trackmod - Track modified pages enable configuration parameter

This parameter specifies whether the database manager will track database modifications so that the backup utility can detect which subsets of the database pages must be examined by an incremental backup and potentially included in the backup image.

Configuration type: Database
Parameter type: Configurable
Default [range]: No [Yes, No ]

After setting this parameter to "Yes", you must take a full database backup in order to have a baseline against which incremental backups can be taken. Also, if this parameter is enabled and if a table space is created, then a backup must be taken which contains that table space. This backup could be either a database backup or a table space backup. Following the backup, incremental backups will be permitted to contain this table space.
