Methods, apparatuses, and systems for file migration in distributed systems. A data structure definition is added to a programming language source code and initialized. Initialization values include contents of a first data file that is external to the source code file. The source code file is compiled with one or more other source code files to create an executable program that includes the initialization values as part of the program's image. During execution, the executable program creates a different second data file external to the executable program by reading the initialization values from the initialized data structure and writing the values to the second data file. This second data file is accessible by a library linked to the executable program.

File migration in distributed systems

Among other disclosed subject matter, a computer-implemented method for forwarding data includes receiving a data unit that is on a route toward a destination. The data unit is associated with a first limit value regarding forwarding of the data unit. The method includes causing the data unit to be associated with a second limit value at least equal to the first limit value. The method includes forwarding the data unit to a next recipient in the route, the data unit associated with the second limit value.

Forwarding data unit associated with limit value

Methods and apparatus, including computer program products, implementing and using techniques for resolving a hang condition in a distributed environment including a client computer and server computer(s). A network thread is provided, which passes requests from the client computer to the one or more server computers and responses from the server computers to the client computer. Worker thread(s) are provided on the server computers. The worker threads receive requests from the network thread, execute the requests, and pass responses to the requests back to the network thread. A request is sent from the client computer to a server computer through the network thread. A timer associated with the request is started on the client computer. The timer specifies a pre-defined time period for receiving a response to the request. When no response has been received within the pre-defined time period, a reset request is sent to the server computer.

System-hang recovery mechanisms for distributed systems

One embodiment of the present invention provides a system that identifies network switches along a path. During operation, the system receives an address of a source node and an address of a destination node. The system maintains a set of topology information for a network. The system further simulates a data packet originated at the source node and destined for the destination node. During the simulation, the system determines whether a current-hop node performs layer-3, layer-2, or sub-layer-2 switching. The system sends a query to the current-hop node over a separate control channel to determine the status of the current-hop node and discover a next-hop node. The system then receives a reply. The system determines the next-hop node based on the reply and sets the next-hop node as the current-hop node.

Method and system for discovering network paths

A method and system for providing virtual access to product/service information distributed across heterogeneous catalog systems is disclosed. The method and system include subscribing a first catalog server to at least a portion of the information stored on one or more remote catalog systems, thereby creating a subscribing catalog server. Thereafter, a replication process is performed to synchronize information on the subscribing catalog server with the subscribed information on the remote catalog systems. A user may then use the subscribing catalog server to search and browse the synchronized information, thereby providing one site for viewing information from multiple catalog servers.
