linux下oracle11G DG搭建（三）：环绕备库搭建操作
环境

软件版本号 |
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
$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;
$mkdir/dsk4/backup
$rmantarget /
RMAN> backupdatabase format ‘/dsk4/backup/%d_%s.bak‘;
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 =
(SERVER = DEDICATED)
(SERVICE_NAME =bjdb)
)
)
shdb =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.4.72)(PORT = 1521))
(CONNECT_DATA =
(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 = (SERVER = DEDICATED)
(SERVICE_NAME = bjdb)
)
)
SHDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.4.72)(PORT = 1521))
)
(CONNECT_DATA = (SERVER = DEDICATED)
(SERVICE_NAME = shdb)
)
)
4、备库-网络測试：
$sqlplussys/[email protected] as sysdba
【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
SQL>showparameter name
主库监听状态：
$lsnrctlstatus
备库监听状态：
$lsnrctlstatus
測试主库是否能ping通备库
$ tnsping shdb
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
SQL>showparameter name。 //看一下数据库參数是否正确
SQL>showparameter archive； //查询一下归档设置是否正确
