The SYSTEM rollback segment is/was created initially on a database build,
and the recommendation has always been to add extra rollback segments
straight away for normal transactional processing. You really *should* have
other rollback segments available for your users.. What output do you get
from the following SQL:
select segment_name, status from dba_rollback_segs;
To further answer your question the statement should be:
alter rollback segment system storage (maxextents 1024);
Note: you don't have to qualify that it's "sys.system"..
And to forestall you should you get a further error (ORA-02226: invalid
MAXEXTENTS value (max allowed: 505)):
alter rollback segment system storage (maxextents 505);

Mark,
Thanks, your command doesn't help. To answer your question, Database was
setup'd by previous DBA. Still i've never seen this type of segment...
SQL> alter rollback SEGMENT sys.system storage (maxextents 1024);
alter rollback SEGMENT sys.system storage (maxextents 1024)
*
ERROR at line 1:
ORA-02244: invalid ALTER ROLLBACK SEGMENT option

Do you mind if I ask why? Do you have any other rollback segments in place
other than the SYSTEM one?
In answer to your question though, look at the error message.. You missed
out the word "segment".
alter rollback SEGMENT sys.system storage (maxextents 1024);
