Tablespace resize

Question

Using a Bigfile tablespace (maxsize 250G) in Oracle 10g on Solaris.
In bigfile tablespace I cannot add a second datafile like normal tablespace.
Want to know when the tablespace reaches the maxsize 250G, what options do I have?
Can I increase the maxsize ?
If I re-size the datafile will it tamper the data in any way?

Hi Teymur,
You mean to say that I have only the option to resize everytime the tablespace reaches the upper boundary.
Its a index tablespace, does resizing tamper in any way the index structure or data ?
Why isn't the maxsize pushed up when I resize the datafile ?Pls, see:
SQL> create bigfile tablespace big_ts datafile '/oradata/db1/big_ts_1.dbf' size 10 m autoextend on next 1m maxsize 20m;
Tablespace created.
SQL> create table big_ts_obj tablespace big_ts as select * from dba_objects;
Table created.
SQL> insert into big_ts_obj select * from big_ts_obj;
69489 rows created.
SQL> /
insert into big_ts_obj select * from big_ts_obj
ERROR at line 1:
ORA-01653: unable to extend table SYS.BIG_TS_OBJ by 128 in tablespace BIG_TS
SQL> alter database datafile '/oradata/db1/big_ts_1.dbf' autoextend on next 1m maxsize unlimited

There is no any relationship between size of datafiles (or resizing datafiles) and INDEX structure.
