when they are being used, except periodically when they are connected to their host computers, either physically or through a computer network During these periods of disconnection, the mobile host may remain in operation The user of the mobile host may issue queries and updates on data that reside or are cached locally This situation creates several problems, in particular: Recoverability: Updates entered on a disconnected machine may be lost if the mobile host experiences a catastrophic failure Since the mobile host represents a single point of failure, stable storage cannot be simulated well Consistency: Locally cached data may become out of date, but the mobile host cannot discover this situation until it is reconnected Likewise, updates occurring in the mobile host cannot be propagated until reconnection occurs We explored the consistency problem in 19, where we discussed network partitioning, and we elaborate on it here In wired distributed systems, partitioning is considered to be a failure mode; in mobile computing, partitioning via disconnection is part of the normal mode of operation It is therefore necessary to allow data access to proceed despite partitioning, even at the risk of some loss of consistency For data updated by only the mobile host, it is a simple matter to propagate the updates when the mobile host reconnects However, if the mobile host caches readonly copies of data that may be updated by other computers, the cached data may become inconsistent When the mobile host is connected, it can be sent invalidation reports that inform it of out-of-date cache entries However, when the mobile host is disconnected, it may miss an invalidation report A simple solution to this problem is to invalidate the entire cache on reconnection, but such an extreme solution is highly costly Several caching schemes are cited in the bibliographical notes If updates can occur at both the mobile host and elsewhere, detecting con icting updates is more dif cult Version-numbering-based schemes allow updates of shared les from disconnected hosts These schemes do not guarantee that the updates will be consistent Rather, they guarantee that, if two hosts independently update the same version of a document, the clash will be detected eventually, when the hosts exchange information either directly or through a common host The version-vector scheme detects inconsistencies when copies of a document are independently updated This scheme allows copies of a document to be stored at multiple hosts Although we use the term document, the scheme can be applied to any other data items, such as tuples of a relation The basic idea is for each host i to store, with its copy of each document d, a version vector that is, a set of version numbers {Vd,i [j]}, with one entry for each other host j on which the document could potentially be updated When a host i updates a document d, it increments the version number Vd,i [i] by one Whenever two hosts i and j connect with each other, they exchange updated documents, so that both obtain new versions of the documents However, before exchanging documents, the hosts have to discover whether the copies are consistent: 1 If the version vectors are the same on both hosts that is, for each k, Vd,i [k] = Vd,j [k] then the copies of document d are identical. asp.net core barcode generator How to easily implement QRCoder in ASP .

Create, edit, or visualize Barcode using the ASP . NET Core Barcode Generator Control. 2 If, for each k, Vd,i [k] Vd,j [k] and the version vectors are not identical, then the copy of document d at host i is older than the one at host j That is, the copy of document d at host j was obtained by one or more modi cations of the copy of the document at host i Host i replaces its copy of d, as well as its copy of the version vector for d, with the copies from host j 3 If there is a pair of hosts k and m such that Vd,i [k] < Vd,j [k] and Vd,i [m] > Vd,j [m], then the copies are inconsistent; that is, the copy of d at i contains updates performed by host k that have not been propagated to host j, and, similarly, the copy of d at j contains updates performed by host m that have not been propagated to host i Then, the copies of d are inconsistent, since two or more updates have been performed on d independently Manual intervention may be required to merge the updates The version-vector scheme was initially designed to deal with failures in distributed le systems The scheme gained importance because mobile computers often store copies of les that are also present on server systems, in effect constituting a distributed le system that is often disconnected Another application of the scheme is in groupware systems, where hosts are connected periodically, rather than continuously, and must exchange updated documents The version-vector scheme also has applications in replicated databases The version-vector scheme, however, fails to address the most dif cult and most important issue arising from updates to shared data the reconciliation of inconsistent copies of data Many applications can perform reconciliation automatically by executing in each computer those operations that had performed updates on remote computers during the period of disconnection This solution works if update operations commute that is, they generate the same result, regardless of the order in which they are executed Alternative techniques may be available in certain applications; in the worst case, however, it must be left to the users to resolve the inconsistencies Dealing with such inconsistency automatically, and assisting users in resolving inconsistencies that cannot be handled automatically, remains an area of research Another weakness is that the version-vector scheme requires substantial communication between a reconnecting mobile host and that host s mobile support station Consistency checks can be delayed until the data are needed, although this delay may increase the overall inconsistency of the database The potential for disconnection and the cost of wireless communication limit the practicality of transaction-processing techniques discussed in 19 for distributed systems Often, it is preferable to let users prepare transactions on mobile hosts, but to require that, instead of executing the transactions locally, they submit transactions to a server for execution Transactions that span more than one computer and that include a mobile host face long-term blocking during transaction commit, unless disconnectivity is rare or predictable. asp.net core qr code generator QR Code Generator in ASP .
