Abstract: In accordance with an embodiment, a system and method provides a messaging service implementing a unit-of-order guarantee in a multitenant application server environment. The system and method of implementing unit-of-order utilizes an improved path service for routing all messages having a particular unit-of-order to the same member of the cluster. The improved path service allows for scalability of the cluster and reduced resource utilization, thereby improving the performance of a clustered computing system providing the messaging service.

Abstract: In accordance with an embodiment, a system and method provides a messaging service in a multitenant application server environment. Deployable resources are usable within the multitenant application server environment and groupings of resources are defined by resource group templates within a domain. One or more partitions are provided, with each partition providing an administrative and runtime subdivision of the domain that can be associated with a tenant. Java message service (JMS) resources are defined within a resource group template or a resource group, and instantiated within a partition from the one or more partitions to enable messaging for applications deployed within the partition and between the one or more partition.

Abstract: A system and method can provide a scalable data storage in a middleware environment. The system can include a cluster of replicated store daemon processes in a plurality of processing nodes, wherein each machine node can host a replicated store daemon process of the cluster of replicated store daemon processes. Additionally, the system can include one or more replicated stores associated with an application server the processing node. The replicated store daemon cluster can persist data from a replicated store to another node, the other node also being associated with the replicated store daemon cluster. The system and method can additionally support a messaging service in a middleware environment. The messaging service can use the replicated store to store a copy of a message in the local processing node and on another processing node associated with the same replicated store daemon cluster.
