How to move table from one tablespace to another in oracle 11g - oracle

Question

I run oracle 11g and need to move table (tbl1) from one tablespace (tblspc1) to another (tblspc2). What is the easiest way to do that?

Answer 1

Try this:-
ALTER TABLE <TABLE NAME to be moved> MOVE TABLESPACE <destination TABLESPACE NAME>
Very nice suggestion from IVAN in comments so thought to add in my answer
Note: this will invalidate all table's indexes. So this command is usually followed by
alter index <owner>."<index_name>" rebuild;

Answer 2

Use sql from sql:
spool output of this to a file:
select 'alter index '||owner||'.'||index_name||' rebuild tablespace TO_TABLESPACE_NAME;' from all_indexes where owner='OWNERNAME';
spoolfile will have something like this:
alter index OWNER.PK_INDEX rebuild tablespace CORRECT_TS_NAME;

Moving tables:
First run:
SELECT 'ALTER TABLE <schema_name>.' || OBJECT_NAME ||' MOVE TABLESPACE '||' <tablespace_name>; '
FROM ALL_OBJECTS
WHERE OWNER = '<schema_name>'
AND OBJECT_TYPE = 'TABLE' <> '<TABLESPACE_NAME>';
-- Or suggested in the comments (did not test it myself)
SELECT 'ALTER TABLE <SCHEMA>.' || TABLE_NAME ||' MOVE TABLESPACE '||' TABLESPACE_NAME>; '
FROM dba_tables
WHERE OWNER = '<SCHEMA>'
AND TABLESPACE_NAME <> '<TABLESPACE_NAME>
Where <schema_name> is the name of the user.
And <tablespace_name> is the destination tablespace.
As a result you get lines like:
ALTER TABLE SCOT.PARTS MOVE TABLESPACE USERS;
Paste the results in a script or in a oracle sql developer like application and run it.
Moving indexes:
First run:
SELECT 'ALTER INDEX <schema_name>.'||INDEX_NAME||' REBUILD TABLESPACE <tablespace_name>;'
FROM ALL_INDEXES
WHERE OWNER = '<schema_name>'
AND TABLESPACE_NAME NOT LIKE '<tablespace_name>';
The last line in this code could save you a lot of time because it filters out the indexes which are already in the correct tablespace.
As a result you should get something like:
ALTER INDEX SCOT.PARTS_NO_PK REBUILD TABLESPACE USERS;
Paste the results in a script or in a oracle sql developer like application and run it.
Last but not least, moving LOBs:
First run:
SELECT 'ALTER TABLE <schema_name>.'||LOWER(TABLE_NAME)||' MOVE LOB('||LOWER(COLUMN_NAME)||') STORE AS (TABLESPACE <table_space>);'
FROM DBA_TAB_COLS
WHERE OWNER = '<schema_name>' AND DATA_TYPE like '%LOB%';
This moves the LOB objects to the other tablespace.
As a result you should get something like:
ALTER TABLE SCOT.bin$6t926o3phqjgqkjabaetqg==$0 MOVE LOB(calendar) STORE AS (TABLESPACE USERS);
Paste the results in a script or in a oracle sql developer like application and run it.
O and there is one more thing:
For some reason I wasn't able to move 'DOMAIN' type indexes. As a work around I dropped the index. changed the default tablespace of the user into de desired tablespace. and then recreate the index again.
There is propably a better way but it worked for me.

Answer 4

Try this to move your table (tbl1) to tablespace (tblspc2).
alter table tb11 move tablespace tblspc2;

Answer 5

I tried many scripts but they didn't work for all objects. You can't move clustered objects from one tablespace to another. For that you will have to use expdp, so I will suggest expdp is the best option to move all objects to a different tablespace.
Below is the command:
nohup expdp \"/ as sysdba\" DIRECTORY=test_dir DUMPFILE=users.dmp LOGFILE=users.log TABLESPACES=USERS &
