摘要： A method, apparatus and program product retrieve, in the client, class metadata of an object that is used by the computer program from a remote service, including retrieving object type data of the object, and dynamically generate on the client a proxy object for the object on the server. The object is dynamically created and resides on a server, and the type of the object is unknown to the computer program prior to retrieval of the class metadata. Furthermore, casting a type of the proxy object to a type that is specific to an interface known to the computer program without receiving any class cast exception. By doing so, the dynamically created proxy object may be utilized for remote method invocation in a distributed environment utilizing objects dynamically created on the server, often avoiding a costly deployment process and independent of any protocols.

摘要： A computer system and storage medium that, in an embodiment, receive an allocation request for a resource and registers the resource as a non-voting participant if the resource desires to delegate commit voting to another resource. The registered resource is then prohibited from participating in an enclosing transactional context and instead is informed when the transaction completes. The resource is enlisted as a voting participant if the resource does not desire to delegate commit voting. In this way, when multiple resources are used in a transaction, a resource may be registered and receive notifications of transaction completion instead of being enlisted and voting on commit decisions. The result of a transaction in which a single resource takes responsibility for a number of other resources is that transaction completion avoids the two-phase commit protocol and the resulting performance degradation.

摘要： An apparatus, program product and method monitor the state of a cache during a cache preload operation in a clustered computer system such that the monitored state can be used after a failover to potentially avoid the need to restart the cache preload operation from the beginning. In particular, by monitoring the state of the cache during a cache preload operation, any data that has been preloaded into a cache prior to a failure may be retained after a failover occurs, thus enabling the cache preload operation to continue from the point at which it was interrupted as a result of the failure.

摘要： In an embodiment, a request is received that includes data and a specification of a store operation, a key, and a local database. A predicted format for the data is determined based on a type of the requester and whether the local database is a primary database or a replica database. If the predicted format is a relational format, the data is converted to the relational format, if not already in the relational format, and stored into the local database. If a most-frequently predicted historical format is the relational format, the data is converted to the relational format, if not already in the relational format, and stored into the local database. If both the predicted format and the most-frequently predicted historical format are an object format, the data is converted into the object format, if not already in the object format, and stored into the local database.
