oracle11g ora 29927,Oracle11gR2使用RMANDuplicate复制数据库
四、安裝軟件并創建數據庫
./runInstaller -silent -debug -force -responseFile /home/oracle/database/response/db_install.rsp
dbca -silent -responsefile /home/oracle/database/response/dbca.rsp
五、開啟歸檔
SQL> alter system set log_archive_dest_1='location=+FRA001/archive' scope=spfile sid='woo1';
System altered.
SQL> alter database archivelog;
Database altered.
SQL> alter database open;
Database altered.
SQL> archive log list;
Database log mode Archive Mode
Automatic archival Enabled
Archive destination +FRA001/archive
Oldest online log sequence 978
Next log sequence to archive 979
Current log sequence 979
SQL> alter system switch logfile;
alter system switch logfile;

SQL> archive log list;

Archive destination +FRA001/archive
Oldest online log sequence 980
Next log sequence to archive 981
Current log sequence 981
六、配置靜態監聽
RAC節點監聽信息如下:
$ cd $ORACLE_HOME/network/admin
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = scan.woo.com)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = woo.com)
(ORACLE_HOME = /DBSoft/oracle/product/11.2.0/db_1)
(SID_NAME = woo)
)
)
ADR_BASE_LISTENER = /DBSoft/oracle
單節點監聽信息如下:
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.7.55)(PORT = 1521))
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1521))
)
)
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(GLOBAL_DBNAME = woo.com)
(ORACLE_HOME = /DBSoft/oracle/product/11.2.0/db_1)
(SID_NAME = woo)
)
)
ADR_BASE_LISTENER = /DBSoft/oracle
配置所有節點tnsname信息如下:
WOO =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = scan.woo.com)(PORT = 1521))
)
(CONNECT_DATA =
(SERVICE_NAME = woo)
)
)
DUPLICATE =
(DESCRIPTION =
(ADDRESS_LIST =
(ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.7.55)(PORT = 1521))
)
(CONNECT_DATA =
(SERVER = DEDICATED)
(SERVICE_NAME = woo)
)
)
六、啟動數據庫到nomount狀態
SQL> startup nomount
ORA-32004: obsolete or deprecated parameter(s) specified for RDBMS instance
ORACLE instance started.

SQL>exit ---------必須退出

七、 在RAC端任意節點通過RMAN連接到目標實例和輔助實例，執行duplicate命令復制數據庫：

注意:這里的nofilenamecheck參數需要解釋下:
如果在復制時，位置不同時，我們會用參數db_file_name_convert 對文件位置進行轉換。 但是在這個復制示例中我們用的是相同的位置。 所以這里必須加上nofilenamecheck參數。 該參數通知復制操作不必在執行還原操作前確認文件名是不同的。如果沒有指定nofilenamecheck參數，rman會給出如下錯誤：
RMAN-05001: auxiliary filename /DBSoft/oracle/oradata/woo/users01.dbf conflicts with a file used by the target database
