atomicity

Declaring a block of code to be synchronized has two important consequences, generally referred to as atomicity and visibility.

Analysis shows that this protocol guarantees the security, atomicity, accountability and impartiality of network online payment.

The guarantee of atomicity means that either all or none of these operations will occur, hence ensuring overall data integrity.

Rather, it is much more of a cache manager, in that it utilizes the atomicity of transactions to persist objects to a database.

Atomicity A transaction is an atomic unit of work and executes exactly once; either all the work is done or none of it is.

In combination with the corresponding recovery protocols, recovery algorithm guaranteed the atomicity of global transaction failure.

Likewise, operations updating multiple tables can take advantage of transactional atomicity in their changes.

A transactional runtime environment assures atomicity, consistency, isolation, and durability of applications.

The relational databases also include the transaction ACID property (Atomicity, Consistency, Isolation, Durability).

Atomicity means that operations with the database can be grouped together and treated as a single unit.

IBM solidDB implements ACID-compliant (Atomicity, Consistency, Isolation, Durability) in-memory cache to provide data durability.

Each log message contains the required atomicity level within the transaction coordination context.

Log operations can be treated as well as other updates to participate in atomicity.

Savepoints are the perfect mechanism to achieve finer granularity of atomicity within a transaction.

This variant is a compromise between atomicity and cost of transaction overhead.

A distributed transaction will be started to guarantee atomicity across all nodes that are affected by the update.

Atomicity, as a basic transaction property, is implemented in various systems.

Atomicity: Either all steps that are part of the transaction happen or none will happen.

The new model satisfies money and goods atomicity, and is more suitable than the original for the protocol in realistic environment.

Bear in mind that the volatile keyword in Java code only guarantees that a variable is visible: it does not guarantee atomicity.

A distributed transaction will be started to guarantee atomicity across all nodes affected by the update.

CRMs apply atomicity and durability properties to non-transactional resources.

It also uses the log service (Logging) on the log service node, sending log messages with different atomicity levels.

Atomicity ensures that all updates are treated as a single unit and are either all committed or all rolled back.

In this paper, we define a log service with some transactional semantics and concentrate on the atomicity semantics.

Even hardware interrupts will respect the atomicity of machine instructions.

If the atomicity level is none, the log message is written immediately to the permanent log media.

A log operation might not participate in atomicity at all.

The primary concerns in this kind of application are concurrency and atomicity.

The logging server then persists all log messages that require atomicity or semi-atomicity.

Atomicity requires that both withdrawal and deposit should happen in one go, or neither must occur.

The SCA container uses a two phase commit to achieve atomicity when multiple transactional resource managers are used.

More subtle than atomicity failures are visibility failures.

Separating the data and indexes raised issues of consistency and atomicity.

But then you lose the whole purpose of locking and atomicity, which clearly shows the necessity of using the memory constraint.

Listing 6 shows how to use an AtomicReference to restore this last bit of atomicity to our example.

It receives log messages, each of which might require a certain atomicity level.

The code in Listing 2 has visibility failures as well as atomicity failures.

"There is a new granularity, atomicity and a kind of chemistry, " he remarked.

There are additional problems with volatile and the atomicity of 64-bit variables, but this is beyond the scope of this article.

Furthermore, the new method can verify not only the non-repudiation of protocol in static state, but also atomicity in dynamic.
