schedule export

What I would do is to write a small script that does the export.  Then schedule that through cron.

Here is the documentation for the cron file (aka crontab) -> http://www.manpagez.com/man/5/crontab/

If your version of crontab supports it, you should run the "crontab -e".  That should bring up the current version of the file and allow you to edit it.  Once you save it, it will be loaded for you.

Be sure that whatever script you write sets up the Oracle environment.  Command run through cron do not execute your login scripts, so absolutely no environment variables will be set up before the script is run.

Maybe some of these might help you in findung "your" way ;-)

Hi Tony, just as background, can you provide:

-- the database version;
-- whether or not you mean export, or its replacement, datapump (expdp);
--  whether or not the database instance is running in ARCHIEVELOG mode (changes captured as REDO, written, saved as archive logs)

Where I'm going with this, is to educate you on having a recoverable backup.  Export is good for having copies of stuff, but awkward to restore from.

fine thanks..
