Hi Jared,

I just now Tried it and it was working.

But i have tried it in 8.1.6 and it has failed to execute for the users granted the DBA Role.

Anyways when i checked at
http://asktom.oracle.com/pls/ask/f?p=4950:8:329387::NO::F4950_P8_DISPLAYID,F 4950_P8_CRITERIA:1844531724208,%7BAfter%7D%20and%20%7BLogon%7D

This iw what he said.

This is the correct behavior and is designed to make it so your database doesn't
get into a state whereby NO ONE can log in (815 can get to that state). It is a
feature.

My suggestion, don't use the DBA role. Create your own ROLE (create many of

them in fact) YOUR_DBA and use that instead. DBA is just a role (but a special
one). If you don't use "DBA", you will be able to treat your DBA users as if
they were any ordinary user.

Your comments pls.

I've done many tests and this is not right. It fires for users with DBA.

The only thing I remember (may be I'm dreaming )when I first used it in 8.1.5 on NT is that the logon trigger did not run under the user who is logging on but under the pseudo process number 1.

This is not the case any more.

Waleed

Ganesh,

Are you sure about logon triggers not firing for users with the DBA role enabled?

I've used them on 8.1.6 and 8.1.7, and they fire on my DBA account.

                    Please respond

                    to ORACLE-L

Create it Once not every time some one Logs in...

The table is notsimilar to temporary tables in SQl... They are Different..

The Table is visible to all sessions if u say they are Global temporary Tables.

Yes Logon triggers Fire Every time the User logon... But the second time onwards u will get a Error... The Logon triggers dont fire for Users with the DBA Role Enabled.

     Hi

     I am trying to use an after logon trigger to create a session temp
     table rather that create it at the time the procedure that uses it
     calls it. Two reasons for doing this is for performance ? the other is
     so that I can reference it in a cursor.

     1) Do logon triggers not work if I logon with toad or similar tools

     2) If 1 is wrong why when I have the following trigger in the database
     cant I see the table or use it after logging on

     TRIGGER create_temp_table
     AFTER LOGON ON DATABASE
     DECLARE
     v_CreateString VARCHAR2(100);
     BEGIN
     v_CreateString := 'CREATE GLOBAL TEMPORARY TABLE t_tmp_stddev ( v_part
     NUMBER, readings NUMBER) ON COMMIT PRESERVE ROWS';
     EXECUTE IMMEDIATE  v_CreateString;

     END;

     TIA
