一、主庫打開forcelogging

startup mount;

alter database force logging;

二、主 ?備 庫配置監聽

主：listener.oraSID_LIST_LISTENER?=?(SID_LIST?=??????(SID_DESC?=?????????????(GLOBAL_DBNAME?=?primary)?????????????(ORACLE_HOME?=?/u01/app/oracle/product/11.2.0/db_1)????????(SID_NAME?=?primary)?????????))???LISTENER?=??(DESCRIPTION_LIST?=????(DESCRIPTION?=??????(ADDRESS?=?(PROTOCOL?=?IPC)(KEY?=?EXTPROC1521))??????(ADDRESS?=?(PROTOCOL?=?TCP)(HOST?=?primary)(PORT?=?1521))????)??)??備：listener.oraSID_LIST_LISTENER?=?(SID_LIST?=??????(SID_DESC?=?????????????(GLOBAL_DBNAME?=?standby)?????????????(ORACLE_HOME?=?/u01/app/oracle/product/11.2.0/db_1)????????(SID_NAME?=?standby)?????????))???LISTENER?=??(DESCRIPTION_LIST?=????(DESCRIPTION?=??????(ADDRESS?=?(PROTOCOL?=?IPC)(KEY?=?EXTPROC1521))??????(ADDRESS?=?(PROTOCOL?=?TCP)(HOST?=?standby)(PORT?=?1521))????)??)??主、備：tnsnames.oraPRIMARY?=??(DESCRIPTION?=????(ADDRESS?=?(PROTOCOL?=?TCP)(HOST?=?primary)(PORT?=?1521))????(CONNECT_DATA?=??????(SERVER?=?DEDICATED)??????(SERVICE_NAME?=?primary)????)??)?STANDBY?=??(DESCRIPTION?=????(ADDRESS?=?(PROTOCOL?=?TCP)(HOST?=?standby)(PORT?=?1522))????(CONNECT_DATA?=??????(SERVER?=?DEDICATED)??????(SERVICE_NAME?=?standby)????)??)

三、主庫配置DG參數

配置spfile信息

alter system set db_name='primary' scope=spfile;

-- 主備db_name必須一致;

alter system set db_unique_name='primary' scope=spfile;

alter system set log_archive_config='DG_CONFIG=(primary,standby)' scope=spfile;

alter system set log_archive_dest_1='LOCATION=/u01/app/oracle/fast_recovery_area valid_for=(all_logfiles,all_roles) db_unique_name=primary' ?scope=spfile;

alter system set log_archive_dest_2='SERVICE=standby lgwr sync valid_for=(online_logfiles,primary_role) db_unique_name=standby' scope=spfile;

--注意每一個=前后均不能有空格，否則報錯;

alter system set LOG_ARCHIVE_DEST_STATE_1=ENABLE;

alter system set LOG_ARCHIVE_DEST_STATE_2=ENABLE;

alter system set standby_file_management=AUTO scope=spfile;

alter system set log_archive_format='%t_%s_%r.arc' scope=spfile;

alter system set fal_server=primary scope=spfile;--11g中fal參數已被廢除，fal-fetch archivelog 進程，一般情況下看不到此進程；

alter system set fal_client=standby scope=spfile;

?

shutdown abort;

startup;

?

四、主 備 庫創建密碼文件【一 至 四 保證主庫處于mount或者以下】

orapwd?file=orapw$ORACLE_SID?password=redhat?entries=5??--主庫orapwd?file=orapw$ORACLE_SID?password=redhat?entries=5??--備庫

五、主庫手動創建pfile并傳到備庫

create pfile='/tmp/initstandby.ora' from spfile;

scp -r $ORACLE_BASE/admin/ ?$ORACLE_BASE/diag/ $ORACLE_BASE/oradata/ ?$ORACLE_BASE/fast_recovery_area/ standby:/$ORACLE_BASE

六、復制數據文件到備庫

scp?-r?$ORACLE_BASE/admin/??$ORACLE_BASE/diag/?$ORACLE_BASE/oradata/??$ORACLE_BASE/fast_recovery_area/?standby:/$ORACLE_BASE

說明：其實傳過去的數據，備庫并不使用。備庫使用的是主庫的目錄！

七、利用指定的pfile復制出來的spfile打開備庫到nomount狀態

create?spfile?from?pfile='$ORACLE_HOME/dbs/initstandby.ora'startup?nomount;

八、備庫創建相關配置參數

備庫配置

利用主庫傳過來的pfile啟動到nomount狀態，并配置如下：

?

create spfile from pfile='$ORACLE_HOME/dbs/initstandby.ora'

startup nomount;

alter system set db_name=primary scope=spfile;

alter system set db_unique_name=standby scope=spfile;

alter system set log_archive_config='DG_CONFIG=(primary,standby)' scope=spfile;

alter system set log_archive_dest_1='LOCATION=/u01/app/oracle/fast_recovery_area valid_for=(all_logfiles,all_roles) db_unique_name=standby' ?scope=spfile;

alter system set log_archive_dest_2='SERVICE=primary lgwr sync valid_for=(online_logfiles,primary_role) db_unique_name=primary' scope=spfile;

alter system set standby_file_management=AUTO scope=spfile;

alter system set log_archive_format='%t_%s_%r.arc' scope=spfile;

alter system set fal_server=standby scope=spfile; ?

alter system set fal_client=primary scope=spfile;

shutdown abort;

startup nomount;

create pfile from spfile;

九、主庫利用rman duplicate 創建備庫

rman?target?sys/redhat@primary?auxiliary?sys/redhat@standby?nocatalogduplicate?target?database?for?standby?from?active?database?nofilenamecheck;

十、查看備庫并open備庫

--備庫創建后會自動mount

alter database open；

十一、主 ?備 庫增加 standby 日志

a.先查看本地log大小以及路徑?select?a.bytes,a.members,b.status,b.member?from?v$log?a,v$logfile?b?where?a.group#=b.group#;?b.在primary/standby創建4組standby?logalter?database?add?standby?logfile?group?4?'/u01/app/oracle/oradata/primary/redo04.log'?size?50m?;alter?database?add?standby?logfile?group?5?'/u01/app/oracle/oradata/primary/redo05.log'?size?50m?;alter?database?add?standby?logfile?group?6?'/u01/app/oracle/oradata/primary/redo06.log'?size?50m;alter?database?add?standby?logfile?group?7?'/u01/app/oracle/oradata/primary/redo07.log'?size?50m;

十二、打開備庫實時應用日志，打開flashback功能

recover managed standby database using current logfile disconnect from session;

注意：

主庫的flashback on 可以在線打開；

備庫的flashback on必須按如下步驟操作：

SQL>?select?flashback_on?from?v$database;?FLASHBACK_ON------------------NO?SQL>?alter?database?recover?managed?standby?database?cancel;?Database?altered.?SQL>?alter?database?flashback?on;?Database?altered.?SQL>??alter?database?recover?managed?standby?database?disconnect?from?session;?Database?altered.?SQL>?select?flashback_on?from?v$database;?FLASHBACK_ON------------------YES

十三、相關測試

創建表空間以及相關數據，發現備庫秒看

至此11g物理DG配置完畢！
