This is useful for setting up automatic off-line backup procedures (see
"Backup and Data Recovery" on page 645 of the book ASA User’s Guide).
The format for the time is in hh:mm (24 hour clock), and can be preceded by
an optional date. If a date is specified, the date and time must be enclosed in
double quotes and be in the format YYYY/MM/DD HH:MM.
–u command-line option
Open files using the operating system disk cache.
[ dbsrv7 | dbeng7 ] -u ...
Windows NT, Windows 95/98, Windows 2000, UNIX
Files are opened using the operating system disk cache in addition to the
database cache.
While the operating system disk cache may improve performance in some
cases, in general better performance is obtained without this switch, using the
database cache only.
If the server is running on a dedicated machine, you should not use the
-u
option, as the database cache itself is generally more efficient. You may want
to use the
-u option if the server is running on a machine with several other
applications (so that a large database cache may interfere with other
applications) and yet IO-intensive tasks are run intermittently on the server
(so that a large cache will improve performance).
–ud command-line option
Run as a daemon.
[ dbsrv7 | dbeng7 ] -ud ...
UNIX
Using this option lets you run the server so that it continues running after the
current operating system session ends.
