Objet: RE: ORA-01595
How large are the rollback segments?
The ORA-01594 error states:
attempt to wrap into rollback segment (string) extent (string) which
is
being freed
Cause: Undo generated to free a rollback segment extent is
attempting to
write
into the same extent due to small extents and/or there are too many
extents
to
free.
Action: The rollback segment shrinking will be rolled back by the
system;
increase the optimal size of the rollback segment.
Can you try increasing the OPTIMAL parameter for the SYSTEM rollback
segment? Typically the SYSTEM rollback segment is created much
smaller than
the "public" rollback segments..

I am trying to do this.
alter rollback segment SYSTEM shrink;
alter rollback segment R01 shrink;
alter rollback segment R02 shrink;
alter rollback segment R03 shrink;
alter rollback segment R04 shrink;
alter rollback segment SYSTEM shrink
*
ERROR at line 1:
ORA-01595: error freeing extent (1) of rollback segment (0))
ORA-01594: attempt to wrap into rollback segment (0) extent (1)
which is
being
freed
And only on rollback system I got an error. There are no
transcations in
this RBS.
Any Idea.

It looks like you only have 1 extent within the system
rollback
segment
anyway?
Why are you trying to shrink it? Do you have other rollback
segments
in
place?
