20080235569 | AUTO-GENERATION AND AUTO-VERSIONING OF A MULTI-SOURCED DYNAMIC DOCUMENT - A computer-implementable method, system and computer media for auto-generating and auto-versioning a dynamic document are presented. In a preferred embodiment, the computer-implementable method includes populating a dynamic document with content from multiple sources. The dynamic document is then version named in accordance with a nomenclature rule that identifies a source and version of content from the multiple sources. In response to a content from one or more of the multiple sources changing at a source, the dynamic document is updated with updated content, and a version name of the dynamic document is updated to reflect the updated content. | 09-25-2008 |
20110099265 | DEFINING ENFORCING AND GOVERNING PERFORMANCE GOALS OF A DISTRIBUTED CACHING INFRASTRUCTURE - 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. | 04-28-2011 |
20110153770 | DYNAMIC STRUCTURAL MANAGEMENT OF A DISTRIBUTED CACHING INFRASTRUCTURE - Embodiments of the present invention provide a method, system and computer program product for the dynamic structural management of an n-Tier distributed caching infrastructure. In an embodiment of the invention, a method of dynamic structural management of an n-Tier distributed caching infrastructure includes establishing a communicative connection to a plurality of cache servers arranged in respective tier nodes in an n-Tier cache, collecting performance metrics for each of the cache servers in the respective tier nodes of the n-Tier cache, identifying a characteristic of a specific cache resource in a corresponding one of the tier nodes of the n-Tier crossing a threshold, and dynamically structuring a set of cache resources including the specific cache resource to account for the identified characteristic. | 06-23-2011 |
20110161598 | DUAL TIMEOUT CACHING - 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. | 06-30-2011 |

20080282039 | METHOD AND SYSTEM FOR PROACTIVELY MONITORING THE COHERENCY OF A DISTRIBUTED CACHE - A method of proactively monitoring the coherency of a distributed cache. A cache comparison utility selects a set of cache keys from a replica cache connected to a main cache via a network. The cache comparison utility selects a first cache key from the set of cache keys and fetches a first cache value from the replica cache that corresponds to the first cache key. The cache comparison utility generates a first checksum value corresponding to the first cache value and the first cache key and stores the first checksum value in a first checksum table. The cache comparison utility creates a first total checksum value that corresponds to the first checksum table and compares the first total checksum value with multiple total checksum values that correspond to the main cache and one or more additional replica caches, thereby identifying replica caches that are not identical to the main cache. | 11-13-2008 |
20090307304 | Method for Server Side Aggregation of Asynchronous, Context - Sensitive Request Operations in an Application Server Environment - Process, apparatus and program product for processing a request at an application server are provided. The process includes initiating one or more asynchronous operations in response to the request received by the application server. The process further includes generating a response content that includes one or more placeholders. Thereafter, one or more placeholders mark a location of content corresponding to each of the one or more asynchronous operations. The process further includes aggregating content received from a completed asynchronous operation by filling the content in the corresponding placeholder. The process further includes sending a partial response content with content up to the first unfilled placeholder. | 12-10-2009 |
20100005266 | Technique for estimating the size of an in-memory cache - 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. | 01-07-2010 |
