问题现象是这样的，在IMP数据的过程中出现“IMP-00041:
Warning: object created with compilation warnings”错误，因这个错误导致视图导入后无法使用。经分析，发现此问题与“授权信息丢失”有关。
为避免朋友们走弯路，我模拟再现一下这个问题，同时给出一个分析和解决问题的思路。
1.创建两个用户sec1和sec2
sys@ora10g> create user sec1 identified by sec1 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec1;
Grant succeeded.
sys@ora10g> create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec2;
Grant succeeded.
2.在第一个用户sec1中创建表T_SEC1
sys@ora10g> conn sec1/sec1
Connected.
sec1@ora10g> create table t_sec1 (x int);
Table created.
sec1@ora10g> insert into t_sec1 values (1);
1 row created.
3.在第二个用户sec2中创建表T_SEC2
sec1@ora10g> conn sec2/sec2
Connected.
sec2@ora10g> create table t_sec2 (x int);
Table created.
sec2@ora10g> insert into t_sec2 values (2);
1 row created.
4.在sec2中创建sec1用户中t_sec1表的同名
sec2@ora10g> conn / as sysdba
Connected.
sys@ora10g> create synonym sec2.syn_t_sec1 for sec1.t_sec1;
Synonym created.
sys@ora10g> grant insert,delete,update,select on sec1.t_sec1 to sec2;
Grant succeeded.
5.在sec2用户下创建视图v_sec2
该视图同时使用到刚刚在sec2用户下创建的同名SYN_T_SEC1和表T_SEC2。
sec2@ora10g> conn / as sysdba
Connected.
sys@ora10g>
sys@ora10g> grant create view to sec2;
Grant succeeded.
sys@ora10g> conn sec2/sec2
Connected.
sec2@ora10g> create view v_sec2 as select SYN_T_SEC1.x sec1_x, T_SEC2.x sec2_x from SYN_T_SEC1,T_SEC2;
View created.
6.分别看一下各个用户下的数据库对象
sec2@ora10g> conn sec1/sec1
Connected.
sec1@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
T_SEC1 TABLE
sec2@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
T_SEC2 TABLE
SYN_T_SEC1 SYNONYM
V_SEC2 VIEW
7.我们这里分别生成sec1和sec2用户的备份

8.将备份文件发送到待导入的服务器secDB2
ora10g@secDB1 /exp$ scp sec1.dmp sec2.dmp 172.17.193.201:/imp
oracle@172.17.193.201's password:
sec1.dmp 100% 16KB 16.0KB/s 00:00
sec2.dmp 100% 16KB 16.0KB/s 00:00
9.在secDB2服务器上创建同样的用户，并进行导入测试
1）创建用户并授权
sys@ora10g> create user sec1 identified by sec1 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec1;
Grant succeeded.
sys@ora10g> create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource,dba to sec2;
Grant succeeded.
2）导入测试
（1）先导入sec1用户
ora10g@secDB2 /imp$ imp sec1/sec1 file=sec1.dmp log=sec1.log ignore=y full=y
Import: Release 10.2.0.3.0 - Production on Fri Feb 26 11:58:09 2010
Copyright (c) 1982, 2005, Oracle. All rights reserved.

import done in AL32UTF8 character set and UTF8 NCHAR character set
. importing SEC1's objects into SEC1
. . importing table "T_SEC1" 1 rows imported
Import terminated successfully without warnings.
（2）导入sec2用户
ora10g@secDB2
/imp$ imp sec2/sec2 file=sec2.dmp log=sec2.log ignore=y full=y
Import: Release 10.2.0.3.0 - Production on Fri Feb 26 21:14:59 2010

import done in AL32UTF8 character set and UTF8 NCHAR character set
. importing SEC2's objects into SEC2
. . importing table "T_SEC2" 1 rows imported
Import terminated successfully without warnings.
此时是导入成功的！演示还未结束，请继续。
（3）假如此时删除sec2用户（删除的目的可能有很多，比如之前授予的权限不足等），对其进行重新创建后再完成数据导入
sys@ora10g>
drop user sec2 cascade;
User dropped.
sys@ora10g>
create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g>
grant connect,resource,dba to sec2;
Grant succeeded.
（4）再重新完成sec2用户的IMP导入
ora10g@secDB2
/imp$ imp sec2/sec2 file=sec2.dmp log=sec2.log ignore=y full=y
Import: Release 10.2.0.3.0 - Production on Fri Feb 26 21:20:48 2010
Copyright (c) 1982, 2005, Oracle. All rights reserved.
Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.3.0 - 64bit Production

Export file created by EXPORT:V10.02.01 via conventional path
import done in AL32UTF8 character set and UTF8 NCHAR character set
. importing SEC2's objects into SEC2
. . importing table "T_SEC2" 1 rows imported
IMP-00041: Warning: object created with compilation warnings
"CREATE FORCE VIEW "SEC2"."V_SEC2" ("SEC1_X","SEC"
"2_X") AS "
"select SYN_T_SEC1.x sec1_x, T_SEC2.x sec2_x from SYN_T_SEC1,T_SEC2"
Import terminated successfully with warnings.
此时，问题出现了，此时的“IMP-00041”错误提示内容是创建的视图存在编译错误（这个错误没有太大的指导意义）。
10.验证被导入的内容是否可用
1）导入了三个对象，没有问题。
sec2@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
SYN_T_SEC1 SYNONYM
T_SEC2 TABLE
V_SEC2 VIEW
2）T_SEC2表可用
sec2@ora10g> select * from T_SEC2;
X
----------
2
3）SYN_T_SEC1同名可用
sec2@ora10g> select * from SYN_T_SEC1;
X
----------
1
4）此时视图不可用，提示存在错误。原因不详细。
sec2@ora10g> select * from V_SEC2;
select * from V_SEC2
*
ERROR at line 1:
ORA-04063: view "SEC2.V_SEC2" has errors
5）尝试重新编译，无效。
sec2@ora10g> alter view V_SEC2 compile;
Warning: View altered with compilation errors.
6）没有具体的错误提示信息
sec2@ora10g> show errors;
No errors.
11.问题原因
根本原因在于，当删除sec2用户重新创建后，sec2用户原来具有的sec1用户下T_SEC1表授权信息丢失了。
不要着急，我们来分析一下。
在完成sec1用户导入后，其实sec1用户的dmp文件中包含的授权信息已经完成对sec2用户的授权。我们使用“show=y”选项查看一下sec1用户的dmp文件内容。
ora10g@secDB2
/imp$ imp sec1/sec1 file=sec1.dmp log=sec1.log ignore=y full=y show=y

. . skipping table "T_SEC1"

"GRANT INSERT ON "T_SEC1" TO "SEC2""
"GRANT SELECT ON "T_SEC1" TO "SEC2""
"GRANT UPDATE ON "T_SEC1" TO "SEC2""
Import terminated successfully without warnings.
注意最后四行的授权信息。这些授权信息是在sec1用户数据导入过程中同时完成的。
12.问题处理
既然知道了问题的出处，处理就简单了。以sys用户显示的将sec1用户下t_sec1表的操作权限授予sec2用户，然后再重新对问题视图进行编译（当然，重新创建这个视图亦可）。
sec2@ora10g> conn / as sysdba
Connected.
sys@ora10g> grant insert,delete,update,select on sec1.t_sec1 to sec2;
Grant succeeded.
sys@ora10g> conn sec2/sec2
Connected.
sec2@ora10g> alter view V_SEC2 compile;
View altered.
sec2@ora10g> select * from V_SEC2;
SEC1_X SEC2_X
---------- ----------
1 2
1 row selected.
OK，问题到此处理完毕。
13.另外一种导致这个问题的场景演示
还用一种可能出现这种问题的可能性，如果是按照下面的顺序在secDB2服务器上完成用户的创建和导入，一样会报上面的错误。
创建sec1用户，完成对sec1用户的导入；
创建sec2用户，完成对sec2用户的导入。
因为在完成sec1用户导入后，授权信息的授予对象sec2还不存在！
为保证信息的完整性和正确性，赘述在此。
1）删除sec1和sec2用户
sys@ora10g>
drop user sec1 cascade;
User dropped.
sys@ora10g>
drop user sec2 cascade;
User dropped.
2）创建sec1用户，完成对sec1用户的导入
sys@ora10g>
create user sec1 identified by sec1 default tablespace TBS_SEC_D;
User created.
sys@ora10g>
grant connect,resource to sec1;
Grant succeeded.
sys@ora10g>
exit

问题又一次再现，错误原因与我们前面分析的结果相同。
14.小结
我们使用EXP/IMP工具在不同用户间存在较复杂的授权关系的情况下完成数据迁移时，需要特别注意他们的先后顺序。
为避免此类错误的发生，建议在多用户数据迁移场景下，使用sys用户一次性完成（使用OWNER参数）数据迁移工作。
问题现象是这样的，在IMP数据的过程中出现“IMP-00041:
Warning: object created with compilation warnings”错误，因这个错误导致视图导入后无法使用。经分析，发现此问题与“授权信息丢失”有关。
为避免朋友们走弯路，我模拟再现一下这个问题，同时给出一个分析和解决问题的思路。
1.创建两个用户sec1和sec2
sys@ora10g> create user sec1 identified by sec1 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec1;
Grant succeeded.
sys@ora10g> create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec2;
Grant succeeded.
2.在第一个用户sec1中创建表T_SEC1
sys@ora10g> conn sec1/sec1
Connected.
sec1@ora10g> create table t_sec1 (x int);
Table created.
sec1@ora10g> insert into t_sec1 values (1);
1 row created.
3.在第二个用户sec2中创建表T_SEC2
sec1@ora10g> conn sec2/sec2
Connected.
sec2@ora10g> create table t_sec2 (x int);
Table created.
sec2@ora10g> insert into t_sec2 values (2);
1 row created.
4.在sec2中创建sec1用户中t_sec1表的同名
sec2@ora10g> conn / as sysdba
Connected.
sys@ora10g> create synonym sec2.syn_t_sec1 for sec1.t_sec1;
Synonym created.
sys@ora10g> grant insert,delete,update,select on sec1.t_sec1 to sec2;
Grant succeeded.
5.在sec2用户下创建视图v_sec2
该视图同时使用到刚刚在sec2用户下创建的同名SYN_T_SEC1和表T_SEC2。
sec2@ora10g> conn / as sysdba
Connected.
sys@ora10g>
sys@ora10g> grant create view to sec2;
Grant succeeded.
sys@ora10g> conn sec2/sec2
Connected.
sec2@ora10g> create view v_sec2 as select SYN_T_SEC1.x sec1_x, T_SEC2.x sec2_x from SYN_T_SEC1,T_SEC2;
View created.
6.分别看一下各个用户下的数据库对象
sec2@ora10g> conn sec1/sec1
Connected.
sec1@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
T_SEC1 TABLE
sec2@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
T_SEC2 TABLE
SYN_T_SEC1 SYNONYM
V_SEC2 VIEW
7.我们这里分别生成sec1和sec2用户的备份

8.将备份文件发送到待导入的服务器secDB2
ora10g@secDB1 /exp$ scp sec1.dmp sec2.dmp 172.17.193.201:/imp
oracle@172.17.193.201's password:
sec1.dmp 100% 16KB 16.0KB/s 00:00
sec2.dmp 100% 16KB 16.0KB/s 00:00
9.在secDB2服务器上创建同样的用户，并进行导入测试
1）创建用户并授权
sys@ora10g> create user sec1 identified by sec1 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec1;
Grant succeeded.
sys@ora10g> create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource,dba to sec2;
Grant succeeded.
2）导入测试
（1）先导入sec1用户
ora10g@secDB2 /imp$ imp sec1/sec1 file=sec1.dmp log=sec1.log ignore=y full=y
Import: Release 10.2.0.3.0 - Production on Fri Feb 26 11:58:09 2010

import done in AL32UTF8 character set and UTF8 NCHAR character set
. importing SEC1's objects into SEC1
. . importing table "T_SEC1" 1 rows imported
Import terminated successfully without warnings.
（2）导入sec2用户
ora10g@secDB2
/imp$ imp sec2/sec2 file=sec2.dmp log=sec2.log ignore=y full=y
Import: Release 10.2.0.3.0 - Production on Fri Feb 26 21:14:59 2010

import done in AL32UTF8 character set and UTF8 NCHAR character set
. importing SEC2's objects into SEC2
. . importing table "T_SEC2" 1 rows imported
Import terminated successfully without warnings.
此时是导入成功的！演示还未结束，请继续。
（3）假如此时删除sec2用户（删除的目的可能有很多，比如之前授予的权限不足等），对其进行重新创建后再完成数据导入
sys@ora10g>
drop user sec2 cascade;
User dropped.
sys@ora10g>
create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g>
grant connect,resource,dba to sec2;
Grant succeeded.
（4）再重新完成sec2用户的IMP导入
ora10g@secDB2
/imp$ imp sec2/sec2 file=sec2.dmp log=sec2.log ignore=y full=y
Import: Release 10.2.0.3.0 - Production on Fri Feb 26 21:20:48 2010

. importing SEC2's objects into SEC2
. . importing table "T_SEC2" 1 rows imported
IMP-00041: Warning: object created with compilation warnings

"2_X") AS "
"select SYN_T_SEC1.x sec1_x, T_SEC2.x sec2_x from SYN_T_SEC1,T_SEC2"
Import terminated successfully with warnings.
此时，问题出现了，此时的“IMP-00041”错误提示内容是创建的视图存在编译错误（这个错误没有太大的指导意义）。
10.验证被导入的内容是否可用
1）导入了三个对象，没有问题。
sec2@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
SYN_T_SEC1 SYNONYM
T_SEC2 TABLE
V_SEC2 VIEW
2）T_SEC2表可用
sec2@ora10g> select * from T_SEC2;
X
----------
2
3）SYN_T_SEC1同名可用
sec2@ora10g> select * from SYN_T_SEC1;
X
----------
1
4）此时视图不可用，提示存在错误。原因不详细。
sec2@ora10g> select * from V_SEC2;
select * from V_SEC2
*
ERROR at line 1:
ORA-04063: view "SEC2.V_SEC2" has errors
5）尝试重新编译，无效。
sec2@ora10g> alter view V_SEC2 compile;
Warning: View altered with compilation errors.
6）没有具体的错误提示信息
sec2@ora10g> show errors;
No errors.
11.问题原因
根本原因在于，当删除sec2用户重新创建后，sec2用户原来具有的sec1用户下T_SEC1表授权信息丢失了。
不要着急，我们来分析一下。
在完成sec1用户导入后，其实sec1用户的dmp文件中包含的授权信息已经完成对sec2用户的授权。我们使用“show=y”选项查看一下sec1用户的dmp文件内容。
ora10g@secDB2
/imp$ imp sec1/sec1 file=sec1.dmp log=sec1.log ignore=y full=y show=y

"GRANT UPDATE ON "T_SEC1" TO "SEC2""
Import terminated successfully without warnings.
注意最后四行的授权信息。这些授权信息是在sec1用户数据导入过程中同时完成的。
12.问题处理
既然知道了问题的出处，处理就简单了。以sys用户显示的将sec1用户下t_sec1表的操作权限授予sec2用户，然后再重新对问题视图进行编译（当然，重新创建这个视图亦可）。
sec2@ora10g> conn / as sysdba
Connected.
sys@ora10g> grant insert,delete,update,select on sec1.t_sec1 to sec2;
Grant succeeded.
sys@ora10g> conn sec2/sec2
Connected.
sec2@ora10g> alter view V_SEC2 compile;
View altered.
sec2@ora10g> select * from V_SEC2;
SEC1_X SEC2_X
---------- ----------
1 2
1 row selected.
OK，问题到此处理完毕。
13.另外一种导致这个问题的场景演示
还用一种可能出现这种问题的可能性，如果是按照下面的顺序在secDB2服务器上完成用户的创建和导入，一样会报上面的错误。
创建sec1用户，完成对sec1用户的导入；
创建sec2用户，完成对sec2用户的导入。
因为在完成sec1用户导入后，授权信息的授予对象sec2还不存在！
为保证信息的完整性和正确性，赘述在此。
1）删除sec1和sec2用户
sys@ora10g>
drop user sec1 cascade;
User dropped.
sys@ora10g>
drop user sec2 cascade;
User dropped.
2）创建sec1用户，完成对sec1用户的导入
sys@ora10g>
create user sec1 identified by sec1 default tablespace TBS_SEC_D;
User created.
sys@ora10g>
grant connect,resource to sec1;
Grant succeeded.
sys@ora10g>
exit

问题又一次再现，错误原因与我们前面分析的结果相同。
14.小结
我们使用EXP/IMP工具在不同用户间存在较复杂的授权关系的情况下完成数据迁移时，需要特别注意他们的先后顺序。
为避免此类错误的发生，建议在多用户数据迁移场景下，使用sys用户一次性完成（使用OWNER参数）数据迁移工作。

问题现象是这样的，在IMP数据的过程中出现“IMP-00041:
Warning: object created with compilation warnings”错误，因这个错误导致视图导入后无法使用。经分析，发现此问题与“授权信息丢失”有关。
为避免朋友们走弯路，我模拟再现一下这个问题，同时给出一个分析和解决问题的思路。
1.创建两个用户sec1和sec2
sys@ora10g> create user sec1 identified by sec1 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec1;
Grant succeeded.
sys@ora10g> create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec2;
Grant succeeded.
2.在第一个用户sec1中创建表T_SEC1
sys@ora10g> conn sec1/sec1
Connected.
sec1@ora10g> create table t_sec1 (x int);
Table created.
sec1@ora10g> insert into t_sec1 values (1);
1 row created.
3.在第二个用户sec2中创建表T_SEC2
sec1@ora10g> conn sec2/sec2
Connected.
sec2@ora10g> create table t_sec2 (x int);
Table created.
sec2@ora10g> insert into t_sec2 values (2);
1 row created.
4.在sec2中创建sec1用户中t_sec1表的同名
sec2@ora10g> conn / as sysdba
Connected.
sys@ora10g> create synonym sec2.syn_t_sec1 for sec1.t_sec1;
Synonym created.
sys@ora10g> grant insert,delete,update,select on sec1.t_sec1 to sec2;
Grant succeeded.
5.在sec2用户下创建视图v_sec2
该视图同时使用到刚刚在sec2用户下创建的同名SYN_T_SEC1和表T_SEC2。
sec2@ora10g> conn / as sysdba
Connected.
sys@ora10g>
sys@ora10g> grant create view to sec2;
Grant succeeded.
sys@ora10g> conn sec2/sec2
Connected.
sec2@ora10g> create view v_sec2 as select SYN_T_SEC1.x sec1_x, T_SEC2.x sec2_x from SYN_T_SEC1,T_SEC2;
View created.
6.分别看一下各个用户下的数据库对象
sec2@ora10g> conn sec1/sec1
Connected.
sec1@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
T_SEC1 TABLE
sec2@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
T_SEC2 TABLE
SYN_T_SEC1 SYNONYM
V_SEC2 VIEW
7.我们这里分别生成sec1和sec2用户的备份

8.将备份文件发送到待导入的服务器secDB2
ora10g@secDB1 /exp$ scp sec1.dmp sec2.dmp 172.17.193.201:/imp
oracle@172.17.193.201's password:
sec1.dmp 100% 16KB 16.0KB/s 00:00
sec2.dmp 100% 16KB 16.0KB/s 00:00
9.在secDB2服务器上创建同样的用户，并进行导入测试
1）创建用户并授权
sys@ora10g> create user sec1 identified by sec1 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec1;
Grant succeeded.
sys@ora10g> create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource,dba to sec2;
Grant succeeded.
2）导入测试
（1）先导入sec1用户
ora10g@secDB2 /imp$ imp sec1/sec1 file=sec1.dmp log=sec1.log ignore=y full=y
Import: Release 10.2.0.3.0 - Production on Fri Feb 26 11:58:09 2010
Copyright (c) 1982, 2005, Oracle. All rights reserved.

import done in AL32UTF8 character set and UTF8 NCHAR character set
. importing SEC1's objects into SEC1
. . importing table "T_SEC1" 1 rows imported
Import terminated successfully without warnings.
（2）导入sec2用户
ora10g@secDB2
/imp$ imp sec2/sec2 file=sec2.dmp log=sec2.log ignore=y full=y
Import: Release 10.2.0.3.0 - Production on Fri Feb 26 21:14:59 2010

import done in AL32UTF8 character set and UTF8 NCHAR character set
. importing SEC2's objects into SEC2
. . importing table "T_SEC2" 1 rows imported
Import terminated successfully without warnings.
此时是导入成功的！演示还未结束，请继续。
（3）假如此时删除sec2用户（删除的目的可能有很多，比如之前授予的权限不足等），对其进行重新创建后再完成数据导入
sys@ora10g>
drop user sec2 cascade;
User dropped.
sys@ora10g>
create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g>
grant connect,resource,dba to sec2;
Grant succeeded.
（4）再重新完成sec2用户的IMP导入
ora10g@secDB2
/imp$ imp sec2/sec2 file=sec2.dmp log=sec2.log ignore=y full=y
Import: Release 10.2.0.3.0 - Production on Fri Feb 26 21:20:48 2010

. importing SEC2's objects into SEC2
. . importing table "T_SEC2" 1 rows imported
IMP-00041: Warning: object created with compilation warnings

"2_X") AS "
"select SYN_T_SEC1.x sec1_x, T_SEC2.x sec2_x from SYN_T_SEC1,T_SEC2"
Import terminated successfully with warnings.
此时，问题出现了，此时的“IMP-00041”错误提示内容是创建的视图存在编译错误（这个错误没有太大的指导意义）。
10.验证被导入的内容是否可用
1）导入了三个对象，没有问题。
sec2@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
SYN_T_SEC1 SYNONYM
T_SEC2 TABLE
V_SEC2 VIEW
2）T_SEC2表可用
sec2@ora10g> select * from T_SEC2;
X
----------
2
3）SYN_T_SEC1同名可用
sec2@ora10g> select * from SYN_T_SEC1;
X
----------
1
4）此时视图不可用，提示存在错误。原因不详细。
sec2@ora10g> select * from V_SEC2;
select * from V_SEC2
*
ERROR at line 1:
ORA-04063: view "SEC2.V_SEC2" has errors
5）尝试重新编译，无效。
sec2@ora10g> alter view V_SEC2 compile;
Warning: View altered with compilation errors.
6）没有具体的错误提示信息
sec2@ora10g> show errors;
No errors.
11.问题原因
根本原因在于，当删除sec2用户重新创建后，sec2用户原来具有的sec1用户下T_SEC1表授权信息丢失了。
不要着急，我们来分析一下。
在完成sec1用户导入后，其实sec1用户的dmp文件中包含的授权信息已经完成对sec2用户的授权。我们使用“show=y”选项查看一下sec1用户的dmp文件内容。
ora10g@secDB2
/imp$ imp sec1/sec1 file=sec1.dmp log=sec1.log ignore=y full=y show=y

"GRANT UPDATE ON "T_SEC1" TO "SEC2""
Import terminated successfully without warnings.
注意最后四行的授权信息。这些授权信息是在sec1用户数据导入过程中同时完成的。
12.问题处理
既然知道了问题的出处，处理就简单了。以sys用户显示的将sec1用户下t_sec1表的操作权限授予sec2用户，然后再重新对问题视图进行编译（当然，重新创建这个视图亦可）。
sec2@ora10g> conn / as sysdba
Connected.
sys@ora10g> grant insert,delete,update,select on sec1.t_sec1 to sec2;
Grant succeeded.
sys@ora10g> conn sec2/sec2
Connected.
sec2@ora10g> alter view V_SEC2 compile;
View altered.
sec2@ora10g> select * from V_SEC2;
SEC1_X SEC2_X
---------- ----------
1 2
1 row selected.
OK，问题到此处理完毕。
13.另外一种导致这个问题的场景演示
还用一种可能出现这种问题的可能性，如果是按照下面的顺序在secDB2服务器上完成用户的创建和导入，一样会报上面的错误。
创建sec1用户，完成对sec1用户的导入；
创建sec2用户，完成对sec2用户的导入。
因为在完成sec1用户导入后，授权信息的授予对象sec2还不存在！
为保证信息的完整性和正确性，赘述在此。
1）删除sec1和sec2用户
sys@ora10g>
drop user sec1 cascade;
User dropped.
sys@ora10g>
drop user sec2 cascade;
User dropped.
2）创建sec1用户，完成对sec1用户的导入
sys@ora10g>

Import terminated successfully with warnings.
问题又一次再现，错误原因与我们前面分析的结果相同。
14.小结
我们使用EXP/IMP工具在不同用户间存在较复杂的授权关系的情况下完成数据迁移时，需要特别注意他们的先后顺序。
为避免此类错误的发生，建议在多用户数据迁移场景下，使用sys用户一次性完成（使用OWNER参数）数据迁移工作。
问题现象是这样的，在IMP数据的过程中出现“IMP-00041:
Warning: object created with compilation warnings”错误，因这个错误导致视图导入后无法使用。经分析，发现此问题与“授权信息丢失”有关。
为避免朋友们走弯路，我模拟再现一下这个问题，同时给出一个分析和解决问题的思路。
1.创建两个用户sec1和sec2
sys@ora10g> create user sec1 identified by sec1 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec1;
Grant succeeded.
sys@ora10g> create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec2;
Grant succeeded.
2.在第一个用户sec1中创建表T_SEC1
sys@ora10g> conn sec1/sec1
Connected.
sec1@ora10g> create table t_sec1 (x int);
Table created.
sec1@ora10g> insert into t_sec1 values (1);
1 row created.
3.在第二个用户sec2中创建表T_SEC2
sec1@ora10g> conn sec2/sec2
Connected.
sec2@ora10g> create table t_sec2 (x int);
Table created.
sec2@ora10g> insert into t_sec2 values (2);
1 row created.
4.在sec2中创建sec1用户中t_sec1表的同名
sec2@ora10g> conn / as sysdba
Connected.
sys@ora10g> create synonym sec2.syn_t_sec1 for sec1.t_sec1;
Synonym created.
sys@ora10g> grant insert,delete,update,select on sec1.t_sec1 to sec2;
Grant succeeded.
5.在sec2用户下创建视图v_sec2
该视图同时使用到刚刚在sec2用户下创建的同名SYN_T_SEC1和表T_SEC2。
sec2@ora10g> conn / as sysdba
Connected.
sys@ora10g>
sys@ora10g> grant create view to sec2;
Grant succeeded.
sys@ora10g> conn sec2/sec2
Connected.
sec2@ora10g> create view v_sec2 as select SYN_T_SEC1.x sec1_x, T_SEC2.x sec2_x from SYN_T_SEC1,T_SEC2;
View created.
6.分别看一下各个用户下的数据库对象
sec2@ora10g> conn sec1/sec1
Connected.
sec1@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
T_SEC1 TABLE
sec2@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
T_SEC2 TABLE
SYN_T_SEC1 SYNONYM
V_SEC2 VIEW
7.我们这里分别生成sec1和sec2用户的备份

8.将备份文件发送到待导入的服务器secDB2
ora10g@secDB1 /exp$ scp sec1.dmp sec2.dmp 172.17.193.201:/imp
oracle@172.17.193.201's password:
sec1.dmp 100% 16KB 16.0KB/s 00:00
sec2.dmp 100% 16KB 16.0KB/s 00:00
9.在secDB2服务器上创建同样的用户，并进行导入测试
1）创建用户并授权
sys@ora10g> create user sec1 identified by sec1 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource to sec1;
Grant succeeded.
sys@ora10g> create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g> grant connect,resource,dba to sec2;
Grant succeeded.
2）导入测试
（1）先导入sec1用户
ora10g@secDB2 /imp$ imp sec1/sec1 file=sec1.dmp log=sec1.log ignore=y full=y

. importing SEC2's objects into SEC2
. . importing table "T_SEC2" 1 rows imported
Import terminated successfully without warnings.
此时是导入成功的！演示还未结束，请继续。
（3）假如此时删除sec2用户（删除的目的可能有很多，比如之前授予的权限不足等），对其进行重新创建后再完成数据导入
sys@ora10g>
drop user sec2 cascade;
User dropped.
sys@ora10g>
create user sec2 identified by sec2 default tablespace TBS_SEC_D;
User created.
sys@ora10g>
grant connect,resource,dba to sec2;
Grant succeeded.
（4）再重新完成sec2用户的IMP导入
ora10g@secDB2
/imp$ imp sec2/sec2 file=sec2.dmp log=sec2.log ignore=y full=y

Import terminated successfully with warnings.
此时，问题出现了，此时的“IMP-00041”错误提示内容是创建的视图存在编译错误（这个错误没有太大的指导意义）。
10.验证被导入的内容是否可用
1）导入了三个对象，没有问题。
sec2@ora10g> select * from cat;
TABLE_NAME TABLE_TYPE
------------------------------ -----------
SYN_T_SEC1 SYNONYM
T_SEC2 TABLE
V_SEC2 VIEW
2）T_SEC2表可用

X
----------
2
3）SYN_T_SEC1同名可用
sec2@ora10g> select * from SYN_T_SEC1;
X
----------
1
4）此时视图不可用，提示存在错误。原因不详细。
sec2@ora10g> select * from V_SEC2;
select * from V_SEC2
*
ERROR at line 1:

5）尝试重新编译，无效。
sec2@ora10g> alter view V_SEC2 compile;
Warning: View altered with compilation errors.
6）没有具体的错误提示信息
sec2@ora10g> show errors;
No errors.
11.问题原因
根本原因在于，当删除sec2用户重新创建后，sec2用户原来具有的sec1用户下T_SEC1表授权信息丢失了。
不要着急，我们来分析一下。
在完成sec1用户导入后，其实sec1用户的dmp文件中包含的授权信息已经完成对sec2用户的授权。我们使用“show=y”选项查看一下sec1用户的dmp文件内容。

问题又一次再现，错误原因与我们前面分析的结果相同。
14.小结
我们使用EXP/IMP工具在不同用户间存在较复杂的授权关系的情况下完成数据迁移时，需要特别注意他们的先后顺序。
为避免此类错误的发生，建议在多用户数据迁移场景下，使用sys用户一次性完成（使用OWNER参数）数据迁移工作。
