摘要： A method for securing cached data in an enterprise environment. The method can include processing a request to locate data in a query cache. If the data can be located in the query cache, the data can be retrieved from the query cache. Additionally, at least one encrypted portion of the retrieved data can be decrypted. Finally, the decrypted portion and any remaining unencrypted portion of the retrieved data can be forwarded to a requesting client. By comparison, if the data cannot be located in the query cache, the data can be retrieved from a back-end data source over a computer communications network, and forwarded to the requesting client. Additionally, at least a portion of the retrieved data can be encrypted and both the encrypted portion and any remaining unencrypted portion can be stored in the query cache.

摘要： An object state caching method can include augmenting a compiled object having at least one referenced method with conditional caching logic. The conditional caching logic can be executed in an execution environment to determine whether to execute the referenced method. If the conditional caching logic determines not to execute the referenced method, the execution of the referenced method can be bypassed. Additionally, the stored object state can be retrieved from a communicatively coupled object cache. Finally, the retrieved object state can be forwarded to a requesting process. If, however, the conditional caching logic determines to execute the referenced method, the referenced method can be executed producing the resultant object state, and, the resultant object state can be cached in the coupled object cache.
摘要翻译： 对象状态缓存方法可以包括使用条件缓存逻辑来扩充具有至少一个引用方法的编译对象。 可以在执行环境中执行条件缓存逻辑，以确定是否执行引用的方法。 如果条件缓存逻辑确定不执行引用的方法，则可以绕过引用方法的执行。 另外，可以从通信耦合的对象高速缓存中检索所存储的对象状态。 最后，检索到的对象状态可以转发到请求进程。 然而，如果条件缓存逻辑确定执行引用的方法，则可以执行引用的方法，产生所得到的对象状态，并且所得到的对象状态可以被缓存在所耦合的对象高速缓存中。

摘要： A method of caching contextually variant objects in a common cache. The method can include identifying an object type for a requested object and determining whether the requested object has an object type which is specified among an enumerated set of cacheable object types which can be stored in the common cache. Importantly, each cacheable object type can have an associated context. If the requested object has an object type which is specified among the enumerated set of cacheable object types, a cache key can be computed for the requested object using cache key formulation rules for the associated context. Finally, the requested object can be retrieved from the common cache using the formulated cache key. Notably, in one aspect of the invention, the method also can include the step of invalidating individual objects in the common cache according to corresponding cache policies of associated contexts.
摘要翻译： 在公共缓存中缓存上下文变体对象的方法。 该方法可以包括识别所请求对象的对象类型，并且确定所请求对象是否具有可以存储在公共高速缓存中的可列举的可缓存对象类型集合中指定的对象类型。 重要的是，每个可缓存对象类型可以具有关联的上下文。 如果所请求的对象具有在可列举的可缓存对象类型集合中指定的对象类型，则可以使用用于相关联的上下文的缓存关键字公式规则来针对所请求的对象来计算缓存密钥。 最后，可以使用配置的缓存密钥从公共高速缓存中检索所请求的对象。 值得注意的是，在本发明的一个方面中，该方法还可以包括根据相关联的上下文的相应高速缓存策略使公用高速缓存中的各个对象无效的步骤。

摘要： A method and apparatus route hypertext protocol requests to one of a plurality of application servers, which share a database through a backend database management system. The application servers store session data in the database. Hence, if a subsequent request is routed to a different application server, the session data is available through the backend database management system. One or more web servers perform routing of requests to the application server. When a request is received that is accompanied by a session ID, routing is performed by utilizing a hash function on the session ID. The resulting hash value is mapped to an application server. A hash function on a session ID will always result in the same hash value; therefore, the request will always be routed to the same application server. However, if an application server is non-functional, a new hash based on the previous hash is computed until a functional application server is selected.

摘要： A distributed cache management system that minimizes invalid cache notification events is provided. A cache management system in a sending device processes outgoing cache notification events by adding information about the source server's clock. A cache management system in the receiving device then uses this information to adjust event information once the event is received.

摘要： In a method and system for monitoring events occurring at respective servers of a configuration of nodes, a first server located at a first node receives information from a messaging system pertaining to events at servers located at other nodes. The messaging system usefully comprises a highly available (HA) bulletin board or the like. When the first server receives a start event notification pertaining to a second server located at a second node, a direct communication path is established between the first and second servers. The first server identifies events in the second server that affect or are of interest to services of the first server. The first server then registers with the second server, to receive notification through the direct communication path when respective identified events occur.

摘要： An apparatus, system, and storage medium that, in an embodiment, determine the classes that are needed during a first invocation of an application and preload those classes during a subsequent invocation of the application. In various embodiments, the classes may be preloaded if they are within a specified package, if they were needed greater than a threshold number of times, if the class path did not change between the first invocation and the subsequent invocation, or if the jar files the contain the classes are in a class path. In this way, an embodiment of the invention may increase the performance of class preloading.
