分享整理的sql脚本

1. 表空间使用率

SQL> select  a.tablespace_name,
  2          round(a.total_size) "total_size M",  
  3          round(a.total_size)-round(b.free_size,3) "used M",
  4          round(b.free_size ,3)  "free_size M",
  5          round(b.free_size/total_size *100,2) ||'%' free_rate
  6        from  (select  tablespace_name,sum(bytes) /1024/1024 total_size
  7               from dba_data_files  group  by  tablespace_name) a,
  8              (select  tablespace_name,sum(bytes)/1024/1024 free_size
  9               from  dba_free_space group by  tablespace_name)  b
 10  where   a.tablespace_name=b.tablespace_name(+);

TABLESPACE_NAME                total_size M     used M free_size M FREE_RATE
------------------------------ ------------ ---------- ----------- -----------------------------------------

2. 检查监听程序的配置

#!/bin/bash

export TMP=/tmp
export TMPDIR=$TMP
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1;
export ORACLE_SID=prod
export ORACLE_TERM=xterm
export PATH=/usr/sbin:$PATH
export PATH=$ORACLE_HOME/bin:$PATH; export PATH
export LD_LIBRARY_PATH=$ORACLE_HOME/lib:/lib:/usr/lib
export CLASSPATH=$ORACLE_HOME/JRE:$ORACLE_HOME/jlib:$ORACLE_HOME/rdbms/jlib;

lsn=`netstat -an |grep :1521 |head -1 |awk '{print $4}'|cut -c9-12`

if [ "$lsn" = '1521' ] ;then
 echo  "Current  Listener  Port is :  $lsn"
 echo   'listener is up !'
else
 echo "This   `hostname`   listener  is   down !"
 echo "Starting listener ...."
 lsnrctl   start
fi
3. 检查失效对象

spool off
exit
EOF
if [ `cat invalid_object.alert | wc -l` -gt 0 ]
then
mailx -s "INVALID OBJECTS for prod" $DBALIST < invalid_object.alert

4. 检查实例是否启动

for i in $db
do
echo "$pslist" | grep "ora_pmon_$i" > /dev/null 2>&1
if (( $? )); then
echo "Oracle Instance - $i: Down"
else
echo "Oracle Instance - $i: Up"

done

5.检查死锁

spool off
exit
EOF

then

5.检查表空间使用率的 shell脚本

#!/bin/bash

spool off
exit;
EOF

6.取样分析对象
set heading off
set feedback off
set pagesize 200
set linesize 100
set echo off
set time off
set timing off
set term off
set trimspool on
spool analyze_table.sql
select 'ANALYZE TABLE ' || owner || '.' || segment_name || ' ESTIMATE STATISTICS SAMPLE 10 PERCENT;' from dba_segments  where segment_type = 'TABLE' and owner not in ('SYS', 'SYSTEM');
spool off
