环境描述：
Version:11.2.0.3.0
Primary端：
双节点的RAC,scan使用DNS解析,跑两个实例(JSTDB&PAYDB)
Standby端：
单机的Dataguard
1.设置网络环境;
vi /etc/hosts
192.168.253.101 rac1.test.com rac1
192.168.253.102 rac2.test.com rac2
192.168.253.103 rac1-vip.test.com rac1-vip
192.168.253.104 rac2-vip.test.com rac2-vip
10.10.10.11 rac1-priv.test.com rac1-priv
10.10.10.12 rac2-priv.test.com rac2-priv
192.168.253.200 standby
vi /etc/resolv.conf
nameserver 192.168.253.100
nslookup scan.test.com
Server:192.168.253.100
Address:192.168.253.100#53
Name:scan.test.com
Address: 192.168.253.107
Name:scan.test.com
Address: 192.168.253.106
Name:scan.test.com
Address: 192.168.253.105

3.查看并添加standby logfile;
set line 180 pages 1000
col member for a50
select * from v$logfile order by GROUP#;
alter system set standby_file_management=manual scope=both sid='*';
alter database add standby logfile thread 1 group 5 '+DATA/jstdb/onlinelog/standby_redo1-1.log' size 50M;
alter database add standby logfile thread 1 group 6 '+DATA/jstdb/onlinelog/standby_redo1-2.log' size 50M;
alter database add standby logfile thread 1 group 7 '+DATA/jstdb/onlinelog/standby_redo1-3.log' size 50M;
alter database add standby logfile thread 1 group 8 '+DATA/jstdb/onlinelog/standby_redo1-4.log' size 50M;
alter database add standby logfile thread 2 group 9 '+DATA/jstdb/onlinelog/standby_redo2-1.log' size 50M;
alter database add standby logfile thread 2 group 10 '+DATA/jstdb/onlinelog/standby_redo2-2.log' size 50M;
alter database add standby logfile thread 2 group 11 '+DATA/jstdb/onlinelog/standby_redo2-3.log' size 50M;
alter database add standby logfile thread 2 group 12 '+DATA/jstdb/onlinelog/standby_redo2-4.log' size 50M;
alter system set standby_file_management=auto scope=both sid='*';
4.收集主库的相关信息;
set line 180 pages 1000
col value for a90
col name for a50
select name,value from v$parameter
where name in ('db_name',
'db_unique_name',
'log_archive_config',
'log_archive_dest_1',
'log_archive_dest_2',
'log_archive_dest_state_1',
'log_archive_dest_state_2',
'remote_login_passwordfile',
'remote_listener',
'log_archive_format',
'log_archive_max_processes',
'fal_server','fal_client',
'db_file_name_convert',
'log_file_name_convert',
'standby_file_management');
5.创建本地硬盘的归档日志目录以及rman的备份目录;
mkdir -p /u01/arch/JSTDB
chown -R oracle.oinstall /u01/arch/
mkdir -p /u01/rman/JSTDB
chown -R oracle.oinstall /u01/rman/
6.修改主库的DG配置;
ALTER SYSTEM SET DB_UNIQUE_NAME=JSTDB scope=both sid='*';
ALTER SYSTEM SET LOG_ARCHIVE_CONFIG='DG_CONFIG=(JSTDB,JSTDG1)' scope=both sid='*';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_1='LOCATION=+FRA/JSTDB/ARCHIVELOG/ VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=JSTDB' scope=both sid='*';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_2='SERVICE=JSTDG1 LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=JSTDG1' scope=both sid='*';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_1=ENABLE scope=both sid='*';
ALTER SYSTEM SET LOG_ARCHIVE_DEST_STATE_2=ENABLE scope=both sid='*';
ALTER SYSTEM SET REMOTE_LOGIN_PASSWORDFILE=SHARED scope=spfile sid='*';
ALTER SYSTEM SET REMOTE_LISTENER='scan.test.com:1521' scope=spfile sid='*';
ALTER SYSTEM SET LOG_ARCHIVE_MAX_PROCESSES=8 SCOPE=both sid='*';
ALTER SYSTEM SET FAL_CLIENT=JSTDB SCOPE=both sid='*';
ALTER SYSTEM SET FAL_SERVER=JSTDG1 SCOPE=both sid='*';
ALTER SYSTEM SET db_file_name_convert='/u01/app/oracle/oradata/JSTDG1/','+DATA/JSTDB/' SCOPE=spfile sid='*';
ALTER SYSTEM SET log_file_name_convert='/u01/app/oracle/oradata/JSTDG1/onlinelog/','+DATA/JSTDB/onlinelog/','/u01/app/oracle/oradata/JSTDG1/onlinelog/','+FRA/JSTDB/onlinelog/','/u01/arch/JSTDG1/','+FRA/JSTDB/ARCHIVELOG/' SCOPE=spfile sid='*';
ALTER SYSTEM SET STANDBY_FILE_MANAGEMENT=AUTO SCOPE=both sid='*';
修改archivelog的格式
alter system set log_archive_format='arch_%r_%t_%s.arc' scope=spfile sid='*';
shutdown immediate
startup
7.创建standby数据库的pfile文件;
create pfile='/u01/rman/initJSTDB.ora' from spfile;
8.修改tns;
cd $ORACLE_HOME/network/admin
vi tnsnames.ora
# tnsnames.ora Network Configuration File: /u01/app/oracle/product/11.2.0/db_1/network/admin/tnsnames.ora
# Generated by Oracle configuration tools.
JSTDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = scan.test.com)(PORT = 1521))
(LOAD_BALANCE = yes)
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = JSTDB)
)
)
JSTDB1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1.test.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = rac1-vip.test.com)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = JSTDB)
(INSTANCE_NAME = JSTDB1)
)
)
JSTDB2 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = rac2.test.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = TCP)(HOST = rac2-vip.test.com)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = JSTDB)
(INSTANCE_NAME = JSTDB2)
)
)
JSTDG1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = standby)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = JSTDG1)
)
)
PAYDB =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = scan.test.com)(PORT = 1521))
(LOAD_BALANCE = yes)
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PAYDB)
)
)
PAYDG1 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = standby)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = PAYDB)
)
)
9.备库添加监听;
cd $ORACLE_HOME/network/admin
vi listener.ora
# listener.ora Network Configuration File: /u01/app/oracle/network/admin/listener.ora
# Generated by Oracle configuration tools.
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = standby)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = JSTDG1)
(ORACLE_HOME = /u01/app/oracle)
(SID_NAME = JSTDB)
)
(SID_DESC =
(GLOBAL_DBNAME = PAYDG1)
(ORACLE_HOME = /u01/app/oracle)
(SID_NAME = PAYDB)
)
)
ADR_BASE_LISTENER = /u01/app/oracle
备库重启监听服务
lsnrctl stop
lsnrctl start
10.在RAC节点1生成standby控制文件;
export ORACLE_SID=JSTDB1
rman target /
backup device type disk format '/u01/rman/ctl01.ctl' current controlfile for standby;
scp /u01/rman/ctl01.ctl standby:/u01/rman/
11.在standby创建相关目录;
@root用户
mkdir -p /u01/rman/JSTDB
chown -R oracle.oinstall /u01/rman/
mkdir -p /u01/arch/JSTDG1
chown -R oracle.oinstall /u01/arch/
@oracle用户
mkdir -p /u01/app/oracle/oradata/JSTDG1/datafile/
mkdir -p /u01/app/oracle/oradata/JSTDG1/onlinelog
mkdir -p /u01/app/oracle/admin/JSTDG1/adump
12.复制密码文件;
orapwd file=/$ORACLE_HOME/dbs/orapwJSTDB1 password=oracle force=y ignorecase=y
scp /$ORACLE_HOME/dbs/orapwJSTDB1 rac2:/$ORACLE_HOME/dbs/orapwJSTDB2
scp /$ORACLE_HOME/dbs/orapwJSTDB1 standby:/u01/app/oracle/dbs/orapwJSTDB
13.拷贝参数文件到备库，并修改相关内容;
@主库
scp /u01/rman/initJSTDB.ora standby:/u01/app/oracle/dbs/initJSTDB.ora
@备库
vi /u01/app/oracle/dbs/initJSTDB.ora
*.audit_file_dest='/u01/app/oracle/admin/JSTDG1/adump'
*.audit_trail='db'
*.compatible='11.2.0.0.0'
*.control_files='/u01/app/oracle/oradata/JSTDG1/control01.ctl','/u01/app/oracle/oradata/JSTDG1/control02.ctl','/u01/app/oracle/oradata/JSTDG1/control03.ctl'
*.db_block_size=8192
#*.db_create_file_dest='/u01/app/oracle/oradata/'
#*.db_create_online_log_dest_1='/u01/app/oracle/oradata/onlinelog/'
*.db_domain=''
*.db_file_name_convert='+DATA/JSTDB/','/u01/app/oracle/oradata/JSTDG1/'
*.db_name='JSTDB'
*.db_unique_name='JSTDG1'
*.db_recovery_file_dest=''
*.fal_client='JSTDG1'
*.fal_server='JSTDB'
*.log_archive_config='DG_CONFIG=(JSTDB,JSTDG1)'
*.log_archive_dest_1='LOCATION=/u01/arch/JSTDG1/ VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=JSTDG1'
*.log_archive_dest_2='SERVICE=JSTDB LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=JSTDB'
*.log_archive_format='arch_%r_%t_%s.arc'
*.log_archive_dest_state_1='ENABLE'
*.log_archive_dest_state_2='ENABLE'
*.log_archive_max_processes=8
*.log_file_name_convert='+DATA/JSTDB/onlinelog/','/u01/app/oracle/oradata/JSTDG1/onlinelog/','+FRA/JSTDB/onlinelog/','/u01/app/oracle/oradata/JSTDG1/onlinelog/','+FRA/JSTDB/ARCHIVELOG/','/u01/arch/JSTDG1/'
*.open_cursors=300
*.processes=150
*.remote_login_passwordfile='SHARED'
*.standby_file_management='AUTO'
*.undo_management='AUTO'
undo_tablespace='UNDOTBS1'
14.把备库启动到nomount状态;
export ORACLE_SID=JSTDB
sqlplus / as sysdba
startup nomount pfile='/u01/app/oracle/dbs/initJSTDB.ora';
create spfile from pfile='/u01/app/oracle/dbs/initJSTDB.ora';
15.恢复备库的控制文件;
rman target /
restore standby controlfile from '/u01/rman/ctl01.ctl';
16.收集RAC数据库的信息;
col file_name for a70
select file_name, file_id from dba_data_files;
FILE_NAME FILE_ID
---------------------------------------------------------------------- ----------
+DATA/jstdb/datafile/system.259.9079385031
+DATA/jstdb/datafile/sysaux.260.9079385092
+DATA/jstdb/datafile/undotbs1.261.9079385153
+DATA/jstdb/datafile/undotbs2.263.9079385254
+DATA/jstdb/datafile/users.264.9079385275
4 rows selected.
17.备份主库全库（仅供保险备份，不是拷贝到standby）;
rman target /
backup format '/u01/rman/JSTDB/fulldb_%d_%U' database include current controlfile plus archivelog delete input;
