oracle 容灾执行过程及问题分析

1. 采用两台带有虚拟机的电脑，虚拟机中操作系统 centos6，虚拟机中已装好oracle(也可以准备一台电脑装两个虚拟机)

• 两台电脑在同一个局域网下（可以同一个家用路由器下），使用桥接模式连通
• 两台虚拟机配置静态ip

2.一台电脑做主库，另一台做备库

1. 主库查询确认组数

$sqlplus /  as sysdba

select group#,thread#,members,status from v$log;

2. 增加standbylogfile

$sqlplus /  as sysdba

alter database add standby logfile  group 8 '/home/oracle/app/oracle/oradata/orcl/stdredo1.log' size 50m;
alter database add standby logfile  group 9 '/home/oracle/app/oracle/oradata/orcl/stdredo2.log' size 50m;
alter database add standby logfile  group 10 '/home/oracle/app/oracle/oradata/orcl/stdredo3.log' size 50m;
alter database add standby logfile  group 11 '/home/oracle/app/oracle/oradata/orcl/stdredo4.log' size 50m;

3. 在备库oracle用户创建归档目录，数据目录并设置权限oracle用户

mkdir -p /home/oracle/app/oracle/diag/orcl
mkdir -p /home/oracle/app/oracle/oradata/stdorcl/
mkdir -p /home/oracle/app/oracle/oradata/stdorcl/pdborcl
mkdir -p /home/oracle/arch
mkdir -p /home/oracle/rman
mkdir -p /home/oracle/app/oracle/oradata/stdorcl/pdbseed/
mkdir -p /home/oracle/app/oracle/oradata/stdorcl/pdb/

4. 主库环境开启强制归档

$sqlplus /  as sysdba

ALTER DATABASE FORCE LOGGING;

5. 在主库已开启归档模式下修改如下参数

$sqlplus /  as sysdba

alter system set LOG_ARCHIVE_CONFIG='DG_CONFIG=(orcl,stdorcl)' scope=both sid='*';         //sql>
alter system set log_archive_dest_1='LOCATION=/home/oracle/arch VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=orcl' scope=spfile;
alter system set LOG_ARCHIVE_DEST_2='SERVICE=stdorcl LGWR ASYNC  VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=stdorcl' scope=both sid='*';
alter system set fal_client='orcl' scope=both sid='*';    
alter system set FAL_SERVER='stdorcl' scope=both sid='*';  
alter system set standby_file_management=AUTO scope=both sid='*';
alter system set DB_FILE_NAME_CONVERT='/home/oracle/app/oracle/oradata/stdorcl/','/home/oracle/app/oracle/oradata/orcl/' scope=spfile sid='*';  
alter system set LOG_FILE_NAME_CONVERT='/home/oracle/app/oracle/oradata/stdorcl/','/home/oracle/app/oracle/oradata/orcl/' scope=spfile sid='*';
alter system set log_archive_format='%t_%s_%r.arc' scope=spfile sid='*';
alter system set remote_login_passwordfile='EXCLUSIVE' scope=spfile;
alter system set PARALLEL_EXECUTION_MESSAGE_SIZE=8192 scope=spfile;

6. 编辑主库以及备库的tnsnames.ora文件

#打开文件
$gedit /home/oracle/app/oracle/product/12.1.0/dbhome_1/network/admin/tnsnames.ora

加入一下内容：
ORCL =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.104)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)

stdorcl = (DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.103)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = orcl)
) )

7. 在主库上生成备库的参数文件

$sqlplus /  as sysdba

create pfile from spfile;

8. 将主库的参数文件，密码文件拷贝到备库

scp /home/oracle/app/oracle/product/12.1.0/dbhome_1/dbs/initorcl.ora 192.168.1.103:/home/oracle/app/oracle/product/12.1.0/dbhome_1/dbs/
scp /home/oracle/app/oracle/product/12.1.0/dbhome_1/dbs/orapworcl 192.168.1.103:/home/oracle/app/oracle/product/12.1.0/dbhome_1/dbs/

9. 在备库上更改参数文件

$gedit /home/oracle/app/oracle/product/12.1.0/dbhome_1/dbs/initorcl.ora

内容如下：
orcl.__data_transfer_cache_size=0
orcl.__db_cache_size=671088640

10. 在备库增加静态监听

$gedit /home/oracle/app/oracle/product/12.1.0/dbhome_1/network/admin/listener.ora

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME = /home/oracle/app/oracle/product/12.1.0/db_1)
(SID_NAME = orcl)
)
)

11. 主库进入rman模式

$rman target sys/123@orcl auxiliary sys/123@stdorcl

运行下面程序
run{
allocate channel c1 type disk;
allocate channel c2 type disk;
allocate channel c3 type disk;
allocate AUXILIARY channel c4 type disk;
allocate AUXILIARY channel c5 type disk;
allocate AUXILIARY channel c6 type disk;
DUPLICATE TARGET DATABASE
FOR STANDBY
FROM ACTIVE DATABASE
DORECOVER
NOFILENAMECHECK;
release channel c1;
release channel c2;
release channel c3;
release channel c4;
release channel c5;
release channel c6;
}

输出结果如下：
using target database control file instead of recovery catalog
allocated channel: c1
channel c1: SID=133 device type=DISK

allocated channel: c2 channel c2: SID=254 device type=DISK

allocated channel: c3 channel c3: SID=366 device type=DISK

allocated channel: c4 channel c4: SID=355 device type=DISK

allocated channel: c5 channel c5: SID=6 device type=DISK

allocated channel: c6 channel c6: SID=126 device type=DISK
