Hi Mike
Siebel has released a note whereby they approve CBO for the EIM process.
Also what I have is a SM Data warehouse logon into the OLTP Siebel db. The activities this logon does is more akin to OLAP. So what I am doing is giving this logon a big sort area size, enabling parallel access for the user, setting it's session to CBO etc etc.

In looking at this and thinking about it...doesn't any DDL statement do an implied COMMIT? If so, the first "EXECUTE IMMEDIATE" will fire, commit, the SET TRANSACTION will be released, and the user will not be assured of using that rollback segment. Shouldn't the SET TRANSACTION be the last statement in the trigger?
And if Siebel wants RBO, doesn't changing the optimizer at the session level mean that all that session's queries will be performed using CBO? Is Siebel OK with that?
Cheers,
Mike

"Alter session ..." is not DML, so I think you need to use dynamic SQL:
create or replace trigger smload.logon after logon on database
begin
SET TRANSACTION USE ROLLBACK SEGMENT RBBIG01;
EXECUTE IMMEDIATE "Alter session enable parallel query"; EXECUTE IMMEDIATE "Alter session set SORT_AREA_SIZE = 10485760"; EXECUTE IMMEDIATE "Alter session set OPTIMIZER_MODE = choose";end;
