Merging partition into NEW partition

Question

I need to merge some range partition into a new big one,
something like
ALTER TABLE sales
MERGE PARTITIONS sales_q4_2000, sales_q4_2000b
INTO PARTITION sales_q4_2000;
My question is: How should I specify the tablespace for the NEW partition name ?
The following is my table definition:
CREATE TABLE "TEST"
(     "DAILY" DATE,
     "ID_TEST" NUMBER
TABLESPACE "TBL_DEFAULT_SLIDE"
PARTITION BY RANGE ("DAILY")
(PARTITION "PART_PAST" VALUES LESS THAN (TO_DATE(' 2008-08-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_PAST_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_08_01" VALUES LESS THAN (TO_DATE(' 2008-08-02 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_08_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_08_16" VALUES LESS THAN (TO_DATE(' 2008-08-17 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_08_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_08_31" VALUES LESS THAN (TO_DATE(' 2008-09-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_08_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_09_01" VALUES LESS THAN (TO_DATE(' 2008-09-02 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_09_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_09_16" VALUES LESS THAN (TO_DATE(' 2008-09-17 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_09_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_09_30" VALUES LESS THAN (TO_DATE(' 2008-10-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_09_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_10_01" VALUES LESS THAN (TO_DATE(' 2008-10-02 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_10_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_10_16" VALUES LESS THAN (TO_DATE(' 2008-10-17 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_10_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_10_31" VALUES LESS THAN (TO_DATE(' 2008-11-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_10_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_11_01" VALUES LESS THAN (TO_DATE(' 2008-11-02 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_11_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_11_16" VALUES LESS THAN (TO_DATE(' 2008-11-17 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_11_SLIDE" NOCOMPRESS ,
PARTITION "PART_2008_11_30" VALUES LESS THAN (TO_DATE(' 2008-12-01 00:00:00', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN'))
TABLESPACE "PART_2008_11_SLIDE" NOCOMPRESS ,
PARTITION "PART_FUTURE" VALUES LESS THAN (MAXVALUE)
TABLESPACE "PART_FUTURE_SLIDE" NOCOMPRESS ) ;
I'm trying to execute (where PART_2008_08 is a new partition, never used or created, so with no tablespace)
ALTER TABLE TEST
MERGE PARTITIONS PART_2008_08_01, PART_2008_08_16, PART_2008_08_31
INTO PARTITION PART_2008_08 TABLESPACE PART_2008_08_SLIDED;
or
(in this example where I don't specify the tablespace and according to SQL Reference [merge_table_partitions|http://download.oracle.com/docs/cd/B19306_01/server.102/b14200/statements_3001.htm#i2114069] it should create the new partition whereas any attributes are inherited from table-level defaults so it should create the NEW partition on TABLESPACE "TBL_DEFAULT_SLIDE".)
ALTER TABLE TEST
MERGE PARTITIONS PART_2008_08_01, PART_2008_08_16, PART_2008_08_31
INTO PARTITION PART_2008_08;
but both are failing with ORA-14126.
What am I missing ?

What am I missing ?I haven't tested your example but I think that you can merge only TWO partitions in one merge operation, so if you attempt to merge three partitions you need actually to perform this in two steps rather than in a single step. In addition in case of range partitions these have to adjacent to be merged, but this seems to be the case in your example.
