【测试】手工搭建DG
前言：（一）准备工作：
1.数据库要处于归档模式；
2.监听参数：local_listener 默认值为空--1521
3.关闭闪回（可能会触发数据库的bug，备库不能开闪回）
4.如果有外部表，外部表要删除。
（二）环境描述：
192.168.206.8 主库 ORA11GR2
192.168.206.9 备库 SBDB
一，将数据库处于归档模式：
SQL> alter database archivelog; Database altered. SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination /u01/app/oracle/product/11.2.0/dbhome_1/dbs/arch
Oldest online log sequence 5
Next log sequence to archive 7
Current log sequence 7
二，查看本地监听，默认值为空：
SQL> show parameter local_listener; NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
local_listener string
三，关闪回（可能会触发数据库bug，备库不能开闪回）
查看显示关闭：
SQL> select flashback_on from v$database; FLASHBACK_ON
------------------
NO
四，生成一个文本参数文件修改参数文件：
SQL> create pfile from spfile; File created. [oracle@host08 ~]$ cd $ORACLE_HOME/dbs
[oracle@host08 dbs]$ ls
hc_ORA11GR2.dat init.ora initORA11GR2.ora lkORA11GR2 orapwORA11GR2 spfileORA11GR2.ora
[oracle@host08 dbs]$ vi initORA11GR2.ora （将一下参数加入）
DB_NAME=ORA11GR2
DB_UNIQUE_NAME=ORA11GR2
LOG_ARCHIVE_CONFIG='DG_CONFIG=(ORA11GR2,SBDB)'
CONTROL_FILES='/u01/app/oracle/oradata/ORA11GR2/control01.ctl','/u01/app/oracle/oradata/ORA11GR2/control02.ctl'
LOG_ARCHIVE_DEST_1=
'LOCATION=/u01/arch1/ORA11GR2/
VALID_FOR=(ALL_LOGFILES,ALL_ROLES)
DB_UNIQUE_NAME=ORA11GR2'
LOG_ARCHIVE_DEST_2=
'SERVICE=SBDB ASYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=SBDB'
LOG_ARCHIVE_DEST_STATE_1=ENABLE
LOG_ARCHIVE_DEST_STATE_2=ENABLE
REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE
LOG_ARCHIVE_FORMAT=%t_%s_%r.arc
LOG_ARCHIVE_MAX_PROCESSES=30
FAL_SERVER=SBDB
DB_FILE_NAME_CONVERT='SBDB','ORA11GR2'
LOG_FILE_NAME_CONVERT=
'/u01/app/oracle/oradata/SBDB/','/u01/app/oracle/oradata/ORA11GR2/'
STANDBY_FILE_MANAGEMENT=AUTO
创建参数中涉及到的目录：
[oracle@host08 dbs]$ mkdir -p /u01/app/oracle/admin/ORA11GR2/adump
[oracle@host08 dbs]$ mkdir -p /u01/app/oracle/oradata/ORA11GR2/
[oracle@host08 dbs]$ mkdir -p /u01/app/oracle
[oracle@host08 dbs]$ mkdir -p /u01/app/oracle/oradata/ORA11GR2/
[oracle@host08 dbs]$ mkdir -p /u01/arch1/ORA11GR2/
[oracle@host08 dbs]$ mkdir -p /u01/app/oracle/oradata/SBDB/
[oracle@host08 dbs]$ mkdir -p /u01/app/oracle/oradata/ORA11GR2/
五，开启force logging
SQL> alter database FORCE LOGGING; Database altered. SQL> select FORCE_LOGGING from v$database; FOR
---
YES
六，查看日志文件及大小，并增加standby logfile：
SQL> select GROUP#,MEMBER from v$logfile;
GROUP# MEMBER
---------- --------------------------------------------------
3 /u01/app/oracle/oradata/ORA11GR2/redo03.log
2 /u01/app/oracle/oradata/ORA11GR2/redo02.log
1 /u01/app/oracle/oradata/ORA11GR2/redo01.log
SQL> alter database add standby logfile group 4('/u01/app/oracle/oradata/ORA11GR2/redo401_std.log','/u01/app/oracle/oradata/ORA11GR2/redo402_std.log') size 50M;
Database altered.

7 /u01/app/oracle/oradata/ORA11GR2/redo702_std.log
11 rows selected.
七，将主库参数文件和口令文件传给备库：
[oracle@host08 dbs]$ ls
hc_ORA11GR2.dat init.ora initORA11GR2.ora lkORA11GR2 orapwORA11GR2 spfileORA11GR2.ora [oracle@host08 dbs]$ scp initORA11GR2.ora orapwORA11GR2 192.168.206.9:/u01/app/oracle/product/11.2.0/dbhome_1/dbs
The authenticity of host '192.168.206.9 (192.168.206.9)' can't be established.
RSA key fingerprint is 3b:3d:b7:e2:77:91:2d:27:57:87:96:96:b6:56:d2:1e.
Are you sure you want to continue connecting (yes/no)? yes
Warning: Permanently added '192.168.206.9' (RSA) to the list of known hosts.
oracle@192.168.206.9's password:
initORA11GR2.ora 100% 1610 1.6KB/s 00:00
orapwORA11GR2 100% 1536 1.5KB/s 00:00
八，修改备库参数文件：（此时备库的DB_NAME 应该跟主库一致）
DB_NAME=ORA11GR2
DB_UNIQUE_NAME=SBDB
LOG_ARCHIVE_CONFIG='DG_CONFIG=(SBDB,ORA11GR2)'
CONTROL_FILES='/u01/app/oracle/oradata/SBDB/control01.ctl','/u01/app/oracle/oradata/SBDB/control02.ctl'
LOG_ARCHIVE_DEST_1=
'LOCATION=/u01/arch1/SBDB/
VALID_FOR=(ALL_LOGFILES,ALL_ROLES)
DB_UNIQUE_NAME=SBDB'
LOG_ARCHIVE_DEST_2=
'SERVICE=ORA11GR2 ASYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=ORA11GR2'
LOG_ARCHIVE_DEST_STATE_1=ENABLE
LOG_ARCHIVE_DEST_STATE_2=ENABLE
REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE
LOG_ARCHIVE_FORMAT=%t_%s_%r.arc
LOG_ARCHIVE_MAX_PROCESSES=30
FAL_SERVER=ORA11GR2
DB_FILE_NAME_CONVERT='ORA11GR2','SBDB'
LOG_FILE_NAME_CONVERT=
'/u01/app/oracle/oradata/ORA11GR2/','/u01/app/oracle/oradata/SBDB/'
STANDBY_FILE_MANAGEMENT=AUTO
九，创建参数中涉及到的目录：
[oracle@host09 dbs]$ mkdir -p /u01/app/oracle/admin/SBDB/adump
[oracle@host09 dbs]$ mkdir -p /u01/app/oracle/oradata/SBDB/
[oracle@host09 dbs]$ mkdir -p /u01/app/oracle
[oracle@host09 dbs]$ mkdir -p /u01/app/oracle/oradata/SBDB/
[oracle@host09 dbs]$ mkdir -p /u01/arch1/SBDB/
[oracle@host09 dbs]$ mkdir -p /u01/app/oracle/oradata/ORA11GR2/
[oracle@host09 dbs]$ mkdir -p /u01/app/oracle/oradata/SBDB/
十，配置网络监听：
主库：
①[oracle@host08 admin]$ vi listener.ora # listener.ora Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools. LISTENER =

(DESCRIPTION =

(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
) ADR_BASE_LISTENER = /u01/app/oracle SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=ORA11GR2)
(SID_NAME=ORA11GR2)

)
) ②[oracle@host08 admin]$ vi tnsnames.ora SBDB=

(ADDRESS=(PROTOCOL=TCP)(HOST=192.168.206.9)(PORT=1521))
(CONNECT_DATA=
(SERVER=DEDICATED)
(SERVICE_NAME=SBDB)
)
)
③查看状态并验证是否ping通：
LSNRCTL> status
