你们知道什么是standby安装么,这个非常高深的运用技术将由我来非常讲解，standby安装NB在哪呢，下面我来进入讲述standby安装的无限领域与Primary和standby安装oracle 10G。

standby安装步骤。

Primary设置

1)修改主库属性

我这里选用192.168.1.79作为primary。[oracle@centos79 ~]$ sqlplus /nolog SQL*Plus: Release 10.2.0.1.0 - Production on Fri Aug 14 13:45:14 2009 Copyright (c) 1982, 2005, Oracle. All rights reserved.SQL> conn / as sysdbaConnected.SQL> alter database force logging;alter database force logging ERROR at line 1:ORA-12920: database is already in force logging mode之前改过了。SQL>

2)修改数据库为归档模式

SQL> archive log list)Database log mode) Archive Mode Automatic archival))) EnabledArchive destination)))USE_DB_RECOVERY_FILE_DESTOldest online log sequence) 3 Next log sequence to archive 5 Current log sequence))5 SQL>现在数据库已经运行在归档模式下。

3)创建密码文件

同一个Dataguard中所有数据库必须拥有独立的密码文件，并且保证sys用户拥有相同密码来保证redo的传输。[oracle@centos79 dbs]$ orapwd file='/usr/local/ora10/product/10.2.0/db_1/dbs/orapworcl.ora' password=system entries=10

4)standby配置oracle 10G

Su到root用户在/home下创建存放standby redo log目录SQL> shutdown immediateSQL> startup mountAlter database add standby logfile group 4('/home/oracle/oracle/dgredo/standby_redo4a.log','/home/oracle/oracle/dgredo/standby_redo4b.log') size 50M;

5)创建primary数据库初始化参数

通过修改创建的pfile，然后重新生成spfile,SQL> create pfile from spfile;File created.SQL>备份一份pfile.cp /usr/local/ora10/product/10.2.0/db_1/dbs/initorcl.ora /home/oracle/oracle/

6)设置主库参数文件

*.db_name='orcl'

*.DB_UNIQUE_NAME='primary'

*.log_archive_config='DG_CONFIG=(primary,standby)'

*.log_archive_dest_1='location=/usr/local/ora10/flash_recovery_area/ VALID_FOR=(ALL_LOGFILES,ALL_ROLES)' DB_UNIQUE_NAME='primary'

*.log_archive_dest_2='SERVICE=orcl76 arch ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=standby'

*.LOG_ARCHIVE_DEST_STATE_1=ENABLE

*.LOG_ARCHIVE_DEST_STATE_2=ENABLE

*.remote_login_passwordfile='EXCLUSIVE'#standby角色参数

*.FAL_SERVER=orcl76

*.FAL_CLIENT=orcl79

DB_FILE_NAME_CONVERT=’oradata/orcl’,’oradata/orcl’

LOG_FILE_NAME_CONVERT=’oradata/orcl’,’oradata/orcl’

.standby_FILE_MANAGEMENT=AUTO

7)用pfile启动数据库

SQL> Shutdown immediate

SQL> startup pfile='/usr/local/ora10/product/10.2.0/db_1/dbs/initorcl.ora'

SQL> create spfile from pfile='/usr/local/ora10/product/10.2.0/db_1/dbs/initorcl.ora';

SQL> shutdown immediate

SQL> startup

8)修改listener.ora

[oracle@centos79 admin]$ cat listener.ora

# listener.ora Network Configuration File: /usr/local/ora10/product/10.2.0/db_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =

(SID_DESC =

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /usr/local/ora10/product/10.2.0/db_1)

(PROGRAM = extproc)

LISTENER =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

(ADDRESS = (PROTOCOL = TCP)(HOST = centos79)(PORT = 1522))

LISTENER1 =

(DESCRIPTION_LIST =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

(ADDRESS = (PROTOCOL = TCP)(HOST = centos79)(PORT = 1523))

9)修改tnsnames.ora文件

[oracle@centos79 admin]$ cat tnsnames.ora

# tnsnames.ora Network Configuration File: /usr/local/ora10/product/10.2.0/db_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

LISTENER_ORCL =

(ADDRESS = (PROTOCOL = TCP)(HOST = centos79)(PORT = 1522)

ORCL79 =

(DESCRIPTION =)

(ADDRESS = (PROTOCOL = TCP)(HOST = centos79)(PORT = 1522)

(ADDRESS = (PROTOCOL = TCP)(HOST = centos76)(PORT = 1522)

(CONNECT_DATA =)

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

ORCL76 =

(DESCRIPTION =)

(ADDRESS = (PROTOCOL = TCP)(HOST = centos76)(PORT = 1521)

(ADDRESS = (PROTOCOL = TCP)(HOST = centos79)(PORT = 1521)

(CONNECT_DATA =)

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

ORCL254 =

(DESCRIPTION =)

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.254)(PORT = 1521)

(CONNECT_DATA =)

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

EXTPROC_CONNECTION_DATA =

(DESCRIPTION =)

(ADDRESS_LIST =)

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)

(CONNECT_DATA =)

(SID = PLSExtProc)

(PRESENTATION = RO)

[oracle@centos79 admin]$

确保tnsping两台机器都能 ping通

10)备份数据库

RMAN> backup full database format '/home/oracle/oracle/backup_%T_%s_%p.bak';

11)创建standby数据控制文件

SQL> alter database create standby controlfile as '/home/oracle/oracle/dgredo/standby.ctl';

Database altered.

SQL>

12)拷贝密码文件，数据文件，standby controlfile到备机

[oracle@centos79 orcl]$ scp /home/oracle/oracle/dgredo/standby.ctl root@192.168.1.76:/usr/local/ora10/oradata/orcl/

standby安装配置

1)创建对应目录

$ORACLE_BASE下oradata,admin,flash_recovery_area目录

2)拷贝文件，包括数据文件，standby controlfile，全库备份文件，参数文件，监听和服务文件

[root@centos79 dbs]# scp initorcl.ora orapworcl.ora oracle@192.168.1.76:/usr/local/ora10/product/10.2.0/db_1/dbs/

root@centos79 admin]# scp listener.ora sqlnet.ora tnsnames.ora oracle@192.168.1.76:/usr/local/ora10/product/10.2.0/db_1/network/admin/

3)创建控制文件

[oracle@centos76 orcl]$ mv standby.ctl /usr/local/ora10/oradata/orcl/control01.ctl

[oracle@centos76 orcl]$ cp control01.ctl /usr/local/ora10/oradata/orcl/control02.ctl

[oracle@centos76 orcl]$ cp control01.ctl /usr/local/ora10/oradata/orcl/control03.ctl

[oracle@centos76 orcl]$

4)配置listener,tnsname

Lintener.ora文件如下。[oracle@centos76 admin]$ cat listener.ora

# listener.ora Network Configuration File: /usr/local/ora10/product/10.2.0/db_1/network/admin/listener.ora

# Generated by Oracle configuration tools.

SID_LIST_LISTENER =

(SID_LIST =)

(SID_DESC =)

(SID_NAME = PLSExtProc)

(ORACLE_HOME = /usr/local/ora10/product/10.2.0/db_1)

(PROGRAM = extproc)

LISTENER =

(DESCRIPTION_LIST =)

(DESCRIPTION =)

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1)

(ADDRESS = (PROTOCOL = TCP)(HOST = centos76)(PORT = 1521)

LISTENER1 =

(DESCRIPTION_LIST =)

(DESCRIPTION =)

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

(ADDRESS = (PROTOCOL = TCP)(HOST = centos76)(PORT = 1522)

TNSNAMES.ORA文件如下

[oracle@centos76 admin]$ cat tnsnames.ora

# tnsnames.ora Network Configuration File: /usr/local/ora10/product/10.2.0/db_1/network/admin/tnsnames.ora

# Generated by Oracle configuration tools.

LISTENER_ORCL =(ADDRESS = (PROTOCOL = TCP)(HOST = centos79)(PORT = 1522))

ORCL79 =(DESCRIPTION =)

(ADDRESS = (PROTOCOL = TCP)(HOST = centos79)(PORT = 1521))

(CONNECT_DATA =)

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

ORCL76 =

(DESCRIPTION =)

(ADDRESS = (PROTOCOL = TCP)(HOST = centos76)(PORT = 1521))

(CONNECT_DATA =)

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

ORCL254 =

(DESCRIPTION =)

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.254)(PORT = 1521))

(CONNECT_DATA =)

(SERVER = DEDICATED)

(SERVICE_NAME = orcl)

EXTPROC_CONNECTION_DATA =

(DESCRIPTION =)

(ADDRESS_LIST =)

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))

(CONNECT_DATA =)

(SID = PLSExtProc)

(PRESENTATION = RO)

5)设置备库参数文件

*.db_name='orcl'

*.DB_UNIQUE_NAME='standby'

*.log_archive_config='DG_CONFIG=(primary,standby)'

*.log_archive_dest_1='location=/usr/local/ora10/flash_recovery_area/ VALID_FOR=(ALL_LOGFILES,ALL_ROLES)' DB_UNIQUE_NAME='standby'

*.log_archive_dest_2='SERVICE=orcl79 arch ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=parimary'

*.LOG_ARCHIVE_DEST_STATE_1=ENABLE

*.LOG_ARCHIVE_DEST_STATE_2=ENABLE

*.remote_login_passwordfile='EXCLUSIVE'

#standby角色参数

*.FAL_SERVER=orcl79

*.FAL_CLIENT=orcl76

DB_FILE_NAME_CONVERT=’oradata/orcl’,’oradata/orcl’

LOG_FILE_NAME_CONVERT=’oradata/orcl’,’oradata/orcl’

*.standby_FILE_MANAGEMENT=AUTO

6)standby安装创建密码文件

[oracle@centos76 ~]$ orapwd file='/usr/local/ora10/product/10.2.0/db_1/dbs/orapworcl76.ora' password=system entries=20

7)在备库上建立spfile

$ sqlplus '/as sysdba'SQL> create spfile from pfile;

启动物理备库

SQL> startup nomount

SQL> alter database mount standby database;

备库做rman恢复

$ rman target /) (要求主备库rman备份文件的存放路径和文件名一致)

RMAN> restore database;

Starting restore at 18-AUG-09

Starting implicit crosscheck backup at 18-AUG-09

using target database control file instead of recovery catalog

allocated channel: ORA_DISK_1

channel ORA_DISK_1: sid=153 devtype=DISK

Crosschecked 8 objects

Finished implicit crosscheck backup at 18-AUG-09

Starting implicit crosscheck copy at 18-AUG-09

using channel ORA_DISK_1

Crosschecked 4 objects

Finished implicit crosscheck copy at 18-AUG-09

searching for all files in the recovery area

cataloging files...

no files cataloged

using channel ORA_DISK_1

channel ORA_DISK_1: starting datafile backupset restore

channel ORA_DISK_1: specifying datafile(s) to restore from backup set

restoring datafile 00001 to /usr/local/ora10/oradata/orcl/system01.dbf

restoring datafile 00002 to /usr/local/ora10/oradata/orcl/undotbs01.dbf

restoring datafile 00003 to /usr/local/ora10/oradata/orcl/sysaux01.dbf

restoring datafile 00004 to /usr/local/ora10/oradata/orcl/users01.dbf

channel ORA_DISK_1: reading from backup piece /home/oracle/oracle/backup_20090818_11_1.bak
