ORA-01652: unable to extend temp segment by 128 in tablespace TEMP2

hi experts,

when i  run the below query it gives the error:

select operation,status,start_time,end_time from v$rman_status order by start_time;

error--

ORA-01652: unable to extend temp segment by 128 in tablespace TEMP2;

my current tablespace size is:

SQL> select TABLESPACE_NAME, BYTES_USED, BYTES_FREE from V$TEMP_SPACE_HEADER;

TABLESPACE_NAME                BYTES_USED BYTES_FREE

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

TEMP1                          2147483648          0

TEMP1                           215220224 1.0522E+10

TEMP2                          2147483648          0

TEMP2                          2147483648          0

TEMP2                          4294967296          0
