Abstract: A method and system to provide easy access to factories in a naming service. The system receives an indication that a factory is needed by a client. A plurality of resolvers are checked in turn to find the factory indicated. If a resolver that can provide the factory is found, the factory is returned to the client. In one embodiment, resolvers register with a resolver manager that performs the checking in response to a naming operation. Because the resolver manager can access all registered resolvers, access to the factories is independent of a class path of the user.

Abstract: A system and method to monitor worker threads within a Java virtual machine. At least one program is executed on the Java virtual machine to perform a task. A worker thread of the Java virtual machine is assigned to perform the task. Status information for the worker thread is generated and reported into memory external to the Java virtual machine to enable monitoring of the worker thread from external to the Java virtual machine.

Abstract: A system and method to monitor caches of at least one Java virtual machine (“JVM”). A program is operated on the at least one JVM. Objects associated with the program are cached within a local cache of the JVM. Cache status information about the local cache is generated and then the cache status information is reported into memory external to the JVM to enable monitoring of the local cache from external to the JVM.

Abstract: In one embodiment, a centralized cache configuration for the regions of cache of a system is described. As regions of cache may require different resources they therefore may need to be configured differently. The system for providing central cache configuration includes a centralized cache manager to transform information regarding applications, services, etc. into proper cache regions for each application, service, etc. In one embodiment, the size of these regions is based on a relative weight schema.

Abstract: One embodiment of the invention employs techniques for using a message server to route shared object management messages between virtual machines and/or worker nodes. A worker node may include a cache manager, a listener, and a listener registration table. A shared lock is provided to ensure that the object's properties are consistent across the worker nodes.

Abstract: One embodiment of the invention employs techniques for using a message server to route shared object management messages between virtual machines and/or worker nodes to maintain cache coherence. In one embodiment, shared locks and messaging service between worker nodes and/or virtual machines helps to provide this coherency. These messages utilize a message protocol. The protocol includes a hashable object key, a region identifier, and message type.

Abstract: One embodiment of the invention employs techniques for providing isolation for exclusivity of operation. Isolation may exist between different application and/or different threads or virtual machines of the same application. In one embodiment, using a lock helps to ensure that operations are executed exclusive of each other.

Abstract: A system and method to monitor caches of at least one Java virtual machine (“JVM”). A program is operated on the at least one JVM. Objects associated with the program are cached within a local cache of the JVM. Cache status information about the local cache is generated and then the cache status information is reported into memory external to the JVM to enable monitoring of the local cache from external to the JVM.

Abstract: Methods for a treatment of cached objects are described. In one embodiment, an object, associated with an object key, is stored in a first local memory cache associated with a first virtual machine within a first computing system. The object is also stored in a serialized format to a database. The object key is serialized after receiving a notification of successful storage of the object in the database. The serialized key is then sent over a network to a second computing system.

Abstract: Methods for a treatment of cached objects are described. In one embodiment, management of a region of a cache is configured with an eviction policy plug-in and a storage plug-in. The eviction policy plug-in includes code to evict an object that is cached in the region of cache. The storage plug-in includes code to execute a function involving an object manipulation function that gets a first object located within the region of cache, and an attribute manipulation function that gets a specific attribute for the first object from within the region of cache.

Abstract: A system and method of common cache management. Plural VMs each have a cache infrastructure component used by one or more additional components within each VM. An external cache is provided and shared by the components of each of the VMs. In one embodiment, a shared external memory is provided and populated by the VMs in the system with cache state information responsive to caching activity. This permits external monitoring of caching activity in the system.

Abstract: Methods for a treatment of cached objects are described. In one embodiment, management of a region of a cache is configured with an eviction policy plug-in. The eviction policy plug-in includes an eviction timing component and a sorting component, with the eviction timing component including code to implement an eviction timing method, and the eviction timing method to trigger eviction of an object from the region of cache. The sorting component includes code to implement a sorting method to identify an object that is eligible for eviction from said region of cache. The sorting method includes identifying an object for eviction that is cached in the region of cache and that has been used less frequently than other objects that are cached in the region of cache.

Abstract: A system and method to monitor worker threads within a Java virtual machine. At least one program is executed on the Java virtual machine to perform a task. A worker thread of the Java virtual machine is assigned to perform the task. Status information for the worker thread is generated and reported into memory external to the Java virtual machine to enable monitoring of the worker thread from external to the Java virtual machine.

The eviction policy plug-in includes code to evict an object that is cached in the region of cache. The storage plug-in includes code to execute a function involving a group manipulation function that gets each object within a pre-defined group of objects located within the region of cache, each object associated with a key, each key registered with the storage plug-in.
