In a system where client and server components (or actors) of an application are organized as complementary hierarchical graphs, a method and apparatus for creating server applications and dynamically deploying server applications on a client system are described. The server graph comprises, as a minimum, server nodes corresponding to the union of all possible client nodes, whereas each client graph corresponds to a subset of the related server nodes. The server graph is a compound tree from which all possible combinations of client trees can be dynamically created. At a desired time, for example, when the client requests for a client tree representation, the server creates the client tree representation using a peeling process to determine which nodes in the server actor tree should be included in the client tree representation. The peeling process involves determining the server actor nodes that meet a set of criteria for the particular client. The generated client tree structure contains objects that are shipped via a secured communication interface to the client in a tree structure.

A system and method according to the present invention allow two or more peer-to-peer wireless devices to automatically connect to each other with no knowledge or pre-configuration of client/server roles. According to a first aspect of the present invention, a wireless device performs inquiries at a random interval, and performs an inquiry scan and a page scan when not performing the inquiries. Upon receiving a first device address in response to one of the inquiries, the wireless device performs a first page using the device address to establish a connection. And upon receiving an inquiry during the inquiry scan, the wireless device responds with a second device address, and if a second page is received during the page scan, establishes a connection.

A data storage system configured as node in a distributed data store is presented. The system comprises an RDMA-enabled network adapter and a role management unit. The RDMA-enabled network adapter is configured to communicate with one or more other data storage systems in the distributed data store. The role management unit is configured to: detect a node identification number associated with each of the other data storage systems, compare a node identification number assigned to the data storage system with each of the detected node identification numbers to generate comparison results, determine whether the data storage system is to perform either a server role or a client role with respect to each of the other data storage systems on the basis of the comparison results, and set up the network adapter to operate in both an RDMA server mode and an RDMA client mode during runtime according to the determined roles.

The invention provides a high-availability method for WINDOWS rendering cluster job scheduling. A failover cluster in a WINDOWS server is used for detecting and transferring single-point faults in job scheduling, in other words, high availability is achieved, the machine types of two job scheduling servers are mutually redundant, and therefore the HA function of a job scheduling system can be achieved; after a main server is shut down, a slave server detects that the main server is abnormal, a job scheduling slave server is automatically started, and switching is completed on a job scheduling client server. Compared with the prior art, the high-availability method for WINDOWS rendering cluster job scheduling can divide a cluster management node into two nodes, and therefore after crash of a job scheduling node happens, the task of job scheduling can be delivered to another machine so that another machine can take over the task, and resources can be high utilized, and continuous running of operation can be achieved.

The invention relates to a method and a system for determining roles of servers of a transformer substation monitoring system, which are used for solving the role determination problem of double setsof servers of transformer substation monitoring. Key node information interaction is carried out between two servers of a transformer substation monitoring system, the state and the interaction process of a server host are defined, the two parties negotiate to determine main and standby operation roles, and main and standby role determination and real-time dynamic switching are carried out. When the running state of the main server is abnormal in the running process, main and standby switching is carried out, the abnormal server is switched to the standby server, the normal server is switchedto the main server, and monitoring and operation services continue to be provided for an operator station. Through the determination method, the problem of determining the roles of main and standby servers of the transformer substation monitoring system in the dual-computer hot standby operation mode can be effectively solved, and the operation reliability of the transformer substation monitoringsystem is improved.

Provided are approaches for remote managing comprising at least one or more agents being resident in at least one or more management terminals connected to each other through a network and controlling the corresponding management terminals; and a management server transmitting to the agents a request for a service for managing the management terminals, where the management server transmits the request to the agent through a control channel. An independent control channel is formed between a management server and a management device separately from an ordinary communication channel and, in case the management device is required to perform a server role for a particular service, makes the corresponding management device require a request related to the service through a control channel and thus, the server role is assigned to the management server at the time of carrying out a service.
