Abstract

In accordance with an embodiment, described herein is a system and method for supporting dynamic security configuration in a multitenant application server environment. Common configuration changes required for partition level security can be made without requiring a server restart, such as for example, adding a new security realm for a partition; deleting an existing realm; changing the configuration on an existing realm; adding or removing a security provider to a realm; or changing the configuration of a security provider. In accordance with an embodiment, also described herein is a system and method for supporting dynamic reconfiguration in a multitenant application server environment. Attributes of partition management components, for example managed beans (MBeans) and child MBeans contained within a partition, can be made dynamic and annotated accordingly, so that a restart of servers is not required for configuration changes to those attributes for a particular partition.

Claims

1. A system for supporting dynamic reconfiguration in a multitenant application server environment, comprising one or more computers, including an application server environment executing thereon, together with

one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain, that can be associated with a tenant;

and

wherein attributes of a partition configuration bean and child beans contained within a partition are dynamic, so that no restart of servers is required for configuration change for a partition for those attributes.

2. The system of claim 1, wherein partition configuration elements and attributes can be annotated as dynamic at a configuration bean level.

3. The system of claim 2, wherein once an attribute has been annotated as being dynamic at the configuration bean level, the system, during build time, scans those annotations and determines dynamic and non-dynamic attributes, for subsequent use in configuring those attributes.

4. The system of claim 3, wherein changes to non-dynamic attributes are performed using a partition restart.

5. A method for supporting dynamic reconfiguration in a multitenant application server environment, comprising:

providing, at one or more computers, including an application server environment executing thereon,

one or more partitions, wherein each partition provides an administrative and runtime subdivision of a domain that can be associated with a tenant; and

wherein attributes of a partition configuration bean and child beans contained within a partition are dynamic, so that no restart of servers is required for configuration change for a partition for those attributes.

6. The method of claim 5, wherein partition configuration elements and attributes can be annotated as dynamic at a configuration bean level.

7. The method of claim 6, wherein once an attribute has been annotated as being dynamic at the configuration bean level, the system, during build time, scans those annotations and determines dynamic and non-dynamic attributes, for subsequent use in configuring those attributes.

8. The method of claim 7, wherein changes to non-dynamic attributes are performed using a partition restart.

9. A non-transitory computer readable storage medium, including instructions stored thereon which when read and executed by one or more computers cause the one or more computers to perform the steps comprising:

providing an application server environment, together with

one or more partitions, wherein each partition provides an administrative and runtime subdivision of the domain that can be associated with a tenant; and

wherein attributes of a partition configuration bean and child beans contained within a partition are dynamic, so that no restart of servers is required for configuration change for a partition for those attributes.

10. The non-transitory computer readable storage medium of claim 9, wherein partition configuration elements and attributes can be annotated as dynamic at a configuration bean level.

11. The non-transitory computer readable storage medium of claim 10, wherein once an attribute has been annotated as being dynamic at the configuration bean level, the system, during build time, scans those annotations and determines dynamic and non-dynamic attributes, for subsequent use in configuring those attributes.

12. The non-transitory computer readable storage medium of claim 11, wherein changes to non-dynamic attributes are performed using a partition restart.
