System and method for supporting patching in a multitenant application server environment
First Claim
1. A system for supporting patching in a multitenant application server environment, comprising:
- at least one computer and an application server environment executing thereon;
a plurality of managed server instances that operate within the application server environment as part of a domain that supports at least one partition or a plurality of partitions,wherein each partition, of the at least one partition or the plurality of partitions, provides a subdivision of the domain that provides a runtime for use by that partition, andwherein the system enables each partition, of the at least one partition or the plurality of partitions, to be associated with a tenant of the multitenant application server environment for use by that tenant; and
wherein the system uses a patching process that is performed by the application server environment to update the plurality of managed server instances in a controlled manner that maintains operations of the domain without interruption, including;
creating a patched home directory, andperforming a rollout of the patched home directory to the plurality of managed server instances, including for each managed server instance of the plurality of managed server instances;
shutting down the managed server instance,updating the managed server instance to use an instance of the patched home directory, andrestarting the managed server instance to cause the managed server instance to be updated according to the instance of the patched home directory.

Abstract
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.

7. A method for supporting patching in a multitenant application server environment, comprising:
-
executing, on at least one computer, an application server environment, together with a plurality of managed server instances that operate within the application server environment as part of a domain that supports at least one partition or a plurality of partitions, wherein each partition, of the at least one partition or the plurality of partitions, provides a subdivision of the domain that provides a runtime for use by that partition, and wherein each partition, of the at least one partition or the plurality of partitions, is enabled to be associated with a tenant of the multitenant application server environment for use by that tenant; and performing, by the application server environment, a patching process to update the plurality of managed server instances in a controlled manner that maintains operations of the domain without interruption, including; creating a patched home directory, and performing a rollout of the patched home directory to the plurality of managed server instances, including for each managed server instance of the plurality of managed server instances; shutting down the managed server instance, updating the managed server instance to use an instance of the patched home directory, and restarting the managed server instance to cause the managed server instance to be updated according to the instance of the patched home directory. - View Dependent Claims (8, 9, 10, 11, 12)
