2.使用RMAN的COPY功能备份裸设备文件为文件系统文件

[oracle@danaly ~]$ rman target /

Recovery Manager: Release 10.2.0.1.0 - Production on Wed Nov 30 16:00:42 2005

connected to target database: DANALY (DBID=3965153484)

RMAN> copy datafile ‘/dev/cciss/c0d0p11‘ to ‘/opt/oracle/eygle01.dbf‘;

Starting backup at 30-NOV-05

using target database control file instead of recovery catalog

allocated channel: ORA_DISK_1

channel ORA_DISK_1: sid=137 devtype=DISK

channel ORA_DISK_1: starting datafile copy

input datafile fno=00002 name=/dev/cciss/c0d0p11

output filename=/opt/oracle/eygle01.dbf tag=TAG20051130T160137 recid=2 stamp=575740898

channel ORA_DISK_1: datafile copy complete, elapsed time: 00:00:02

Finished backup at 30-NOV-05

RMAN> exit

Recovery Manager complete.

3.通过rename修改文件位置

[oracle@danaly ~]$ sqlplus "/ as sysdba"

SQL*Plus: Release 10.2.0.1.0 - Production on Wed Nov 30 16:01:54 2005

Connected to:

Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production

With the Partitioning, Oracle Label Security, OLAP and Data Mining Scoring Engine options

SQL> alter database rename file ‘/dev/cciss/c0d0p11‘ to ‘/opt/oracle/eygle01.dbf‘;

Database altered.

SQL> alter tablespace eygle online;

Tablespace altered.

SQL> select file_name from dba_data_files where tablespace_name=‘EYGLE‘;

FILE_NAME

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

/opt/oracle/eygle01.dbf

4.进行数据修改

SQL> insert into eygle as select * from eygle;

insert into eygle as select * from eygle *

ERROR at line 1:

ORA-00926: missing VALUES keyword

SQL> insert into eygle select * from eygle;

insert into eygle select * from eygle

ERROR at line 1:

ORA-01653: unable to extend table SYS.EYGLE by 128 in tablespace EYGLE

SQL> alter database datafile ‘/opt/oracle/eygle01.dbf‘ resize 20m;

Database altered.

SQL> insert into eygle select * from eygle;

50420 rows created.
