Oracle Dataguard (the main library is Oracle rac cluster) configuration tutorial (02) - related operations of the Oracle RAC main library
/
This column explains in detail the configuration process of Oracle Dataguard (the Oracle version is 11g, and the main database is a two-node Oracle rac cluster). The main contents include:
(1) The installation of dataguard server Oracle software.
(2) Configuration of Oracle RAC main library and Dataguard server.
(3) Master-slave synchronization test.

- 1. Set the Oracle RAC main library to Force Logging mode and archive mode
- 2. Perform RMAN full backup operation on the Oracle RAC main library
-
-
- 1. Add a disk on node 1 of the Oracle RAC main library to store backup files
- 3. Perform RMAN full backup operation on the Oracle RAC main library
- 4. Create a physical standby database control file in the Oracle RAC main database
- 5. Create a physical standby database initialization parameter file in the Oracle RAC main database
- 6. Modify the password file in the Oracle RAC master library so that the SYS user passwords of both nodes are oracle
-
1. Set the Oracle RAC main library to Force Logging mode and archive mode
1. Check whether the Oracle RAC main library is in archive mode and Force Logging mode
SQL> select name,open_mode,log_mode,force_logging from v$database;
NAME OPEN_MODE LOG_MODE FOR
--------- -------------------- ------------ ---
HISDB READ WRITE NOARCHIVELOG NO
2. Set the Oracle RAC main library to Force Logging mode
SQL> alter database force logging;
Database altered.
SQL> select name,open_mode,log_mode,force_logging from v$database;
NAME OPEN_MODE LOG_MODE FOR
--------- -------------------- ------------ ---
HISDB READ WRITE NOARCHIVELOG YES
3. Set the Oracle RAC main library to archive mode
Setting the database to archive mode requires stopping the database, and then starting the database to mount state.
(1) Parking
# 切换到grid用户
# 查看数据库
[grid@rac1 ~]$ srvctl status database -d hisdb;
Instance hisdb1 is running on node rac1
Instance hisdb2 is running on node rac2
# 停库
[grid@rac1 ~]$ srvctl stop database -d hisdb;
# 查看数据库
[grid@rac1 ~]$ srvctl status database -d hisdb;
Instance hisdb1 is not running on node rac1
Instance hisdb2 is not running on node rac2
(2) Switch to the Oracle user, start the database to the mount state (just operate on any node)
SQL> startup mount;
ORACLE instance started.

(3) Start the database
--停库
SQL> shutdown immediate;
ORA-01109: database not open
Database dismounted.
ORACLE instance shut down.
-- 切换到grid用户
-- 启动数据库
[grid@rac1 ~]$ srvctl start database -d hisdb;
[grid@rac1 ~]$ srvctl status database -d hisdb;
Instance hisdb1 is running on node rac1
Instance hisdb2 is running on node rac2
2. Perform RMAN full backup operation on the Oracle RAC main library
1. Add a disk on node 1 of the Oracle RAC main library to store backup files
Add a disk on node 1 of the Oracle RAC main library, with a size of 10GB, and mount it to the directory /rman_backup; add a disk on the dataguard server, with a size of 10GB, and mount it to the directory/rman_backup. Write the database backup file of the Oracle RAC main library into the /rman_backup directory. It is then used to restore the database by copying the backup file to the /rman_backup directory of the dataguard server.
Perform the following operations on node 1 of the Oracle RAC main library:
(1) Add a disk on node 1 of the Oracle RAC main library
