摘要:
A system has a repository that stores a plurality of events. Each event requests to utilize one or more functions in a component. An event sequencing module analyzes an event sequencing key of the event if the event requests a function having a component definition that includes an event sequence qualifier. The event sequencing module grants a lock to the event for the function if no other event having the same value for the event sequencing key has the lock for the function. The event sequencing module prevents the event from being processed if another event having the same value for the event sequencing key has the lock for the function. The event sequencing key is composed of one or more object attributes. The system has a worker server that receives the event, if the event obtains the lock, and processes the function requested by the event.

A computer program product is disclosed. The computer program product includes a computer useable medium that has a computer readable program. The computer readable program when executive on a computer causes the computer to receive a request from a component to invoke a function. Further, the computer readable program, when executed on a computer, causes the computer to asynchronously perform the function according to the request. In addition, the computer readable program, when executed on a computer, causes the computer to provide, to one or more programs, an indication that the function has completed work according to the request.
摘要:
A system and method for providing Quality-of-Service (QoS) functions to concurrent event-processing applications in a multi-processing database environment are described. The system includes an Event-Listener interface for determining the QoS functions applicable to the events being processed and an Event-Service interface for invoking the determined QoS functions. The Event-Service interface loads, initializes and activates the QoS functions. The QoS functions are based on service definitions. The Event-Service interface further initializes the service providers and sends the events that need QoS support to the respective service providers for processing. The QoS functions include the services commonly needed in a clustered event-processing database system like Event-Sequencing, Event-Isolation, High-Availability, Event-Filtering and Flow-Control. Other QoS functions might be added to the database system using the same interfaces provided by the invention.
摘要:
A computer implemented method, data processing system, and computer program product for providing a generic sequencing service for ordering processing requests in a scalable business integration environment. When a request is received at a sequencing component, the operation specified in the request is identified. A determination is then made as to whether to sequence the operation according to a sequencing specification. If the operation is to be sequenced, key information of the operation is classified according to the sequencing specification. A lock on the request is then requested using the operation and the key information. Responsive to the lock being granted, a determination is then made as to whether the request is synchronous or asynchronous. If the request is synchronous, the target service component is invoked synchronously. If the request is asynchronous, the target service component is invoked asynchronously.

A generic lock manager service is provided which allows locks and lock requests to be recovered across system failures and restarts. When a lock request that includes a request to isolate a particular data object is received, the lock manager service examines a lock request queue to determine if the queue contains a second lock request for the data object specified in the lock request. If no second lock request is present, a sequence identifier is assigned to the lock request indicating a lock request processing order for the data object specified in the lock request, and the lock request is persisted in a persistent storage. If a second lock request is present, a maximum sequence identifier of all lock requests directed to the data object is identified. The next higher sequence identifier is assigned to the lock request and the lock request is also persisted in a persistent storage.
摘要:
A system and method for monitoring dynamic scopes in a runtime environment is disclosed. The system and method utilizes an algorithm which may be applied to both synchronous and asynchronous invocations. The method comprises determining an initial scope of a source component, the initial scope being a scope of the source component upon providing a synchronous call to invoke a target component. The scope declaration specified by the target component is determined. A resultant scope present upon invocation of the target component is then determined. The resultant scope is determined based on the initial scope of the source component and the scope declaration specified by the target component. A record is stored in a centralized location identifying the resultant scope, and the target component as a participant in the resultant scope.

摘要:
A computer implemented method, apparatus, and computer usable program code for updating multiple concurrent versions of shared artifact libraries. Shared artifact libraries are associated with a consuming application for establishing shared artifact libraries upon which the consuming application has a dependency for artifacts. A snapshot of the shared artifact libraries associated with the consuming application in an active session is created in response to starting a session. The shared artifact libraries are updated in response to new versions and updates of the shared artifact libraries becoming available. Artifacts are dispensed from the shared artifact libraries to the consuming application based on the snapshot of the session.

Disclosed are a cannabinoid composition and an application of the same in preparing a medicine for treating neurodegenerative diseases, so as to solve the drawbacks of conventional medicines such as serious side effects and degraded therapeutic effect after long-term administration. The cannabinoid composition includes: cannabidiol and cannabigerol, a mass ratio of the cannabidiol to the cannabigerol ranging from 1:1 to 1:10, or from 1:0.3 to 1:0.5, or from 1:0.5 to 1:0.7, or from 1:07 to 1:1. The present disclosure adopts the experimental method of inducing differentiation of fibroblasts to dopaminergic neurons, wherein by observing the cell morphology, quantity, and relative expression level of DA-related factor of the differentiation-induced and cultured fibroblasts, and screening various common cannabinoids and different combinations thereof based on their impacts on inducing differentiation of the fibroblasts into dopaminergic neurons, it was found that the CBD+CBG combination offered an optimal effect in improving viability and dopamine-secreting capability of the dopaminergic neuronal cells; besides, the CBD+CBG combination is free of the addictive substance THC, which thus significantly reduces side effects and may be applied to prepare medicines for treating neurodegenerative diseases.
