樓主說一下你的具體步驟，才好幫你分析！uj5u.com熱心網友回復：
11支持ADG，參照官方檔案https://support.oracle.com/epmos/faces/DocumentDisplay?id=1580796.1
uj5u.com熱心網友回復：
我是按照檔案一步一步來的，我從來沒配過oracle主從。具體步驟是
2.設定主庫為歸檔模式：
SQL> archive log list
SQL> shutdown immediate
SQL> startup mount
SQL> alter database archivelog;
SQL> archive log list
3.檢查主機是否有口令檔案,如沒有需建立
orapwd file='/opt/oracle/product/10.2.0/dbs/orawdlottery.ora' password=sys entries=5
4.為主資料庫添加"備用聯機日志檔案"
SQL> alter database add standby logfile group 4
('/opt/oracle/oradata/lottery/redo04.log') size 50m;
SQL> alter database add standby logfile group 5
('/opt/oracle/oradata/lottery/redo05.log') size 50m;
SQL> alter database add standby logfile group 6
('/opt/oracle/oradata/lottery/redo06.log') size 50m;
SQL> alter database add standby logfile group 7
('/opt/oracle/oradata/lottery/redo07.log') size 50m;
5.修改主庫引數檔案
SQL> create pfile='/opt/oracle/admin/lottery/pfile/init.ora' from spfile;
lottery.__db_cache_size=100663296
lottery.__java_pool_size=4194304
lottery.__large_pool_size=4194304
lottery.__shared_pool_size=54525952
lottery.__streams_pool_size=0
*.audit_file_dest='/opt/oracle/admin/lottery/adump'
*.background_dump_dest='/opt/oracle/admin/lottery/bdump'
*.compatible='10.2.0.1.0'
*.control_files='/opt/oracle/oradata/lottery/control01.ctl','/opt/oracle/oradata/lottery/control02.ctl','/opt/oracle/oradata/lottery/control03.ctl'
*.core_dump_dest='/opt/oracle/admin/lottery/cdump'
*.db_block_size=8192
*.db_domain=''
*.db_file_multiblock_read_count=16
*.db_name='lottery'
*.db_recovery_file_dest='/opt/oracle/flash_recovery_area'
*.db_recovery_file_dest_size=2147483648
*.dispatchers='(PROTOCOL=TCP) (SERVICE=lotteryXDB)'
*.job_queue_processes=10
*.log_archive_format='%T%S%r.ARC'
*.log_archive_max_processes=3
*.open_cursors=300
*.pga_aggregate_target=16777216
*.processes=150
*.remote_login_passwordfile='EXCLUSIVE'
*.sga_target=167772160
*.undo_management='AUTO'
*.undo_tablespace='UNDOTBS1'
*.user_dump_dest='/opt/oracle/admin/lottery/udump'
#add below parameter for standy database
*.DB_UNIQUE_NAME='primary'
*.log_archive_config='DG_CONFIG=(primary,standby)'
*.log_archive_dest_1='location=/opt/oracle/oradata/lottery/archive/ VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=primary'
*.log_archive_dest_2='SERVICE=standby arch ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=standby'
*.STANDBY_FILE_MANAGEMENT=AUTO
*.LOG_ARCHIVE_DEST_STATE_1=ENABLE
*.LOG_ARCHIVE_DEST_STATE_2=ENABLE
*.FAL_SERVER='standby'
*.FAL_CLIENT='primary'
6.主庫用PFILE建立SPFILE
[oracle@host127 pfile]$ sqlplus '/ as sysdba'
SQL> create spfile from pfile='/opt/oracle/admin/lottery/pfile/init.ora';
7.建立備用庫的控制檔案
SQL> alter database create standby controlfile as '/tmp/standby_ctl01.ctl';
8.配置主資料庫listener及tnsnames
[oracle@host127 admin]$ cat listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = lottery)
(ORACLE_HOME = /opt/oracle/product/10.2.0)
(SID_NAME = lottery)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = host127)(PORT = 1521))
)
)
#加1522埠供以后做switchover
SID_LIST_LISTENER1 =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = lottery)
(ORACLE_HOME = /opt/oracle/product/10.2.0)
(SID_NAME = lottery)
)
)
LISTENER1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = host127)(PORT = 1522))
)
)
[oracle@host127 admin]$ cat tnsnames.ora
#1521和1522埠都能連上主機和備機，這樣在做switchover時就不需要改這里的設定了
primary =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.128)(PORT = 1522))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.127)(PORT = 1522))
)
(CONNECT_DATA =
(SID = lottery)
)
)
standby =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.127)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.128)(PORT = 1521))
)
(CONNECT_DATA =
(SID = lottery)
)
)
9.復制檔案到備機
[oracle@host128 ~]cd /opt/oracle/oradata/lottery
[oracle@host128 lottery]$rcp host127:/opt/oracle/oradata/lottery/*.dbf .
[oracle@host128 lottery]$rcp host127:/tmp/standby_ctl01.ctl .
[oracle@host128 lottery]$mv standby_ctl01.ctl control01.ctl
[oracle@host128 lottery]$cp control01.ctl control02.ctl
[oracle@host128 lottery]$cp control01.ctl control03.ctl
10.復制并修改備機的引數檔案
[oracle@host128 ~]cd /opt/oracle/admin/lottery/pfile
[oracle@host128 pfile]$rcp host127:/opt/oracle/admin/lottery/pfile/init.ora .
修改為如下：
lottery.__db_cache_size=100663296
lottery.__java_pool_size=4194304
lottery.__large_pool_size=4194304
lottery.__shared_pool_size=54525952
lottery.__streams_pool_size=0
*.audit_file_dest='/opt/oracle/admin/lottery/adump'
*.background_dump_dest='/opt/oracle/admin/lottery/bdump'
*.compatible='10.2.0.1.0'
*.control_files='/opt/oracle/oradata/lottery/control01.ctl','/opt/oracle/oradata/lottery/control02.ctl','/opt/oracle/oradata/lottery/control03.ctl'
*.core_dump_dest='/opt/oracle/admin/lottery/cdump'
*.db_block_size=8192
*.db_domain=''
*.db_file_multiblock_read_count=16
*.db_name='lottery'
*.db_recovery_file_dest='/opt/oracle/flash_recovery_area'
*.db_recovery_file_dest_size=2147483648
*.dispatchers='(PROTOCOL=TCP) (SERVICE=lotteryXDB)'
*.job_queue_processes=10
*.log_archive_format='%T%S%r.ARC'
*.log_archive_max_processes=3
*.open_cursors=300
*.pga_aggregate_target=16777216
*.processes=150
*.remote_login_passwordfile='EXCLUSIVE'
*.sga_target=167772160
*.undo_management='AUTO'
*.undo_tablespace='UNDOTBS1'
*.user_dump_dest='/opt/oracle/admin/lottery/udump'
*.DB_UNIQUE_NAME='standby'
*.log_archive_config='DG_CONFIG=(primary,standby)'
*.log_archive_dest_1='location=/opt/oracle/oradata/lottery/archive/ VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=standby'
*.log_archive_dest_2='SERVICE=primary arch ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=primary'
*.STANDBY_FILE_MANAGEMENT=AUTO
*.LOG_ARCHIVE_DEST_STATE_1=ENABLE
*.LOG_ARCHIVE_DEST_STATE_2=ENABLE
*.FAL_SERVER='primary'
*.FAL_CLIENT='standby'
11.生成備用庫密碼檔案
orapwd file='/opt/oracle/product/10.2.0/dbs/orawdlottery.ora' password=sys entries=5
12.修改備機的listener及tnsnames
[oracle@host128 admin]$ cat listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = lottery)
(ORACLE_HOME = /opt/oracle/product/10.2.0)
(SID_NAME = lottery)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = host128)(PORT = 1521))
)
)
#加一個1522的埠供以后做switchover
SID_LIST_LISTENER1 =
(SID_LIST =
)
(SID_DESC =
(GLOBAL_DBNAME = lottery)
(ORACLE_HOME = /opt/oracle/product/10.2.0)
(SID_NAME = lottery)
)
)
LISTENER1 =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = host128)(PORT = 1522))
)
)
[oracle@host128 admin]$ cat tnsnames.ora
primary =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.128)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.127)(PORT = 1521))
)
(CONNECT_DATA =
(SID = lottery)
)
)
standby =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.127)(PORT = 1522))
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.128)(PORT = 1522))
)
(CONNECT_DATA =
(SID = lottery)
)
)
13.測驗主備之間網路連通
[oracle@host127 admin]$ lsnrctl start
[oracle@host127 admin]$ tnsping standby
[oracle@host128 admin]$ lsnrctl start
[oracle@host128 admin]$ tnsping primary
14.打開備庫
SQL> startup mount pfile='/opt/oracle/admin/lottery/pfile/init.ora';
SQL> create spfile from pfile='/opt/oracle/admin/lottery/pfile/init.ora';
SQL> alter database recover managed standby database disconnect from session;
15.打開主庫
SQL> startup
16.測驗是否OK
主庫：
SQL> alter system switch logfile;
從庫：
SQL> select FIRST_TIME,NEXT_TIME, APPLIED,SEQUENCE# from v$archived_log order by SEQUENCE#;
