Since the release of Oracle 10g and 9i, most would think that the need for scripts to recreate individual database components are unnecessary and they would be correct if you are already at Oracle 9i or 10g. Oracle 9i provides the user of the DBMS_METADATA package, which give the DBA the ability to generate the DDL for most any Oracle structure. Oracle 10g has enhanced the abilities of DBMS_METADATA and given the add value of ORACLE expdmp and impdmp, which do not require the existence of such objects as a user to transport data between databases. However, there still exist tons of Oracle 8i and earlier versions, which do not contain either of the abilities above and from which we still have to recreate individual oracle objects. This article is part of a series that covers the recreation of Oracle objects by producing the DDL from which to recreate them.
In this article we will cover the recreate of an Oracle User account in its most simple form. NOTE: We will not cover the recreation of a user defined profile or other objects an oracle user account may depend on. For that information, please see my related article Recreation of User defined Oracle Profiles.
The below script regenerates a user account:
set serveroutput on
spool c:\oradata\create_user_account.sql

curr varchar2(30):= ‘TEST_USER’;
v_ext varchar2(3);

for user in(select * from dba_users where username = curr)
loop
dbms_output.put_line(‘create tablespace ‘||user.default_tablespace);
for dat_file in(select * from dba_data_files where
tablespace_name=user.default_tablespace)
loop
if dat_file.autoextensible=’YES’
then
v_ext:=’ON’;
else
v_ext:=’OFF’;
end if;
