幾個重要的指令碼來監控Oracle資料庫

li__hl8888發表於2016-11-23

  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tableindex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5400am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8shell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 Databases 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 Databases Status gambels :

  echo "Oracle Databases 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 Databases 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

  ####################################################################

  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

  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

  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

  then

  cat tablespace.alert > tablespace.tmp

  mailx -s "TABLESPACE  ALERT  for  PPRD10" $DBALIST < tablespace.tmp
