Abstract: Adaptive optimization of second level cache is disclosed. In an example embodiment, a system includes a database server and an enterprise application server, which includes an enterprise application execution module, a first level cache, a second level cache, and a cache optimizer. The enterprise application server iteratively executes an executable module, which causes receiving entity data from a database, with a plurality of different attributes, storing the entity data in a first level cache, and accessing an attribute in the entity data from the first level cache. The enterprise application server collects statistical data representing a quantity of accesses of attributes, determines an attribute to omit from a second level cache based on the statistical data, transfers a subset of the entity data from the first level cache, and stores, in the second level cache, the subset of the entity data with the at least one attribute omitted.

Abstract: A system and method of flexible holding storage during messaging includes determining one or more properties of a message, the message to be stored in a holding storage area of a messaging system, determining status of one or more candidate holding storage devices, determining one or more storage selection rules, adjusting the one or more storage selection rules based on information associated with the status of the one or more candidate holding storage devices, and selecting a holding storage device for the message from the candidate holding storage devices based on the adjusted storage selection rules and information associated with the properties of the message. The one or more storage selection rules express preferences among the one or more candidate holding storage devices. In some examples, the system and method further include sending the message to the selected holding storage device.

Abstract: A system and method of server selection using competitive evaluation includes receiving a service request at an arbiter running on a computing device, determining whether the service request is associated with a preferred server, and forwarding the service request to the preferred server when the service request is associated with the preferred server. When the service request is not associated with the preferred server, the method further includes using the arbiter to coordinate a competitive evaluation among a plurality of active servers, selecting as the preferred server a first one of the active servers that completes processing of the service request first, and associating the preferred server with the service request. The method further includes receiving a response to the service request from the preferred server and returning the response to a client. The service request is received from the client.

Abstract translation: 使用竞争性评估的服务器选择的系统和方法包括在运行在计算设备上的仲裁器处接收服务请求，确定服务请求是否与优选服务器相关联，以及当服务请求是服务请求时将服务请求转发到优选服务器 与首选服务器相关联。 当服务请求不与优选服务器相关联时，该方法还包括使用仲裁器来协调多个活动服务器之间的竞争性评估，选择完成服务请求处理的第一个活动服务器作为优选服务器 首先，并将首选服务器与服务请求相关联。 该方法还包括从优选服务器接收对服务请求的响应并将响应返回给客户端。 从客户端收到服务请求。

Abstract: A method performed by a computing system includes, with the computing system, caching, within a cache module of the computing system, a resource request result from a web service, storing, by the computing system, metadata associated with the resource request result, the metadata including a set of entities used to produce the resource request result, wherein the metadata further includes a version of each entity associated with the resource request result, with the computing system, in response to determining that an entity from the set of entities has changed since the resource request result was cached, invalidating the cached resource request result, wherein determining that the entity from the set of entities has changed comprises determining that a version of the entity has changed.

Abstract: A method includes, with a computing system, receiving a first resource request for a Representational State Transfer (REST) web service, in response to determining that a resource request result of the first resource request is not cached, passing the first resource request to the REST web service, receiving from the REST web service, the resource request result and metadata associated with the resource request result, the metadata indicating a set of entities associated with the resource request result, caching the result and storing the metadata with the cached result, receiving a second resource request, the second resource request being the same as the first resource request, in response to determining that an entity from the set of entities has changed since the resource request result was cached, invalidating the cached resource request result and passing the first resource request to the REST web service.

Abstract: Systems and methods are disclosed for replicating data. An example method includes receiving at a server a current data index and current data. The server is coupled to a first node and a second node, and the current data is responsive to a request from a client. The method also includes replicating the current data and the current data index to the second node. The method further includes receiving at the server a heartbeat message including the current data index and a client identifier. The heartbeat message is from the second node, and the client identifier identifies the client. The method also includes in response to receiving the heartbeat message, sending a notification indicating that the current data has been replicated to the second node to a load balancer.
