1、rac主库开启归档
[oracle@rac1:/home/oracle]$sqlplus / as sysdba
SQL> startup mount;
SQL> alter system set log_archive_dest_1='location=+arch' scope=spfile;
System altered.
SQL> alter database archivelog;
Database altered.
SQL> alter database force logging;
Database altered.
开启数据库
SQL> alter database open;
2、修改主库适应dataguard环境参数
当主库已开启force logging之后再进行如下操作
alter database force logging;
alter system set LOG_ARCHIVE_CONFIG='DG_CONFIG=(orcl,std)' scope=both sid='*';
alter system set log_archive_dest_1='LOCATION=+arch VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=orcl' scope=spfile;
alter system set LOG_ARCHIVE_DEST_2='SERVICE=std LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=std' scope=both sid='*';
alter system set fal_client='orcl' scope=both sid='*';
alter system set FAL_SERVER='std' scope=both sid='*';
alter system set standby_file_management=AUTO scope=both sid='*';
alter system set DB_FILE_NAME_CONVERT='/u01/app/oracle/oradata/orcl/datafile','+DATA/orcl/datafile','/u01/app/oracle/oradata/orcl/tempfile','+DATA/orcl/tempfile' scope=spfile sid='*';
alter system set LOG_FILE_NAME_CONVERT='/u01/app/oracle/oradata/orcl/onlinelog','+DATA/orcl/onlinelog' scope=spfile sid='*';
alter system set log_archive_format='%t_%s_%r.arc' scope=spfile sid='*';
alter system set remote_login_passwordfile='EXCLUSIVE' scope=spfile;
alter system set PARALLEL_EXECUTION_MESSAGE_SIZE=8192 scope=spfile;
重启数据库
3、主库增加srl日志组
SQL> select bytes/1024/1024 mb from v$log;
MB
----------
300
300
300
300
主库增加standby日志组：
主库时2组logfile，slr需要至少多一组，每个thread多一组
alter database add standby logfile thread 1 group 5 '+data' size 200m;
alter database add standby logfile thread 1 group 6 '+data' size 200m;
alter database add standby logfile thread 1 group 7 '+data' size 200m;
alter database add standby logfile thread 2 group 8 '+data' size 200m;
alter database add standby logfile thread 2 group 9 '+data' size 200m;
alter database add standby logfile thread 2 group 10 '+data' size 200m;
4、主库备库增加tns别名
主库tnsnamrs:
orcl =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac-scan)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
)
)
std =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = std)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = std)
)
)
备库tnsnames：
orcl =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac-scan)(PORT = 1521))
(LOAD_BALANCE = yes)
(FAILOVER = yes)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcl)
(FAILOVER_MODE =
(TYPE = SELECT)
(METHOD = BASIC)
(RETRIES = 180)
(DELAY = 5)
)
)
)
std =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = std)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = std)
)
)
5、拷贝主库密码文件到备库
ASMCMD> pwd
+data/orcl/password
ASMCMD> cp pwdorcl.256.998919277 /tmp/orapwstd
copying +data/orcl/password/pwdorcl.256.998919277 -> /tmp/orapwstd
将/tmp目录的密码文件拷贝到备库dbs目录
对参数文件，密码文件重命名符合备库实例命名规范
[oracle@std:/u01/app/oracle/product/18.3.0/db_1/dbs]$mv orapworcl1 orapwstd
[oracle@std:/u01/app/oracle/product/18.3.0/db_1/dbs]$mv orcl.ora initstd.ora
6、备库创建实例目录
mkdir -p /u01/arch
mkdir -p /u01/app/oracle/oradata/std
mkdir -p /u01/app/oracle/oradata/std/datafile/
mkdir -p /u01/app/oracle/oradata/std/tempfile/
mkdir -p /u01/app/oracle/admin/std/adump/
mkdir -p /u01/app/oracle/oradata/std/onlinelog/
7、修改备库实例pfile文件
[oracle@std:/u01/app/oracle/product/18.3.0/db_1/dbs]$vi initstd.ora
*.audit_file_dest='/u01/app/oracle/admin/std/adump'
*.audit_trail='NONE'
*.compatible='19.0.0'
*.control_files='/u01/app/oracle/oradata/std/control01.ctl','/u01/app/oracle/oradata/std/control02.ctl'
*.db_block_size=8192
*.db_domain=''
*.db_name='orcl'
*.db_unique_name='std'
*.diagnostic_dest='/u01/app/oracle'
*.log_archive_format='%t_%s_%r.arc'
*.open_cursors=300
*.pga_aggregate_target=1g
*.processes=1000
*.remote_login_passwordfile='exclusive'
*.sga_target=6g
*.LOG_ARCHIVE_CONFIG='DG_CONFIG=(std,orcl)'
*.LOG_ARCHIVE_DEST_1='LOCATION=/u01/arch VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=std'
*.LOG_ARCHIVE_DEST_2='SERVICE=orcl LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=orcl'
*.log_archive_format='%t_%s_%r.arc'
*.FAL_SERVER='orcl'
*.fal_client='std'
*.FAL_SERVER='orcl'
*.DB_FILE_NAME_CONVERT='+DATA/ORCL/DATAFILE/','/u01/app/oracle/oradata/std/datafile/','+DATA/orcl/tempfile/','/u01/app/oracle/oradata/std/tempfile/'
*.LOG_FILE_NAME_CONVERT='+DATA/ORCL/ONLINELOG/','/u01/app/oracle/oradata/std/onlinelog/'
*.standby_file_management=AUTO
8、增加备库静态监听
[oracle@std:/u01/app/oracle/product/18.3.0/db_1/network/admin]$vi listener.ora
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(ORACLE_HOME = /u01/app/oracle/product/18.3.0/db_1)
(SID_NAME = std)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = std)(PORT = 1521))
)
)
lsnrctl start
9、启动备库
export ORACLE_SID=std
SQL> startup nomount;
10、主库准备连接辅助实例
[oracle@rac1 ~]$ rman target sys/oracle@orcl auxiliary sys/oracle@std
Recovery Manager: Release 19.0.0.0.0 - Production on Mon Jul 22 09:45:32 2019

11、开始备库创建
执行脚本
