ADG搭建系列之 11G RAC to Single DAT

发表于

「这是我参与11月更文挑战的第24天，活动详情查看：2021最后一次更文挑战」

一、环境准备

主机名 ip DB Version db_name db_unique_name
主库节点一 lucifer01 10.211.55.100 11.2.0.4 orcl orcl
主库节点二 lucifer02 10.211.55.101 11.2.0.4 orcl orcl
备库 luciferdg 10.211.55.110 11.2.0.4 orcl orcldg

Notes：

1、db_unique_name主备库不能相同。

2、db_name主备库需保持一致。

3、主备库DB版本需保持一致。

二、搭建过程

1、Oracle软件安装

主库一键安装：

1
2
3
bash复制代码./AllRacOracleSilent.sh -i 10.211.55.101 -n lucifer02 -o orcl -d 11g -rac Y -n1 lucifer01 -n2 lucifer02 -pb1 10.211.55.100 -pb2 10.211.55.101 -vi1 10.211.55.102 -vi2 10.211.55.103 -pi1 10.10.1.1 -pi2 10.10.1.2 -si 10.211.55.105 -sn lucifer-scan -cn lucifer-cluster -dd /dev/asm_data -od /dev/asm_ocr -puf eth0 -prf eth1

./AllRacOracleSilent.sh -i 10.211.55.100 -n lucifer01 -o orcl -d 11g -rac Y -n1 lucifer01 -n2 lucifer02 -pb1 10.211.55.100 -pb2 10.211.55.101 -vi1 10.211.55.102 -vi2 10.211.55.103 -pi1 10.10.1.1 -pi2 10.10.1.2 -si 10.211.55.105 -sn lucifer-scan -cn lucifer-cluster -dd /dev/asm_data -od /dev/asm_ocr -puf eth0 -prf eth1

备库一键安装：（备库仅安装ORACLE软件，不建库）

1
bash复制代码./AllRacOracleSilent.sh -i 10.211.55.110 -n luciferdg -o orcl -d 11g -w Y

一键安装脚本可参考：ORACLE一键安装单机11G/12C/18C/19C并建库脚本

2、环境配置

a.配置hosts文件

主库：

bash复制代码##节点一
#dg
10.211.55.110 luciferdg

##节点二
#dg
10.211.55.110 luciferdg

备库：

bash复制代码##dg
10.211.55.100 lucifer01
10.211.55.101 lucifer02

sql复制代码set pagesize100
set line222
col member for a60
select * from v$logfile;
select * from v$log;
 
--需要注意：
--1.stanby log日志大小与redo log日志保持一致
--2.stanby log数量： 
standby logfile=(1+logfile组数)*thread=(1+3)*1=4组,需要加4组standby logfile.
--3.thread要与redo log保持一致，如果是rac，需要增加多个thread对应的standby log
 
ALTER DATABASE ADD STANDBY LOGFILE thread 1 
group 5 ('+DATA') SIZE 120M,
group 6 ('+DATA') SIZE 120M,
group 7 ('+DATA') SIZE 120M;

ALTER DATABASE ADD STANDBY LOGFILE thread 2
group 8 ('+DATA') SIZE 120M,
group 9 ('+DATA') SIZE 120M,
group 10 ('+DATA') SIZE 120M;

select * from v$standby_log;

f.备库开启到nomount状态

allocate channel prmy2 type disk;
allocate auxiliary channel aux1 type disk;
allocate auxiliary channel aux2 type disk;
DUPLICATE TARGET DATABASE FOR STANDBY FROM ACTIVE DATABASE DORECOVER NOFILENAMECHECK;
}

##主库设置DG参数
ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(ORCL,ORCLDG)';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=+DATA VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=ORCL';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=orcldg LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=ORCLDG';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE;
ALTER SYSTEM SET LOG_ARCHIVE_FORMAT='%t_%s_%r.arc' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_ARCHIVE_MAX_PROCESSES=4;
ALTER SYSTEM SET REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE SCOPE=SPFILE;
ALTER SYSTEM SET FAL_SERVER=ORCLDG;
ALTER SYSTEM SET FAL_CLIENT=ORCL;
ALTER SYSTEM SET DB_FILE_NAME_CONVERT='/oradata','+DATA' SCOPE=SPFILE;
ALTER SYSTEM SET LOG_FILE_NAME_CONVERT='/oradata','+DATA'  SCOPE=SPFILE;
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO;

4、备库开启日志应用

DATABASE_ROLE    OPEN_MODE
---------------- --------------------
PHYSICAL STANDBY READ ONLY WITH APPLY
 
SQL> SELECT protection_mode FROM v$database;
 
PROTECTION_MODE
--------------------
MAXIMUM PERFORMANCE

5、主库开启LOG_ARCHIVE_DEST_STATE_2
