最近有个小数据库中某用户下的所有数据需要迁移到另外一个，现在先模拟下：
数据量并不是很大的情况下，这里使用exp导出该用户下的所有数据对象：
[lubinsu@localhost orcl]$ exp lubinsu/lubinsu@orcl_03 file=/home/lubinsu/orcl/lubinsu.dmp log=/home/lubinsu/orcl/lubinsu.log owner=lubinsu compress=n 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 ZHS16GBK character set and AL16UTF16 NCHAR character set About to export specified users ... . exporting pre-schema procedural objects and actions . exporting foreign function library names for user LUBINSU . exporting PUBLIC type synonyms . exporting private type synonyms . exporting object type definitions for user LUBINSU About to export LUBINSU's objects ... . exporting database links . exporting sequence numbers . exporting cluster definitions . about to export LUBINSU's tables via Conventional Path ... . . exporting table AREA_TM 33105 rows exported . . exporting table BSS_PO_SPEC_D 26570 rows exported . . exporting table CRM_BASE_BUSI_ORDER 10000 rows exported . . exporting table DEPT 4 rows exported . . exporting table EMP 14 rows exported . . exporting table GRID_MSG 156588 rows exported . . exporting table JOB_PARMS 0 rows exported . . exporting table LATN_AREA_INFO 14 rows exported . . exporting table MANAGER_TM 66140 rows exported . . exporting table MANAGER_TM_T 65994 rows exported . . exporting table PO_SPEC_CATE_TREE_RELA 578 rows exported . . exporting table PROCEDURE_RESULT 15 rows exported . . exporting table SERV_MSG . . exporting partition P_PROVINCE 0 rows exported . . exporting partition P_NJ 10008 rows exported . . exporting partition P_WX 10008 rows exported . . exporting partition P_ZJ 10008 rows exported . . exporting partition P_SZ 10008 rows exported . . exporting partition P_NT 10008 rows exported . . exporting partition P_YZ 10008 rows exported . . exporting partition P_YC 10008 rows exported . . exporting partition P_XZ 10008 rows exported . . exporting partition P_HA 10008 rows exported . . exporting partition P_LYG 10008 rows exported . . exporting partition P_CZ 10008 rows exported . . exporting partition P_TZ 10008 rows exported . . exporting partition P_SQ 10008 rows exported . . exporting table STAT_PROCEDURE 163 rows exported . . exporting table TEACHER_VPN_STAT_DAILY 2377 rows exported . . exporting table TEACHER_VPN_STAT_DAILY_T 65 rows exported . . exporting table TT4 49880 rows exported . . exporting table T_SCN 18 rows exported . . exporting table T_TEST 393800 rows exported . . exporting table T_TEST_1 49894 rows exported . . exporting table T_TEST_2 49895 rows exported . exporting synonyms . exporting views . exporting stored procedures . exporting operators . exporting referential integrity constraints . exporting triggers . exporting indextypes . exporting bitmap, functional and extensible indexes . 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 without warnings.
然后直接导入到目标库的目标用户下，进行的还是比较顺利的，在这过程中可能会报无法创建文件等错误，请注意权限问题：

如果只要导出数据库结构而不导出数据，则（加参数rows=n）：
[lubinsu@localhost orcl]$ exp lubinsu/lubinsu@orcl_03 file=/home/lubinsu/orcl/lubinsu.dmp rows=n log=lubinsu_exp.log Export: Release 10.2.0.1.0 - Production on Sat Jun 15 16:14:41 2013 Copyright (c) 1982, 2005, Oracle.
