Abstract: Provided are methods, data processing systems, recovery components and computer programs for recovering from storage failures affecting data repositories. At least a part of the recovery processing is performed while the data repositories are able to receive new data and to allow retrieval of such new data. Although new data items may be received into the repository and retrieved therefrom during recovery processing, updates to the data repository which were performed before the failure and which are then restored to the repository by the recovery processing are restored within a recovery unit of work and are inaccessible to processes other than the recovery process until successful completion of the recovery unit of work. The recovery processing ensures that the recovered repository is consistent with the state of the repository at the time of the failure, but is available for addition and retrieval of new data items before completion of the recovery processing.

Abstract: A computer system has a recovery log to log records relating to units of work being performed by the computer system. The system logs records relating to the units of work in the recovery log in a series of log files. Those units of work that span more than a predetermined number of log files in the recovery log are identified as old units of work. A log restart record is entered into a log restart file for each of the units of work identified as old, the log restart record comprising a key identifying the unit of work and recovery information sufficient to allow the unit of work to be completed. The computer system is restarted following an interruption by establishing from the recovery log records the state of all currently active units of work, performing recovery activity for each old active unit of work based on the log restart records, and performing recovery activity for each of the remaining active units of work based on the recovery log records.

Abstract: Provided are a computer program, method and system providing simplified administration of groups of computer programs. Command target qualifiers are defined which enable a command to be targeted at either an individual computer program or all members of a group of computer programs. Additionally, scope parameters are defined which enable a command to be targeted at specific computer system resources managed by the computer programs within the group. The computer system resources which are to be accessible to all members of a group have an associated scope parameter defining shared or group access and are held in shared storage, whereas computer system resources to be accessed by only one computer program in the group have a corresponding scope parameter and are held in the local storage of the individual computer program. The invention enables a reduction of the time taken to perform administration and control operations for the group and reduces the risk of inconsistent specification of commands that can arise when a system administrator is required to repeat entry of a command several times.
