配置11Gr2 physical dataguard,11203 RAC 到single instance
11G DATA Guard在新特性physical standby可以在apply log时，open read only,并且可以real-time apply,这样standby db 也就告别了用户老觉的机器闲置，
丢掉了在发生故障时才见其价值的歧视。
standby db在高可用中不但可以用来做灾备，还可以平时用来测试、做报表统计，及logical standby的Rolling upgrade
下面配置一种DATA Guard,primary db是3nodes 11203 RAC,physical standby是11203 的single instance,Primary db有用到ASM存储文件，
Single instance只用local filesystem
primary database server:

下面正式开始DATA GUARD配置
1.physical standby安装oracle software . 另外创建db所需要的目录机构如adump,oradata,这里我们用OMF结构也就是ORACLE管理方式
[oracle@test188 ~]$ export ORACLE_SID=stdby
[oracle@test188 ~]$ echo $ORACLE_SID
stdby
[oracle@test188 ~]$ echo $ORACLE_BASE
/u01/app/oracle
[oracle@test188 ~]$ echo $ORACLE_HOME
/u01/app/oracle/product/11.2.0/dbhome_1
[oracle@test188 ~]$ mkdir -p $ORACLE_BASE/admin/$ORACLE_SID/{a,dp}dump
[oracle@test188 ~]$ mkdir -p $ORACLE_BASE/fast_recovery_area/$ORACLE_SID/onlinelog
[oracle@test188 ~]$ mkdir -p $ORACLE_BASE/oradata/$ORACLE_SID/datafile
[oracle@test188 ~]$ mkdir -p $ORACLE_BASE/oradata/$ORACLE_SID/tempfile
[oracle@test188 ~]$ mkdir -p $ORACLE_BASE/oradata/$ORACLE_SID/controlfile
[oracle@test188 ~]$ mkdir -p $ORACLE_BASE/oradata/$ORACLE_SID/onlinelog
2. 在standby db配置tnsnames.ora记录，这里我用的是SCAN 地址，也就是可以连接任何节点
ORCC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = scan-dgh)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcc)
)
)
3. 增加一个静态监听，在 physical standby db
[grid@test188 admin]$ cat listener.ora
# listener.ora Network Configuration File: /u01/app/11.2.0/grid/network/admin/listener.ora
# Generated by Oracle configuration tools.
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = stbydb)
(ORACLE_HOME = /u01/app/11.2.0/grid)
(SID_NAME = stbydb)
)
(SID_DESC =
(GLOBAL_DBNAME = stdby)
(ORACLE_HOME = /u01/app/11.2.0/grid)
(SID_NAME = stdby)
)
)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = test188)(PORT = 1521))
)
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
ADR_BASE_LISTENER = /u01/app/grid
ENABLE_GLOBAL_DYNAMIC_ENDPOINT_LISTENER = ON
lnsrctl reload
[grid@test188 admin]$ lsnrctl status

The command completed successfully
4. 在RAC的每个节点增加TNSNAMES.ORA记录,在primary db
[oracle@test183 admin]$ vi tnsnames.ora
[oracle@test183 admin]$ cat tnsnames.ora
# tnsnames.ora.test183 Network Configuration File: /u01/app/oracle/product/11.2.0/dbhome_1/network/admin/tnsnames.ora.test183
# Generated by Oracle configuration tools.
ORCC =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = scan-dgh)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = orcc)
)
)
STBYDB =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = test188)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = stbydb)
)
)
stdbytns =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = test188)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = stdby)
)
)
[oracle@test183 admin]$ scp tnsnames.ora test184:`pwd`
tnsnames.ora 100% 667 0.7KB/s 00:00
[oracle@test183 admin]$ scp tnsnames.ora test185:`pwd`
tnsnames.ora 100% 667 0.7KB/s 00:00
5. 启动force logging 在 primary DB
sys@RAC>select force_logging from v$database;
FOR
---
NO
sys@RAC>alter database force logging;
sys@RAC>select force_logging from v$database;
FOR
---
YES
6,对于网络认证我这里没有用SSL，而是PASSWORD文件,复制password文件从primary db到standby host's ORACLE_HOME/dbs,并重命名为standby instance
[oracle@test188 ~]$ export ORACLE_SID=stdby
[oracle@test188 ~]$ cd $ORACLE_HOME/dbs
[oracle@test188 dbs]$ ls -ltr
total 44
-rw-r--r-- 1 oracle oinstall 2851 May 15 2009 init.ora
-rw-r----- 1 oracle oinstall 4608 Oct 8 11:10 initorcc.ora.bak
-rw-rw---- 1 oracle oinstall 1544 Oct 8 11:21 hc_orcc.dat
-rw-r----- 1 oracle oinstall 24 Oct 8 11:24 lkORCC
-rw-rw---- 1 oracle oinstall 1544 Dec 11 09:12 hc_stbydb.dat
-rw-r--r-- 1 oracle oinstall 1515 Dec 11 09:53 initstbydb.ora
-rw-r----- 1 oracle asmadmin 24 Dec 11 10:33 lkSTBYDB

-rw-r----- 1 oracle asmadmin 4608 Dec 14 01:06 spfilestbydb.ora
[oracle@test188 dbs]$ cp orapwstbydb orapwstdby
7.修改 data guard 参数 to primary. 包括DG配置和 redo传输参数如SYNC,ASYNC, AFFIRM, NOAFFIRM, archive log ， datafile/logfile 文件名转换
SQL> show parameter log_archive_config
NAME TYPE VALUE
------------------------------------ ----------- ------------------------------
log_archive_config string dg_config=(orcc,stbydb)
SQL> alter system set log_archive_config='dg_config=(rac,stbydb,stdby)' scope=both ;
System altered.
SQL> show parameter log_archive_config

------------------------------------ ----------- ------------------------------
log_archive_config string dg_config=(rac,stbydb,stdby)
tip:

sys@RAC>alter system set log_archive_dest_1='location=use_db_recovery_file_dest valid_for=(all_logfiles,all_roles) db_unique_name=rac' scope=both;
System altered.
sys@RAC>alter system set log_archive_dest_4='service=STDBYTNS LGWR ASYNC NOAFFIRM max_failure=10 max_connections=5 reopen=180 valid_for=(online_logfiles,primary_role) db_unique_name=stdby' scope=both;

alter system set db_file_name_convert='+DATA1/stbydb','+DATA/orcc','/u01/app/oracle/oradata/stdby/','+DATA/orcc' scope=spfile;
alter system set log_file_name_convert='/u01/app/oracle/fast_recovery_area/stdby','+ARCH/orcc','/u01/app/oracle/fast_recovery_area/stdby','+DATA/orcc','+ARCH1/stbydb','+ARCH/orcc','+DATA1/stbydb','+DATA/orcc' scope=spfile;
sys@RAC>alter system set standby_file_management='AUTO' scope=both;
8,启用primary库rac 到archivelog mode
[oracle@znode1 oracle]$ srvctl stop database -d rac
[oracle@znode1 oracle]$ srvctl start database -d rac -o mount
idle>archive log list
Database log mode No Archive Mode
Automatic archival Disabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 72
Current log sequence 73
idle>alter database archivelog;
Database altered.
idle>archive log list
Database log mode Archive Mode
Automatic archival Enabled
Archive destination USE_DB_RECOVERY_FILE_DEST
Oldest online log sequence 72
Next log sequence to archive 73
Current log sequence 73
9,在standby database 创建初始化参数，只写db_name
[oracle@dbserver1 dbs]$ vi initstdby.ora
*.db_name='stdby'
10，standby database 启动到nomount状态
[oracle@dbserver1 dbs]$ sqlplus / as sysdba
SQL*Plus: Release 11.2.0.3.0 Production on Wed Aug 8 17:59:06 2012

11,用11g的新特性rman active duplicate 还原主库到备库，在primary host
[oracle@znode1 oracle]$ rman target / auxiliary sys/oracle@stdbytns
rman>
duplicate target database for standby from active database
spfile
set db_unique_name='stdby'
set db_file_name_convert='+DATA/orcc','/u01/app/oracle/oradata/stdby','+DATA/orcc/tempfile','/u01/app/oracle/oradata/stdby'
set log_file_name_convert='+ARCH/orcc','/u01/app/oracle/fast_recovery_area/stdby','+DATA/orcc','/u01/app/oracle/oradata/stdby'
set control_files='/u01/app/oracle/oradata/stdby/controlfile/control01.ctl'
set log_archive_max_processes='5'
set LOG_ARCHIVE_FORMAT='log%t_%s_%r.arc'
set REMOTE_LOGIN_PASSWORDFILE='EXCLUSIVE'
set fal_server='orcc'
SET cluster_database='false'
set db_create_file_dest = '/u01/app/oracle/oradata/stdby'
set db_recovery_file_dest = '/u01/app/oracle/fast_recovery_area'
set standby_file_management='AUTO'
set log_archive_config='dg_config=(orcc,stbydb,stdby)'
set log_archive_dest_2='service=PRIMARYTNS LGWR ASYNC NOAFFIRM max_failure=10 max_connections=5 reopen=180 valid_for=(online_logfiles,primary_role) db_unique_name=orcc'
set log_archive_dest_1='location=use_db_recovery_file_dest valid_for=(all_logfiles,all_roles) db_unique_name=stdby'
set audit_file_dest = '/u01/app/oracle/admin/stdby/adump'
set diagnostic_dest= '/u01/app/oracle'
reset REMOTE_LISTENER
reset local_listener;
TIP:
保证以下参数指定目录在备库存在audit_file_dest,control_files，如果没有audit_file_dest目录，备库会启动后无法登录遇ORA-09925 错误，解决方法是如下
[root@dbserver1 ~]# ps -ef|grep ora_|grep -v grep|awk '{print $2}'|xargs kill -9
[oracle@dbserver1 dbs]$ rm -rf /dev/shm/ora_stdby*
如果上面失败第二次duplicate会遇RMAN-05537，解决方法是shutdown abort standby db,rm spfile,startup nomount with pfile,re-run rman dumplicate on primary db
12,修改standby database spfile 记录，把primary instance记录删除，重建Standby spfile
sys@RAC>create pfile from spfile;
File created.

13,在standby db增加standby 日志 做real-time apply,standby log 每个thread 日志组比online log 组数多一个,standby日志大小与online redo相同
primary db:
sys@RAC>select group#,thread#,bytes,members from v$log;
GROUP# THREAD# BYTES MEMBERS
---------- ---------- ---------- ----------
1 1 52428800 2
2 1 52428800 2
3 2 52428800 2
4 2 52428800 2
standby db:
alter database add standby logfile size 52428800;
增加6组(number of group per thread +1)* number of thread
14,修改standby database 到archive log mode
15，Starting Redo Apply on the physical standby database
ALTER DATABASE RECOVER MANAGED STANDBY DATABASE USING CURRENT LOGFILE DISCONNECT;
USING CURRENT LOGFILE 表示接受到redo log立及应用，启用real-time apply
DISCONNECT 表示后台进程应用
有时因为primary db log_archive_dest_2 值 service=STDBYTNS LGWR ASYNC NOAFFIRM，不能保证适时传输时，需要alter system archive log current
或alter system switch logfile切日志查看
同步数据是否成功，当然也可以改log_archive_dest_2 的值。
验证日志传输与应用

The apply lag metric is computed using data that is periodically received from the primary database.
The DATUM_TIME column contains a timestamp of when this data was last
received by the standby database. The TIME_COMPUTED column contains a timestamp taken when the apply lag metric was calculated

当然可以建一张表来测试同步了,在两个节点上的事务也都可以同步到standby实例上
Stopping Redo Apply
