如何在enable了database vault的数据库里运行datapump
2024-06-13 17:23:06
我们用datapump_test这个用户来进行datapump的导出工作，需要对这个用户赋予一些权限
00:38:25 SQL> create user datapump_test identified by datapump_test;User created.Elapsed: 00:00:00.0900:39:52 SQL> grant connect,unlimited tablespace to datapump_test;Grant succeeded.Elapsed: 00:00:00.0100:40:55 SQL> grant datapump_imp_full_database,datapump_exp_full_database to datapump_test;Grant succeeded.Elapsed: 00:00:00.01因为是在vault的环境下，所以需要做以下的赋权操作
00:42:49 SQL> grant become user to datapump_test;Grant succeeded.00:43:31 SQL> exec dbms_macadm.authorize_datapump_user(uname=>'datapump_test');PL/SQL procedure successfully completed.Elapsed: 00:00:00.01如果要导出整个数据库，则还需要赋予dv_owner 这个role
00:44:31 SQL> grant dv_owner to datapump_test;Grant succeeded.Elapsed: 00:00:00.00
导出数据库
[oracle@scaqai06adm07 bin]$ expdp datapump_test/datapump_test@comp1pdb21048 directory=data_pump_dir dumpfile=comp1pdb21048_20201111_1646.dmp full=yes
00:50:25 SQL> create user impdp_test identified by impdp_test;User created.Elapsed: 00:00:00.37
00:50:44 SQL> grant connect,unlimited tablespace to impdp_test;Grant succeeded.Elapsed: 00:00:00.05
00:50:58 SQL> grant datapump_exp_full_database,datapump_imp_full_database to impdp_test;Grant succeeded.Elapsed: 00:00:00.0200:51:22 SQL> grant become user to impdp_test;Grant succeeded.Elapsed: 00:00:00.01
00:52:06 SQL> grant dv_owner to impdp_test;Grant succeeded.Elapsed: 00:00:00.0101:01:09 SQL> exec dbms_macadm.authorize_datapump_user(uname=>'IMPDP_TEST');PL/SQL procedure successfully completed.
碰到这个错误的原因是因为通过connect string连到了另外一个instance上，而data_pump_dir那个目录不是shared，在另外一个instance上找不到

ORA-01950: no privileges on tablespace ‘SYSTEM’
上面这个错误的原因是本来u100在源数据库是有在system表空间写入数据的权限，结果在写入数据后，将这个权限又revoke掉了，所以在impdp的时候，u100就没有权限写入system表空间了，所以就报错了
解决方法就是在source db，对u100赋予unlimited tablespace权限，然后重新导出，再导入就没有这个错误了
这是最后一次执行，还是有不少的错误
