二、主库操作

2.1 修改forcelogging、开闪回

alter database force logging; alter database flashback on; select name , open_mode, log_mode,force_logging,DATABASE_ROLE,switchover_status from v$database;

1 2 3

alter database force logging; alter database flashback on; select name , open_mode, log_mode,force_logging,DATABASE_ROLE,switchover_status from v$database;

2.2 添加standby log

select * from v$standby_log; select group#,bytes/1024/1024 ||'M' from v$log ; SELECT * FROM V$LOGFILE; alter database add standby logfile group 4 ('/u01/app/oracle/oradata/LHR11G/standby_redo04.log') size 50m; alter database add standby logfile group 5 ('/u01/app/oracle/oradata/LHR11G/standby_redo05.log') size 50m; alter database add standby logfile group 6 ('/u01/app/oracle/oradata/LHR11G/standby_redo06.log') size 50m;

1 2 3 4 5 6 7

select * from v$standby_log; select group#,bytes/1024/1024 ||'M' from v$log ; SELECT * FROM V$LOGFILE;   alter database add standby logfile group 4 ('/u01/app/oracle/oradata/LHR11G/standby_redo04.log') size 50m; alter database add standby logfile group 5 ('/u01/app/oracle/oradata/LHR11G/standby_redo05.log') size 50m; alter database add standby logfile group 6 ('/u01/app/oracle/oradata/LHR11G/standby_redo06.log') size 50m;

2.3 修改参数

alter system set db_unique_name='LHR11G' scope=spfile; alter system set log_archive_config='DG_CONFIG=(LHR11G,LHR11GDG)'; alter system set log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST db_unique_name=LHR11G valid_for=(ALL_LOGFILES,ALL_ROLES)'; alter system set log_archive_dest_2='SERVICE=LHR11GDG LGWR ASYNC db_unique_name=LHR11GDG valid_for=(ONLINE_LOGFILES,PRIMARY_ROLE)'; alter system set log_archive_dest_state_1=ENABLE; alter system set log_archive_dest_state_2=ENABLE; alter system set log_archive_max_processes=4; alter system set remote_login_passwordfile='EXCLUSIVE' scope=spfile; alter system set db_file_name_convert='LHR11GDG','LHR11G' scope=spfile; alter system set log_file_name_convert='LHR11GDG','LHR11G' scope=spfile; alter system set standby_file_management='AUTO'; alter system set fal_server='LHR11GDG'; alter system set fal_client='LHR11G'; startup force

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

alter system set db_unique_name='LHR11G' scope=spfile;   alter system set log_archive_config='DG_CONFIG=(LHR11G,LHR11GDG)';   alter system set log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST db_unique_name=LHR11G valid_for=(ALL_LOGFILES,ALL_ROLES)';   alter system set log_archive_dest_2='SERVICE=LHR11GDG LGWR ASYNC db_unique_name=LHR11GDG valid_for=(ONLINE_LOGFILES,PRIMARY_ROLE)';   alter system set log_archive_dest_state_1=ENABLE;   alter system set log_archive_dest_state_2=ENABLE;   alter system set log_archive_max_processes=4;   alter system set remote_login_passwordfile='EXCLUSIVE' scope=spfile;     alter system set db_file_name_convert='LHR11GDG','LHR11G' scope=spfile;   alter system set log_file_name_convert='LHR11GDG','LHR11G' scope=spfile;   alter system set standby_file_management='AUTO';   alter system set fal_server='LHR11GDG';   alter system set fal_client='LHR11G';   startup force

2.4 修改监听

vi /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/listener.ora SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = LHR11G) (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1) (SID_NAME= LHR11G) ) (SID_DESC = (GLOBAL_DBNAME = LHR11G_dgmgrl) (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1) (SID_NAME= LHR11G) ) )

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

vi  /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/listener.ora   SID_LIST_LISTENER = (SID_LIST =   (SID_DESC =     (GLOBAL_DBNAME = LHR11G)     (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1)     (SID_NAME= LHR11G)   )   (SID_DESC =     (GLOBAL_DBNAME = LHR11G_dgmgrl)     (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1)     (SID_NAME= LHR11G)   ) )

2.5 修改tnsnames.ora

vi /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/tnsnames.ora LHR11G = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.68.68)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = LHR11G) ) ) LHR11GDG = (DESCRIPTION = (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.68.69)(PORT = 1521)) (CONNECT_DATA = (SERVER = DEDICATED) (SERVICE_NAME = LHR11GDG) ) )

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

vi  /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/tnsnames.ora LHR11G =   (DESCRIPTION =     (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.68.68)(PORT = 1521))     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME = LHR11G)     )   )   LHR11GDG =   (DESCRIPTION =     (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.68.69)(PORT = 1521))     (CONNECT_DATA =       (SERVER = DEDICATED)       (SERVICE_NAME = LHR11GDG)     )   )

三、主库密码文件、tnsnames.ora拷贝到备库

docker cp LHR11G:/u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/orapwLHR11G . docker cp orapwLHR11G LHR11GDG:/u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/orapwLHR11GDG chown oracle.oinstall /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/orapwLHR11GDG docker cp LHR11G:/u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/tnsnames.ora . docker cp tnsnames.ora LHR11GDG:/u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/tnsnames.ora chown oracle.oinstall /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/tnsnames.ora

1 2 3 4 5 6 7 8

docker cp LHR11G:/u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/orapwLHR11G . docker cp orapwLHR11G LHR11GDG:/u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/orapwLHR11GDG chown oracle.oinstall /u01/app/oracle/product/11.2.0.4/dbhome_1/dbs/orapwLHR11GDG   docker cp LHR11G:/u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/tnsnames.ora . docker cp tnsnames.ora LHR11GDG:/u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/tnsnames.ora chown oracle.oinstall /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/tnsnames.ora

四、备库操作

4.1 修改监听

vi /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/listener.ora SID_LIST_LISTENER = (SID_LIST = (SID_DESC = (GLOBAL_DBNAME = LHR11GDG) (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1) (SID_NAME= LHR11GDG) ) (SID_DESC = (GLOBAL_DBNAME = LHR11GDG_dgmgrl) (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1) (SID_NAME= LHR11GDG) ) )

1 2 3 4 5 6 7 8 9 10 11 12 13 14

vi  /u01/app/oracle/product/11.2.0.4/dbhome_1/network/admin/listener.ora SID_LIST_LISTENER = (SID_LIST =   (SID_DESC =     (GLOBAL_DBNAME = LHR11GDG)     (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1)     (SID_NAME= LHR11GDG)   )   (SID_DESC =     (GLOBAL_DBNAME = LHR11GDG_dgmgrl)     (ORACLE_HOME = /u01/app/oracle/product/11.2.0.4/dbhome_1)     (SID_NAME= LHR11GDG)   ) )

4.2 备库修改到NOMOUNT状态

mkdir -p /u01/app/oracle/oradata/LHR11GDG/ mkdir -p /u01/app/oracle/admin/LHR11GDG/adump echo "db_name=LHR11G" > $ORACLE_HOME/dbs/initLHR11GDG.ora export ORACLE_SID=LHR11GDG sas startup nomount

1 2 3 4 5 6 7 8 9

mkdir -p /u01/app/oracle/oradata/LHR11GDG/ mkdir -p /u01/app/oracle/admin/LHR11GDG/adump   echo "db_name=LHR11G" > $ORACLE_HOME/dbs/initLHR11GDG.ora   export ORACLE_SID=LHR11GDG sas startup nomount

4.3 duplicate复制搭建DG

rman target sys/lhr@LHR11G auxiliary sys/lhr@LHR11GDG duplicate target database for standby nofilenamecheck from active database DORECOVER spfile set db_unique_name='LHR11GDG' set log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST valid_for=(ALL_LOGFILES,ALL_ROLES) db_unique_name=LHR11GDG' set standby_file_management='AUTO' set fal_server='LHR11G' set fal_client='LHR11GDG' set control_files='/u01/app/oracle/oradata/LHR11GDG/control01.ctl' set db_file_name_convert='LHR11G','LHR11GDG' set log_file_name_convert='LHR11G','LHR11GDG' set audit_file_dest='/u01/app/oracle/admin/LHR11GDG/adump' set sga_max_size='346030080' ;

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18

rman target sys/lhr@LHR11G auxiliary sys/lhr@LHR11GDG   duplicate target database for standby  nofilenamecheck from active database DORECOVER spfile set db_unique_name='LHR11GDG' set log_archive_dest_1='LOCATION=USE_DB_RECOVERY_FILE_DEST  valid_for=(ALL_LOGFILES,ALL_ROLES) db_unique_name=LHR11GDG' set standby_file_management='AUTO' set fal_server='LHR11G' set fal_client='LHR11GDG' set control_files='/u01/app/oracle/oradata/LHR11GDG/control01.ctl' set db_file_name_convert='LHR11G','LHR11GDG' set log_file_name_convert='LHR11G','LHR11GDG' set audit_file_dest='/u01/app/oracle/admin/LHR11GDG/adump' set sga_max_size='346030080' ;
