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.

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.

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.

摘要:
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.

A system for integrating applications in different enterprises separated by firewalls comprises: an input for receiving high level business data from a source application; an encryption engine for encrypting the business data to produce encrypted business data; a queue manager for receiving the encrypted business data and for storing the business data for delivery to a target application; and an output for transmitting the encrypted business data to the target application; wherein the system and the target application are separated by at least one firewall.
