幾個重要的指令碼來監控Oracle資料庫
一、文章介紹8個重要的指令碼來監控Oracle資料庫:
1.檢查例項的可用性
2.檢查監聽器的可用性
3.檢查alert日誌檔案中的錯誤資訊
4.在存放log檔案的地方滿以前清空舊的log檔案
5.分析table和index以獲得更好的效能
6.檢查表空間的使用情況
7.找出無效的物件
8.監控使用者和事務
二、DBA需要的Unix基本知識
基本的UNIX命令,以下是一些常用的Unix命令:
ps--顯示程式
grep--搜尋檔案中的某種文字模式
mailx--讀取或者傳送mail
cat--連線檔案或者顯示它們
cut--選擇顯示的列
awk--模式匹配語言
df--顯示剩餘的磁碟空間
以下是DBA如何使用這些命令的一些例子:
1. 顯示伺服器上的可用例項:
$ ps -ef| grep smon
oracle 22086 1 0 02:32:24 0:04 ora_smon_PPRD10
oracle 5215 28972 0 08:10:19 pts/4 0:00 grep smon
2. 顯示伺服器上的可用監聽器:
$ ps -ef | grep listener |grep -v grep
(grep命令應該加上-i引數,即grep -i listener,該引數的作用是忽略大小寫,因為有些時候listener是大寫的,這時就會看不到結果)
$ ps -ef|grep -i listener
oracle 9655 1 0 Mar 12 0:01 /data/app/oracle/9.2.0/bin/tnslsnr LISTENER -inherit
oracle 22610 1 0 02:45:02 0:02 /data/app/oracle/10.2.0/bin/tnslsnr LISTENER -inherit
oracle 5268 28972 0 08:13:02 pts/4 0:00 grep -i listener
3. 檢視Oracle存檔目錄的檔案系統使用情況
$ df -k | grep /data
/dev/md/dsk/d50 104977675 88610542 15317357 86% /data
4. 統計alter.log檔案中的行數:
$ cat alert_PPRD10.log | wc -l
13124
$ more alert_PPRD10.log | wc -l
13124
5. 列出alert.log檔案中的全部Oracle錯誤資訊:
$ grep ORA-* alert.log
ORA-00600: internal error code, arguments: [kcrrrfswda.1], [], [], [], [], []
ORA-00600: internal error code, arguments: [1881], [25860496], [25857716], []
6. CRONTAB基本
一個crontab檔案中包含有六個欄位:
分鐘 0-59
小時 0-23
月中的第幾天 1-31
月份 1 - 12
星期幾 0 - 6, with 0 = Sunday
7. Unix命令或者Shell指令碼
要編輯一個crontab檔案,輸入: Crontab -e
要檢視一個crontab檔案,輸入: Crontab -l
0 4 * * 5 /dba/admin/analyze_table.ksh
30 3 * * 3,6 /dba/admin/hotbackup.ksh /dev/null 2>&1
在上面的例子中,第一行顯示了一個分析表的指令碼在每個星期5的4:00am執行。第二行顯示了一個執行熱備份的指令碼在每個週三和週六的3:
00a.m.執行。
三、監控資料庫的常用Shell指令碼
以下提供的8個shell指令碼覆蓋了DBA每日監控工作的90%,你可能還需要修改UNIX的環境變數。
1. 檢查Oracle例項的可用性
oratab檔案中列出了伺服器上的所有資料庫
$ cat /var/opt/oracle/oratab
#
# This file is used by ORACLE utilities. It is created by root.sh
# and updated by the Database Configuration Assistant when creating
# a database.
# A colon, ':', is used as the field terminator. A new line terminates
# the entry. Lines beginning with a pound sign, '#', are comments.
#
# Entries are of the form:
# $ORACLE_SID:$ORACLE_HOME::
#
# The first and second fields are the system identifier and home
# directory of the database respectively. The third filed indicates
# to the dbstart utility that the database should , "Y", or should not,
# "N", be brought up at system boot time.
#
# Multiple entries with the same $ORACLE_SID are not allowed.
#
#
# *:/data/app/oracle/9.2.0:N
TRNG:/data/app/oracle/9.2.0:Y
*:/data/app/oracle/9.2.0:N
PPRD:/data/app/oracle/10.2.0:Y
PPRD10:/data/app/oracle/10.2.0:N
以下的指令碼檢查oratab檔案中列出的所有資料庫,並且找出該資料庫的狀態(啟動還是關閉)
###################################################################
## ckinstance.ksh ##
###################################################################
ORATAB=/var/opt/oracle/oratab
echo "`date` "
echo "Oracle Database(s) Status `hostname` :/n"
db=`egrep -i ":Y|:N" $ORATAB | cut -d":" -f1 | grep -v "^#" | grep -v "^*"`
pslist="`ps -ef | grep pmon`"
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"
fi
done
使用以下的命令來確認該指令碼是可以執行的:
$ chmod 744 ckinstance.ksh
$ ls -l ckinstance.ksh
-rwxr--r-- 1 oracle dba 657 Mar 5 22:59 ckinstance.ksh
以下是例項可用性的報表:
$ sh ckinstance.ksh
Wed May 13 12:51:20 PDT 2009
Oracle Database(s) Status gambels :
Oracle Instance - PPRD: Up
Oracle Instance - PPRD10: Up
Linux :
###################################################################

echo "Oracle Database(s) Status `hostname`"
db=`egrep -i ":Y|:N" $ORATAB | cut -d":" -f1 | grep -v "^#" | grep -v "^*"`
pslist="`ps -ef | grep pmon`"
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"
fi
Done
Shell 2:
###################################################################
## ckinstance.ksh ##
###################################################################
echo "`date` "
echo "Oracle Database(s) Status `hostname` "
namelst=`ps -ef|grep ora_pmon|grep -v grep|awk '{print $8}'|cut -c10-15`
for name in $namelst
do
if [ -z $name ];then
echo "Oracle Instance - $name: Down"
else
echo "Oracle Instance - $name: Up"
fi
done
2. 檢查Oracle Instance 的可用性
#####################################################################
## cklsnr.sh ##
#####################################################################
#!/bin/ksh
TNS_ADMIN=/var/opt/oracle; export TNS_ADMIN
ORACLE_SID= PPRD10; export ORACLE_SID
ORAENV_ASK=NO; export ORAENV_ASK
PATH=$PATH:/bin:/usr/local/bin; export PATH
. oraenv
DBALIST="tianlesoftware@vi,tianle";export DBALIST
cd /var/opt/oracle
rm -f lsnr.exist
ps -ef | grep PPRD10 | grep -v grep > lsnr.exist
if [ -s lsnr.exist ]
then
echo "listener is up !"
else
echo "Alert" | mailx -s "Listener 'PPRD10' on `hostname` is down" $DBALIST
lsnrctl start PPRD10
fi
Linux:
檢查Oracle監聽器的可用性
以下有一個類似的指令碼檢查Oracle監聽器。假如監聽器停了,該指令碼將會重新啟動監聽器:
#!/bin/bash
lsn=`netstat -an |grep :1521 |head -1 |awk '{print $4}'|cut -c9-12`
echo "Current Listener Port is : $lsn"
if [ $lsn = '1521' ] ;then
echo 'listener is up !'
else
echo "This `hostname` listener is down !"
lsnrctl start
fi
3. 檢查Alert日誌(ORA-XXXXX)
####################################################################
## ckalertlog.sh ##
####################################################################
#!/bin/ksh
EDITOR=vi; export EDITOR
ORACLE_SID=PPRD10; export ORACLE_SID
ORACLE_BASE=/data/app/oracle; export ORACLE_BASE
ORACLE_HOME=$ORACLE_BASE/10.2.0; export ORACLE_HOME
LD_LIBRARY_PATH=$ORACLE_HOME/lib; export LD_LIBRARY_PATH
TNS_ADMIN=/var/opt/oracle;export TNS_ADMIN
NLS_LANG=american; export NLS_LANG
NLS_DATE_FORMAT='Mon DD YYYY HH24:MI:SS'; export NLS_DATE_FORMAT
ORATAB=/var/opt/oracle/oratab;export ORATAB
PATH=$PATH:$ORACLE_HOME:$ORACLE_HOME/bin:/usr/ccs/bin:/bin:/usr/bin:/usr/sbin:/sbin:/usr/openwin/bin:/opt/bin:.; export PATH
DBALIST="tianlesoftware@vi,tianle";export DBALIST
cd $ORACLE_BASE/admin/PPRD10/bdump
if [ -f alert_PPRD10.log ]
then
mv alert_PPRD10.log alert_work.log
touch alert_PPRD10.log
cat alert_work.log 》 alert_PPRD10.hist
grep ORA- alert_work.log > alert.err
fi
if [ `cat alert.err | wc -l` -gt 0 ]
then
mailx -s " PPRD10 ORACLE ALERT ERRORS" $DBALIST < alert.err
fi
rm -f alert.err
rm -f alert_work.log
改進版:
-----------------------------------------------------
name=cuug
cd $ORACLE_BASE/admin/"$name"/bdump
if [ -f alert_"$name".log ]
then
mv alert_$name.log alert_work.log
touch alert_$name.log
cat alert_work.log 》 alert_$name.hist
grep ORA- alert_work.log > alert.err
fi
if [ `cat alert.err | wc -l` -gt 0 ]
then
echo "Database is error … `date`" 》err.txt
fi
rm -f alert.err
rm -f alert_work.log
-----------------------------------------------------------
4. 清除舊的歸檔檔案
以下的指令碼將會在log檔案達到90%容量的時候清空舊的歸檔檔案:
$ df -k | grep arch
Filesystem kbytes used avail capacity Mounted on
/dev/vx/dsk/proddg/archive 71123968 30210248 40594232 43% /u08/archive
#######################################################################
## clean_arch.ksh ##
#######################################################################
#!/bin/ksh
df -k | grep arch > dfk.result
archive_filesystem=`awk -F" " '{ print $6 }' dfk.result`
archive_capacity=`awk -F" " '{ print $5 }' dfk.result`
if [ $archive_capacity > 90% ]
then
echo "Filesystem ${archive_filesystem} is ${archive_capacity} filled"
# try one of the following option depend on your need
find $archive_filesystem -type f -mtime +2 -exec rm -r {} ;
fi
Linux :
#!/bin/bash
export EDITOR=vi
export ORACLE_SID=oradb
export ORACLE_BASE=/u01/app/oracle
export ORACLE_HOME=$ORACLE_BASE/product/10.2.0/db_1
export ORA_CRS_HOME=$ORACLE_BASE/product/10.2.0/crs_1
export LD_LIBRARY_PATH=$ORACLE_HOME/lib
export PATH=$ORACLE_HOME/bin:$ORA_CRS_HOME/bin:/bin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/X11R6/bin
#######################################################################
## clean_arch.ksh ##
#######################################################################
#!/bin/bash
# $ df -k | grep arch
#Filesystem kbytes used avail capacity Mounted on
#/dev/vx/dsk/proddg/archive 71123968 30210248 40594232 43% /u08/archive
df -k | grep arch > dfk.result ;/u08/archive 檔案系統用於存放歸日誌
archive_filesystem=`awk -F" " '{ print $6 }' dfk.result`
archive_capacity=`awk -F" " '{ print $5 }' dfk.result`
if [ $archive_capacity > 90% ]
then
echo "Filesystem ${archive_filesystem} is ${archive_capacity} filled"
# try one of the following option depend on your need
arch_dir=/disk1/arch/oradb
for name in `find $arch_dir -type f -mtime +2`
do
mv $name /home/oracle/backup ;將超過兩天以上的歸檔日誌遷移到備份點
done
5. 分析表和索引(以得到更好的效能)
以下我將展示假如傳送引數到一個指令碼中:
####################################################################
## analyze_table.sh ##
####################################################################
#!/bin/ksh
# input parameter: 1: passWord # 2: SID
if (($#<1)) then echo "Please enter 'oracle' user password as the first parameter !" exit 0
fi
if (($#<2)) then echo "Please enter instance name as the second parameter!" exit 0
fi
要傳入引數以執行該指令碼,輸入:
$ analyze_table.sh manager oradb1
指令碼的第一部分產生了一個analyze.sql檔案,裡面包含了分析表用的語句。指令碼的第二部分分析全部的表:
#################################################################
## analyze_table.sh ##
#################################################################
sqlplus -s '/ as sysdba' 《EOF
set heading off
set feed off
set pagesize 200
set linesize 100
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
exit
EOF
sqlplus -s '/ as sysdba' 《EOF
@./analyze_table.sql
exit
EOF
以下是analyze.sql的一個例子:
$ cat analyze.sql
ANALYZE TABLE HIRWIN.JANUSAGE_SUMMARY ESTIMATE STATISTICS SAMPLE 10 PERCENT;
ANALYZE TABLE HIRWIN.JANUSER_PROFILE ESTIMATE STATISTICS SAMPLE 10 PERCENT;
ANALYZE TABLE APPSSYS.HIST_SYSTEM_ACTIVITY ESTIMATE STATISTICS SAMPLE 10 PERCENT;
ANALYZE TABLE HTOMEH.QUEST_IM_VERSION ESTIMATE STATISTICS SAMPLE 10 PERCENT;
ANALYZE TABLE JSTENZEL.HIST_SYS_ACT_0615 ESTIMATE STATISTICS SAMPLE 10 PERCENT;
Linux :
#!/bin/bash
####################################################################

####################################################################
# input parameter: 1: passWord # 2: SID
if (($#<1)) ;if [ $# -lt 1 ]
then
echo "Please enter 'sys' user password as the first parameter !"
read pass ; sys 使用者口令
fi
if (($#<2))
then
echo "Please enter service name as the second parameter!"
read name ;輸入連線的tnsnames中的連線符
fi
sqlplus "sys/$pass@$name as sysdba" 《EOF
set heading off
set feedback off
set pagesize 200
set linesize 100
set echo off
set time off
set term off
set trims 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
exit
EOF
lines=`cat analyze_table.sql|wc -l`
taillines=`expr $lines - 1`
tail -$taillines analyze_table.sql >1.tmp
headlines=`expr $taillines - 1`
head -$headlines 1.tmp > analyze_tab.sql
rm 1.tmp
sqlplus '/ as sysdba' 《EOF
@./analyze_tab.sql
exit
EOF
改進版:
------------------------
#!/bin/bash
####################################################################
## analyze_table.sh ##
####################################################################
# input parameter: 1: passWord # 2: SID
if (($#<1))
then
echo "Please enter 'sys' user password as the first parameter !"
read pass
fi
if (($#<2))
then
echo "Please enter service name as the second parameter!"
read name
fi
sqlplus "sys/$pass@$name as sysdba" 《EOF
set heading off
set feedback off
set pagesize 200
set linesize 100
set echo off
set time off
set term off
set trims 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
exit
EOF
lines=`cat analyze_table.sql|wc -l`
taillines=`expr $lines - 1`
tail -$taillines analyze_table.sql >1.tmp
headlines=`expr $taillines - 1`
head -$headlines 1.tmp > analyze_tab.sql
rm 1.tmp
sqlplus '/ as sysdba' 《EOF
@./analyze_tab.sql
exit
EOF
----------------------------
6. 檢查表空間的使用
以下的指令碼檢測表空間的使用。假如表空間只剩下10%,它將會傳送一個警告email。
