Hi, thank you for script.
But you have the error, you declare EXPORT_PATH but then use EXPORT_BACKUP_DIR
Hi NiCLoAy,
Sorry I’ve forgotten to make a var with EXPORT_BACKUP_DIR. In fact,
EXPORT_BACKUP_DIR is the name of a directory in oracle created with these sql:
CREATE DIRECTORY EXPORT_BACKUP_DIR AS ‘/opt/oracle/export_backup’;
Thanks for the comment I will update that soon.
Very useful. I tried this and working properly.
Thanks a lot.
thank you, very nice script.
but i had to edit every line, because there some very strange chars in there.
this : »
should be: »
dont know, perhaps its an encoding problem.
woudl recommend you supply a download link.
greetings

Hi,

Regards,
Bruce
Script is nice… Wat if the backup is failed eventhough it will send the success message..Appricated if you add the conditions(Failed message and success message).
Best Regards,
Fareed.
Thank’s a lot.
Ops … Mercy
