摘要:
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.
摘要:
A method and apparatus for dynamic adaptation of a configuration to a system environment. An embodiment of a method includes obtaining system information for a system. The system information is stored in a memory. A setting of an abstract configuration for the system is resolved, with the resolution of the setting being based at least in part on the system information.
摘要:
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.
摘要:
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.
摘要:
A system and method for monitoring internal operation of a virtual machine (“VM”). The VM is operated to interpret and execute a program. During operation of the VM, status information regarding internal operation of the VM is stored to an internal memory buffer. The status information is subsequently extracted from the internal memory buffer during operation of the VM to monitor internal operation of the VM from a vantage point external to the VM.
摘要:
A system and a corresponding method for monitoring and controlling server nodes in a clustered environment. The cluster includes a first instance and a second instance, each of the first and second instances including a number of server nodes. Each instance executes a control logic to start the instance by initiating a launch logic for each of the server nodes in the cluster. When initiated, the launch logic is configured to load a virtual machine in each respective server node and execute Java processes in the virtual machine. The system further includes a communication interface coupled between the launch logic and the control logic to enable exchange of information between the Java processes and the control logic. The launch logic is configured to obtain information regarding a status of each of the Java processes running in the virtual machine and enable the control logic to access the status information via the communication interface.
摘要:
A cluster of architecture having a star topology with the central services node at its center. Application server instances are organized in a star topology with the central services node at its center. The central services node may include services such as a messaging server for interinstance cluster communications. A locking server may also be provided to provide cluster wide locking to facilitate changes and updates within the cluster. A database may also be shared by all instances in the cluster, thereby reducing the need for data replication. In one embodiment, the message server has no persistent state. In such an embodiment, if the message server fails, it can merely be restarted without any state recovery requirement.
