一，准备
 
Database DB_UNIQUE_NAME Oracle Net Service Name
Primary PROD PROD
Physical standby PRODDG PRODDG
 
二，主库设置
 
1.启用force logging
alter database force logging;
2.确认主库处于归档模式
archive log list;
3.在primary库创建standby数据库控制文件
alter database create standby controlfile as '/dsg/oracle11/back/prordg.ctl';
4.创建primary库客户端初始化参数文件
1).创建主库中的pfile
create pfile from spfile;
2).备份到backup目录用于创建备库的pfile
cp $ORACLE_HOME/dbs/initPROD.ora $ORACLE_HOME/dbs/initPRODDG.ora

3).修改后主库pfile中内容如下：

*.db_domain=''

*.db_name='PROD'

*.diagnostic_dest='/u01/app/oracle'

*.dispatchers='(PROTOCOL=TCP) (SERVICE=PRODXDB)'

*.open_cursors=

*.pga_aggregate_target=

*.processes=

*.remote_login_passwordfile='EXCLUSIVE'

*.sga_target=

*.undo_tablespace='UNDOTBS1'

#################################################################

#Parameters for Primary Database.

#################################################################

*.DB_NAME='PROD'

*.DB_UNIQUE_NAME=PROD

*.LOG_ARCHIVE_FORMAT=log%t_%s_%r.arc

*.LOG_ARCHIVE_CONFIG='DG_CONFIG=(PROD,PRODDG)'

*.LOG_ARCHIVE_DEST_1='LOCATION=/dsg/oracle11/PROD/arch VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=PROD'

*.LOG_ARCHIVE_DEST_2='SERVICE=PRODDG LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=PRODDG'

*.LOG_ARCHIVE_DEST_STATE_1=ENABLE

*.LOG_ARCHIVE_DEST_STATE_2=ENABLE

*.REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE

#################################################################

#Parameters which using for switch over from Primary to Standby.

#################################################################

*.FAL_SERVER=PRODDG

*.FAL_CLIENT=PROD

*.DB_FILE_NAME_CONVERT='/dsg/oracle11/PRODDG','/dsg/oracle11/PROD'

*.LOG_FILE_NAME_CONVERT='/dsg/oracle11/PRODDG','/dsg/oracle11/PROD'

*.STANDBY_FILE_MANAGEMENT=AUTO
4）通过pfile创建spfile
SQL> shutdown immediate

Database closed.

Database dismounted.

ORACLE instance shut down.

SQL> create spfile from pfile;

File created.
4.配置tnsnames.ora文件和listener.ora 文件（由于是一个服务器上的两个数据库，所以standby数据库不需要再配置）
 
如果在不同的服务器上那么两个服务器上都要配置
 cat listener.ora 

LISTENER =

(ADDRESS_LIST=

      (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.70)(PORT=))

      (ADDRESS=(PROTOCOL=ipc)(KEY=PNPKEY)))

SID_LIST_LISTENER=

  (SID_LIST=

      (SID_DESC=

         (GLOBAL_DBNAME=db11)

         (SERVICE_NAME = DB11)

         (SID_NAME=db111)

         (ORACLE_HOME=/u01/app/oracle/product/11.2.)

        (PRESPAWN_MAX=)

        (PRESPAWN_LIST=

          (PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=)(TIMEOUT=))

        )

       )

      (SID_DESC=

         (GLOBAL_DBNAME=PROD)

         (SERVICE_NAME = PROD)

         (SID_NAME=PROD)

         (ORACLE_HOME=/u01/app/oracle/product/11.2.)

        (PRESPAWN_MAX=)

        (PRESPAWN_LIST=

          (PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=)(TIMEOUT=))

        )

       )

      (SID_DESC=

         (GLOBAL_DBNAME=PRODDG)

         (SERVICE_NAME = PRODDG)

         (SID_NAME=PRODDG)

         (ORACLE_HOME=/u01/app/oracle/product/11.2.)

        (PRESPAWN_MAX=)

        (PRESPAWN_LIST=

          (PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=)(TIMEOUT=))

        )

       )

)

cd $ORACLE_HOME/network/admin

PROD =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.70)(PORT = ))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = PROD)

    )

  )

PRODDG =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.70)(PORT = ))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = PRODDG)

    )

  )

EXTPROC_CONNECTION_DATA =

  (DESCRIPTION =

    (ADDRESS_LIST =

      (ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC0))

    )

    (CONNECT_DATA =

      (SID = PLSExtProc)

      (PRESENTATION = RO)

    )

  )

PROD@dbrac1  /u01/app/oracle/product/11.2./network/admin$ tnsping prod

OK ( msec)
三，Standby 数据库配置设置
 
 
1.创建密码文件，注意sys的密码和主库的密码一致（说明：这里不要这样创建standby的密码文件） 报错信息见最后
cd $ORACLE_HOME/dbs

orapwd file=orapwPRODDG force=y password=oracle entries=
推荐直接拷贝primary数据的密码文件：
cd $ORACLE_HOME/dbs

cp  orapwPROD  orapwPROD
2.创建standby所需的目录（注意11g和10g有所区别）
cd $ORACLE_BASE/admin

mkdir -p PRODDG/adump

mkdir -p PRODDG/dpdump
创建Standby的数据文件及日志文件，控制文件所在目录
mkdir  /dsg/oracle11/PRODDG
3，拷贝主库生成的standby控制文件和主库的数据文件，日志文件
cp /dsg/oracle11/back/prordg.ctl  /dsg/oracle11/PRODDG/

cp  prordg.ctl control01.ctl

cp control01.ctl  control02.ctl
4，修改standby参数文件
 
1）修改参数如下：
cat initPRODDG.ora

PRODDG.__db_cache_size=

PRODDG.__java_pool_size=

PRODDG.__large_pool_size=

PRODDG.__oracle_base='/u01/app/oracle'#ORACLE_BASE set from environment

PRODDG.__pga_aggregate_target=

PRODDG.__sga_target=

PRODDG.__shared_io_pool_size=

PRODDG.__shared_pool_size=

PRODDG.__streams_pool_size=

*.audit_file_dest='/u01/app/oracle/admin/PRODDG/adump'

*.audit_trail='db'

*.compatible='11.2.0.0.0'

*.control_files='/dsg/oracle11/PRODDG/control01.ctl','/dsg/oracle11/PRODDG/control02.ctl'

*.db_block_size=

*.db_domain=''

*.db_name='PROD'    ##注意和主库的一致

*.diagnostic_dest='/u01/app/oracle'

*.dispatchers='(PROTOCOL=TCP) (SERVICE=PRODDGXDB)'

*.open_cursors=

*.pga_aggregate_target=

*.processes=

*.remote_login_passwordfile='EXCLUSIVE'

*.sga_target=

*.undo_tablespace='UNDOTBS1'

#################################################################

#Parameters for Standby Database.

#################################################################

*.DB_UNIQUE_NAME=PRODDG

*.LOG_ARCHIVE_FORMAT=log%t_%s_%r.arc

*.LOG_ARCHIVE_CONFIG='DG_CONFIG=(PROD,PRODDG)'

*.DB_FILE_NAME_CONVERT='/dsg/oracle11/PROD','/dsg/oracle11/PRODDG'

*.LOG_FILE_NAME_CONVERT='/dsg/oracle11/PROD','/dsg/oracle11/PRODDG'

*.FAL_SERVER=PROD

*.FAL_CLIENT=PRODDG

*.STANDBY_FILE_MANAGEMENT=AUTO

#################################################################

#Parameters which using for switch over from Standby to Primary.

#################################################################

*.LOG_ARCHIVE_DEST_1='LOCATION=/dsg/oracle11/PRODDG/arch VALID_FOR=(ALL_LOGFILES,ALL_ROLES) DB_UNIQUE_NAME=PRODDG'

*.LOG_ARCHIVE_DEST_2='SERVICE=PROD LGWR ASYNC VALID_FOR=(ONLINE_LOGFILES,PRIMARY_ROLE) DB_UNIQUE_NAME=PROD'

*.LOG_ARCHIVE_DEST_STATE_1=ENABLE

*.LOG_ARCHIVE_DEST_STATE_2=ENABLE

*.REMOTE_LOGIN_PASSWORDFILE=EXCLUSIVE
2）生成spfile
PROD@dbrac1  /home/oracle$ export ORACLE_SID=PRODDG

PRODDG@dbrac1  /home/oracle$ sql

SQL*Plus: Release 11.2.0.1. Production on Thu Apr  :: 

Copyright (c) , , Oracle.  All rights reserved.

Connected to an idle instance.

SQL> create spfile from pfile;

File created.
5.启动Standby到mount
SQL> startup mount

6，启动redo应用
alter database recover managed standby database disconnect from session;
7，查看同步情况
 
连到主库
SQL> set line

SQL> select instance_name,host_name,version,status from v$instance;

INSTANCE_NAME    HOST_NAME                                                        VERSION           STATUS

---------------- ---------------------------------------------------------------- ----------------- ------------

PROD                            dbrac1                                                           11.2.0.1.        OPEN

SQL> alter system switch logfile;

System altered.

SQL> select max(sequence#) from v$archived_log;

MAX(SEQUENCE#)

--------------
连接到standby数据库
SQL> select max(sequence#) from v$archived_log;

MAX(SEQUENCE#)

--------------

，取消日志应用

ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;
四，验证
 
在主库创建一个用户，并且创建一张表
SQL> create user hxy identified by hxy;

User created.

SQL> grant dba to hxy;

Grant succeeded.

SQL> conn hxy/hxy

Connected.

SQL> create table t as select * from dba_users;

Table created.

SQL> alter system switch logfile;

System altered.

SQL> select max(sequence#) from v$archived_log;

MAX(SEQUENCE#)

--------------
去备库验证 一番
 
连接standby数据库
SQL> select max(sequence#) from v$archived_log;

MAX(SEQUENCE#)

--------------

SQL> ALTER DATABASE RECOVER MANAGED STANDBY DATABASE CANCEL;

Database altered.

SQL> alter database open read only;

Database altered.

SQL> conn hxy/hxy

Connected.

SQL> select * from tab;

TNAME                          TABTYPE  CLUSTERID

------------------------------ ------- ----------

T                              TABLE

SQL> select count(*) from t;

  COUNT(*)

----------
OK，没有问题！
 
五，主备切换
 
1，连接到primary数据库，切换操作
SQL> conn / as sysdba

Connected.

SQL> select switchover_status from v$database;

SWITCHOVER_STATUS

--------------------

TO STANDBY

SQL>  alter database commit to switchover to physical standby with session shutdown;

Database altered.

SQL> shutdown immediate

ORA-: database not mounted

ORACLE instance shut down.

SQL>  startup nomount

ORACLE instance started.

Total System Global Area   bytes

Fixed Size                   bytes

Variable Size              bytes

Database Buffers           bytes

Redo Buffers                 bytes

SQL>  alter database mount standby database;

Database altered.

SQL> select database_role from v$database;

DATABASE_ROLE

----------------

PHYSICAL STANDBY

SQL> alter database recover managed standby database disconnect from session parallel ;

Database altered.
2，连接到standby数据库

SQL> select switchover_status from v$database;

SWITCHOVER_STATUS

--------------------

TO PRIMARY

SQL>  alter database commit to switchover to primary with session shutdown ;

Database altered.

SQL> shutdown immediate

ORA-: database not open

Database dismounted.

ORACLE instance shut down.

SQL> startup

Redo Buffers                 bytes

Database mounted.

Database opened.

SQL> select database_role from v$database;

DATABASE_ROLE

----------------

PRIMARY
Ok，切换成功
 
3，再切换回去
 
注意：在主库没有切换成备库时，standby数据切换状态为
SQL> select switchover_status from v$database;

SWITCHOVER_STATUS

--------------------

NOT ALLOWED
重复上面的步骤
 
1）连接当前的主库
SQL> select database_role from v$database;

DATABASE_ROLE

----------------

PRIMARY

SQL> select switchover_status from v$database;

SWITCHOVER_STATUS

--------------------

TO STANDBY

SQL> alter database commit to switchover to physical standby with session shutdown;

Database altered.

SQL> shutdown immediate

ORA-: database not mounted

ORACLE instance shut down.

SQL> startup nomount

ORACLE instance started.

Total System Global Area   bytes

Variable Size              bytes

Database Buffers           bytes

Redo Buffers                 bytes

SQL> alter database mount standby database;

Database altered.

SQL> select database_role from v$database;

DATABASE_ROLE

----------------

PHYSICAL STANDBY

SQL>  alter database recover managed standby database disconnect from session parallel ;

Database altered.

SQL> select switchover_status from v$database;

SWITCHOVER_STATUS

--------------------

SESSIONS ACTIVE   --备库没有切换
2）连接当前的备库
SQL> select database_role from v$database;

DATABASE_ROLE

----------------

PHYSICAL STANDBY

SQL> select switchover_status from v$database;

SWITCHOVER_STATUS

--------------------

TO PRIMARY    ---此时的状态变为TO PRIMARY

SQL> alter database commit to switchover to primary with session shutdown ;

Database altered.

SQL> shutdown immediate

ORA-: database not open

Database dismounted.

ORACLE instance shut down.

SQL> startup

ORACLE instance started.

Total System Global Area   bytes

Fixed Size                   bytes

Variable Size              bytes

Database Buffers           bytes

Redo Buffers                 bytes

Database mounted.

Database opened.

SQL> select database_role from v$database;

DATABASE_ROLE

----------------

PRIMARY
此时再查看备库的切换状态
 
连接备库
SQL> select switchover_status from v$database;

SWITCHOVER_STATUS

--------------------

NOT ALLOWED
六，问题总结
 
配置完成后，在主库的alert日志里报下面的错误：

Thu Apr  ::

日志没有被应用，密码文件创建完全一样
orapwd file=orapwPRODDG force=y password=oracle entries=

orapwd file=orapwPROD force=y password=oracle entries=
依然不行，
 
最后创建好，主库的密码文件后，拷贝主库的密码文件到备库，问题解决！！！！很奇怪！！！！
