realize version updating function adjustment purpose as expected.
It should be noted that if when the judgement by S205 or S206 obtains result contrary to expectations, then can pass through
The mode of S204 is repeated to carry out tentative reparation, specifically, due to update failure may caused by influence, sometimes also
The version before update need to be reverted back first when repeating, to ensure newer success rate.Further, it is held if being repeated several times
Expected edition upgrading purpose is still not implemented in row, then can report this error situation, to check whether incremental update data text
There are mistakes for part itself.
S207：Extremely by each server for belonging to pre-updated publication environment for the normal work requirement for meeting cluster again carry
Cluster server stored reservoir；
This step is corresponding with S203, and the pre-updated publication environment established after incremental update operation executes meets cluster
Normal work require on the basis of, before carry to cluster server stored reservoir is to meet necessity needed for subsequent step again
It carries.
S208：It sets pre-updated publication environment to new actual motion environment, and is newly-built using new actual motion environment

As shown in figure 4, having used increment Multi-state data model modification distribution technology, the core of the technology is edition upgrading
The User Activity session of period retains legacy data model simultaneously, can also by delete, replace, it is newly-increased after data model with another
One new version realizes full model update, increases data model of the session then based on update publication newly and carries out system activity.
For arbitrary business data model, miscellaneous editions, such as grid power tune are likely to occur according to business demand variation
Protection act reporting module in degree system needs emergency upgrade since relevant field will be deleted and be increased newly to business demand change,
When the set expression of version is：F={ f1,f2,f3,......,fn(n ＞ 1), and the model of each version uses a kind of field
The form of set indicates that then the business data model of 5 fields is represented by：f0={ a, b, c, d, e }；It is another basic herein
The upper version that there is change is represented by：f1={ a, c, d, e, g }, i.e., the relationship of two versions are represented by：f1=f0-{b}+
{g}.Therefore, as shown in figure 4, the conversational terminal access that connection has been established before upgrading is f0Version, if upgrading starts rear f0Version
Terminal session is continuously connected with, then f0Edition data model still retains；After new model publication, newly-established terminal session is then visited
Ask f1Edition data model；Until all f0The terminal session of version exits the entire update issuing process of completion.
According to the example, f0And f1Both sides relation can also be expressed as f1=(f0-f0)+(f0{ b }+{ g }), that is, upgrading
After publication, legacy data model terminal ceases to be in force automatically after all exiting, and new model is to delete the legacy data model realization after field
A kind of new version full model update publication, is truly realized increment Multi-state data model supports when upgrading publication.
As shown in fig. 5, it is assumed that carry N platform application servers, terminal user pass through direct routing in application service cluster
Mode realize service access.In upgrading publication operation, system manager will select N-2 platforms from server admin pond and answer first
It uses server unloading as pre- publication environment, carries out upgrading publication operation in pre-upgrade server, system business is by pipe at this time
It manages 2 runtime environment servers in pond and the support of legacy data model service is provided.Complete the publication of pre-upgrade server update
And after being verified by upgrading test, pre-upgrade server is mounted to again in server admin pond and unloads original 2 operations
When environment server, tentatively provide new function service and ensure system persistent service at this time.It is serviced when 2 operations later
Device carries out application service generation by Linux rsync tools (a kind of linux system under synchronization means) and pre-upgrade server
Code is synchronous, and is mounted to again in server admin pond, completes the upgrading operation of Servers-all in cluster.In whole process,
