Home -> Community -> Mailing Lists -> Oracle-L -> RE: RBS in SYSTEM Ts
Now its clear to me, maybe I should apply a RTFM to myself.
Thanks for the help.

If this UNDO ts name matches the name in initSId.ora=20
undo_tablespace=3Dyour_undo_ts_name
then it should be all set.=20
BTW, here is what I have from my 9i test db:
SQL> select segment_name,owner from dba_rollback_segs;
=20
SEGMENT_NAME OWNER ------------------------------ ------ SYSTEM SYS _SYSSMU1$ PUBLIC _SYSSMU2$ PUBLIC _SYSSMU3$ PUBLIC _SYSSMU4$ PUBLIC _SYSSMU5$ PUBLIC _SYSSMU6$ PUBLIC _SYSSMU7$ PUBLIC _SYSSMU8$ PUBLIC _SYSSMU9$ PUBLIC _SYSSMU10$ PUBLIC

ok, I didn't see the complete scenary, there's an UNDO ts created, in =
=3D
that case all the undo operations are redirected to this TS? If so then, =
=3D
the rbs created on SYSTEM ts is just ignored? or is still a possible =3D
issue and would be better to remove it?

Gabriel:
You are absolutely right. You can ask the DB owner to read some basic =

oracle
docs.

Hello list, I just found in the DB that the only RBS created is using =
=3D
=3D3D
the SYSTEM ts, I want to suggest the DB owner to create another TS for =
=3D
=3D3D
RBS operations with 3 or 4 RBS, and not use the SYSTEM ts for these =
=3D3D
operations, the reasons I give are that the performance can be affected =
=3D
=3D3D
because the rbs operations are accesing the same TS that the DD and also =
=3D
=3D3D
that the rbs operations can make this ts grow to a huge size, I think =
=3D
=3D3D
those are valid and enough reasons to do it. Am I missing something =
=3D3D
else?=3D3D20
TIA
Gabriel
