DATABASE BACKUP PERFORMANCE

Abstract:

The indication of a database backup process starting is received. A plurality of buffer manipulator threads are marked as active. A determination is made whether any of the plurality of buffer manipulator threads marked as active in the database backup process become idle. In response to determining that at least one buffer manipulator thread in the database backup process becomes idle, the at least one idle buffer manipulator thread is reassigned to a first largest tablespace in the database that has not completed the database backup process. The first largest tablespace has a largest storage capacity relative to other tablespaces in the database.
