二、主库操作
2.1 修改forcelogging、开闪回
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$database; |
2.2 添加standby log
1 2 3 4 5 6 7 | select * from v$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
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
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
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
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
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
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
