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: A method and apparatus for virtualized and adaptive configuration. An embodiment of a method includes generating a system configuration. The configuration includes a setting, with the setting having an abstract value to be resolved based at least in part on a characteristic of a system. The configuration is installed in a recipient system, and a value is resolved for the setting based at least in part on a characteristic of the recipient system.

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: Embodiments of the invention are generally directed to a system and method for an application server architecture having a common connection manager for at least two heterogeneous application server software suites. One of the software suites is a standards-based application server software suite having a plurality of worker nodes. In one embodiment, the plurality of worker nodes share code and data that is stored in a shared memory.

Abstract: A connection manager includes a dispatcher that dispatches requests to two or more heterogeneous software suites. The connection manager receives client requests and dispatches the request to either of the software suites coupled by a request/response shared memory to the connection manager.

Abstract: A system and method to debug a thread without affecting other threads in a virtual machine. A virtual machine (VM) may execute a thread subject to debugging and another thread. An interface to the VM permits only debugging command that are specific to the thread subject to debugging to affect the VM.

Abstract: A software toolset includes a number of software modules that handle control and data communication within a web application server instance. An application programmatic interface (API) provides a common interface to communicate with the software modules in the toolset.

Abstract: A method and a corresponding system for managing communication between multiple instances contained within a clustered environment. The method includes generating a packet to be transmitted from a non-Java-based server node to a Java-based server node. The non-Java-based server node specifies in a header of the packet [1] a destination server node and [2] information to indicate that the packet originated from the non-Java-based server node. The method further includes forwarding the packet from the non-Java-based server node to an intermediate server. Once the intermediate server receives the packet, the intermediate server examines the header of the packet and forwards the packet to the Java-based server node based on the destination information provided in the header of the packet.

Abstract: A system and method for integrating different virtual machines (“VMs”). A first VM is loaded into an Application Server (“AS”) instance. The first VM includes standard features accessible through a standard native interface. A second VM is loaded into the AS instance including the standard features and extended features. The standard features provided by the second VM are accessed by native platform entities through a standardized native interface. The extended features provided by the second VM are accessed by the native platform entities through an adaptation interface.

Abstract: A system and method to monitor application servers using shared monitoring memory. An application server includes worker nodes having Java virtual machines to process work requests received by the application server. Status information is generated for each of the worker nodes while processing the work requests. The status information for each of the worker nodes is then stored into the shared monitoring memory while the worker nodes operate.

Abstract: A system and method to monitor a virtual machine VM. The VM executes one or more applications. During executing of the one or more applications, local objects are created and stored within an internal heap maintained by the VM. Status data of the internal heap is published to monitoring memory external to the VM.

Abstract: A system and method to monitor client sessions within a Java virtual machine. Client sessions are established within an application server instance to store session context data for each of the client sessions during the client sessions. At least two Java virtual machines are operated within the application server instance to service client requests received from clients associated with each of the client sessions. Status information about each of the client sessions is reported into shared memory external to the Java virtual machines to monitor each of the client sessions during operation of the Java virtual machines.

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: A connection manager includes a dispatcher that dispatches requests to worker nodes in an application server. The connection manager receives client requests and dispatches the requests on different channels multiplexed over the same session to worker nodes coupled by a request/response shared memory to the connection manager.

Abstract: A system and method are described for remotely debugging an application server. In one embodiment, a plurality of application servers are organized into groups referred to as “instances.” Each instance may include a group of redundant application servers, one or more debug nodes, and a dispatcher. The dispatcher distributes service requests to each of the application servers in accordance with a load-balancing mechanism. In addition, a central message passing architecture is defined which allows the various instances to communicate with one another. In one embodiment, a debug node is isolated from the load-balancing mechanism. The debug node may also be isolated from the central message passing architecture. A remote node may then debug an application on the debug node, without disrupting processes executing on other application servers in the instance.

Abstract: A cluster manager application program library includes an event handler to communicate an event from an application server instance to which the library is linked to a message server in a cluster of application server instances. The library further includes a notification handler to receive at the application server instance a notification of an event in the cluster from the message server, and a message server communication handler to exchange messages between the application server instance and other application server instances in the cluster via the message server.

Abstract: A system and method are provided for template-based configuration architecture. Configuration information from a first level is inherited. Configuration templates are customized via the inherited configuration information based on usage at a second level. The customized configuration templates are applied to default instances at a third level.
