摘要： Embodiments of the present invention address deficiencies of the art in respect to workload management of backend systems and provide a novel and non-obvious method, system and computer program product for limiting a request rate from a client based on a health state of a server system. In one embodiment of the invention, a computer-implemented method for limiting a request rate from a client based on a health state of a server system that includes monitoring a server system, determining a measure of health of the server system, sending the determined measure of health to a client submitting a request to the server system and receiving a subsequent request from the client that is delayed by a time period, wherein the time period is based at least in part upon the determined measure of health. The computer-implemented method can further include receiving server system CPU utilization, determining an approximate predicted real server response time of a transaction and sending the determined approximate predicted real server response time of a transaction to a client submitting a request to the server system.

摘要： The ability to leverage a publish/subscribe functionality in an application server environment has allowed the storage of cached entries to be stored over multiple clients rather than on a single application server, freeing up valuable resources. However, in this arrangement it is not possible for the originating server to validate shared content originating from client-side storage. The present invention provides a system and method for securing and validating content from asynchronous include request utilizing public key cryptography and hashing functions.

摘要： Embodiments of the present invention provide a method, system and computer program product for dual timer fragment caching. In an embodiment of the invention, a dual timer fragment caching method can include establishing both a soft timeout and also a hard timeout for each fragment in a fragment cache. The method further can include managing the fragment cache by evicting fragments in the fragment cache subsequent to a lapsing of a corresponding hard timeout. The management of the fragment cache also can include responding to multiple requests by multiple requestors for a stale fragment in the fragment cache with a lapsed corresponding soft timeout by returning the stale fragment from the fragment cache to some of the requestors, by retrieving and returning a new form of the stale fragment to others of the requestors, and by replacing the stale fragment in the fragment cache with the new form of the stale fragment with a reset soft timeout and hard timeout.

摘要： A method, system and computer program product for providing high availability to a hybrid application server environment containing non-Java® containers. Each hybrid application server in the cluster includes a Java® container and a non-Java® container hosting Java® and non-Java® applications, respectively. Upon detecting the non-Java® container becoming unavailable (failing), an object, such as an MBean, identifies and deactivates those Java® application(s) that are dependent on the non-Java® application(s) deployed in the unavailable non-Java® container using dependency information stored in an application framework. The deactivated Java® application(s) are marked as being unavailable. A routing agent continues to send requests to those Java® application(s) that are not marked as being unavailable within that hybrid application server containing the unavailable non-Java® container. As a result of not deactivating the entire hybrid application server containing the unavailable non-Java® container, unimpacted applications continue to service requests thereby optimally using the resources.

摘要： This Sampling Object Cache System (“SOCS”) estimates the size of an in-memory heap-based object cache without the need to serialize every object within the cache. SOCS samples objects at a user-determined rate and then computes a “sample size average” for each type of class—whether a top class, type of top class or non top class. Using these sample size averages, a statistically accurate measure of the overall size of the cache is calculated by adding together the total size of the objects in the cache for each class type.

摘要： Embodiments of the present invention provide a method, system and computer program product for enforcing performance goals in an n-Tier distributed caching infrastructure. In an embodiment of the invention, a method of enforcing performance goals in an n-Tier distributed caching infrastructure can include establishing a communicative connection to multiple different cache servers arranged in respective tier nodes in an n-Tier cache. The method also can include collecting performance metrics for each of the cache servers in the respective tier nodes of the n-Tier cache and identifying a cache server amongst the cache servers in respective tier nodes of the n-Tier demonstrating a performance likely to breach at least one term of an SLA. Finally, the method can include applying a remedial measure to the identified cache server.
