我正在尝试编写一个shell脚本来监视ORACLE中的ASM实例，并将相应的人员邮寄到邮件列表中。我写了下面的脚本。shell脚本检查oracle中的ASM磁盘组空间并发送邮件

#/bin/sh

#set -x

USER=xxx

PASS=yyy

CC_OFFSHORE="[email protected] , [email protected] , [email protected]"

CC_TEAM="$CC_OFFSHORE , [email protected]"

. /home/oracle/.TESTenv #(NOT MANDATORY. DEPENDS ON YOUR ENVIRONMENT)

sqlplus -s $USER/$PASS << EOF

spool /home/oracle/SABARISH/RETVAL.log

set linesize 140

SET PAGESIZE 0 FEEDBACK OFF VERIFY OFF HEADING OFF ECHO OFF

select group_number,

name diskgroup,

round(((total_mb-nvl(free_mb,0))/decode(total_mb,0,1,total_mb))*100) pct_used,

round((free_mb/total_mb)*100) pct_free

from v\$asm_diskgroup

where total_mb >0

order by pct_free

)

/

spool off;

EOF

while read -r values

do

USED_PCT=$(echo $values | awk '{print $6}')

DISKGROUP_NAME=$(echo $values | awk '{print $2}')

WARNING_LIMIT=60

CRITICAL_LIMIT=70

if [ ${USED_PCT} -ge ${WARNING_LIMIT} ] && [ ${USED_PCT} -lt ${CRITICAL_LIMIT} ]

then

echo "WARNING ALERT. $DISKGROUP_NAME disk has used $USED_PCT%" | mailx -s "(WARNING ALERT $USED_PCT% used)" $CXC_OFFSHORE

elif [ ${USED_PCT} -ge ${CRITICAL_LIMIT} ]

then

echo "CRITICAL ALERT.$DISKGROUP_NAME disk has used $USED_PCT%" | mailx -s "(CRITICAL ALERT $USED_PCT% used)" $CXC_TEAM

fi

done < /home/oracle/SABARISH/RETVAL.log

上述脚本工作完美。

我需要做的就是在脚本中添加更多的细节。在执行ASM实例查询之前，我们需要检查数据库是否已启动并正在运行。

并检查特定用户的密码是否已过期或活动。

然后运行ASM查询。如果上述两个约束均失败，则不应执行ASM实例查询。它应该退出。

我该如何实现它？
