Oracle 11gR2利用RMAN复制整库记录

源端和目标端配置好TNS和监听（11g动态监听sys无法在nomount状态登入，需配置静态监听）

[oracle@154-Oracle_Archive admin]$ vi tnsnames.ora

TESTHIS.154 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.234.154)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = TESTHIS)
)
)

TESTHIS.11 =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.234.11)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SID = testhisnew)
)
)

[oracle@154-Oracle_Archive admin]$ vi listener.ora

# listener.ora Network Configuration File: /opt/app/oracle/product/11.2.0/dbhome_1/network/admin/listener.ora
# Generated by Oracle configuration tools.

LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 154-Oracle_Archive.hubs1.pu)(PORT = 1521))
)
)

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(PROGRAM = extproc)
)
(SID_DESC =
(GLOBAL_DBNAME = testhis
(ORACLE_HOME = /u01/app/oracle/product/11.2.0/dbhome_1)
(SID_NAME = testhis)
)
)

源库创建pfile

SQL> create pfile='/home/oracle/pfile.ora' from spfile;

File created.

将源库的pfile、listener、tnsname、orapw文件传输到目标库的指定位置并加以修改

[oracle@154-Oracle_Archive admin]$ scp *.ora root@192.168.234.11:/u01/app/oracle/product/11.2.0/dbhome_1/network/admin
root@192.168.234.11's password:
listener.ora 100% 619 0.6KB/s 00:00
tnsnames.ora 100% 448 0.4KB/s 00:00

[oracle@154-Oracle_Archive ~]$ scp pfile.ora root@192.168.234.11:/home/oracle
root@192.168.234.11's password:
pfile.ora 100% 1018 1.0KB/s 00:00

[oracle@154-Oracle_Archive dbs]$ scp orapwtesthis root@192.168.234.11:/home/oracle
root@192.168.234.11's password:
Permission denied, please try again.
root@192.168.234.11's password:
orapwtesthis 100% 1536 1.5KB/s 00:00

[oracle@Oracle_archive ~]$ cp orapwtesthis /u01/app/oracle/product/11.2.0/dbhome_1/dbs/orapwtesthisnew

修改pfile文件

[oracle@Oracle_archive ~]$ vi pfile.ora

log_file_name_convert=('/u01/app/oracle/oradata/testhis/','/u01/app/oracle/oradata/testhisnew/'）

创建相关目录

[oracle@Oracle_archive ~]$ mkdir -p /u01/app/oracle/admin/testhis_n/adump
[oracle@Oracle_archive ~]$ mkdir -p /u01/app/oracle/oradata/testhis_n/
[oracle@Oracle_archive ~]$ mkdir -p /u01/app/oracle/fast_recovery_area/testhis_n/

登入数据库创建spfile并启动实例

[oracle@Oracle_archive ~]$ echo $ORACLE_SID
testhisnew
[oracle@Oracle_archive ~]$ sqlplus / as sysdba

源端登入两数据库，执行复制

[oracle@154-Oracle_Archive admin]$ rman target sys/******@testhis.154 auxiliary sys/******@testhis.11

复制完成后启动关闭目标库，验证是否复制成功，并观察alter日志是否有报错日志，确认无误后及时做全库备份。
