In accordance with an embodiment, described herein is a system and method for supporting patching in a multi-tenant application server environment. The system can associate one or more partitions with a tenant, for use by that tenant, wherein a partition is a runtime and administrative subdivision or slice of a domain. A patching process can take advantage of high-availability features provided by an application server clustering environment, to apply patches in a controlled, rolling restart, which maintains a domain's ability to operate without interruption, or with zero downtime. The process can be used to automate complex or long running tasks, including preserving an unpatched or prior version of an application server, application, or other software component for possible rollback, or providing automatic reversion in the event of an unrecoverable error.

System and method for supporting patching in a multitenant application server environment

In accordance with an embodiment, described herein is a system and method for providing support for custom hooks during patching in an application server, enterprise, cloud computing, or other computing environment. A patch orchestration engine generates a patching workflow including a series of steps that apply patches to update one or more targeted nodes in a controlled manner with minimal downtime. Custom hooks provide a flexible mechanism that enables modifying phases of the patching workflow that can be associated with extension points. When an extension, for example an additional Java software code, script or other command, is specified to be run at a particular extension point associated with a particular phase of a patching workflow, the patch orchestration engine causes the extension to be inserted into the patching workflow, for execution during patching of the targeted nodes, to modify that phase of the patching workflow.

System and method for supporting custom hooks during patching in an application server environment

In accordance with an embodiment, described herein are a system and method for partition-scoped patching in an application server environment. A computer environment includes an application server, for example a multitenant application server, that supports the use of one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain. During a partition-scoped rollout of a patch or update, to a resource group or application within a plurality of servers or clusters of servers, the resource group or application can be updated within a targeted partition, using a patch orchestrator and partition lifecycle runtime interface, without affecting the operation of other partitions at those servers or clusters of servers. One or more session handling flags can be used, to enable sessions and/or requests that are associated with the targeted partition, to be handled by a traffic director, during the patching process.

System and method for partition-scoped patching in an application server environment

In accordance with an embodiment, described herein is a system and method for JMX support in an application server environment. An exemplary method can provide, at one or more computers, including an application server environment executing thereon, a plurality of deployable resources which can be used within the application server environment, one or more partitions, a plurality of managed beans, each managed beans being a partition level managed bean or a domain level managed bean, each partition level managed bean originating at an originating partition of the one or more partitions, and a JMX framework comprising an API and a managed bean server. The plurality of managed beans can be registered at the managed bean server, with the partition level managed beans being decorated with an identifier.

System and method for JMX support in a multitenant application server environment

In accordance with an embodiment, described herein are systems and methods for simulating a cloud environment on a physical platform. In an embodiment, a physical assembly is provided within a cloud environment and a physical plug-in configured to provide a virtual assembly builder-like environment on a physical platform. The physical assembly is an installable software suite including software configured to support provisioning of applications for providing services. The physical plug-in is configured to enable installation of the physical assembly on the physical platform. The physical plug-in is also configured to enable support for administering the services of the cloud platform component via the software installed from the physical assembly.
