Method for restarting a long-running, fault-tolerant operation in a transaction-oriented data base system without burdening the system log

摘要

A restartable load without logging method permits the restart of a LOAD operation from the last COMMIT point without requiring the writing of images of loaded records to the log. Instead, the method logs only a minimal amount of information, recording positions within the data sets to be loaded and within the tablespace being loaded.
