Systems, methods, and non-transitory computer-readable media are disclosed for generating provisioning templates for application servers. An example method includes loading a first application server in a runtime environment, identifying features and associated files used by the first application server at runtime, generating a provisioning template including a description of the subset of the identified features and how the files support each of the subset of features, and using the provisioning template to configure a second application server.

Generating application-server provisioning configurations

A transaction sticky load balance policy allows a remote client to choose a target server node from a server cluster to provide a transaction service. The load balance policy directs invocations of business methods within a transaction to the same target server node. The remote client receives the load balance policy from a proxy, which is downloaded to the remote client from one of the server nodes in the server cluster. The remote client selects a target server node according to the load balance policy. The remote client then invokes the business methods within a transaction on the target server node via the proxy. The target server node can execute all of the business methods within the transaction on a Java virtual machine. The business methods can be implemented with Enterprise JavaBeans (EJBs).

A method and apparatus for replicating instances of cache nodes in a cluster is described. In one embodiment, the number of available cache nodes in the cluster is determined. Available cache nodes from the cluster are selected based on a parameter. An instance of a cache node is replicated to only one of the selected cache nodes in the cluster.

Replicating cache nodes in a cluster

A method and apparatus for obtaining data of a cache node in a tree-structured cluster is described. In one embodiment, a query for data in the cache node of the tree-structured cluster is received. A determination of whether the data is stored in the queried cache node is made. An inquiry of other cache nodes in the cluster for the data is performed. An instance of the data from a cache node storing the data is replicated to the cache node receiving the query.
