System and method for supporting use of an in-memory data grid with a multitenant application server environment

Abstract

In accordance with an embodiment, the system supports use of an in-memory data grid or other distributed memory environment, for example Oracle Coherence. A partition provides a runtime and administrative subdivision or slice of an application server domain. An application can be deployed to a particular partition, or otherwise associated with a particular domain partition name. The domain partition name can be used by the data grid to enable a separation of data between different partitions or between tenants associated with those partitions. In some embodiments, one or more data grid services, for example caches and clustered services, can be shared across multiple partitions. Alternatively, the data grid can provide read-shared/write-specific access to data grid services, in which multiple partitions can share an initial set of data, but their subsequent modifications to that data are then isolated from each other.
