'alter session' command generating a vast number of audit files

Oracle: 10.2.0.5
OS: HP Itanium.
We have requirements to turn on auditing to the operating system for security purposes. We have only set the init.ora parameters and have not actually enabled any sql statement tracing yet. The parameters we have set are:
audit_file_dest
audit_sys_operations=true
audit_trail =xml, extended (the xml is based on requirements).
We have a login trigger that runs 'alter session set current_schema=<>' This has been a part of the application for years. Every time someone logs in this gets set.
We are getting 1 trace file every time this is run.
Is this from the audit_sys_operations?
I ran some queries of the Audit views and I don't think we have anything turned on. This is an old legacy system so someone may have issued some commands at some point in the past. There are a lot of views and I may have missed this.
How do we disable auditing the 'alter session commands' ?

Hi,
You could try: noaudit alter session;

How to tell if a user is issuing 'alter session statements'

When I run 'alter session' from sqlplus in my schema, this does not get parsed and go to v$sql or show up in v$open_cursor. I have a user that is running queries from informatica. He says he is passing alter session statements through informatica, I want to see if they actually get there. The person is not real versed in oracle and I don't know informatica.
i cant turn on trace cause he connects and disconnects and this would run immediately, I am not in a position to turn on system level tracing, add a trigger, or turn on auditing (not allowed).
anyway to tell from a data dictionary view or something like that if these were issued by a given session? The queries run for a few minutes, so I have a bit before his session disconnects to query the data. I can't get him to change his code to stay connected. Is there a view that shows parameter changes for a given session?
oracle: 10.2.0.5
4 alter session commands are:
Alter session set sort_area_size=999999999;
Alter session set hash_area_size=999999999;
Alter session set db_file_multiblock_read_count = 128;
alter session enable parallel dml;

i cant turn on trace cause he connects and disconnects and this would run immediately, I am not in a position to turn on system level tracing, add a trigger, or turn on auditing (not allowed). If Informatica connects to Oracle via network, capturing TCP/IP traffic and mining in it may be your last resort.
you can get session's PDML status from
select pdml_status from v$session;
i cant turn on trace cause he connects and disconnects and this would run immediatelythis contradicts to your following statement
The queries run for a few minutes, so I have a bit before his session disconnects to query the data.
I can't get him to change his code to stay connected. Informatica should have debug. Ask him if he can go step by step.

Alter session set NLS_DATE_FORMAT and to_date not working

Hey folks,
for the sake of simplicity let's assume i want to get the current system time from the table dual in a certain format, e.g. 'YY.MM.DD'.
Currently the query
select sysdate from dual;
yields:
07-JAN-08
The desired output should look like this:
08.01.07
So, according to the manual, i tried the following:
alter session set NLS_DATE_FORMAT = 'yy.mm.dd';
No effect, date is still displayed as
07-JAN-08
Even the following query:
select TO_DATE (sysdate, 'yy.mm.dd') from dual;
yields
07-JAN-08
What am i doing wrong here?
Additional information:
-> DB is Oracle 9
-> I am using the Oracle SQL Developer under Ubuntu Gutsy
-> No, i did not forget to commit my commands....:-)
Any ideas?

select TO_CHAR (sysdate, 'yy.mm.dd') from dual;However the alter session command should work:

Oracle Alter Session not working in CF9

Hello,
I'm trying to understand differences between CF5 and CF9 when I retrieve numbers and dates from an Oracle Database.
The code I ran on CF5 and CF9 servers :
<cfoutput>
<cftransaction>
<cfquery datasource="intranet">
alter session SET NLS_TERRITORY = FRANCE
</cfquery>
<cfquery name="qry" datasource="intranet">
select
     TO_NUMBER(12345/10) as nbr,
     sysdate as dt,
     TO_CHAR(1234.56,'L99G999D99') as cur
from dual
</cfquery>
</cftransaction>
#qry.nbr#<br>
#qry.dt#<br>
#qry.cur#
</cfoutput>
I've got those outputs :
Result in CF5
Result in CF9
1234,5
01/12/09
¿1.234,56
1234.5
2009-12-01 19:16:04.0
¿1.234,56
The first two rows in CF5 display data in French format. That's not the same for CF9, the data are in American format.
Then I changed the NLS_TERRITORY parameter
alter session SET NLS_TERRITORY = AMERICA
Result in CF5
Result in CF9
1234.5
01-DEC-09
$1,234.56
1234.5
2009-12-01 19:20:39.0
$1,234.56
The two first row haven't changed in CF9, it seems that the "alter session" has no effect on number and date format in query results. Is that a bug or am I misunderstanding something ?
Regards,
Maxime

Thank you for your reply.
I tried what you've suggested on the CF9 server.
The results are :
NLS_TERRITORY =
1) oracle JDBC database
2) oracle JDBC thin client
3) oracle JDBC-ODBC bridge
AMERICA
1234.5
2009-12-02 13:24:30.0
$1,234.56
1234.5
{ts '2009-12-02 00:00:00'}
$1,234.56
1234.5
2009-12-02 13:24:30.0
$1,234.56
FRANCE
1234.5
2009-12-02 13:29:53.0
¿1.234,56
1234.5
{ts '2009-12-02 00:00:00'}
¿1.234,56
1234.5
2009-12-02 13:29:53.0
¿1.234,56
The behavior is pretty much the same in the three differents ways to call the database. The only difference is on the date display using the Oracle JDBC thin client, which is another format from those I've already got.

Maxime

How to add alter session to report query !!

Hi all,
I need to add
alter session set "_optimizer_cost_based_transformation"=off
before select query runs in Oracle discoverer.
Recently I encountered with ORA 00600 bug and this is the way it can be solved.
Before running the query, the session should be altered.
Any ideas is appreciated..
Thanks

Hi,
Your best option may be to turn the cost based transformation off using a logon trigger. It will then be turned off for all Discoverer sessions. You will need to create a package procedure that executes the alter session command. Then call this procedure either from a Discoverer logon trigger, or a database trigger that checks that the session is a Discoverer session. Or if you are using the eBS you can use the Applications initialization profile.
However, an alternative approach may be to use a hint in the query. For example, you can set the optimizer features back to previous version that does not have this optimizer feature e.g. using:
/*+ optimizer_features_enable('9.2.0') */
Then put this hint in the query using a view. I am not sure that ther is a hint which will turn just this feature off.

See if you have any on-login triggers that could be issuing an incorrect alter session command. Also see if the error occurs as other users (if possible)
If this was SQL*PLUS I'd also check the login.sql and glogin.sql files but I don't think sql*developer uses those.

Alter Session, same user

Good night community,
I have issued a command Alter Session to set a different NLS_DATE_FORMAT for only one session of an user but, the other sessions of the same user (yes, the application here use all the same database user) got the changes.
Is that predictable to happen? Is there a clausule to issue Alter Session only for a specific session of that user?
Thank you very much!
PS: If this is not the right place to ask this, could you move it? Thank you very much!

>
Show us the proof that you got that result. Post your 4 digit Oracle version and show us the sql*plus sessions you have created and the actual ALTER SESSION command you executed.
ALTER SESSION has NO affect on other sessions whether those 'other' sessions are for the same user or not. A 'user' is NOT a session.

Dynamic number of xml files with a specified max size

Hi all,
I'm using a custom report to generate xml files (via a ST program and a call transformation) containing
data belonging to is-u invoices (some are much more complex and rich of data than other ones).
I'm asked to generate the minimun number of xml files, the only limit is their maximum size (40 MB).
How can I dynamically understand when I need to save an xml file and generate the next one if the
size is only readable after the transformation,as far as I know?
Thanks a lot in advance for your ideas.
Angelo

My problem is that different users may be loading different files.
As there may be many simultaneous users and the xml document nodes do not get edited in any way, I only want to have one copy of each file in memory .... hence the application scope.
If I make the var name fixed then a user loading xml2.xml would overwrite any previous file xml1.xml or whatever.
I could switch to session scope but that would load possibly hundreds of copies of any given file at any given time and the files are not small :-(

Execute sql command "ALTER SESSION SET..."

How can i execute command "ALTER SESSION SET NLS_DATE_FORMAT ='MM/DD/YYYY'" with JDBC
api.
And by default?
Bye
Ste

I'm not sure that you want to do this in Java. I would imagine that the NLS_DATE_FORMAT would be set by the Oracle DBA, and shouldn't be changed by a Java app via JDBC.
Besides, when you query the database for a date it's returned as a java.sql.Date, regardless of the settings in the database. Once you have that, you can format it according to your wishes by using java.text.DateFormat and java.text.SimpleDateFormat.
I thought the point was that the JDBC driver took care of ensuring that you got java.sql.Date objects back from queries, regardless of the NSL_DATE_FORMAT setting in the database.

Alter session attributes in OBIEEreports

Hi All,
I want to know whethe I can 'alter session' before the SQL generated by OBIEE automatically?
If yes, how should I configure it?
Thank you in advance.
Leon

Hi Leon,
I think that option a) is used for each connection and option b) for each SQL statement.
Maybe something is available in the front-end that will enable you to execute the ALTER SESSION ahead of a specific statement... but I am not aware of that.
If you want to use ALTER SESSION only for SQL commands on a specific set of tables, you can try to create a new physical database / business model / presentation catalog specifically for those requests? Then you can use option a) and or b)..

Marco

Hi:
It seems when you are starting RMAN it's executing some commands (one 'ALTER SESSION...'. It's seems to be a batch which has a bad value for SORT_AREA_SIZE. Find it and modify to a proper value as message shows. If you can't find start RMAN by calling directly the executable ($ORACLE_HOME/bin/rman or %ORACLE_HOME%/bin/rman.exe).

Execute immediate 'alter session set current_schema = ' failed in PL/SQL

Hi
I am trying to run
EXECUTE IMMEDIATE 'ALTER SESSION SET CURRENT_SCHEMA = TEST ' ;
in a pl/sql block but it is failing.Can anyone update me on this.
CREATE OR REPLACE PROCEDURE test3
IS
A_COUNT NUMBER(15);
BEGIN
EXECUTE IMMEDIATE 'ALTER SESSION SET CURRENT_SCHEMA = TEST ' ;
SELECT COUNT(*) INTO A_COUNT FROM (
select id from solutions );
END;

The user who owns the procedure needs to be granted direct select rights on table test.solutions (not via a role). Still will not help. Look what OP is trying to do. In a stored procedure owned by some user (other than TEST) OP is trying to reference user TEST owned table solution without prefixing it with owner. Something like:
SQL> create table u1.test_tbl(x number);
Table created.
SQL> select * from test_tbl;
select * from test_tbl
ERROR at line 1:
ORA-00942: table or view does not exist
SQL> alter session set current_schema = U1;
Session altered.
SQL> select * from test_tbl;
no rows selected
SQL> However, OP tries to do it in a SP using dynamic SQL to change current schema to test. Such change will occur when SP will be executed, not when is it compiled. At compile time we are still under SP owner's schema and therefore select from solutions implies table solutions owned by SP owner, not by TEST. The only way to make SP compile and work OK is to select from solutions also dynamically:
SQL> select sys_context('userenv','current_schema') from dual

ALTER SESSION in sql script produces strange results

Why would "alter session set NLS_DATE_FORMAT" interfere with the operation of a sql script?
First, the script without the ALTER SESSION:
SQL> !cat doit1.sql
--alter session set NLS_DATE_FORMAT = "DD-MON-YYYY"
set pagesize 99
set trimspool on
col BIRTH_MONTH for a11
break on BIRTH_MONTH skip 1
spo doit.txt
prompt My Membership
set feedback off heading off
select 'As of ' || sysdate from dual;
set heading on
select count(*) from dual;
spool offAnd its execution:
SQL> @doit1
My Membership
As of 14-JAN-10
COUNT(*)
1All's well with the world. Now let's throw in the ALTER SESSION:
SQL> !cat doit2.sql
alter session set NLS_DATE_FORMAT = "DD-MON-YYYY"
set pagesize 99
set trimspool on
col BIRTH_MONTH for a11
break on BIRTH_MONTH skip 1
spo doit.txt
prompt My Membership
set feedback off heading off
select 'As of ' || sysdate from dual;
set heading on
select count(*) from dual;
spool offAnd its execution
SQL> @doit2
set pagesize 99
