FWIW, do not place the terminating semicolon in the execute string, ie,

begin
  execute immediate 'Alter session set OPTIMIZER_MODE = choose' ; end ;

Hi all

Ok if I execute these commands/SQL in sqlplus it works. When I add to the trigger for after logon it
does not work.

I get the feeling it is only valid for the current block, begin -> End.

Any ideas to work around this.

grant alter session to smload;

drop trigger olap_logon_trigger;

create or replace trigger olapl_logon_trigger

  after logon on smload.schema

begin

  execute immediate 'Alter session enable parallel query;';

  execute immediate 'Alter session set SORT_AREA_SIZE = 10485760;';

           execute immediate 'Alter session set OPTIMIZER_MODE = choose;';

           execute immediate 'Alter session set CURRENT_SCHEMA = SIEBEL;';

           execute immediate 'SET TRANSACTION USE ROLLBACK SEGMENT RBBIG01;'; end;

/

            Altering "current_schema", you will not see anything in
"user_tables", but you should be
            able to reference tables in this new schema without using
"siebel" prefix.

             Hi all





             Ok the trigger has been changed to this, It compiles.





             The problem now is that all the objects that need to be access
is owner by the siebel
             user. I do not want to create synonyms. The tool being used can
not append the siebel
             schema name in front of the objects, and it is expecting to log
in as siebel.

             Any idea why the 'Alter session set CURRENT_SCHEMA = SIEBEL;' is not changing my

             current schema. I have tried executing Alter session set CURRENT_SCHEMA = SIEBEL; in a

             standard sqlplus window and then looking at the user_tables table and it is empty ?

             create or replace trigger olap1_logon_trigger

               after logon on smload.schema

             begin

               execute immediate '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;';
                     execute immediate 'Alter session set CURRENT_SCHEMA =
SIEBEL;';              end;
