1. 配置主库允许强制记日志
SQL> alter  database force logging;

SQL> SELECT FORCE_LOGGING FROM V$DATABASE;

FOR
---
YES


2. 把主库的密码文件复制到备库并修改所属用户为ORACLE所属组为OINSTALL
$cd  $ORACLE_HOME/dbs
$ scp -P 17698 orcl1 root@192.168.1.13:/home/oracle/app/oracle/product/11.2.0/dbhome_1/dbs/orcl_dg
--在备库操作
[root@fsdb02 tmp]# chown oracle.oinstall /home/oracle/app/oracle/product/11.2.0/dbhome_1/dbs/orcl_dg


3. 主库配置DG参数

--修改主库初始化参数

SQL>
alter system set log_archive_config='DG_CONFIG=(orcl,orcl_dg)' scope=both;
alter system set log_archive_dest_1='location=+ARCH valid_for=(all_logfiles,all_roles) db_unique_name=orcl' scope=both;
alter system set log_archive_dest_2='SERVICE=orcl_dg LGWR ASYNC valid_for=(online_logfiles,primary_role) COMPRESSION=ENABLE db_unique_name=orcl_dg' scope=both;

--设置主库备角色参数
SQL>
alter system set FAL_SERVER=orcl_dg scope=both;
alter system set FAL_CLIENT=orcl  scope=both;
alter system set DB_FILE_NAME_CONVERT='orcl','orcl_dg' scope=spfile;
alter system set LOG_FILE_NAME_CONVERT='/data/orclarch/','+ARCH' scope=spfile;
alter system set standby_file_management=AUTO scope=both;

4. 在主库创建 PFILE，然后把PFILE复制到备库修改参数作为备库的参数文件

SQL> CREATE pfile='/tmp/orcl.ora' from spfile;

scp -P 17698  /tmp/orcl.ora root@192.168.1.13:/tmp

--在备库修改PFILE
*.audit_file_dest='/home/oracle/app/oracle/admin/orcl/adump'
*.audit_trail='db'
*.compatible='11.2.0.4.0'
*.control_files='/data/oradata/orcl/control01.ctl','/data/oradata/orcl/control02.ctl'
*.db_block_size=8192
*.db_domain=''
*.db_name='orcl'
*.db_unique_name='orcl_dg'
*.diagnostic_dest='/home/oracle/app/oracle'
*.dispatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)'
*.job_queue_processes=1000
*.log_archive_dest_1='location=/data/orclarch'
*.open_cursors=500
*.open_links=100
*.pga_aggregate_target=4724464025
*.processes=2000
*.sessions=2205
*.sga_target=18897856102
*.undo_tablespace='UNDOTBS1'

备库创建相关目录
--创建存放数据文件的目录
su - oracle
$mkdir -p /data/oradata/orcl
--创建audit_file_dest 目录
su - oracle
$ mkdir /home/oracle/app/oracle/admin/orcl/adump -p
--创建归档日志目录
mkdir /data/orclarch



创建备控制文件
SQL> ALTER DATABASE CREATE STANDBY CONTROLFILE AS '/tmp/orcl.ctl';

scp  -P 17698 /tmp/orcl.ctl root@192.168.1.13:/tmp

在备库复制控制文件到指定的位置
#cp /tmp/orcl.ctl /data/oradata/orcl/control01.ctl
#cp /tmp/orcl.ctl /data/oradata/orcl/control02.ctl
# chown -R oracle.oinstall /data/oradata/orcl


使用PFIEL启动数据库实例，创建SPFILE
export ORACLE_SID=orcl_dg
SQL> startup mount pfile='/tmp/orcl.ora';
SQL> create spfile from pfile='/tmp/orcl.ora';
SQL> shutdown immediate;
SQL> startup mount;

修改备库DG参数
alter system set log_archive_config='DG_CONFIG=(orcl,orcl_dg)' scope=both;
alter system set DB_FILE_NAME_CONVERT='orcl','orcl_dg' scope=spfile;
alter system set LOG_FILE_NAME_CONVERT='/data/orclarch/','+ARCH' scope=spfile;


alter  system set log_archive_dest_1='location=/data/orclarch valid_for=(all_logfiles,all_roles) db_unique_name=orcl_dg' scope=both;
alter system set log_archive_dest_2='SERVICE=orcl LGWR ASYNC valid_for=(online_logfiles,primary_role) COMPRESSION=ENABLE db_unique_name=orcl' scope=both;



alter system set FAL_SERVER=orcl scope=both;
alter system set FAL_CLIENT=orcl_dg  scope=both;
alter system set standby_file_management=AUTO scope=both;

把前一天的RMAN备份复制到备库 /home/oracle/lom 目录下,并设置备份文件的所属用户为
oracle所属组为 oinstall

删除控制文件中原来的备份信息，注册新的备份信息

RMAN> crosscheck backup;
RMAN> crosscheck archivelog all;
RMAN> delete noprompt expired backup;
RMAN> delete noprompt expired archivelog all;
RMAN> delete backup;
RMAN>delete expired backup of archivelog all;


RMAN> catalog start with '/home/oracle/olm';
---注意此次不能使用 catalog start with '/home/oracle/olm/'，后面多了个斜线会导致无法找到文件


--生成RMAN数据文件交换语句的SQL
