A question about RBS

Hi:

Oralce 8173 on Sun box. RBSLMT size is 2G.

First I got this when a delete statement was run. There was no any other
transactions running during the whole thing.

ORA-1650: unable to extend rollback segment RBS007 by 16 in
tablespace RBSLMT

Then I found:

select segment_name, bytes from dba_segments where segment_name like 'RBS%';

SEGMENT_NAME                 BYTES
-------------------------------- ----------
RBS001                   119537664
RBS002                   96862208
RBS003                   237633536
RBS004                   89653248
RBS005                   762052608
RBS006                   371982336
RBS007                   354549760
RBS008                   115081216

8 rows selected.



select sum(bytes) from dba_segments where segment_name like 'RBS%';

SUM(BYTES)
----------
2147352576




Now I did the delete again (use the largest rbs from above info):

SQL> set transaction use rollback segment RBS005;

Transaction set.

SQL> delete from termhistory where historyid=19;

915798 rows deleted.

SQL> commit;

Commit complete.


My question is why the "delete" worked this time? I thought one RBS will
take over other RBS's space automatically if necessary. Since there is no
other transactions going on, which ever RBS (picked up by the tsansaction)
should not matter.

Thanks.

Guang
