1. Environmental information:
System:
Oracle-linux 5.7

Database version:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0-64bit Production
PL/SQL Release 11.2.0.3.0-production
CORE 11.2.0.3.0 Production
TNS for Linux:version 11.2.0.3.0-production
Nlsrtl Version 11.2.0.3.0-production

Main Library: 192.168.12.31 Sid:yoon Db_unique_name:yoon
Library: 192.168.12.231 Sid:yoon DB_UNIQUE_NAME:YOONDG

2. Check if DG is installed:
Sql> SELECT * from v$option where parameter = ' Oracle Data Guard ';
PARAMETER VALUE
-------------------- --------------------
Oracle Data Guard TRUE
True indicates that the installation can be configured or the appropriate software needs to be installed

3. Check whether the main library is open for archiving:
sql> archive log list;
Database log mode No Archive mode
Automatic Archival Disabled
Archive Destination Use_db_recovery_file_dest
Oldest online log sequence 4
Current Log sequence 6

4. Set the main library to archive mode:
sql> shutdown Immediate
Database closed.
Database dismounted.
ORACLE instance shut down.

Sql> Startup Mount
ORACLE instance started.

sql> ALTER DATABASE Archivelog;

Database altered.

sql> ALTER DATABASE open;

Database altered.

sql> archive log list;
Database Log Mode Archive mode
Automatic Archival Enabled
Archive Destination Use_db_recovery_file_dest
Oldest online log sequence 4
Next Log sequence to archive 6
Current Log sequence 6

5. Set the main library to force logging:
sql> ALTER DATABASE force logging;

Database altered.

6. Create Standy log files:
Sql> select Group#,member from V$logfile;

group# MEMBER
------- -----------------------------------
3/opt/oracle/oradata/yoon/redo03.log
2/opt/oracle/oradata/yoon/redo02.log
1/opt/oracle/oradata/yoon/redo01.log
Add to:
sql> ALTER DATABASE Add standby logfile Group 7 '/opt/oracle/oradata/yoon/standby07.log ' size 50m;

Database altered.

sql> ALTER DATABASE ADD standby logfile Group 8 '/opt/oracle/oradata/yoon/standby08.log ' size 50m;

Database altered.

sql> ALTER DATABASE ADD standby logfile Group 9 '/opt/oracle/oradata/yoon/standby09.log ' size 50m;

Database altered.

sql> ALTER DATABASE Add standby logfile Group of '/opt/oracle/oradata/yoon/standby10.log ' size 50m;

Database altered.

7. Create Standby Control File:
sql> shutdown Immediate

Sql> Startup Mount

sql> ALTER DATABASE create standby Controlfile as '/opt/oracle/oradata/yoon/standby_control01.ctl ';

Database altered.

Sql>alter database open;

8. Set Db_unique_name:
The default db_name and Db_unique_name are the same, and the main library is Yoon
In the Configuration DG, the primary and standby SIDs can be the same, but,db_unique_name cannot be the same, the standby is set to: YOONDG
Sql> Show parameter db_unique_name;

NAME TYPE VALUE
------------------------------------ ---------- ------------------------------
Db_unique_name String Yoon

-Note that although the default Db_unique_name and db_name are consistent, they need to be set explicitly, otherwise this parameter is not in SPFile
Sql> alter system set Db_unique_name=yoon Scope=spfile;

System altered.

9. Configure the main library Listener.ora:
# Listener.ora Network Configuration File:/opt/oracle/product/11.2.0/db_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

Sid_list_listener=
(Sid_list =
(Sid_desc =

(Oracle_home =/opt/oracle/product/11.2.0/db_1/)
(Sid_name = yoon)
)
)

LISTENER =
(Description_list =
(DESCRIPTION =

Adr_base_listener =/opt/oracle

Configure Tnsnames.ora
# Listener.ora Network Configuration File:/opt/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.

)
)

10, copy the main library Listener.ora and Tnsnames.ora to the repository modification
[Email protected] admin]# SCP listener.ora tnsnames.ora [email protected]:/opt/oracle/product/11.2.0/db_1/ network/admin/
