    Abstract: A technique for establishing a logical path between two servers in a coor dinated timing network of processing environment is provided. The technique includes the exchange of command and response message pairs by a server and an attached server, via a physical link. The server transmits a command mess age to an attached server to establish a server-time-protocol(STP) logical p ath and receives a response from the attached server. The technique also inc ludes the server receiving a request transmitted by the attached server to e stablish an STP logical path to the server and transmitting a response to th e attached server s request. A logical path between the server and the attac hed server is established if the attached server s response indicates that t he server s request was accepted bythe attached server and if the server s r esponse indicates that the attached server s request was accepted by the ser ver.

    Abstract: Se proporciona un producto de programa de computadora para realizar: envío, por un subsistema de canal, de un mensaje de solicitud de entrada en el sistema de proceso (PRLI) a la unidad de control que indica si el subsistema de canal soporta transferencia de datos bidireccional; recibir un mensaje de respuesta PRLI de la unidad de control que indica si la unidad de control soporta transferencia de datos bidireccional; recolectar una pluralidad de comandos, al menos unos de los cuales especifica una transferencia de datos de entrada y al menos uno que especifica una transferencia de datos de salida, enviar al menos un mensaje de datos de salida a la unidad de control que incluye datos de salida a transferir a la unidad de control, el mensaje de datos de salida asociado con al menos una de la pluralidad de comandos que especifica una transferencia de datos de salida; y recibir al menos un mensaje de entrada de la unidad de control que incluye datos de entrada para guardar en un almacenamiento principal del sistema de computadora anfitrión.

    Abstract: Server time protocol (STP) messages and methods of exchange thereof are provided for facilitating synchronization of processing units of a timing network. The STP messages include exchange time parameters (XTP) commands and responses, and STP control (STC) commands and responses. XTP message exchange processing includes: generating an XTP message command at a first processing unit including a command transmit timestamp field set bythe first processing unit and a command receive timestamp field which is unset by the first processing unit; transmitting the XTP message command to a second processing unit; setting the command receive timestamp field in the XTP command with the time the XTP command is received at the second processing unit; and generating an XTP message response at the second processing unit, the message response including the command transmit timestamp set by the first processing unit and the command receive timestamp set by the second processing unit.

    Abstract: A computer program product is provided for performing: sending, by a channel subsystem, a process login (PRLI) request message to the control unit that indicates whether the channel subsystem supports bi-directional data transfer; receiving a PRLI response message from the control unit that indicates whether the control unit supports bi-directional data transfer; gathering a plurality of commands, at least one which specifies an input data transfer and at least one specifying an output data transfer; sending at least one output data message to the control unit including output data to be transferred to the control unit, the output data message associated with the at least one of the plurality of commands specifying an output data transfer; and receiving at least one input message from the control unit including input data to be stored in a main storage of the host computer system.

    Abstract: A state of an input/output (I/O) operation in an I/O processing system is determined. A request for performing the I/O operation is received from an I/O operating system at a channel subsystem and forwarded to a control unit controlling an I/O device for executing the I/O operation. After a predetermined amount of time passes without receiving indication from the control unit that the I/O operation is completed, an interrogation request is received at the channel subsystem from the I/O operating system for determining the state of the I/O operation. An interrogation command is sent from the channel subsystem to the control unit. A response is received from the control unit, the response indicates a state of the I/O device executing the I/O operation, a state of the control unit controlling the I/O device executing the I/O operation, and the state of the I/O operation being executed.

    Abstract: Se determina un estado de una operación de entrada/salida (I/O) en un sistema de procesamiento I/O. Una solicitud para llevar a cabo la operación I/O se recibe de un sistema operativo I/O a un subsistema de canales y es reenviada a una unidad de control que controla un dispositivo I/O para ejecutar la operación I/O. Después de que una cantidad de tiempo predeterminada pasa sin recibir la indicación por parte de la unidad de control de que la operación I/O está completada, se recibe una petición de interrogación en el subsistema de canales del sistema operativo I/O para determinar el estado de la operación I/O. Una orden de interrogación es enviada del subsistema de canales a la unidad de control. Se recibe una respuesta de la unidad de control, la respuesta indica un estado del dispositivo I/O que ejecuta la operación I/O, un estado de la unidad de control que controla el dispositivo I/O que ejecuta la operación I/O, y el estado de la operación I/O que se está ejecutando.
