摘要:
A method for coordinating phases of program execution within a data processing system. One or more program defined synchronization events are established. Each synchronization event is responded to by one or more programs to coordinate phases of execution. The operating system notifies the one or more programs when all responses are received. A next program defined synchronization event may be established after a response is received for a previous synchronization event.
摘要:
A method and system for rebuilding storage structures located within one or more structure processing facilities of a data processing system. A connection is made to a first storage structure having a name and one or more predefined characteristics. Thereafter, a second storage structure is allocated having the same name as the first structure, however, one or more of the predefined characteristics of the second structure are different than the predefined characteristics of the first structure. The second structure may be used for planned system reconfigurations or for recovery from system failures. During the rebuilding process, notification of phases of the rebuilding process are given to the active users. Further, a capability is provided for terminating the rebuilding process. In addition, a method and system for coordinating phases of user defined processing is provided.
摘要:
Provided are techniques for using a series of compare and swap operations to assign a Relative Byte Address (RBA) and a Logical Record Sequence Number (LRSN) to a log record. One or more log buffers for storing the log record are identified, and the log record is moved to the one or more log buffers.
