Abstract: In accordance with an embodiment, described herein is a system and method for providing distributed caching in a transactional processing environment. The caching system can include a plurality of layers that provide a caching feature for a plurality of data types, and can be configured for use with a plurality of caching providers. A common data structure can be provided to store serialized bytes of each data type, and architecture information of a source platform executing a cache-setting application, so that a cache-getting application can use the information to convert the serialized bytes to a local format. A proxy server can be provided to act as a client to a distributed in-memory grid, and advertise services to a caching client, where each advertised service can match a cache in the distributed in-memory data grid, such as Coherence. The caching system can be used to cache results from a service.

Abstract: In accordance with an embodiment, described herein is a system and method for conditional call path monitoring in a distributed transactional middleware environment. A cache can be provided in local memory, for use by an agent in the reporting and aggregation of call path metrics. When the agent collects such metrics, it does not report them immediately to a system and application monitor (SAM) manager (e.g., Tuxedo System and Application Monitor, TSAM), but instead stores them in the cache, indexed by correlation ID (identifier). When a predefined condition is met at a participating node, that node propagates a corresponding correlation ID to other participating nodes, via the SAM manager. The other participating nodes can then search for the correlation ID in the cache, and report to the SAM manager metrics of call paths which meet the condition.

Abstract: A system and method for booting application servers in parallel. In an exemplary method, each server and server group entry can be associated with a dependency attribute. The method can create a dependency map based upon the dependency attributes. Servers that do not have a dependency can be booted in parallel. The remaining servers and server groups can be booted based upon the dependency map.

Abstract: In accordance with an embodiment, described herein is a system and method for making requests to a specific server in a transactional processing environment with a multiple servers, single queue (MSSQ) configuration. Each server in a MSSQ set can be associated with a secondary request queue, and can include a main thread, a secondary thread, and an internal memory queue. Each server can use an application programming interface (API) to advertise one or more non-unanimous services on a secondary request queue associated with that server. The secondary thread of a particular server is configured to dequeue, from the secondary request queue associated with the particular server, a request message for a non-unanimous service, and stores the dequeued message in the internal memory queue. The main thread of the particular server checks the internal memory queue before checking the main request queue for messages to process.

Abstract: A middleware machine environment can manage message queues for multimode applications. The middleware machine environment includes a shared memory on a message receiver, wherein the shared memory maintains one or more message queues for the middleware machine environment. The middleware machine environment further includes a daemon process that is capable of creating at least one message queue in the shared memory, when a client requests that the at least one message queue be set up to support sending and receiving messages. Additionally, different processes on a client operate to use at least one proxy to communicate with the message server. Furthermore, the middleware machine environment can protect message queues for multimode applications using a security token created by the daemon process.

Abstract: A transactional middleware system can exchange messages between a local machine and a remote machine using Remote Direct Memory Access (RDMA) protocol to achieve short latency in a manner like a local message transfer. The transactional middleware machine environment can prevent single-point bottleneck and achieve short latency. The transactional middleware machine environment comprises a first message queue associated with a server in a first transactional machine, wherein the server operates to be accessed using a queue address in the first message queue. The transactional middleware machine environment further comprises a second message queue associated with a client in a second transactional machine. The client operates to send a service request message to the server directly using the first message queue, and the server operates to receive the service request message from the first message queue and send a service response message directly to the client using the second message queue.

Abstract: A transactional system can utilize the distributed storage and high availability (HA) capability provided by a clustered database to support easy and feasible disaster recovery. The transactional middleware machine environment comprises one or more transactional application servers associated with a transaction. The one or more transactional application servers operate to persist transactional log information associated with the transaction in a database that connects with said one or more transactional application servers at a local site. The database at the local site operates to replicate the persisted transactional log information to a remote database at a remote site. The remote database allows a different transactional application server at the remote site to recover the persisted transactional log information and complete the transaction, when a disaster disables the local site.
