here's a function you can adapt, you'll need to set the parameters as per your site, but the logic works just fine...

chk_alert()
{
# Description: This function looks into alert file of oracle & reports
# all matches to ORA- pattern thru e-mail.
# It also pages DBA.

#Input: $LINE_FILE that stores line_no from where to start search
#Output: A mail containing all ORA- messages. Resets the $PARFILE with the
# current no. of lines.

if [ -f $LINE_FILE ] ; then
from_line=`cat $LINE_FILE`
if [ "$from_line" = "" ] ; then
from_line=1
fi
else
from_line=1
fi

if [ ! -f $ORA_EXCEPTIONS_FILE ] ; then
touch $ORA_EXCEPTIONS_FILE
fi

rm -f $LOG_LOC/diffs_${ORACLE_SID}
cur_lines=`wc -l $ALERT_FILE|cut -f1 -d' '`
# If the $cur_lines is less than the last line the script looked at last,
# it probably means that the alert.log file has been cycled. So assume
# that the file has not been read from and set $from_line = 1
if [ $cur_lines -lt $from_line ] ; then
from_line=1
fi
if [ $from_line -ne $cur_lines ] ; then
rm -f $LOG_LOC/chk_alert_${ORACLE_SID}.log
tail -n +$from_line $ALERT_FILE| grep "ORA-" > $LOG_LOC/chk_alert_${ORACLE_SID}.log

hi,

please see my post at this address:

Running it as the Oracle User, reschedules daily execution of script - morning, evening and night everyday (uses at)

hope this helps!
