發布時間：2024/4/14 编程问答 26 豆豆

生活随笔收集整理的這篇文章主要介紹了 Oracle备份恢复之逻辑备份小編覺得挺不錯的,現在分享給大家,幫大家做個參考.

exp

交互模式：導出scott用戶下的emp表。

[oracle@localhost ~]$ exp

Export: Release 10.2.0.1.0 - Production on Thu Nov 27 12:27:45 2014

Username: scott

Password:

Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production

With the Partitioning, OLAP and Data Mining options

Enter array fetch buffer size: 4096 >

Export file: expdat.dmp > /u01/oracle/text.dmp

(2)U(sers), or (3)T(ables): (2)U > T

Export table data (yes/no): yes >

Compress extents (yes/no): yes >

Export done in US7ASCII character set and AL16UTF16 NCHAR character set

server uses ZHS16GBK character set (possible charset conversion)

About to export specified tables via Conventional Path ...

Table(T) or Partition(T:P) to be exported: (RETURN to quit) > emp

. . exporting table EMP 14 rows exported

EXP-00091: Exporting questionable statistics.

Table(T) or Partition(T:P) to be exported: (RETURN to quit) >

Export terminated successfully with warnings.

命令行模式：導出scott用戶下的emp表。導出多張表需要用，或空格分隔開。

[oracle@localhost ~]$ exp scott/tiger file=/u01/oracle/test1.dmp tables=emp

Export: Release 10.2.0.1.0 - Production on Thu Nov 27 12:33:33 2014

Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production

With the Partitioning, OLAP and Data Mining options

Export done in US7ASCII character set and AL16UTF16 NCHAR character set

server uses ZHS16GBK character set (possible charset conversion)

About to export specified tables via Conventional Path ...

. . exporting table EMP 14 rows exported

EXP-00091: Exporting questionable statistics.

Export terminated successfully with warnings.

按照方案的形式把scott用戶下的數據全部導出。

[oracle@localhost ~]$ exp scott/tiger file=/u01/oracle/test9.dmp owner=scott

Export: Release 10.2.0.1.0 - Production on Thu Nov 27 12:37:02 2014

Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production

With the Partitioning, OLAP and Data Mining options

Export done in US7ASCII character set and AL16UTF16 NCHAR character set

server uses ZHS16GBK character set (possible charset conversion)

. . exporting table BONUS 0 rows exported

EXP-00091: Exporting questionable statistics.

. . exporting table DEPT 4 rows exported

EXP-00091: Exporting questionable statistics.

. . exporting table EMP 14 rows exported

EXP-00091: Exporting questionable statistics.

. exporting posttables actions

. exporting materialized views

. exporting snapshot logs

. exporting job queues

. exporting refresh groups and children

. exporting dimensions

. exporting post-schema procedural objects and actions

. exporting statistics

Export terminated successfully with warnings.

用sys用戶導出scott用戶下所有數據。

[oracle@localhost ~]$ exp \'sys/tiger as sysdba\' file=/u01/oracle/test8.dmp owner=scott

Export: Release 10.2.0.1.0 - Production on Thu Nov 27 12:42:11 2014

Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production

With the Partitioning, OLAP and Data Mining options

Export done in US7ASCII character set and AL16UTF16 NCHAR character set

server uses ZHS16GBK character set (possible charset conversion)

About to export specified users ...

. exporting pre-schema procedural objects and actions

. exporting foreign function library names for user SCOTT

. exporting PUBLIC type synonyms

. exporting private type synonyms

About to export SCOTT's objects ...

. exporting database links

. about to export SCOTT's tables via Conventional Path ...

. . exporting table BONUS 0 rows exported

EXP-00091: Exporting questionable statistics.

. . exporting table DEPT 4 rows exported

EXP-00091: Exporting questionable statistics.

. . exporting table EMP 14 rows exported

EXP-00091: Exporting questionable statistics.

. . exporting table SALGRADE 5 rows exported

EXP-00091: Exporting questionable statistics.

. exporting job queues

. exporting refresh groups and children

. exporting dimensions

. exporting post-schema procedural objects and actions

. exporting statistics

Export terminated successfully with warnings.

如果到處文件過大，可以指定多個導出文件。

>exp scott/tiger file=/u01/oracle/test1.dmp,/u01/oracle/test2.dmp filesize=1g tables=emp dept log=/u01/oracle/20141128.log

[oracle@localhost ~]$ exp scott/tiger file=/u01/oracle/test1.dmp,/u01/oracle/test2.dmp filesize=1g tables=emp dept log=/u01/oracle/20141128.log

Export: Release 10.2.0.1.0 - Production on Thu Nov 27 12:51:18 2014

Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - Production

With the Partitioning, OLAP and Data Mining options

Export done in US7ASCII character set and AL16UTF16 NCHAR character set

server uses ZHS16GBK character set (possible charset conversion)

About to export specified tables via Conventional Path ...

. . exporting table EMP 14 rows exported

EXP-00091: Exporting questionable statistics.

. . exporting table DEPT 4 rows exported

EXP-00091: Exporting questionable statistics.

Export terminated successfully with warnings.

使用具備dba權限的用戶進行全庫導出。

exp \'sys/tiger@orcl as sysdba\' file=/u01/oracle/full.dmp,/u01/oracle/fulll.dmp filesize=100m full=y

參數文件導出：

[oracle@localhost oracle]$ vi p1

[oracle@localhost oracle]$ exp parfile p1

[oracle@localhost oracle]$ vi p1

userid=scott/tiger

file=/u01/oracle/pfile.dmp

tables=emp

[oracle@localhost oracle]$ exp parfile=p1

query參數導出符合的數據：

userid=scott/tiger

file=/u01/dddd.dmp

tables=emp

query='where deptno in (10,20)'

imp

表不存在導入方式：imp scott/tiger file=/u01/oracle/scott.dmp tables=emp,dept

表存在的導入方式：imp scott/tiger file=/u01/scott.dmp tables=emp ignore=y

imp scott/tiger file=/u01/oracle/scott.dmp fromuser=v7hqs touser=v7hqs log=2014

將scott用戶emp表導入s1用戶：

imp system/tiger fromuser=scott touser=s1 file=/u01/oracle/scott.dmp tables=emp
