DATA guard 搭建内容
主库通过网络把日志文件传输到副库
实现原理：主库是好的，副库安装数据库软件
oracle软件目录 /u01/app/oraI
查看环境变量 env|grep ORACLE
ps -ef|grep smon
v$database 反应的是控制文件信息
搭建DG必须开归档模式
开启快速恢复区：
默认路径db_recovery_file_dest /u01/app/oracle/fast_recovery_area
大小 db_recovery_file_dest_size 4977m
如果没开启，先设置大小，在设置路径
log_archive_dest_数字 配置归档目的地 最大31个
oracle默认能在这31个文件设置归档
如果没配置归档目的地，oracle将归档日志放在快速恢复区中
查看是否开启归档是否使用快速恢复区 archive log list
检索视图
select log_mode,force_logging from v$database;
alter database force logging;
define _editor=vim
edit liushuwei.sql ---简写ed liushuwei
oerr ora 17628
select SEQUENCE#,applied from v$archived_log;
SELECT * FROM V$MANAGED_STANDBY
DG三种保护模式：
最高可用性，最大保护，最高性能（企业常用）
备库分为，物理和逻辑
物理备库：recover技术 mount状态（可以得到完成主库的备份）11g特性 ADG（活动的DG）---由mount状态变为readonly状态 实现主备的读写分离
逻辑备库：logminer技术（数据挖掘）主库的备份转回为sql语句 open状态
DATA 搭建步骤
1.主库操作
1.1配置强制日志模式和归档：
[oracle@edbjr2p1 ~]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on Sun Apr 30 17:52:58 2017
Copyright (c) 1982, 2011, Oracle. All rights reserved.
Connected to:
Oracle Database 11g Enterprise Edition Release 11.2.0.3.0 - Production
With the Partitioning, OLAP, Data Mining and Real Application Testing options
SYS@PROD1> select log_mode,force_logging from v$database;
LOG_MODE FOR
------------ ---
ARCHIVELOG NO
SYS@PROD1> alter database force logging;
Database altered.
SYS@PROD1> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST

Next log sequence to archive 31
Current log sequence 31
SYS@PROD1> show parameter db_recovery
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
db_recovery_file_dest string /home/oracle/flash
db_recovery_file_dest_size big integer 4G
SYS@PROD1> alter system switch logfile;
System altered.
1.2 创建Standby logfile：
SYS@PROD1> ed1
alter database add standby logfile group 4 (‘/u01/app/oracle/oradata/PROD1/stlog01.log‘) size 100m;
alter database add standby logfile group 5 (‘/u01/app/oracle/oradata/PROD1/stlog02.log‘) size 100m;
alter database add standby logfile group 6 (‘/u01/app/oracle/oradata/PROD1/stlog03.log‘) size 100m;
alter database add standby logfile group 7 (‘/u01/app/oracle/oradata/PROD1/stlog04.log‘) size 100m;
SYS@PROD1> @1
Database altered.
Database altered.
Database altered.
Database altered.
1.3 创建参数文件：
SYS@PROD1> create pfile from spfile;
File created.
1.4 修改参数文件：
[oracle@edbjr2p1 ~]$ cd $ORACLE_HOME/dbs
[oracle@edbjr2p1 dbs]$ vi initPROD1.ora
DB_NAME=PROD1
DB_UNIQUE_NAME=PROD1
LOG_ARCHIVE_CONFIG=‘DG_CONFIG=(PROD1,SBDB1)‘
LOG_ARCHIVE_DEST_1=
‘LOCATION=use_db_recovery_file_dest
VALID_FOR=(ALL_LOGFILES,ALL_ROLES)
DB_UNIQUE_NAME=PROD1‘
LOG_ARCHIVE_DEST_2=
‘SERVICE=SBDB1 ASYNC
VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE)
DB_UNIQUE_NAME=SBDB1‘
LOG_ARCHIVE_DEST_STATE_1=ENABLE
LOG_ARCHIVE_DEST_STATE_2=ENABLE
REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE
LOG_ARCHIVE_FORMAT=%t_%s_%r.arc
FAL_SERVER=SBDB1
DB_FILE_NAME_CONVERT=‘SBDB1‘,‘PROD1‘
LOG_FILE_NAME_CONVERT=‘SBDB1‘,‘PROD1‘
STANDBY_FILE_MANAGEMENT=AUTO
dg_broker_start=true
1.5 修改监听文件：
[oracle@edbjr2p1 dbs]$ vi ../network/admin/listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = edbjr2p1.example.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
ADR_BASE_LISTENER = /u01/app/oracle
SID_LIST_LISTENER=
(SID_LIST=
(SID_DESC=
(GLOBAL_DBNAME=PROD1.us.oracle.com)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME=PROD1))
(SID_DESC=
(GLOBAL_DBNAME=PROD1_DGMGRL.us.oracle.com)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME=PROD1))
(SID_DESC=
(SID_NAME=plsextproc)
(ORACLE_HOME=/u01/app/oracle/product/11.2.0/dbhome_1)
(PROGRAM=extproc)))
[oracle@edbjr2p1 dbs]$ vi ../network/admin/tnsnames.ora
##添加上如下内容
SBDB1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = edbjr2p2.example.com)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = SBDB1.us.oracle.com)
)
)
1.6 传输文件到备库主机：
[oracle@edbjr2p1 dbs]$ scp initPROD1.ora edbjr2p2:/u01/app/oracle/product/11.2.0/db_1/dbs/initSBDB1.ora
oracle@edbjr2p2‘s password:

[oracle@edbjr2p1 dbs]$ scp orapwPROD1 edbjr2p2:/u01/app/oracle/product/11.2.0/db_1/dbs/orapwSBDB1
oracle@edbjr2p2‘s password:
orapwPROD1 100% 1536 1.5KB/s 00:00
[oracle@edbjr2p1 dbs]$ scp ../network/admin/listener.ora ../network/admin/tnsnames.ora edbjr2p2:/u01/app/oracle/product/11.2.0/db_1/network/admin
oracle@edbjr2p2‘s password:
listener.ora 100% 837 0.8KB/s 00:00
tnsnames.ora 100% 1971 1.9KB/s 00:00
1.7 重启主库使配置生效：
[oracle@edbjr2p1 dbs]$ sqlplus / as sysdba

2.备库操作
2.1 创建对应路径：
[oracle@edbjr2p2 ~]$ cd /u01/app/oracle/
[oracle@edbjr2p2 oracle]$ mkdir -p admin/SBDB1/adump
[oracle@edbjr2p2 oracle]$ mkdir -p oradata/SBDB1
[oracle@edbjr2p2 dbs]$ mkdir -p /home/oracle/flash
2.2 修改参数文件：
[oracle@edbjr2p2 oracle]$ cd $ORACLE_HOME/dbs
[oracle@edbjr2p2 dbs]$ vi initSBDB1.ora #追加到
DB_NAME=PROD1
DB_UNIQUE_NAME=SBDB1 # 区分主备
LOG_ARCHIVE_CONFIG=‘DG_CONFIG=(SBDB1,PROD1)‘ # 数据库名，主|备
LOG_ARCHIVE_DEST_1= # 本地归档

LOG_ARCHIVE_DEST_STATE_1=ENABLE # 表示归档目的地可用
LOG_ARCHIVE_DEST_STATE_2=ENABLE
REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE # 远程登陆
LOG_ARCHIVE_FORMAT=%t_%s_%r.arc # 归档日志格式 使用快速恢复区时（自己管理），此参数无效。
FAL_SERVER=PROD1 # 获取归档日志的服务器 备库使用参数1
DB_FILE_NAME_CONVERT=‘PROD1‘,‘SBDB1‘ # 日志名转换时 后面的替换前面的，可有多项 1替2，3替4等; 2
LOG_FILE_NAME_CONVERT=‘PROD1‘,‘SBDB1‘ # 3
STANDBY_FILE_MANAGEMENT=AUTO # 4
dg_broker_start=true
2.3 修改网络配置文件：
[oracle@edbjr2p2 dbs]$ vi ../network/admin/listener.ora
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = edbjr2p2.example.com)(PORT = 1521))

3.搭建备库：
3.1 使用复制数据库技术搭建备库：
[oracle@edbjr2p1 ~]$ rman target / auxiliary sys/oracle@sbdb1 # 主库操作，主库@备库
Recovery Manager: Release 11.2.0.3.0 - Production on Sun Apr 30 18:17:30 2017
Copyright (c) 1982, 2011, Oracle and/or its affiliates. All rights reserved.
connected to target database: PROD1 (DBID=2082231315)
connected to auxiliary database: PROD1 (not mounted)
# 批处理命令，连续操作需清空之前数据
RMAN> DUPLICATE TARGET DATABASE # 复制目标库
FOR STANDBY # standby 表复制为备库
FROM ACTIVE DATABASE #
DORECOVER # 应用归档
NOFILENAMECHECK; # 文件名检查，同台机器需检查，不同的，异地不检查
3.2 使用broker管理DG：
[oracle@edbjr2p1 ~]$ dgmgrl /
DGMGRL for Linux: Version 1
