Oracle 19c DataGuard 实践
主库 dguard, IP 192.168.43.92
备库dguard2,IP 192.168.43.182
1. enable force logging on the primary database
SQL> select name,FORCE_LOGGING from v$database;
NAME FORCE_LOGGING
--------- ---------------------------------------
DGUARD NO
SQL> ALTER DATABASE FORCE LOGGING;
Database altered.
SQL> select name,FORCE_LOGGING from v$database;
NAME FORCE_LOGGING
--------- ---------------------------------------
DGUARD YES
2. enable archive log on the primary database
SQL> archive log list;
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 5
Current log sequence 7
SQL> shutdown immediate;
ORA-01109: database not open
Database dismounted.
ORACLE instance shut down.
SQL> startup mount;
ORACLE instance started.

SQL> alter database archivelog;

SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 5
Next log sequence to archive 7
Current log sequence 7
SQL> show parameter DB_RECOVERY_FILE_DEST;
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string /u01/app/fast_recovery_area
db_recovery_file_dest_size big integer 12732M
SQL> alter database open;
Database altered.
3. configure standby redo log files for the primary database( this is needed when the primary database change to standby database)
SQL> select group#, bytes/1024/1024 as mb_size from v$log;-- query current redo log file size as the standby redo log file size when the primary database change the redo log the standby database also change the standby redo log, normally we also need to add one more group to the standby redo log, standby is transfered from primary, then will apply the standby redo log to the standby database,all of them needs time, when primary key is done, the standby database standby redo log maybe still active, it will has impact to the primary database performance,here are 3 groups for redo group and 4 groups for standby redo
GROUP# MB_SIZE
---------- ----------
1 200
2 200
3 200
SQL>
SQL> ALTER DATABASE ADD STANDBY LOGFILE ('/u01/app/oradata/DGUARD/slog1.rdo') SIZE 200m;
Database altered.
SQL> ALTER DATABASE ADD STANDBY LOGFILE ('/u01/app/oradata/DGUARD/slog2.rdo') SIZE 200m;
Database altered.
SQL> ALTER DATABASE ADD STANDBY LOGFILE ('/u01/app/oradata/DGUARD/slog3.rdo') SIZE 200m;
Database altered.
SQL> ALTER DATABASE ADD STANDBY LOGFILE ('/u01/app/oradata/DGUARD/slog4.rdo') SIZE 200m;
Database altered.
4.配置 oracle listener 静态注册和TNS,允许远程打开或关闭数据库
主库LISTENER配置如下
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=dguard)
(SID_NAME=dguard)
(ORACLE_HOME=/u01/app/oracle/product/19.3.0/dbhome_1)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dguard)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCPS)(HOST = dguard)(PORT = 2484))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
主库 tnsnames配置
DGUARD =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.43.92)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dguard)
)
)
DGUARD2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.43.182)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dguard2)
)
)
LISTENER_DGUARD =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.43.92)(PORT = 1521))
备库 listener 配置如下
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=dguard2)
(SID_NAME=dguard2)
(ORACLE_HOME=/u01/app/oracle/product/19.3.0/dbhome_1)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = dguard2)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCPS)(HOST = dguard2)(PORT = 2484))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
备库TNSNAMES配置如下
DGUARD2 =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.43.182)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dguard2)
)
)
DGUARD =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.43.92)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = dguard)
)
)
LISTENER_DGUARD =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.43.182)(PORT = 1521))
5.将密码 文件从主库传送到备库
[oracle@dguard dbs]$ pwd
/u01/app/oracle/product/19.3.0/dbhome_1/dbs
[oracle@dguard dbs]$ scp orapwdguard oracle@dguard2:/u01/app/oracle/product/19.3.0/dbhome_1/dbs/orapwdguard2
oracle@dguard2's password:
orapwdguard 100% 2048 3.2MB/s 00:00
[oracle@dguard dbs]$
6. Modify pirmary database parameter,并重新启动主库
SQL> create pfile from spfile;
File created.
[oracle@localhost ~]$ cd $ORACLE_HOME/dbs
[oracle@localhost dbs]$ ls
[oracle@localhost dbs]$ vi initdguard.ora
请在文件默认的参数下面加上如下关于standbyde
*.DB_FILE_NAME_CONVERT='/u01/app/oradata/DGUARD','/u01/app/oradata/DGUARD/'
*.DB_UNIQUE_NAME='dguard'
*.FAL_SERVER='dguard2'
*.local_listener='LISTENER_DGUARD'--与TNS中配置相同
*.LOG_ARCHIVE_CONFIG='DG_CONFIG=(dguard,dguard2)'
*.LOG_ARCHIVE_DEST_1='LOCATION=USE_DB_RECOVERY_FILE_DEST
VALID_FOR=(ALL_LOGFILES,ALL_ROLES)
DB_UNIQUE_NAME=dguard'
*.LOG_ARCHIVE_DEST_2='SERVICE=dguard2 ASYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=dguard2'
*.LOG_ARCHIVE_FORMAT='%t_%s_%r.arc'
*.standby_file_management='MANUAL'---这个 参数开始必须为manual 不然后续做 RMAN DUPLICATE报错，调试完成后，在主库和备库上再调整为'AUTO'
*.LOG_FILE_NAME_CONVERT='/u01/app/oradata/DGUARD','/u01/app/oradata/DGUARD/'
*.REMOTE_LOGIN_PASSWORDFILE='EXCLUSIVE'
SQL> shutdown immediate;
Database closed.
Database dismounted.
ORACLE instance shut down.
SQL> create spfile from pfile;
File created.
SQL> startup
ORACLE instance started.

Database Buffers 637534208 bytes
Redo Buffers 7639040 bytes
Database mounted.
Database opened.
7.为备库创建audit目录
[oracle@dguard2 dbs]$ mkdir -p /u01/app/admin/dguard2/adump
8.简单创建standby database initdguar2.ora，并启动到NOMOUNT状态
[oracle@dguard2 dbs]$ pwd
/u01/app/oracle/product/19.3.0/dbhome_1/dbs
[oracle@dguard2 dbs]$ cp init.ora initdguard2.ora
[oracle@dguard2 dbs]$ vi initdguard2.ora
修改后所有参数如下
db_name='dguard'
db_unique_name='dguard2'
processes = 150
audit_file_dest='/u01/app/admin/dguard2/adump'
audit_trail ='db'
db_block_size=8192
db_domain=''
db_recovery_file_dest='/u01/app/fast_recovery_area'
db_recovery_file_dest_size=2G
diagnostic_dest='/u01/app/diag'
dispatchers='(PROTOCOL=TCP) (SERVICE=ORCLXDB)'
open_cursors=300
remote_login_passwordfile='EXCLUSIVE'
undo_tablespace='UNDOTBS1'
使用远程启动方式将备库启动到NOMOUNT 状态
[oracle@dguard2 dbs]$ sqlplus sys/Ntrvl#123@dguard2 as sysdba
SQL> startup nomount;
ORACLE instance started.

Variable Size 281018368 bytes
Database Buffers 50331648 bytes
Redo Buffers 7639040 bytes
9. 创建RMAN cmd file
[oracle@dguard admin]$ vi cmdfile.rmn#可以是你喜欢的任何名字，后续跑命令要一致
duplicate target database for standby from active database dorecover
spfile
set db_unique_name='dguard2'
set db_name='dguard'
set log_archive_config='DG_CONFIG=(dguard,dguard2)'
set fal_server='dguard'
set standby_file_management='MANUAL'
nofilenamecheck;
[oracle@dguard admin]$
10. 使用RMAN 运行cmdfile.rmn，可以是主库主机也可以是备库主机，因为我们早已经配置好了TNS
rman target sys/password@dguard auxiliary sys/password@dguard2 cmdfile=cmdfile.rmn
