A software configuration management system that uses a network computing environment to build large software systems in parallel. A configuration manager assigns the compilation of buildable components of a software system to different processors in the network. Buildable components are assigned in order, according to dependencies between components, independent components taking precedence. Processors are chosen according to the amount of idle time during a sampled time segment. A display provides processor compilation status messages for each compilation discrete from status messages of other compilations. A continuously updated overall status report of the system being built is simultaneously displayed with, but segregated from, the compilation status messages.

Device for managing software configurations in parallel in a network

A support system for Computer-Aided Software Engineer (CASE) applications provides configuration management and features such as transparent retrieval of named versions of program sequences on a line by line basis as well as task monitoring and reporting. A modification record is maintained for all changes to the modules in the system build library by version numbers. Any version of a module can be obtained on a line by line basis as well as several different versions simultaneously thus supporting multiple concurrent system work on different versions by multiple users. Module monitoring is provided whereby if a module is modified when it is being monitored, all persons who might be affected thereby are notified. Task monitoring also provides notification and monitoring of tasks being accomplished as well as 'blueprints' to follow in the future for the accomplishment of the same or similar tasks.

Computer device for aiding in the development of software system

A transactional data base processing apparatus which executes plural transactions causing a data base to be updated, incorporates an after-image recovery storage apparatus and method which enables continuous operation of the transaction system. The after-image recovery storage apparatus has a temporary storage file and a permanent storage file with circuitry for writing from the temporary storage file to the permanent storage file. Tha circuitry also writes after-image updating data records to the temporary storage file. The apparatus further includes elements for initiating transfer of the after-image data records from the temporary storage file to the permanent storage prior to a time when the temporary file is filled with the data records. The transfer is accomplished by operating the apparatus on a time shared basis so that other ongoing operations including transactional operations occur as the after-image data is being transferred to a permanent storage device.
