操作系统版本:IBM aix 6.2
数据库版本：11.2.0.4
软件运行架构：
主库为一个两节点的rac，备库也是一个两节点的rac，但备库只用于接收归档日志，不创建数据文件，不用于数据同步，用于接收来之主库的归档，以供ogg的日志挖取，并且准备在备库上架设一套ogg
ha环境；其中镜像用于存放归档的文件系统为ocfs文件系统；并且用于安装ogg软件；
简要操作步骤：
一、dg环境的搭建；
1、 强制归档：alter database force logging;
2、 创建备份的控制文件；
3、 更改主库初始化参数文件；
*.log_archive_config=‘DG_CONFIG=(shestate,racdg,archnw)‘
*.log_archive_dest_1=‘LOCATION=+ARCHVALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=shestate‘
*.log_archive_dest_2=‘SERVICE=racdgASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=racdg‘
*.log_archive_dest_3=‘SERVICE=archnw ARCH ASYNCVALID_FOR=(ALL_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=archnw‘
*.log_archive_dest_state_2=‘enable‘
*.log_archive_dest_state_3=‘enable‘
备库初始化参数文件内容：
*.audit_file_dest=‘/u01/app/oracle/admin/shestate/adump‘
*.audit_trail=‘db‘
*.cluster_database=true
*.compatible=‘11.2.0.4.0‘
*.control_files=‘/archnw/archlog/scontrol01.ctl‘,‘/archnw/archlog/scontrol02.ctl‘
*.db_block_size=8192
*.db_create_file_dest=‘/archnw/archlog/‘
*.db_domain=‘‘
*.db_name=‘shestate‘
*.db_unique_name=‘archnw‘
*.diagnostic_dest=‘/u01/app/oracle‘
*.dispatchers=‘(PROTOCOL=TCP)(SERVICE=racXDB)‘
archnw1.instance_number=1
archnw2.instance_number=2
*.log_archive_config=‘DG_CONFIG=(archnw,racdg,shestate)‘
*.log_archive_dest_1=‘LOCATION=/archnw/archlogVALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=archnw‘
*.log_archive_dest_2=‘SERVICE=racdgASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=racdg‘
*.log_archive_dest_3=‘SERVICE=shestate ARCH ASYNCVALID_FOR=(ALL_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=shestate‘
*.log_archive_dest_state_2=‘enable‘
*.log_archive_dest_state_3=‘enable‘
*.log_archive_format=‘%t_%s_%r.dbf‘
*.open_cursors=300
*.pga_aggregate_target=1284901888
*.processes=500
*.remote_listener=‘logrecv-cluster-scan:1521‘
*.remote_login_passwordfile=‘exclusive‘
*.sga_target=5654705664
archnw2.thread=2
archnw1.thread=1
archnw1.undo_tablespace=‘UNDOTBS1‘
archnw2.undo_tablespace=‘UNDOTBS2‘
4、 创建备库初始化参数文件中的aduit目录：（两节点均执行）
mkdir -p/u01/app/oracle/admin/shestate/adump
5、 更改两节点的oracle的配置文件.profile；
PATH=/usr/bin:/etc:/usr/sbin:/usr/ucb:$HOME/bin:/usr/bin/X11:/sbin:.
export PATH

6、 创建SPFILE;
$ sqlplus ‘/assysdba‘
SQL*Plus:Release 11.2.0.4.0 Production on Thu May 29 11:26:11 2014
Copyright (c)1982, 2013, Oracle. All rights reserved.
Connected to anidle instance.
SQL> createspfile=‘/archnw/archlog/spfilearchnw.ora‘ from pfile=‘/home/oracle/pfile.ora‘;
File created.
7、 恢复控制文件；
$ rman target /
RecoveryManager: Release 11.2.0.4.0 - Production on Thu May 29 11:29:32 2014
Copyright (c)1982, 2011, Oracle and/or its affiliates. All rights reserved.
connected totarget database: SHESTATE (not mounted)
RMAN> restorestandby controlfile from ‘/home/oracle/scontrol.ctl‘;

output filename=/archnw/archlog/scontrol01.ctl
output file name=/archnw/archlog/scontrol02.ctl
Finished restoreat 29-MAY-2014 11:30:19
8、 mount数据库；
$ sqlplus ‘/assysdba‘

----------------------------
archnw1 MOUNTED
SQL> selectname,open_mode,database_role from v$database;
NAME OPEN_MODE DATABASE_ROLE
----------------------------- ----------------
SHESTATE MOUNTED PHYSICAL STANDBY
9、 启动第二个节点的实例；
$ sqlplus ‘/assysdba‘
SQL*Plus:Release 11.2.0.4.0 Production on Thu May 29 11:32:56 2014
Copyright (c)1982, 2013, Oracle. All rights reserved.

10、 再次查看数据库实例状态；
SQL> selectinstance_name,status from gv$instance;
INSTANCE_NAME STATUS
----------------------------
archnw1 MOUNTED
archnw2 MOUNTED
SQL> selectname,open_mode,database_role from v$database;
NAME OPEN_MODE DATABASE_ROLE
----------------------------- ----------------
SHESTATE MOUNTED PHYSICAL STANDBY
11、 将数据库及其对应的实例加入到集群中；
srvctl adddatabase -d archnw -n shestate -r PHYSICAL_STANDBY -s MOUNT -o/u01/app/oracle/product/11.2.0/dbhome_1 -c RAC -p/archnw/archlog/spfilearchnw.ora -y AUTOMATIC
srvctl addinstance -d archnw -i archnw1 -n logrecv1
srvctl addinstance -d archnw -i archnw2 -n logrecv2
12、 查看添加的数据库及其实例资源状态；
$ crs_stat -t
Name Type Target State Host

13、 采用集群方式启动数据库；grid用户；
$ srvctl startdatabase -d archnw

14、 在内网主库的dns服务网两个节点的dns解析地址中增加日志档案库的解析地址；named.abc.data添加：
logrecv1 IN A 172.16.40.137
logrecv2 IN A 172.16.40.138
logrecv1-priv IN A 192.168.40.137
logrecv2-priv IN A 192.168.40.138
logrecv1-vip IN A 172.16.40.147
logrecv2-vip IN A 172.16.40.148
logrecv-cluster-scan IN A 172.16.40.149
logrecv-cluster-scan IN A 172.16.40.150
logrecv-cluster-scan IN A 172.16.40.151
在日志档案库的dns服务器的解析地址中增加内网集群的解析ip地址；
rac1 IN A 172.16.41.21
rac2 IN A 172.16.41.22
rac1-priv IN A 192.168.0.21
rac2-priv IN A 192.168.0.22
rac1-vip IN A 172.16.41.23
rac2-vip IN A 172.16.41.24
cluster1-scan IN A 172.16.41.121
cluster1-scan IN A 172.16.41.122
cluster1-scan IN A 172.16.41.123
15、 配置主库以及日志档案库上的tnsnames配置文件；
SHESTATE =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =cluster1-scan)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = shestate)
)
)
archnw =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST =logrecv-cluster-scan)(PORT = 1521))
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = archnw)
)
)
16、 拷贝主库的密码文件到日志档案库；
scp orapwrac1172.16.40.137:/u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwarchnw1
17、 在日志档案库里面创建standbylogfile;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 1 (‘/archnw/archlog/sredo1_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 1 (‘/archnw/archlog/sredo2_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 1 (‘/archnw/archlog/sredo3_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 1 (‘/archnw/archlog/sredo4_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 1 (‘/archnw/archlog/sredo5_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 1 (‘/archnw/archlog/sredo6_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 1 (‘/archnw/archlog/sredo7_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 2 (‘/archnw/archlog/sredo8_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 2 (‘/archnw/archlog/sredo9_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 2 (‘/archnw/archlog/sredo10_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 2 (‘/archnw/archlog/sredo11_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 2 (‘/archnw/archlog/sredo12_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 2 (‘/archnw/archlog/sredo13_01.log‘)SIZE 150M;
ALTER DATABASE ADD STANDBYLOGFILE THREAD 2 (‘/archnw/archlog/sredo14_01.log‘)SIZE 150M;
18、 由于镜像库还未启用，故暂时先将日志传输服务禁用；
Alter sysem setlog_archive_dest_state_2=’defer’ scope=both sid=’*’;
