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.

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.

Provided are a method, system, and article of manufacture for a common configuration framework for applications to configure database objects and resources. configuration interfaces are maintained for a plurality of different database types, wherein each configuration interface implements a database configuration operation with respect to a database of one database type. A configuration request is received from an application indicating a database type, database name, and a database configuration operation. A determination is made of one of the configuration interfaces for the requested database type to implement the requested configuration operation with respect to the database having the database name. The determined configuration interface is invoked with the requested database name to perform the requested configuration operation with respect to the database name.

An apparatus and system are disclosed for asymmetric security in data communications between two or more nodes. Asymmetric security within data communications refers to sending and receiving messages at different security levels. The apparatus includes a receiving module, a transmission module, and a communication module. The receiving module receives a first message at a first security level from a first node. A security level may be defined by implementation of one or more security features, including encryption, digital signatures, and/or other security features. The transmission module transmits a second message at a second security level to the first node in response to receiving the first message. The first and second messages may be communicated during a single communication session. The communication module communicates the second security level to the first node. The communication may be directly between two nodes or may occur via a broker or other intermediate node.

A method for hosting one or more versions of a service using a service proxy includes specifying an interface definition of a service which defines and uniquely identifies an interface version for the service, and an implementation definition of the service which uniquely identifies an implementation version for the service; generating one or more service proxies each representing an interface version of a service; providing a proxy configuration that contains entries for a plurality of service implementation versions, wherein each proxy utilizes the proxy configuration to access a certain one or more of the implementation versions which share the same or a compatible interface version of a service, and wherein the proxy configuration contains attributes that include information about each of the implementation versions; and wherein the proxy dynamically selects one of the implementation versions in the proxy configuration to route one or more client service requests to based on the attributes.

An apparatus, system, and method are disclosed for selective, end-to-end message level security. The apparatus includes a message class definition module, a security module, and a messaging module. The message class definition module identifies a predetermined message class of an internode message. The security module applies security to the message at an application layer. The security that is applied to the message corresponds to a security level, which depends on the message class of the message. The security may include encryption, authentication, and/or other security features. The messaging module communicates the message between a first node and a second node. A third node, such as a broker, may be interposed between the first and second nodes, in which case the security of the message is preserved at the third node.

A method, system, and computer program code for integrating components with different interfaces in an enterprise application integration environment. When an enterprise application is assembled, a user may try to wire a component to another component in the enterprise. However, if the reference on the source component does not match the interface on the target component, the components cannot be wired together. In this situation, the user is prompted to introduce an interface mediation component between the source and target application components. The mediation component comprises an interface matching the reference on the source component and a reference matching the interface on the target component. The mediation component mediates the different interfaces at runtime by binding an operation in the source component to an operation in the target component, and performing a parameter mediation of parameters in the first operation to parameters in the second operation.
