11g 使用rman duplicate复制数据库，创建辅助实例 / 憋错料

一，创建所需目录

1）创建审计文件目录

[email protected]  /dsg/oracle11$ cd $ORACLE_BASE/admin

[email protected]  /u01/app/oracle/admin$ mkdir -p PROD1/adump

2）创建数据文件目录

mkdir -p /dsg/oracle11/PROD1

二，创建参数文件和密码文件

这里，复制主库的参数文件和密码文件，参数文件稍作修改

[email protected] /dsg$ export ORACLE_SID=PROD
[email protected] /dsg$ sqlplus / as sysdba

SQL*Plus: Release 11.2.0.1.0 Production on Tue Apr 29 14:00:54 2014

Oracle Database 11g Enterprise Edition Release 11.2.0.1.0 - 64bit Production
With the Partitioning, Real Application Clusters, OLAP, Data Mining
and Real Application Testing options

[email protected] /dsg$ cd $ORACLE_HOME/dbs
[email protected] /u01/app/oracle/product/11.2.0/dbs$ cp initPROD.ora initPROD1.ora
#复制密码文件

[email protected]  /u01/app/oracle/product/11.2.0/dbs$ cp orapwPROD orapwPROD1

修改参数文件

PROD1.__db_cache_size=272629760

PROD1.__java_pool_size=4194304

PROD1.__large_pool_size=4194304

PROD1.__oracle_base=‘/u01/app/oracle‘#ORACLE_BASE set from environment

PROD1.__pga_aggregate_target=3812622336

PROD1.__sga_target=536870912

PROD1.__shared_io_pool_size=0

PROD1.__shared_pool_size=243269632

PROD1.__streams_pool_size=0

*.audit_file_dest=‘/u01/app/oracle/admin/PROD1/adump‘

*.audit_trail=‘db‘

*.compatible=‘11.2.0.0.0‘

*.control_files=‘/dsg/oracle11/PROD1/control01.ctl‘,‘/dsg/oracle11/PROD1/control02.ctl‘

*.db_block_size=32768

*.DB_NAME=‘PROD1‘    ###如果辅助实例在同一台服务器上，DB_NAME不能相同

*.DB_UNIQUE_NAME=‘PROD1‘

*.diagnostic_dest=‘/u01/app/oracle‘

*.dispatchers=‘(PROTOCOL=TCP) (SERVICE=PROD1XDB)‘

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

*.sga_target=536870912

*.STANDBY_FILE_MANAGEMENT=‘AUTO‘

*.undo_tablespace=‘UNDOTBS1‘
###下面两个参数可选，但是推荐使用，如果不使用可以在rman的run块中指定恢复的目录

*.DB_FILE_NAME_CONVERT=‘/dsg/oracle11/PROD‘,‘/dsg/oracle11/PROD1‘

*.LOG_FILE_NAME_CONVERT=‘/dsg/oracle11/PROD‘,‘/dsg/oracle11/PROD1‘

三，配置监听及TNS

这里，使用静态监听

vi listener.ora

 (ADDRESS_LIST=

      (ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.70)(PORT=1521))

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

  (SID_LIST=

      (SID_DESC=

         (GLOBAL_DBNAME=PROD)

         (SERVICE_NAME = PROD)

         (SID_NAME=PROD)

         (ORACLE_HOME=/u01/app/oracle/product/11.2.0)

        (PRESPAWN_MAX=20)

        (PRESPAWN_LIST=

          (PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=2)(TIMEOUT=1))

        )

       )

        (SID_DESC=

         (GLOBAL_DBNAME=PROD1)

         (SERVICE_NAME = PROD1)

         (SID_NAME=PROD1)

         (ORACLE_HOME=/u01/app/oracle/product/11.2.0)

        (PRESPAWN_MAX=20)

        (PRESPAWN_LIST=

          (PRESPAWN_DESC=(PROTOCOL=tcp)(POOL_SIZE=2)(TIMEOUT=1))

        )

       )

 )

tnsnames.ora添加

PROD =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.70)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = PROD)

    )

  )
PROD1 =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.1.70)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = PROD1)

    )

  )

####重启监听

lsnrctl reload

四，启动辅助实例

启动辅助实例到nomount模式，也只能启动到nomount，一定要使用spfile参数文件

六，总结及遇到的问题

1，在rman中恢复的时候总是报数据库名不一致，原来在同一个服务器上db_name不能相同且必须使用spfile

RMAN-00571: ===========================================================

RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-00571: ===========================================================

RMAN-03002: failure of Duplicate Db command at 04/29/2014 15:21:38

RMAN-05520: database name mismatch, auxiliary instance has PROD, command specified PROD1

2，如果目标库与副本数据库的在线日志文件和数据文件路径不相同，则需要像本文一样配置db_file_name_convert和log_file_name_convert，否则会报错rman-06023

3，要是不配置db_file_name_convert和log_file_name_convert，可以通过如下命令达到相同的目的

RUN

{

# The DUPLICATE command uses an automatic sbt channel.

# Because the target datafiles are spread across multiple directories,

# run SET NEWNAME rather than DB_FILE_NAME_CONVERT

SET NEWNAME FOR DATAFILE 1 TO ‘/oradata1/system01.dbf‘;

SET NEWNAME FOR DATAFILE 2 TO ‘/oradata2/undotbs01.dbf‘;

SET NEWNAME FOR DATAFILE 3 TO ‘/oradata3/cwmlite01.dbf‘;

SET NEWNAME FOR DATAFILE 4 TO ‘/oradata4/drsys01‘;

SET NEWNAME FOR DATAFILE 5 TO ‘/oradata5/example01.dbf‘;

SET NEWNAME FOR DATAFILE 6 TO ‘/oradata6/indx01.dbf‘;

# Do not set a newname for datafile 7, because it is in the tools tablespace,

# and you are excluding tools from the duplicate database.

SET NEWNAME FOR DATAFILE 8 TO ‘/oradata7/users01.dbf‘;

DUPLICATE TARGET DATABASE TO dupdb

SKIP TABLESPACE tools

LOGFILE

GROUP 1 (‘/duplogs/redo01a.log‘,

‘/duplogs/redo01b.log‘) SIZE 200K REUSE,

GROUP 2 (‘/duplogs/redo02a.log‘,

‘/duplogs/redo02b.log‘) SIZE 200K REUSE;

}

上面的命令还使用过SKIP TABLESPACE子句跳过指定表空间

另外还可以使用CONFIGURE AUXNAME 命令重命名数据文件，复制步骤如下：

#configurethenewdesiredfilenames

CONFIGURE AUXNAME FOR DATAFILE 1 TO ‘F:\oracle\oradata\jssdup\system01.dbf‘;

CONFIGURE AUXNAME FOR DATAFILE 2 TO ‘F:\oracle\oradata\jssdup\undotbs01.dbf‘;

#...addmoreCONFIGUREAUXNAMEcommandsasneeded

不过需要注意的是，duplicate执行完之后，推荐清除CONFIGUREAUXNAME。这样就不会对未来的

类似操作造成影响。

#clearspecifiedauxiliarynamesforthedatafiles

CONFIGURE AUXNAME FOR DATAFILE 1 CLEAR;

CONFIGURE AUXNAME FOR DATAFILE 2 CLEAR;

如果副本数据库与目标库不在同一台机器上，并且副本数据库的在线日志文件路径与目标库相同，NOFILENAMECHECK

则运行duplicate命令时必须指定NOFILENAMECHECK参数以避免冲突提示。此处oracle表现的很傻，它不知道你要恢复的路径是在另一台机器上，它只是认为要恢复到的路径怎么跟目标数据库表现的一样呢？会不会是要覆盖目标数据库啊，为了避免这种情形，于是它就报错。所以一旦异机恢复，并且路径相同，那么你必须通过指定NOFILENAMECHECK来避免oracle的自动识别。这里NOFILENAMECHECK不是必须的

4）如果备份文件保存在磁盘上，分配的通道越多则速度越快，如果备份文件在磁带上，最少指定设备数量个通道。

七，使用备份恢复辅助实例

1）在同一服务器上

先备份数据库

backup database plus archivelog ;

然后恢复

RUN
{
# The DUPLICATE command uses an automatic sbt channel.
# Because the target datafiles are spread across multiple directories,

allocate channel prmy1 type disk;
allocate channel prmy2 type disk;
allocate channel prmy3 type disk;
allocate channel prmy4 type disk;

ALLOCATE AUXILIARY CHANNEL aux1 DEVICE TYPE DISK;
ALLOCATE AUXILIARY CHANNEL aux2 DEVICE TYPE DISK;
ALLOCATE AUXILIARY CHANNEL aux3 DEVICE TYPE DISK;

# run SET NEWNAME rather than DB_FILE_NAME_CONVERT
SET NEWNAME FOR DATAFILE 1 TO ‘/dsg/oracle11/PROD1/system01.dbf‘;
SET NEWNAME FOR DATAFILE 2 TO ‘/dsg/oracle11/PROD1/sysaux01.dbf‘;
SET NEWNAME FOR DATAFILE 3 TO ‘/dsg/oracle11/PROD1/undotbs01.dbf‘;
SET NEWNAME FOR DATAFILE 4 TO ‘/dsg/oracle11/PROD1/users01.dbf‘;
SET NEWNAME FOR TEMPFILE 1 TO ‘/dsg/oracle11/PROD1/temp01.dbf‘;
# Do not set a newname for datafile 7, because it is in the tools tablespace,
# and you are excluding tools from the duplicate database.
DUPLICATE TARGET DATABASE TO PROD1
LOGFILE
GROUP 1 (‘/dsg/oracle11/PROD1/redo01a.log‘,‘/dsg/oracle11/PROD1/redo01b.log‘) SIZE 50M REUSE,
GROUP 2 (‘/dsg/oracle11/PROD1/redo02a.log‘,‘/dsg/oracle11/PROD1/redo02b.log‘) SIZE 50M REUSE,
GROUP 3 (‘/dsg/oracle11/PROD1/redo03a.log‘,‘/dsg/oracle11/PROD1/redo03b.log‘) SIZE 50M REUSE;
}

2）在不同的服务器

拷贝源数据库的备份集到和源数据库放置备份集相同的目录下，或者NFS挂载到相同的目录下再执行上面的操作
