Question

我想使用expdp和impdp命令在两个用户之间传输oracle表。

首先，我创建了一个目录并为源用户和目标用户授予了适当的特权：

SQL> CREATE OR REPLACE DIRECTORY TEST_DIR AS '/u01/app/oracle/oradata/temp_dirs';
Directory created.
SQL> GRANT READ, WRITE ON DIRECTORY test_dir TO SOURCE_USER;
Grant succeeded.
SQL> GRANT READ, WRITE ON DIRECTORY test_dir TO DEST_USER;
Grant succeeded.
SQL> commit;

这是我的expdp命令，它的输出是：

oracle@lab-57:~$ expdp SOURCE_USER/SOURCE_USER tables=tbl_user directory=TEST_DIR dumpfile=users.dmp logfile=exp_users.log

这意味着导出操作已成功完成。

然后我尝试使用impdp导入它，如下所示：

oracle@lab-57:~$ impdp DEST_USER/DEST_USER tables=TBL_USER directory=TEST_DIR dumpfile=users.dmp logfile=imp_users.log

ORA-39002: invalid operation
ORA-39166: Object DEST_USER.TBL_USER was not found.

我还尝试了tables=DEST_USER.TBL_USER和content=data_only；都返回相同的错误。

Answer 1

当您导出为SOURCE_USER并导入为DEST_USER时，REMAP_SCHEMA参数可能会有所帮助。（我将命令分成几行以便于阅读）

impdp DEST_USER/DEST_USER tables=TBL_USER directory=TEST_DIR 
dumpfile=users.dmp logfile=imp_users.log
remap_schema=source_user:dest_user             --> this

如果您使用的是11.2，则可能会遇到一个错误，该错误将不允许您执行此操作（有关更多信息，请参见My Oracle Support）。在这种情况下，您仍然可以执行导入，但是必须省略TABLES参数，即

                          TABLES was in this gap
                                 |
impdp DEST_USER/DEST_USER        v       directory=TEST_DIR 
dumpfile=users.dmp logfile=imp_users.log
remap_schema=source_user:dest_user

Answer 2

简单答案：

创建导入：准备好转储。

还原转储的两个选项，考虑完整转储或特定表。

针对特定表：-表名称= MONTHS_DAY

impdp DBA_USER/DBA_Password tables = SOURCE_SCHEMA.MONTHS_DAY directory=AKSHAY_SPM_EDIR dumpfile=MONTHS_DAY.dmp logfile=impdpMONTHS_DAY.log remap_schema = SOURCE_SCHEMA:DESTINATION_SCHEMA

完整导入：

impdp DBA_USER/DBA_Password directory = AKSHAY_SPM_EDIR dumpfile=MONTHS_DAY.dmp logfile=impdpMONTHS_DAY.log remap_schema = SOURCE_SCHEMA:DESTINATION_SCHEMA

请确保目录可以访问，因为那里存在转储

oracle 11g impdp返回无效操作且未找到对象
