Oracle数据库监控：报警日志文件及监听

1、下载SendEmail；

2、建立监控脚本：

[oracle@db1 scripts]$ cat check_lsnr_alterlog.sh
#!/bin/sh

#Oracle报警日志文件位置，10g与11g位置不同
v_alertlogpath="${ORACLE_BASE}/diag/rdbms/${v_dbname}/${v_oraclesid}/trace"
#####Oracle 报警日志文件监控代码开始#####
if [ -f ${v_alertlogpath}/alert_${v_oraclesid}.log ] ; then
cat ${v_alertlogpath}/alert_${v_oraclesid}.log > ${v_path}/alert_work_${v_oraclesid}.log
> ${v_alertlogpath}/alert_${v_oraclesid}.log
cat ${v_path}/alert_work_${v_oraclesid}.log >> ${v_alertlogpath}/alert_${v_oraclesid}.history

fi
if [ `cat ${v_path}/alert_${v_oraclesid}.err|wc -l` -gt 0 ] ; then

rm -f ${v_path}/alert_${v_oraclesid}.err
rm -f ${v_path}/alert_work_${v_oraclesid}.log
#####Oracle 报警日志文件监控代码结束#####
#####Oracle LISTENER 监控代码开始#####
rm -f ${v_path}/lsnr_${v_oraclesid}.exist
ps -ef|grep -i LISTENER|grep -v grep > ${v_path}/lsnr_${v_oraclesid}.exist
if [ -s ${v_path}/lsnr_${v_oraclesid}.exist ] ;then
echo
else

fi
#####Oracle LISTENER 监控代码结束#####

3、配置crontab，每一分钟执行一次

[oracle@db1 scripts]$ crontab -l
#oracle listener and alterlog check
*/1 * * * * /home/oracle/scripts/check_lsnr_alterlog.sh >/dev/null 2>&1
