Tablespaces DDL - Oracle


There may be situation where you are trying to create a new database similar to old one and it is a fresh install and you need to get the Tablespaces DDL from the old one. This query will be very help full.

SQL>Set pages 999;
SQL>set long 90000;
SQL>spool ddl_list.sql

SQL>select dbms_metadata.get_ddl('TABLESPACE',tb.tablespace_name) from dba_tablespaces tb;

SQL>spool off
