How to Move LOBSEGMENT LOBINDEX to Another Tablespace

Check LOB current tablespace

SQL> select owner, segment_name, segment_type, tablespace_name , bytes from dba_segments where owner='USER1';

OWNER    SEGMENT_NAME                SEGMENT_TYPE       TABLESPACE_NAME    BYTES
-------- --------------------------- ------------------ ----------------- ----------
USER1    SYS_IL0000057639C00010$$    LOBINDEX           TEMPDATA	       65536
USER1    SYS_LOB0000057639C00010$$   LOBSEGMENT         TEMPDATA	    12713984
USER1    SYS_IL0000057685C00008$$    LOBINDEX           TEMPDATA	       65536

Generate moving LObs sql 

SQL> select 'alter table  '||owner||'.'||table_name||' move lob ('||column_name||') store as (tablespace USER1) ;' from dba_lobs where  owner='USER1';

'ALTERTABLE'||OWNER||'.'||TABLE_NAME||'MOVELOB('||COLUMN_NAME||')STOREAS(TABLESPACE USER1;'
---------------------------------------------------------------------------------------------
alter table  USER1.TABLE1 move lob (DATA) store as (tablespace USER1);
alter table  USER1.TABLE2 move lob (DATA) store as (tablespace USER1);
alter table  USER1.TABLE3 move lob (DATA) store as (tablespace USER1);

move lobs into new tablespace

SQL>alter table  USER1.TABLE1 move lob (DATA) store as (tablespace USER1);
Table altered.

SQL>alter table  USER1.TABLE2 move lob (DATA) store as (tablespace USER1);
Table altered.

SQL>alter table  USER1.TABLE3 move lob (DATA) store as (tablespace USER1);
Table altered.

check lobs moved into new tablespace

SQL> select owner, segment_name, segment_type, tablespace_name , bytes from dba_segments where owner='USER1';

OWNER    SEGMENT_NAME                SEGMENT_TYPE       TABLESPACE_NAME    BYTES
-------- --------------------------- ------------------ ----------------- ----------

rebuild UNUSABLE indxes

SQL>  select 'alter index '||owner||'.'||INDEX_NAME||' rebuild;' from dba_indexes where owner='USER1' and STATUS='UNUSABLE';

'ALTERINDEX'||OWNER||'.'||INDEX_NAME||'REBUILD;'
------------------------------------------------------
alter index USER1.idx_customers rebuild;
alter index USER1.idx_prods rebuild;
alter index USER1.idx_orders rebuild;
....
..
.

SQL>alter index USER1.idx_customers rebuild;
Index altered.

SQL>alter index USER1.idx_prods rebuild;
Index altered.

SQL>alter index USER1.idx_orders rebuild;
Index altered.

Please note LOBINDEX will be automatically relocated onto the same new tablespace as LOBSEGMENT, so there is no need to run SQL to relocate LOBINDEX . Otherwise the error will occur.
