Abstract

See full text

Log records are generated by a computer system and stored in a computer readable storage area for recording changes to database objects responsive to receiving transaction requests, wherein the locators for the log records are of a predetermined maximum size that provides a maximum trackable size limit of the storage area. A computer system estimates an amount of time for the storing of the generated log records to fill the storage area up to the maximum trackable size limit. A computer system sets a soft limit to the storage area that is smaller than the maximum trackable size limit, including setting the soft limit based on the estimated amount of time.
