Yes, but in the "pre-historic" days, you couldn't create the rbs tablespace
without first creating
a non-system rollback segment in the system tablespace !

Subject: Re: A Simple Rollback Segment Question
Hi
AFAIK this is a prehistoric requirement (Pre 7.3 I believe, No offense
meant :-)). Oracle needed it to create the tablespaces etc. Since 7.3 this
is no longer required (anyone know exactly when?).
Personally I never create one. First thing I do though is create the rbs
tablespace with a couple of rollback seg's before all other create scripts.

Hello people,
This one is from Oracle Manual:
"In general, after database creation, you should create at least one
additional rollback segment in the SYSTEM tablespace. "
I can understand that you should create one additional rollback segment
after database creation b'coz otherwise oracle will use the SYSTEM rollback
segment and this may lead to fragmentation in the SYSTEM tablespace and
also a performance degradation. But why is one additional rollback segment
needed in SYSTEM TABLESPACE?
TIA
