This parameter specifies the interval of time (in days) files would be retained on an archive server (such as an ADSM server) after a DROP DATABASE is issued.
The default value for this parameter is one (1) day. A value of zero (0) means that the files are deleted immediately from the archive server when the DROP command or statement is issued. (The actual file is not deleted unless the ON UNLINK DELETE parameter was specified for the DATALINK column.)
This parameter applies to the DATALINK columns that specify "Recovery=Yes".
