CORBA 2.6.1 Programmer's Guide for C++

Indicate number of days old a context must be to be considered for deletion (default 30).
-d <date1> [<date2>]
Specify a date or date range in the format mm/dd/yyyy. When a date is specified, contexts created prior to that date are candidates for
deletion. When two dates are specified contexts created between the two dates are candidates for deletion.
-p
<dblocation>
Specify the naming database on which to operate (identifies an enscribe file in the Guardian file space:
$<Volume>.<subvolume>.<dbfile>).
At most, one of -i, -w, -r should be specified. If none are specified, "-i" is assumed. At most, one of -t and -d should be specified.
If neither is specified all orphaned contexts older than 30 days are candidates for deletion. When -r is specified, the -t and -d options
have no effect.
