How to Move Tables into new tablespace of another Database


The case when you need to change tablespaces which is wrongly assigned and you want to move those users tables to different tablespace. First identify the tables from database which you want to move:

Select owner,table_name,tablespace_name from dba_tables where owner = 'ORAFIN';
OWNER TABLE_NAME  TABLESPACE_NAME
ORAFIN ACCFILE   MUJ_FIN_DBF
ORAFIN ACCOUNT_TRN           MUJ_FIN_DBF
ORAFIN ACCOUNT_TRN1         MUJ_FIN_DBF
ORAFIN APPLICATION  MUJ_FIN_DBF
ORAFIN ASSETS1   MUJ_FIN_DBF
ORAFIN ASSETS1_ALL  MUJ_FIN_DBF
ORAFIN ASSETS_ALL          MUJ_FIN_DBF
ORAFIN ASSETS_ALL_HI         MUJ_FIN_DBF
ORAFIN AUT_DISC          MUJ_FIN_DBF
ORAFIN AUT_LABEL          MUJ_FIN_DBF

Now you can use alter table command to move that tables to new tableapace. In the case while
moving the tables having index then you need to rebuild the index otherwise no need to do any thing.

Alter table table_name move tablespace KAF_ITGFIN_DBF;
Alter index <index_name> rebuild tablespace new_tablespace_name;

Generally Normal index moved explicitly where as LOB indexes are moved implicityly where as
related constraint will automatically moved to the new tablespace.

Now make sure the new schema is having the new default tablespace or not. Then the next time object is created on new tablespace.

Changing National Character Set AL16UTF16 to UTF8

Changing National Character Set AL16UTF16 to UTF8 The national character set is used for data that is stored in table columns of the types NCHAR, NVARCHAR2, and NCLOB.  In contrast, the database character set is used for data stored in table columns of the types CHAR, VARCHAR2 and CLOB. Like the database character set, the national character set is defined when the database is initially created and can usually no longer be changed, at least not easily or without involving quite a lot of work (export, recreate database, import). Except when creating the database, where the national character set is defined explicitly, it can change implicitly even when upgrading the database from Oracle8i to Oracle9i (or Oracle10g). You require SYSDBA authorization to change the national character set. Changing the national character set means changing an Oracle Dictionary entry, but no data is changed.  $sqlplus /nolog SQL> CONNECT / AS SYSDBA SQL> Select property_...
