  Oracle DBMS_FILE_TRANSFER可以实现文件系统和ASM磁盘组之间实现文件传输及ASM磁盘组之间跨网络的传输。

DBMS_FILE_TRANSFER:

    The DBMS_FILE_TRANSFER package provides procedures to copy a binary file within a database or to transfer a binary file between databases.

案例1:

文件系统与ASM磁盘组之间文件传送:

1、查看datafile存储信息

SQL> select name from v$datafile;
NAME
--------------------------------------------------------------------------------
+DG1/prod/datafile/system.256.852292703
+DG1/prod/datafile/sysaux.257.852292707
+DG1/prod/datafile/undotbs1.258.852292707
+DG1/prod/datafile/users.259.852292709
+DG1/prod/datafile/example.264.852292891
+DG1/prod/datafile/undotbs2.265.852293259
6 rows selected.

2、建立传输目录

建立Oracle directory(ASM存储)

SQL> create directory asm_dir as '+DG1/prod/datafile';

Directory created.

建立Oracle directory(文件系统

[root@node2 ~]# mkdir /u01/bak

[root@node2 ~]# chown  oracle:dba /u01/bak

SQL> create directory fs_dir as '/u01/bak';

Directory created.

3、表空间做热备

16:04:26 SYS@ prod1>alter tablespace users begin backup;

Tablespace altered.

备份ASM磁盘组文件到文件系统:

SQL> exec dbms_file_transfer.copy_file('ASM_DIR','users.259.852292709','FS_DIR','users01.dbf');

PL/SQL procedure successfully completed.

参数信息:

1、源文件目录

2、源文件名

3、目标文件目录

4、目标文件

16:04:36 SYS@ prod1>alter tablespace users end backup;

Tablespace altered.

4、验证文件传送情况

[oracle@node2 ~]$ ls -lh /u01/bak

total 5.1M

-rw-r----- 1 oracle asmadmin 5.1M Jul  7 17:18 users01.dbf

文件传送成功!

5、从文件系统传送文件到ASM磁盘组

16:07:51 SYS@ prod2>exec dbms_file_transfer.copy_file('FS_DIR','users01.dbf' ,'ASM_DIR','TEST01.DBF');

PL/SQL procedure successfully completed.

Elapsed: 00:00:02.25

6、验证文件传送

ASMCMD>cd +dg1/prod/datafile

ASMCMD> ls

COPY_FILE.272.852394075

EXAMPLE.264.852292891

SYSAUX.257.852292707

SYSTEM.256.852292703

TBS1.269.852376681

TEST01.DBF

UNDOTBS1.258.852292707

UNDOTBS2.265.852293259

USERS.259.852387481

文件传送成功!

案例2:

跨网络从ASM磁盘组传输文件到ASM磁盘组


案例环境:

NODE1:

操作系统: Linux EL5

Oracle:   Oracle 10gR2

NODE2:

操作系统: Linux EL5

Oracle:   Oracle 11gR2


1、配置database link

NODE1:

TNSNAMES.ORA:

TEST =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.8.239)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = test1asm)

    )

  )

配置db-link:

16:25:21 SYS@ prod2>create public database link

16:25:35   2  test connect to scott identified by tiger using 'TEST';

Database link created.

验证db-link

16:26:01 SYS@ prod2>select * from emp@test;

 EMPNO ENAME      JOB              MGR HIREDATE         SAL       COMM     DEPTNO
---------- ---------- --------- ---------- --------- ---------- ---------- ----------

      7934 MILLER     CLERK           7782 23-JAN-82       1300                    10
14 rows selected.

2、创建文件传输目录(node2)

16:23:59 SYS@ test1asm>select name from v$datafile;
NAME
-----------------------------------------------------------------------------------------
+DG1/test1asm/datafile/system01.dbf
+DG1/test1asm/datafile/undotbs01.dbf
+DG1/test1asm/datafile/sysaux01.dbf
+DG1/test1asm/datafile/users01.dbf
Elapsed: 00:00:00.15

16:24:08 SYS@ test1asm>create directory test_asm as '+dg1/test1asm/datafile';

Directory created.

Elapsed: 00:00:00.11

16:36:24 SYS@ test1asm>grant read ,write on directory test_asm to public;

Grant succeeded.

3、从node1上传文件到node2

16:40:14 SYS@ prod2>exec dbms_file_transfer.put_file('ASM_DIR','TEST01.DBF','test_asm','TEST001.DBF','TEST');

PL/SQL procedure successfully completed.

参数信息:

1、源文件目录

2、源文件

3、目标文件目录

4、目标文件

5、db-link

4、验证文件传输

ASMCMD> cd datafile

ASMCMD> ls

FILE_TRANSFER.266.852395843

SYSAUX.259.848848797

SYSTEM.258.848848793

TEST001.DBF

UNDOTBS1.260.848848799

USERS.261.848848801

sysaux01.dbf

system01.dbf

undotbs01.dbf

users01.dbf

文件传输成功!

5、配置NODE2 DATABASE LINK

TNSNAMES.ORA:

PROD2 =

  (DESCRIPTION =

    (ADDRESS = (PROTOCOL = TCP)(HOST = 192.168.8.24)(PORT = 1521))

    (CONNECT_DATA =

      (SERVER = DEDICATED)

      (SERVICE_NAME = TAF)

    )

  )

故障案例:

文件传输出现以下错误:

16:34:06 SYS@ prod2>exec dbms_file_transfer.put_file('ASM_DIR','TEST01.DBF','TEST_ASM','TEST001.DBF','TEST');

BEGIN dbms_file_transfer.put_file('ASM_DIR','TEST01.DBF','TEST_ASM','TEST001.DBF','TEST'); END;

*

ERROR at line 1:

ORA-06564: object TEST_ASM does not exist

ORA-02063: preceding line from TEST
