2024-10-07 12:59:39 218人阅读

环境

名称	主库	备库
主机名	bjsrv	shsrv
软件版本号	RedHat Enterprise5.5、Oracle 11g 11.2.0.1	RedHat Enterprise5.5、Oracle 11g 11.2.0.1

三、环绕备库操作：

1、备库-改动初始化參数文件

$cd$ORACLE_HOME/dbs

$df -h

技术分享

$vi initshdb.ora

改动简要说明：

*.audit_file_dest=‘/u01/app/oracle/admin/sh/adump‘

//审计文件存放的路径

*.audit_trail=‘db‘

*.compatible=‘11.2.0.0.0‘

*.control_files=‘/u01/app/oracle/oradata/sh/sh_control01.ctl‘

*.db_block_size=8192

*.db_name=‘TestDB12‘

*.db_recovery_file_dest=‘/u01/app/oracle/fast_recovery_area‘

*.db_recovery_file_dest_size=4322230272

*.diagnostic_dest=‘/u01/app/oracle‘

*.dispatchers=‘(PROTOCOL=TCP) (SERVICE=TestDB12XDB)‘//用于共享，删除

*.log_archive_format=‘arch_%t_%s_%r.log‘

*.memory_target=642006528

*.open_cursors=300

*.processes=150

*.remote_login_passwordfile=‘EXCLUSIVE‘

*.undo_tablespace=‘UNDOTBS1‘

DB_UNIQUE_NAME=shdb

LOG_ARCHIVE_CONFIG=‘DG_CONFIG=(bjdb,shdb)‘

LOG_ARCHIVE_DEST_1=

‘LOCATION=/dsk4/arch_sh

VALID_FOR=(ALL_LOGFILES,ALL_ROLES)

DB_UNIQUE_NAME=shdb‘

LOG_ARCHIVE_DEST_2=

‘SERVICE=bjdbASYNC //应该是对方

VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)

DB_UNIQUE_NAME=bjdb‘

LOG_ARCHIVE_DEST_STATE_1=ENABLE

LOG_ARCHIVE_DEST_STATE_2=ENABLE

LOG_ARCHIVE_MAX_PROCESSES=3

FAL_SERVER=bjdb

DB_FILE_NAME_CONVERT=‘/u01/app/oracle/oradata/TestDB12‘,‘/u01/app/oracle/oradata/sh‘ //先对方，后自己

LOG_FILE_NAME_CONVERT=

‘/dsk1/oradata/bj‘,‘/dsk1/oradata/sh‘,‘/dsk2/oradata/bj‘,‘/dsk2/oradata/sh‘

STANDBY_FILE_MANAGEMENT=AUTO //先对方，后自己

參考例子：

*.audit_file_dest=‘/u01/app/oracle/admin/sh/adump‘

*.audit_trail=‘db‘

*.compatible=‘11.2.0.0.0‘

*.control_files=‘/u01/app/oracle/oradata/sh/sh_control01.ctl‘

*.db_block_size=8192

*.db_name=‘TestDB12‘

*.db_recovery_file_dest=‘/u01/app/oracle/fast_recovery_area‘

*.db_recovery_file_dest_size=4322230272

*.diagnostic_dest=‘/u01/app/oracle‘

*.log_archive_format=‘arch_%t_%s_%r.log‘

*.memory_target=642006528

*.open_cursors=300

*.processes=150

*.remote_login_passwordfile=‘EXCLUSIVE‘

*.undo_tablespace=‘UNDOTBS1‘

DB_UNIQUE_NAME=shdb

LOG_ARCHIVE_CONFIG=‘DG_CONFIG=(bjdb,shdb)‘

LOG_ARCHIVE_DEST_1=

‘LOCATION=/dsk4/arch_sh

VALID_FOR=(ALL_LOGFILES,ALL_ROLES)

DB_UNIQUE_NAME=shdb‘

LOG_ARCHIVE_DEST_2=

‘SERVICE=bjdbASYNC

VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)

DB_UNIQUE_NAME=bjdb‘

LOG_ARCHIVE_DEST_STATE_1=ENABLE

LOG_ARCHIVE_DEST_STATE_2=ENABLE

LOG_ARCHIVE_MAX_PROCESSES=3

FAL_SERVER=bjdb

DB_FILE_NAME_CONVERT=‘/u01/app/oracle/oradata/TestDB12‘,‘/u01/app/oracle/oradata/sh‘

LOG_FILE_NAME_CONVERT=

‘/dsk1/oradata/bj‘,‘/dsk1/oradata/sh‘,‘/dsk2/oradata/bj‘,‘/dsk2/oradata/sh‘

STANDBY_FILE_MANAGEMENT=AUTO

2、主库-启备库前主库备份

备库启动之前。给主库做一个备份。

注意：DG下。养成在启动备库前为主库做备份的习惯。以供应对启动备库后产生的未知情况。

主库处于mount状态下：

SQL>selectstatus from v$instance;

技术分享

$mkdir/dsk4/backup

$rmantarget /

技术分享

RMAN> backupdatabase format ‘/dsk4/backup/%d_%s.bak‘;

技术分享

3、主库、备库-网络配置

主库下：

$ lsnrctlstart //启动监听

$cd/u01/app/oracle/product/11.2.0/dbhome_1/network/admin

$ vilistener.ora

# listener.oraNetwork Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

# Generated byOracle configuration tools.

LISTENER =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.71)(PORT = 1521))

)

ADR_BASE_LISTENER =/u01/app/oracle

$vi tnsnames.ora //手工创建tnsnames文件

# tnsnames.oraNetwork Configuration File:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora

# Generated byOracle configuration tools.

bjdb =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.4.71)(PORT = 1521))

(CONNECT_DATA =http://www.mamicode.com/

(SERVER = DEDICATED)

(SERVICE_NAME =bjdb)

)

shdb =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.4.72)(PORT = 1521))

(CONNECT_DATA =http://www.mamicode.com/

(SERVER = DEDICATED)

(SERVICE_NAME = shdb)

)

备库下：

$ lsnrctlstart //启动监听

$cd/u01/app/oracle/product/11.2.0/dbhome_1/network/admin

$ vilistener.ora //编辑监听

# listener.oraNetwork Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora

# Generated byOracle configuration tools.

LISTENER =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.6.72)(PORT = 1521))

)

ADR_BASE_LISTENER =/u01/app/oracle

$vi tnsnames.ora //手工创建tnsnames文件

BJDB =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.4.71)(PORT = 1521))

)

(CONNECT_DATA = http://www.mamicode.com/(SERVER = DEDICATED)

(SERVICE_NAME = bjdb)

)

SHDB =

(DESCRIPTION =

(ADDRESS_LIST =

(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.4.72)(PORT = 1521))

)

(CONNECT_DATA = http://www.mamicode.com/(SERVER = DEDICATED)

(SERVICE_NAME = shdb)

)

4、备库-网络測试：

$sqlplussys/oracle@bjdb as sysdba

技术分享

【补充】：oraclepassword改动

若oraclepassword未知。能够例如以下改动oraclepassword：

$cd /u01/app/oracle/product/11.2.0/dbhome_1/dbs

$orapwd file=orapwTestDB12 password=oracle entries=3 force=y

$scp orapwTestDB12 shsrv:$ORACLE_HOME/dbs/orapwshdb

//把主库改动完的password文件复制到备库中

技术分享

SQL>showparameter name

技术分享

主库监听状态：

$lsnrctlstatus

技术分享

备库监听状态：

$lsnrctlstatus

技术分享

測试主库是否能ping通备库

$ tnsping shdb

技术分享

备库启动实例

$exportORACLE_SID=shdb

//或改动.bash_profile

$sqlplus ‘/assysdba’

SQL>startupnomount;

SQL>showparameter pfile; //备库使用pfile启动

技术分享

SQL>showparameter name。 //看一下数据库參数是否正确

技术分享

SQL>showparameter archive； //查询一下归档设置是否正确

技术分享
