listener监听监控脚本
以下两个脚本都是可以的，但是前提是脚本保存的文本的名称不能含有lsnr，因为ps -ef|grep lsnr|grep -v grep匹配了脚本名字
#!/bin/ksh
ps -ef|grep lsnr|grep -v grep>/dev/null
if [ $? -eq 0 ]; then
exit
else
echo `date`>/tmp/dsklog.lsnrctl
echo " The listener is down on 10.98.20.122">>/tmp/dsklog.lsnrctl
lsnrctl start>>/tmp/dsklog.lsnrctl
cat /tmp/dsklog.lsnrctl | /usr/local/bin/mailx -s "listener on 10.98.20.122 is down" luk.luk@chinadba.cn
fi
#!/bin/ksh
lsnr_flag=`ps -ef|grep lsnr|grep -v grep`
if [ -z "$lsnr_flag" ]; then
echo `date`>/tmp/dsklog.lsnrctl
echo " The listener is down on 10.98.20.122">>/tmp/dsklog.lsnrctl
lsnrctl start>>/tmp/dsklog.lsnrctl
cat /tmp/dsklog.lsnrctl | /usr/local/bin/mailx -s "listener on 10.98.20.122 is down" luk.luk@chinadba.cn
fi
#!/bin/ksh
ps -ef|grep lsnr|grep -v grep>/dev/null
if [ $? -eq 0 ]; then
exit
else

lsnrctl start>>/tmp/dsklog.lsnrctl
