Home -> Community -> Mailing Lists -> Oracle-L -> Re: A Simple Rollback Segment Question
Hi,
Correct.
It's just that I joined the Oracle Bandwagon when 7.3 was out already, so I never actually created an oracle pre 7.3 database.

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
