| DBMAutoDelete | |||||
| This parameter instructs the Database Manager to automatically delete entries from the table every time a new entry is created (affects normal and soft deleted entries). There are 5 possible criteria:
"[ENTRIES]n" is a maximum amount of n entries in the table. "[AGE]n" is a maximum age of the entries of n days. "[DELETEDATE]+n" is the number of elapsed days since the delete date was reached. By default only soft-deleted entries are deleted. If you precede the number of days by a '+' also normal entries are deleted. "[SOFTDELETED]n" deletes soft deleted entries that have not been changed during the past n days (n=1 means: have not been changed today, but n=0 means all soft deleted entries). "[FREESPACE]n" is a minimum free disk space of n MByte on the corresponding media path. "[DATE]datetype" defines which date/time (creation or change) is used when [AGE] is specified, and when entries must be auto deleted, defines the order of deletion (oldest by creation or by change date/time first). The value is either "CREATE" or "CHANGE". If this specification is missing or datetype is not one of these values, then "CREATE" is assumed. The [DATE] specification is new with version 5.6.8123.0; older versions always assume [DATE]CREATE. Specify a string with 1-6 sections. Example: "[ENTRIES]50[AGE]100[FREESPACE]500[DELETEDATE]0". Hint: The Database Manager cannot delete personal entries, so they shouldn't be used in this context. The logged in user must have the rights "Delete" and "Erase". The deletion criteria are executed one after another in following order: 1) If criteria AGE is defined, all entries are deleted which are older. 2) If criteria DELETEDATE is defined, all entries are deleted which have DELETEDATE defined and fullfil the corresponding auto delete criteria. 3) If SOFTDELETED is specified, entries that match this criterion are deleted. 4) If criteria FREESPACE or ENTRIES is defined, entries are deleted step by step, starting with the oldest, until criteria are/is fulfilled. Note: Except criteria DELETEDATE and SOFTDELETED all other criteria do not consider softdeleted flag. SOFTDELETED can only be used in DBM versions 5.3.7896.0 and later. |
