I am trying to export a schema/user in Oracle with its roles and system privileges. I don't want to export any data or any table. I have tried to export users using the following command.
expdp system/system@gisdblocal include=user DIRECTORY = TestBack
logfile=test12.log DUMPFILE=test12.dmp SCHEMAS=test_replication
When I import this in other database or in the same database with a different name i.e
impdp system/system@gisdblocal DIRECTORY = TestBack DUMPFILE = test12.dmp
SCHEMAS = test_replication REMAP_SCHEMA =
test_replication:test_replication_copy
the user or schema is created but it has not been granted any role or system privileges.
I am doing this because I have created a backup of a schema using the user that did not have the required rights DATAPUMP_IMP_FULL_DATABASE or DATAPUMP_EXP_FULL_DATABASE. When I restore that backup in another database, it says the user does not exist. Therefore, I am thinking to create a user with the same privileges first and then restore the backup.
Using SQL...
SELECT dbms_metadata.get_ddl('USER', :name)
FROM dual
UNION ALL
SELECT dbms_metadata.get_granted_ddl('ROLE_GRANT', grantee)
FROM dba_role_privs
WHERE grantee = :name
AND ROWNUM = 1
UNION ALL
SELECT dbms_metadata.get_granted_ddl('DEFAULT_ROLE', grantee)
FROM dba_role_privs
WHERE grantee = :name
AND ROWNUM = 1
UNION ALL
SELECT dbms_metadata.get_granted_ddl('SYSTEM_GRANT', grantee)
FROM dba_sys_privs sp,
system_privilege_map spm
WHERE sp.grantee = :name
AND sp.privilege = spm.name
AND spm.property <> 1
AND ROWNUM = 1
UNION ALL
SELECT dbms_metadata.get_granted_ddl('OBJECT_GRANT', grantee)
FROM dba_tab_privs
WHERE grantee = :name
AND ROWNUM = 1
UNION ALL
SELECT dbms_metadata.get_granted_ddl('TABLESPACE_QUOTA', username)
FROM dba_ts_quotas
WHERE username = :name
AND ROWNUM = 1
:name being...a bind variable for the USER you want to re-create.
