thanks robert,
i do it.... here its the solution:
i made an script which contains:
ORACLE_SID=mySid
export ORACLE_SID
ORACLE_HOME=/oracle/product/8.1.7
export ORACLE_HOME
$ORACLE_HOME/bin/exp userid=bob/boby file=/home/user/bob/exporta.dmp tables=factventa,producto,cliente,acumventa
the script was save as name.bat
then i use cron as follows:
crontab -e
and in the file i wrote:
00 23 * * * /home/user/bob/name.bat
thats all !!!
