Hi,
Hypermail reports wrong "Starting" and "Ending" dates for some folders.
To simulate, use the attached rc and mbox files ($ hypermail -c test.rc
-m test.mbx):
First folder:
1 messages: Starting Mon Mar 20 1995 - 09:08:17 CST,
Ending Mon Mar 20 1995 - 09:08:17 CST
Message listed:
Mon Jan 22 1996 - 03:01:34 CST

BTW: Hypermail version is pre-2.1.8 from the CVS Server.
Best regards.

dir = test

If all your disks are already mirrored (RAID1) then don't bother doing Oracle
mirroring on the REDO logs. Its extra overhead you don't need.
If you have only striped (RAID0) then you have no recoverability so
you should using the Oracle REDO log mirroring.
Having said that, it is not good practice to use RAID1 mirroring on
'write only' files because of the overhead and slowness of writes.
Better to RAID1 your database and keep things like REDO logs, RBS
and TEMP on other fast write devices. In this case you would use
Oracle's REDO log mirroring.

Dave Henley -
The problem is that USER_SOURCE is not really a table, it is a view. The
underlying table for that view is a data dictionary table owned by SYS.
Exporting a user doesn't really export any rows in the data dictionary
tables, it exports CREATE object commands for the objects owned by the user
