Abstract

A system and method for cluster-wide replication of embedded component configuration. In accordance with an embodiment, the system comprises an application server acting as a host and including one or more embedded components. When the configuration of an embedded component is modified from its original configuration, a configuration replication logic and deployment interface determines one or more appropriate configuration commands which, if executed at a target application server instance, for example, at another application server instance within a cluster, would result in an equivalent change in the state of an embedded component at that instance. The configuration commands are packaged within a configuration archive as one or more command payloads, which are distributed to target instances, and invoked on an embedded component thereon, to synchronize the configuration of the embedded components at the target instances with that of the host.

Claims

1. A system for cluster-wide replication of embedded component configuration, comprising:

a computer including a processor;

a host application server that includes a configuration replication logic and deployment interface, and one or more embedded components, each embedded component having an original configuration associated therewith;

wherein the system receives input to modify the original configuration of a particular embedded component provided at the host application server, and cause a configuration state change for the particular embedded component at the host application server;

wherein, at the host application server, the configuration replication logic and deployment interface;

determines, in response to the changed configuration state of the particular embedded component, one or more configuration commands to be executed at a target application server having the particular embedded component, to provide an equivalent change in configuration of the particular embedded component at the target application server, and

packages, within a configuration archive, each of the one or more configuration commands as a command payload, associates the command payloads with an order in which the commands were executed at the host application server, and distributes the configuration archive including the command payloads to the target application server; and

wherein, at the target application server, a listener, upon receipt and deployment of the configuration archive;

extracts the command payloads, and

invokes the associated configuration commands on the particular embedded component at the target application server, in the order the commands were executed at the host server, to modify the configuration of the particular embedded component at the target application server.

2. The system of claim 1, wherein the configuration archive is a web archive (WAR) file.

3. The system of claim 1, wherein the configuration archive bundles framework libraries needed to invoke the one or more command payloads in a clustered instance upon deployment.

4. The system of claim 1, wherein the configuration archive is deployed to a cluster that includes the host application server using an application deployment synchronization functionality provided by the host application server.

5. The system of claim 1, wherein the listener unmarshals and extracts dependencies in the command payloads, and executes the commands in the clustered target application server instance'"'"'s embedded component.

6. The system of claim 1, wherein the system includes a cluster having a plurality of nodes, whereupon a particular node being made available within the cluster, the one or more command payloads are invoked at the particular node according to the order that reflects modifications to the original configuration at the host server.

7. The system of claim 1, wherein the one or more command payloads are generated in an alphabetically increasing order by appending a server time to the configuration archive name.

8. The system of claim 1, wherein the listener listens to context initialized events, to determine the deployment of the configuration archive at the target application server.

9. The system of claim 1, wherein the listener is a servlet context listener that receives the one or more command payloads, upon deployment of the configuration archive to the target application server.

10. A method for cluster-wide replication of embedded component configuration, comprising:

providing, at a computer including a processor, a host application server that includes a configuration replication logic and deployment interface, and one or more embedded components, each embedded component having an original configuration associated therewith;

receiving input to modify the original configuration of a particular embedded component provided at the host application server, and cause a configuration state change for the particular embedded component at the host application server;

at the host application server;

determining, in response to the changed configuration state of the particular embedded component, one or more configuration commands to be executed at a target application server having the particular embedded component, to provide an equivalent change in configuration of the particular embedded component at the target application server, and

packaging, within a configuration archive, each of the one or more configuration commands as a command payload, associating the command payloads with an order in which the commands were executed at the host application server, and distributing the configuration archive including the command payloads to the target application server; and

at the target application server, upon receipt and deployment of the configuration archive;

extracting, by a listener, the command payloads, and

invoking the associated configuration commands on the particular embedded component at the target application server, in the order the commands were executed at the host server, to modify the configuration of the particular embedded component at the target application server.

11. The method of claim 10, wherein the configuration archive is a web archive (WAR) file.

12. The method of claim 10, wherein the configuration archive bundles framework libraries needed to invoke the one or more command payloads in a clustered instance upon deployment.

13. The method of claim 10, wherein the configuration archive is deployed to a cluster that includes the host application server using an application deployment synchronization functionality provided by the host application server.

14. The method of claim 10, wherein the listener unmarshals and extracts dependencies in the command payloads, and executes the commands in the clustered target application server instance'"'"'s embedded component.

15. The method of claim 10, wherein the method is performed within a cluster having a plurality of nodes, whereupon a particular node being made available within the cluster, the one or more command payloads are invoked at the particular node according to the order that reflects modifications to the original configuration at the host server.

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

providing a host application server that includes a configuration replication logic and deployment interface, and one or more embedded components, each embedded component having an original configuration associated therewith;

receiving input to modify the original configuration of a particular embedded component provided at the host application server, and cause a configuration state change for the particular embedded component at the host application server;

at the host application server;

determining, in response to the changed configuration state of the particular embedded component, one or more configuration commands to be executed at a target application server having the particular embedded component, to provide an equivalent change in configuration of the particular embedded component at the target application server, and

packaging, within a configuration archive, each of the one or more configuration commands as a command payload, associating the command payloads with an order in which the commands were executed at the host application server, and distributing the configuration archive including the command payloads to the target application server; and

at the target application server, upon receipt and deployment of the configuration archive;

extracting, by a listener, the command payloads, and

invoking the associated configuration commands on the particular embedded component at the target application server, in the order the commands were executed at the host server, to modify the configuration of the particular embedded component at the target application server.
