摘要： Disclosed are a method of and system for providing time synchronization among first and second computer systems, where each of the computer systems includes hardware, operating system software and a layer of microcode operating between said hardware and said software. The method comprises the steps of using the microcode of the first computer system to provide a first timestamp, using the microcode of the second computer system to provide a second timestamp and a third timestamp, and using the microcode of the first computer system to provide a fourth timestamp. The method comprises the further steps of using the first, second, third and fourth timestamps to determine a timing difference between the first and second computer systems, and adjusting the timing among said first and second computer systems on the basis of said determined timing difference. Preferably, the first and second computer systems are connected together by a point-to-point link; and the first timestamp is sent from the first computer system to the second computer system, and the second and third timestamps are sent from the second computer system to the first computer system over that point-to-point link.

摘要： A method for providing a message-time-ordering facility is disclosed. The method comprises initiating the message-timer ordering facility for a message at a sender system. Initiating includes setting a delay variable to zero. The message is sent to a receiver system in response to initiating the message-time-ordering facility. Sending the message includes marking the message with a first departure time-stamp responsive to a sender system clock and transmitting the message to the receiver system. The message is received at the at the receiver system, receiving includes delaying the processing of the message until the time on a receiver system clock is greater than the first departure time-stamp and recording a time associated with the delaying the processing of the message in the delay variable. A response to the message is sent to the sender system in response to receiving the message. Sending the response includes marking the response with a second departure time-stamp responsive to the receiver system clock if the delay variable is equal to zero and transmitting the response to the sender system. The response is received at the sender system. Receiving the response includes delaying the processing of the response if the delay variable is equal to zero until the time on the sender system clock is greater than the second departure time-stamp and recording a time associated with the delaying the processing of the response in the delay variable.

摘要： In a networked data processing system, the updating of timing parameters is carried out via a process in which the detection of the loss of communications with the network is not immediately employed as an indication of parameter invalidity but rather the process employs a system specific delay which permits actions such as server or link recovery to occur without necessitating the declaration of timing parameter invalidity.

摘要： Recovery is provided in a timing network. A configuration is defined for that network, and in that configuration, an active primary server is identified that provides a clock source for the network. Additionally, an alternate server is identified that can perform the role of the active primary server, should the active primary server fail. In response to a failure of the primary server, the alternate server detects the failure and performs takeover of the primary server.

摘要： A system, method and computer program product for dynamically debugging a multi-node network comprising an infrastructure including a plurality of devices, each device adapted for communicating messages between nodes which may include information for synchronizing a timing clock provided in each node. The apparatus comprises a plurality of probe links interconnecting each node with a probe device that monitors data included in each message communicated by a node. Each probe device processes data from each message to determine existence of a trigger condition at a node and, in response to detecting a trigger condition, generates a specialized message for receipt by all nodes in the network. Each node responds to the specialized message by halting operation at the node and recording data useful for debugging purposes. In this manner, debug information is collected at each node at the time of a first error detection and collected dynamically at execution time without manual intervention.
