IBM Domino 9 Social Edition introduces the new Database Management Tool (DBMT) to optimize and coordinate maintenance tasks on user mail databases such as compacting non-system databases, updating views and full-text indexes, and fixing databases. The DBMT allows scheduling maintenance tasks to run multiple times daily or weekly using command line options or program documents. It replaces the "Update All" mechanism and supports parameters to control the number of parallel threads, time ranges, and limits for each task.
