实验环境：REDHAT 5.5 X64系统+ORACLE10.2.0.4

实验要求：将表迁移至其他表空间

实验过程

建立源表空间及用户

create tablespace test1 datafile '/home/oracle/oradata/orcl/test101.dat'

size 100m;

create tablespace test2 datafile '/home/oracle/oradata/orcl/test102.dat'

size 100m;

create user test identified

by test default tablespace test1 temporary tablespace temp;

grant

resource,connect,dba to test;

create table test.testtp

as (select * from dba_object_tables);

create table

test.testtp1 as (select * from dba_object_tables);

create table

test.testtp2 as (select * from dba_object_tables);

create table

test.testtp3 as (select * from dba_object_tables);

conn test/test

create index

testtpi on ttesttp(table_name) tablespace test1;

create index

testtp1i on testtp1(table_name) tablespace test1;

create index

testtp2i on testtp2(table_name) tablespace test1;

create index

testtp3i on testtp3(table_name) tablespace test1;

1.查询当前表空间所包含表

select

table_name ,tablespace_name from dba_tables where tablespace_name = 'TEST1';

2.查询当前用户默认表空间

select

username,default_tablespace from dba_users where username = 'TEST';

3.查询TEST用户下的需要表分析的表并生成表分析语句

注：可能出现回车符号，去掉使得语句为一行，即可执行

SQL> select

'exec dbms_stats.gather_table_stats(ownname=> '|| '''' || owner || ''''||

',tabname=>' ||''''|| table_name ||

''''||',cascade=>true);'  from

all_all_tables  where owner in ('TEST');

'EXECDBMS_STATS.GATHER_TABLE_STATS(OWNNAME=>'||''''||OWNER||''''||',TABNAME=>'||

--------------------------------------------------------------------------------

exec

dbms_stats.gather_table_stats(ownname=>

'TEST',tabname=>'TESTTP3',cascade=>true);

exec

dbms_stats.gather_table_stats(ownname=>

'TEST',tabname=>'TESTTP2',cascade=>true);

exec

dbms_stats.gather_table_stats(ownname=>

'TEST',tabname=>'TESTTP1',cascade=>true);

exec

dbms_stats.gather_table_stats(ownname=>

'TEST',tabname=>'TESTTP',cascade=>true);

'EXECDBMS_STATS.GATHER_TABLE_STATS(OWNNAME=>'||''''||OWNER||''''||',TABNAME=>'||

SQL> exec

dbms_stats.gather_table_stats(ownname=>

'TEST',tabname=>'TESTTP3',cascade=>true);

PL/SQL procedure

successfully completed.

SQL> exec

dbms_stats.gather_table_stats(ownname=>

'TEST',tabname=>'TESTTP2',cascade=>true);

PL/SQL procedure

successfully completed.

SQL> exec

dbms_stats.gather_table_stats(ownname=>

'TEST',tabname=>'TESTTP1',cascade=>true);

PL/SQL procedure

successfully completed.

SQL> exec

dbms_stats.gather_table_stats(ownname=>

'TEST',tabname=>'TESTTP',cascade=>true);

PL/SQL procedure

successfully completed.

3.查看用户下所有索引状态

SQL> select

index_name,tablespace_name,status from all_indexes where wner= 'TEST';

INDEX_NAME

------------------------------

TABLESPACE_NAME

STATUS

------------------------------------------------------------

--------

TESTTP3I

TEST1

VALID

TESTTP2I

TEST1

VALID

TESTTP1I

TEST1

VALID

4.将表迁移到新表空间中

conn

test/test

alter

table testtp move tablespace TEST2;

alter

table testtp1 move tablespace TEST2;

alter

table testtp2 move tablespace TEST2;

alter

table testtp3 move tablespace TEST2;

5.表迁移完成之后查看当前表空间和原表空间的表

SQL>

select table_name ,tablespace_name from dba_tables where tablespace_name =

'TEST1';

no

rows selected

SQL>

select table_name ,tablespace_name from dba_tables where tablespace_name =

'TEST2';

TABLE_NAME                     TABLESPACE_NAME

------------------------------

------------------------------

TESTTP                         TEST2

TESTTP1                        TEST2

TESTTP2                        TEST2

TESTTP3                        TEST2

6.查看用户下所有索引状态

SQL> select

index_name,tablespace_name,status from all_indexes where wner= 'TEST';

INDEX_NAME

------------------------------

TABLESPACE_NAME

STATUS

------------------------------------------------------------

--------

TESTTP3I

TEST1

UNUSABLE

TESTTP2I

TEST1

UNUSABLE

TESTTP1I

TEST1

UNUSABLE

7.重建索引

生成重建索引语句

SQL> Select  distinct

'alter index

'||b.owner||'.'||b.index_name||' rebuild online tablespace

'||tablespace_name||';' from dba_ind_columns a, dba_indexes b where

a.table_owner = b.owner and b.owner = 'TEST' and a.table_name in(select table_name

from all_indexes where wner= 'TEST' and STATUS='UNUSABLE') And  a.index_name = b.index_name;

'ALTERINDEX'||B.OWNER||'.'||B.INDEX_NAME||'REBUILDONLINETABLESPACE'||TABLESPACE_

--------------------------------------------------------------------------------

alter index

TEST.TESTTP2I rebuild online tablespace TEST1;

alter index

TEST.TESTTP1I rebuild online tablespace TEST1;

alter index

TEST.TESTTP3I rebuild online tablespace TEST1;

8.查看用户下所有索引状态

SQL> select

index_name,tablespace_name,status from all_indexes where wner= 'TEST';

SQL> select

index_name,tablespace_name,status from all_indexes where wner= 'TEST';

INDEX_NAME

------------------------------

TABLESPACE_NAME                                              STATUS

------------------------------------------------------------

--------

TESTTP3I

TEST1

VALID

TESTTP1I

TEST1

VALID

TESTTP2I

TEST1

VALID

9.重新进行表分析

略
