能select的表,可以exp吗?有exp_full_database就能exp其他用户的表吗?
 
下面来测试下:
 
1.建立导出测试用户,并授予相关权限
[oracle@GXDB1] $sqlplus /nolog
SQL*Plus: Release 10.2.0.4.0 - Production on Fri May 3 15:11:19 2013
Copyright (c) 1982, 2007, Oracle.  All Rights Reserved.
SQL> conn / as sysdba
Connected.
SQL> create user test_exp identified by a;
User created.
SQL> grant connect to test_exp;
Grant succeeded.
SQL> grant select on dep_study.bas_region to test_exp;
Grant succeeded.
 
2.导出dep_study.bas_region表
[oracle@GXDB1] $exp test_exp/a@gxtest file=a.dmp tables=dep_study.bas_region
Export: Release 10.2.0.4.0 - Production on Fri May 3 15:26:15 2013

[oracle@GXDB1] $
 
3.给test_exp授予exp_full_database权限
SQL> grant exp_full_database to test_exp;
Grant succeeded.
 
4.成功导出表
[oracle@GXDB1] $exp test_exp/a@gxtest file=a.dmp tables=dep_study.bas_region
Export: Release 10.2.0.4.0 - Production on Fri May 3 15:29:20 2013

About to export specified tables via Conventional Path ...
Current user changed to DEP_STUDY
. . exporting table                     BAS_REGION         17 rows exported
Export terminated successfully without warnings.
--ok 成功导出
 
5.收回select权限,并导出表
SQL>  revoke select on dep_study.bas_region from test_exp;
Revoke succeeded.
[oracle@GXDB1] $exp test_exp/a@gxtest file=a.dmp tables=dep_study.bas_region
Export: Release 10.2.0.4.0 - Production on Fri May 3 15:32:15 2013

Export done in ZHS16GBK character set and UTF8 NCHAR character set
About to export specified tables via Conventional Path ...
Current user changed to DEP_STUDY
. . exporting table                     BAS_REGION
EXP-00056: ORACLE error 1031 encountered
ORA-01031: insufficient privileges
Export terminated successfully with warnings.

结论:
    exp其他用户的表,用户需要拥有select表和exp_full_database(角色)两个权限。
