International Classification:

G06F 13/00

US Classification:

711156, 711162, 711165

Abstract:

An electronic and computerized system that coalesces write operations using a buffer cache which stores data waiting to be written back to a disk of the electronic and computerized system is described. Dirty data blocks with consecutive data block addresses in the buffer cache are coalesced and written to the disk together. The disk head movements for performing the disk IOs are significantly reduced, thereby allowing the electronic and computerized system to maintain a high IO throughput and high peak performance with fewer disks.

Abstract:

A computer system having a kernel for mapping virtual memory address space to physical memory address space. The computer system uses a method for performing an input/output operation. A physical memory buffer is registered with a subsystem, and the physical memory buffer is associated with a first virtual address, a size and a key. The physical memory buffer is dynamically associated with a second virtual address which is different from the first virtual address. As part of an application program an input/output operation is requested regarding the second virtual address. An application table is used to obtain the first virtual address, the key and the size. The first virtual address, the key and the size are supplied to the subsystem. The subsystem uses the first virtual address, the key and the size, to determine the physical memory buffer and performs an input/output operation using the physical memory buffer without intervention of the kernel.

International Classification:

G06F 15/16

US Classification:

709218

Abstract:

A computer-implemented method of implementing a network file system may include steps of providing a host, the host including an Operating System (OS) that includes a kernel and a first client implementing the Network File System (NFS) protocol in the kernel, and a database server process. A second NFS client may be provided in the database server process. A NFS server may be provided, coupled to the host. A device implementing the Network Attached Storage (NAS) protocol may also be provided, coupled to the NFS server. NFS requests to access data stored in the NAS server may then be generated and sent from the second NFS client in the database server process directly to the NFS server, bypassing the first NFS client in the OS kernel of the host. NFS File handles obtained by one database process may be shared with other database processes through a shared memory area.

International Classification:

G06F 15/16

US Classification:

709206

Abstract:

A middleware machine environment can provide message queues for multinode applications. The transactional middleware machine environment includes a message control data structure on a message receiver and a heap data structure in a shared memory that is associated with the message receiver. The message sender operates to write a message directly into the heap data structure, and to maintain metadata associated with the message in the message control data structure. Furthermore, the message control data structure can be a ring structure with a head pointer and a tail pointer. Additionally, the message receiver resides on a server that is connected with a plurality of clients, with each of said clients keeping a private copy of the message control data structure. Also, the message receiver can support concurrent access to the message control data structure associated with the message receiver.

International Classification:

G06F 15/167

US Classification:

709213

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.

G06F 3/06

Abstract:

In accordance with an embodiment, described herein is a system and method for enabling persistence of application data, using replication over a remote direct memory access (RDMA) network. In an enterprise application server or other environment having a plurality of processing nodes, a replicated store enables application data to be written using remote direct memory access to the random access memory (RAM) of a set of nodes, which avoids single points of failure. Replicated store daemons allocate and expose memory to client applications via network endpoints, at which data operations such as reads and writes can be performed, in a manner similar to a block storage device. Resilvering can be used to copy data from one node to another, if it is determined that the number of data replicas within a particular set of nodes is not sufficient to meet the persistence requirements of a particular client application.

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.
