分类: Oracle

1.原平臺:windows 2003(32-bit)+Oracle 10.2.0.4

2.新平臺:Linux 5(64-bit)+Oracle 10.2.0.4

注:機器硬件不變(主備庫均4G內存),另外有兩臺臨時使用機器做切換使用

 

1.用臨時機器1建立windowsstandby

PS:和原庫建立一樣的OSOracle,以便撤下原備庫后,當standby臨時使用

1>先安裝10201_database_win32

只安裝軟件,不建DB

2>升級至10.2.0.4

安裝patch: p6810189_10204_Win32(運行setup.exe均為圖形操作)

3>創建和主庫的文件路徑:

select * from v$parameter where value like '%\%';

select * from dba_data_files;

select * from dba_temp_files;

4>copy密碼文件和參數文件

注意:windowsORACLE_HOME/database

5>開啟臨時standbynomount;

C:\Documents and Settings\Administrator>set oracle_sid=nbe2

C:\Documents and Settings\Administrator>sqlplus "/as sysdba"

SQL*Plus: Release 10.2.0.4.0 - Production on 星期二 11 15 10:30:26 2011

Copyright (c) 1982, 2007, Oracle.  All Rights Reserved.

ERROR:ORA-12560: TNS:協定介面程式錯誤

發現無法nomount,運行services.msc發現和原庫相比缺少OracleServicenbe2服務,重啟server后仍然不行,后使用oradim

C:\Documents and Settings\Administrator>oradim -new -sid nbe2

C:\Documents and Settings\Administrator>sqlplus "/as sysdba"

SQL> startup nomount;

ORACLE 執行處理已啟動.

Total System Global Area 1577058304 bytes

Fixed Size                  1299216 bytes

Variable Size             360713456 bytes

Database Buffers         1207959552 bytes

Redo Buffers                7086080 bytes

6>對主庫全備份,至臨時standby recover

主庫:

RMAN>backup database format='E:\rmanbak%U_%T.bak';

sql>alter database create standby controlfile as 'E:\control01.ctl';

備庫:

sql>startup nomunt;

sql>alter database mount standby database;

RMAN>restore database;

sql>alter system set standby_file_management=auto;

設置歸檔recover批處理

autoreco.bat:

if exist Y: then net use Y:  /delete  /y

net use Y:  \\10.107.5.15\e$ "gcmv&246" /user:administrator

 

Y:

cd oradata

cd nbe2

cd arch

 

xcopy /D *.arc e:\oradata\nbe2\arch >>d:\auto\autocopy_nbe2.log

 

e:

net use Y: /delete /y

 

set ORACLE_SID=nbe2

sqlplus /nolog @d:\auto\autoreco.bak >d:\auto\autoreco_nbe2.log

 

autoreco.bak:

connect / as sysdba

set autorecovery on

recover standby database;

exit;

 

2.用臨時機器2建立linuxstandby(先裝數據庫軟件)

3.用原standby機器建立linux的主庫(先裝數據庫軟件)

[root@linuxstandby ~]# vi /etc/sysctl.conf

kernel.shmall = 2097152  #must

kernel.shmmax = 2684354560 #2.5G sga+pgs=2G

kernel.shmmni = 4096

kernel.sem = 250 32000 100 128

fs.file-max = 65536

net.ipv4.ip_local_port_range = 1024 65000

net.core.rmem_default = 262144

net.core.rmem_max = 262144

net.core.wmem_default = 262144

net.core.wmem_max = 262144

[root@linuxstandby ~]# sysctl -p

 

 

其它配置和standby一樣。配置listener時注意如果配置非1521端口的話要加上:

nbe2<*nbe2*/data/nbe2>$vi /u01/product/oracle/network/admin/listener.ora

SID_LIST_LISTENER =

  (SID_LIST =

    (SID_DESC =

      (SID_NAME = PLSExtProc)

      (ORACLE_HOME = /u01/product/oracle)

      (PROGRAM = extproc)

    )

    (SID_DESC =

      (GLOBAL_DBNAME = nbe2)---service_name

      (ORACLE_HOME = /u01/product/oracle)

      (SID_NAME = nbe2)-----SID

    )

  )

 

安裝數據庫軟件后,DBCA創建數據庫

 

原來32DBSGA1304MPGA800M(實際使用350M左右)

DBSGA1600MPGA800M(DB64位系統4G內存,保守起見SGA比原來設大一點)

另注意1526端監聽的配置

 

LISTENER =

  (DESCRIPTION_LIST =

    (DESCRIPTION =

       #(ADDRESS = (PROTOCOL = TCP)(HOST = 10.107.5.15)(PORT = 1521))

        (ADDRESS = (PROTOCOL = TCP)(HOST = 10.107.5.15)(PORT = 1526))

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

    )

  )

 

4.為新庫建立臨時standby,準備使用LGWR方式傳輸

將主庫5.15設置為強制歸檔,防止一些操作如:insert /*+append*/  create table test as

不產生redo而導致standby不同步

select force_logging from v$database;

alter database force logging;

 

 

設置主庫參數

--alter system set log_archive_dest_state_2=defer

alter system set log_archive_dest_2='SERVICE=nbe2dg OPTIONAL LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=nbe2dg'

alter system set log_archive_config='dg_config=(nbe2,nbe2dg)'

--alter system set db_unique_name='nbe2'

alter system set fal_client='nbe2'

alter system set fal_server='nbe2dg'

 

 

 

設置主庫tnsnames.ora加入以下:

nbe2=

  (DESCRIPTION=

    (ADDRESS=

      (PROTOCOL=TCP)

      (HOST=10.107.5.15)

      (PORT=1526)

    )

    (CONNECT_DATA=

      (SERVICE_NAME=nbe2)

    )

  )

 

nbe2dg=

  (DESCRIPTION=

    (ADDRESS=

      (PROTOCOL=TCP)

      (HOST=10.107.5.54)

      (PORT=1526)

    )

    (CONNECT_DATA=

      (SERVICE_NAME=nbe2dg)

    )

  )

 

 

創建pfile,到standby上使用

create pfile from spfile;

 

scp listener.ora(修改host),tnsnames.ora,pfile,密碼文件到standby

standby需要修改的地方:

*.fal_client='nbe2dg'

*.fal_server='nbe2'

*.standby_file_management='AUTO'

*.db_unique_name='nbe2dg'

*.log_archive_dest_1='LOCATION=/data/nbe2/arch'

*.log_archive_dest_2='SERVICE=nbe2 OPTIONAL LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=nbe2'

还有控制文件路径,及各dump文件路径需要修改.

 

注意:要在standby配置local_listener,其實是因為port不是默認的1521無法動態注冊

SQL> alter system set local_listener='LISTENER_NBE2'

$vi tnsnames.ora

LISTENER_NBE2 =

  (ADDRESS = (PROTOCOL = TCP)(HOST = 10.107.5.54)(PORT = 1526))

 

為創建standby對主庫5.15主備,并創建standby control file

rman>backup database format='/data/rman/%U_%T.bak';

sql>alter database create standby controlfile as '/data/rmanbak/control01.ctl';

 

standby執行:

sql>startup nomunt;

sql>alter database mount standby database;

 

sql>alter database add standby logfile

group 11 ('/data/nbe2/log/dgredo01.log') size 100M;

sql>alter database add standby logfile

group 12 ('/data/nbe2/log/dgredo02.log') size 100M;

sql>alter database add standby logfile

group 13 ('/data/nbe2/log/dgredo03.log') size 100M;

sql>alter database add standby logfile

group 14 ('/data/nbe2/log/dgredo04.log') size 100M;

sql>alter database add standby logfile

group 15 ('/data/nbe2/log/dgredo05.log') size 100M;

采用LGWr进程传输日志,必须建立备用日志,而且日志大小与主库一样,个数比主库多一个

 

RMAN> restore database;

SQL>alter database recover managed standby database disconnect from session;

 

新主庫(5.15)開啟:

sql>alter system set log_archive_dest_state_2=enable

sql>alter system switch logfile;

 

 

5.數據的導出導入

原庫5.50 windows系統中導出6schema

set NLS_LANG=AMERICAN_AMERICA.AL32UTF8

expdp  system/"""system$oracle""" dumpfile=EXPDP_nbe2.dmp logfile=EXPDP_nbe2.log DIRECTORY=DUMP2 SCHEMAS=IMOLD,IMOLD_DEV,IMOLD_PDM,IMOLD_TEMP,RMS,RMS_DEV exclude=statistics

 

并對存放dmp文件的文件夾開啟共享,在我的電腦-管理-共用資料夾-共用 中可以看見,

在新庫中[root@nbe2 home]# smbclient //10.107.5.50/EXP -Uadministrator

Password:

Domain=[IMOLD-DB01] S=[Windows Server 2003 R2 3790 Service Pack 2] Server=[Windows Server 2003 R2 5.2]

  EXPDP_NBE2_02.DMP                   A 420679680  Wed Dec  7 11:26:11 2011

 

                49175 blocks of size 4194304. 31181 blocks available

smb: \> get EXPDP_NBE2.DMP

getting file \EXPDP_NBE2.DMP of size 1647906816 as EXPDP_NBE2.DMP (35998.7 kb/s) (average 35998.7 kb/s)

 

也可以嘗試

挂载windows文件共享:

mount -t smbfs -o username=admin,password=888888 //192.168.1.2/c$ /mnt/samba

mount -t cifs -o username=xxx,password=xxx //IP/sharename /mnt/dirname

 

 

新主庫(5.15)導入數據

nbe2<*nbe2*/home/oracle>$export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

nbe2<*nbe2*/home/oracle>$impdp 'system/"sys$oracle"' dumpfile=EXPDP_NBE2.DMP logfile=impdp_nbe2.log DIRECTORY=DUMP2

注意PUBLIC同義詞的創建

select 'CREATE PUBLIC SYNONYM '||synonym_name||' FOR '||table_owner||'.'||table_name||';' from dba_synonyms

where table_owner in('IMOLD','IMOLD_DEV','IMOLD_PDM','IMOLD_TEMP','RMS','RMS_DEV') and OWNER='PUBLIC';

注意JOB的建立是否到指定schema

 

 

收集統計信息

exec DBMS_STATS.GATHER_DICTIONARY_STATS;

exec DBMS_STATS.GATHER_SCHEMA_STATS(ownname=>'RMS',estimate_percent=>100, method_opt=>'FOR ALL COLUMNS SIZE SKEWONLY',degree=>4,cascade=>TRUE); 

exec DBMS_STATS.GATHER_SCHEMA_STATS(ownname=>'IMOLD',estimate_percent=>100, method_opt=>'FOR ALL COLUMNS SIZE SKEWONLY',degree=>4,cascade=>TRUE); 

exec DBMS_STATS.GATHER_FIXED_OBJECTS_STATS;

 

6.收尾工作

建立軟連接

nbe2dg<*nbe2*/home/oracle>$ln -s /u01/product/admin/nbe2/bdump/ bdump

 

7.建立新的standby

主庫需要修改的參數:

log_archive_config='dg_config=(nbe2,nbe2dg,nbe2dgnew)'

log_archive_dest_3='SERVICE=nbe2dgnew OPTIONAL LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=nbe2dgnew'

log_archive_dest_state_3=ENABLE

fal_server='nbe2dg,nbe2dgnew'

修改tns文件:

nbe2dgnew=

  (DESCRIPTION=

    (ADDRESS=

      (PROTOCOL=TCP)

      (HOST=10.107.5.15)

      (PORT=1526)

    )

    (CONNECT_DATA=

      (SERVICE_NAME=nbe2dgnew)

    )

  )

 

新備庫建立和上文一樣
