本来已经部署了sqlldr脚本 每小时定时导入 脚本如下
--文本文件每小时产生一次，格式为yyyymmddhh，每次sqlldr前将其重命名为固定名字source_file.csv，加载结束后还原
[root justin]# more sqlldr.sh
#!/bin/bash

ORACLE_HOME=/data/oracle/product/10205/db1
export ORACLE_HOME

folder=/var/www/data/

#get the past time value
date1=`date --date='1 hour ago'  +%Y%m%d%H`
date2=`date --date='15 day ago'  +%Y%m%d%H`

#rename the file generated one hour ago to source_file.csv, which would be called by control.ctl
mv "$folder""$date1"  "$folder"source_file.csv

#call sqlldr, with control as control.ctl
$ORACLE_HOME/bin/./sqlldr userid=****/*** control="$folder"control.ctl direct=false readsize=900000000 bindsize=900000000 rows=2000   log="$folder""$date1"-51
#rename bad file if generated
if [ -f "$folder"source_file.bad ]; then
 mv "$folder"source_file.bad "$folder""$date1"-51.bad
fi

#roll back the rename operation
mv "$folder"source_file.csv "$folder""$date1"

#if the file generated by 15 days ago still exist, then drop them
if [ -f "$folder""$date2" ]; then
  rm "$folder""$date2"
fi
if [ -f "$folder""$date2"-51.log ]; then
  rm "$folder""$date2"-51.log
fi
if [ -f "$folder""$date2"-51.bad ]; then
  rm "$folder""$date2"-51.bad
fi

偏偏最近修改脚本，到时sqlldr失效，又没有留意观察，导致半个月的数据没有导入；于是写了以下脚本监控
--每个文件使用sqlldr加载后，都会产生一个log文件，通过查看log文件是否存在判断sqlldr是否运行过；然后再通过判断log文件中的记录数查看是否成功加载
#!/bin/bash

folder=/var/www/data/
cd $folder
cat /dev/null > monitor_sqlldr.log
echo `ifconfig eth0 | grep 'inet' | sed 's/^.*addr://g' | sed 's/Bcast.*$//g' ` >> monitor_sqlldr.log
#get the past time value
end=`date --date='2 hour ago' +%Y%m%d%H`
start=`date --date='25 hour ago'  +%Y%m%d%H`

for (( i=$start; i<=$end; i=i+1 ))
do
  if [ -f $i ]; then
    file=$i"-51.log"
    if [ -f $file ] && [ "`wc -l < $file`" -gt "73" ]; then
      echo "$i has been successfully load into oracle" >> monitor_sqlldr.log
      cat $file | grep "Rows not loaded due to data errors" >> monitor_sqlldr.log
      echo "" >> monitor_sqlldr.log
    else
      echo "$i not loaded into oracle" >> monitor_sqlldr.log
      echo "" >> monitor_sqlldr.log
    fi
  fi

done

添加至crontab，每日的1点运行，得到昨天的sqlldr工作情况，邮件内容如下
