Change sysdate on session level

Hi,
I am using Oracle 10.2.0.4 database.
My Application server is in USA and my database is in Germany. So we have 6 hours time difference between. So i need to set the sysdate to USA timings for a session who logs from USA.
How to change the sysdate in session level.
Regards,
Nv
Edited by: ORCLDB on Oct 24, 2011 2:33 PM

Thanks for the help !.
Is it possible some way by setting time_zone parameter. I tried as below
SQL> alter session set time_zone='Europe/Zurich';
Session altered.
SQL> select sysdate from dual;
SYSDATE
24.10.11
SQL> select to_char(sysdate,'dd-mm-yyyy hh24:mi:ss') from dual;
TO_CHAR(SYSDATE,'DD
24-10-2011 14:37:02
SQL> SELECT CURRENT_TIMESTAMP,SYSTIMESTAMP FROM DUAL;
CURRENT_TIMESTAMP SYSTIMESTAMP
24.10.11 11:08:01,281000 EUROPE/ZURICH 24.10.11 14:38:01,281000 +05:30But sysdate is not changing only current_timestamp changes.

Change characterset on session

Hi
I am pankaj.I want to change the characterset of my database.
I change the characterset of the database by alter system......cmd
Now I want to change it at session level.
Is is possible, How can i do this.
pl help

Hi Pankaj,
I hope you know what are you doing.
You shouldn't change your characterset on session level because the characterset on the client side depends on the OS of the client side.
If you change it to a different characterset you can destroy your database. You don't get any error messages or warnings

Can we change the DB character set at session level

hi,
Please help me
when iam giving the alter session command iam getting the error:
SQL> ALTER SESSION set NLS_CHARACTERSE
T =WE8MSWIN1252;
ALTER SESSION set NLS_CHARACTERSET =WE8MSWIN1252
ERROR at line 1:
ORA-00922: missing or invalid
i need to enter Arabic names in using the xml file.
here i have two questions
1)is it is possible to set character set at session level. because my client is not allowing to bounce the database. DB version is 10.2.0.4
Right now my DB is in US7ascii
2)is this "WE8MSWIN1252" set supports Arabic.
Regards,
Naresh

You cannot change the characterset at the session level. If you want to store ARABIC characters in your database then you should change the characterset of your database to any other characterset that supports Arabic characters or to a Unicode characterset like UTF8 or AL32UTF8.
If you try to insert Arabic characters with your present US7ASCII charancterset then the characters would be stored as junk.

How to measure undo at a session level

Below is what are trying to do.
We are trying to implement Oracle's table block compression feature.
In doing so, in one of our testing we discovered that the session performing the DML (inserts) generated almost 30x undo.
We measured this undo by using below query (before the transaction commited).
SELECT a.sid, a.username, used_ublk, used_ublk*8192 bytes
FROM v$session a, v$transaction b
WHERE a.saddr = b.ses_addr
However, above is at a transaction level since it still not committed, we would lose this value once the transaction either committed or rolled back, for this reason, we are trying to find an equivalent statistic at a session level.
1. What we are trying to find it out whether if an equivalent session level statistic exist to measure the amount of undo generated?
2. Is the undo generated always in terms of "undo blocks?"
3. When querying v$statname for name like '%undo%' we came across several statistics, the closest one
undo change vector size -in bytes?
4. desc test_table;
Name Type
ID NUMBER
sql> insert into test_table values (1);
5. However when we run the query against:
SELECT s.username,sn.name, ss.value
FROM v$sesstat ss, v$session s, v$statname sn
WHERE ss.sid = s.sid
AND sn.statistic# = ss.statistic#
AND s.sid =204
AND sn.name ='undo change vector size'
SID USERNAME NAME BYTES
204 NP4 undo change vector size 492
6. Query against: v$transaction
SELECT a.sid, a.username, used_ublk, used_ublk*8192 bytes
FROM v$session a, v$transaction b
WHERE a.saddr = b.ses_addr
SID USED_UBLK BYTES
204 1 8192
What are trying to understand is:
1. How can we or what is the correct statistic to determine how many undo blocks were generated by particular session?
2. What is the statistic: undo change vector size? What does it really mean? or measure?

Any transaction that generates Undo will use Undo Blocks in multiples of 1 --- i.e. the minimum allocation on disk is 8KB.
Furthermore, an Undo_Rec does not translate to a Table Row. The Undo has to capture changes to Indexes, block splits, other actions. Multiple changes to the same table/index block may be collapsed into one undo record/block etc etc.
Therefore, a transaction that generated 492 bytes of Undo would use 8KB of undo space because that is the minimum allocation.
You need to test with larger transactions.

How to Use Transient View Objects to Store Session-level Global Variables

hi
Please consider section "40.8.5 How to Use Transient View Objects to Store Session-level Global Variables"
at http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcstatemgmt.htm#ADFFD19610
Based on this documentation I created the example application
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.01.zip
It behaves as show in the screencast at http://screencast.com/t/qDvSQCgpvYdd
Its Application Module has a Transient View Object instance "MyEmployeesContextVOVI", as master for the child View Object instance "EmpInCtxJobVI".
On rollback the Transient View Object instance keeps its row and attribute values.
Also when passivation and activation is forced (using jbo.ampool.doampooling=false ) the Transient View Object instance seems to keep its row and attribute values.
questions:
- (q1) Why does the expression #{bindings.MyEmployeesContextVOVIIterator.dataControl.transactionDirty} evaluate as true when a Transient View Object instance attribute value is changed (as shown in screencast at http://screencast.com/t/qDvSQCgpvYdd )?
- (q2) What would be a robust approach to make a Transient View Object instance more self-contained, and manage itself to have only one single row (per instance) at all times (and as such removing the dependency on the Application Module prepareSession() as documented in "5. Create an empty row in the view object when a new user begins using the application module.")?
many thanks
Jan Vervecken

Thanks for your reply Frank.
q1) Does sample 90 help ? http://blogs.oracle.com/smuenchadf/examples/
Yes, the sample from Steve Muench does help, "90. Avoiding Dirtying the ADF Model Transaction When Transient Attributes are Set [10.1.3] "
at http://blogs.oracle.com/smuenchadf/examples/#90
It does point out a difference in marking transactions dirty by different layers of the framework, "... When any attribute's value is changed through an ADFM binding, the ADFM-layer transaction is marked as dirty. ...".
This can be illustrate with a small change in the example application
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.02.zip
It now shows the result of both these expressions on the page ...
#{bindings.MyEmployeesContextVOVIIterator.dataControl.transactionDirty}
#{bindings.MyEmployeesContextVOVIIterator.dataControl.dataProvider.transaction.dirty}... where one can be true and the other false respectively.
See also the screencast at http://screencast.com/t/k8vgNqdKgD
Similar to the sample from Steve Muench, another modification to the example application introduces MyCustomADFBCDataControl
at http://www.consideringred.com/files/oracle/2010/ProgrammaticalViewObjectAndRollbackApp-v0.03.zip
public class MyCustomADFBCDataControl
extends JUApplication
@Override
public void setTransactionModified()
    ApplicationModule vApplicationModule = (ApplicationModule)getDataProvider();
    Transaction vTransaction = vApplicationModule.getTransaction();
    if (vTransaction.isDirty())
      super.setTransactionModified();
}Resulting in what seems to be more consistent/expected transaction (dirty) information,
see also the screencast at http://screencast.com/t/756yCs1L1
Any feedback on why the ADF Model layer is so eager to mark a transaction dirty is always welcome.
Currently, question (q2) remains.
regards
Jan

Setting Session level parameter in FORMS 10g

Hi folks,
I want to setup session level setting for NLS DATE FORMAT in FORMS 10g at environment settings. because, i can't change these setting at database level. b,cz different client applications (i.e. .NET,Forms 10g and SQL PLUS) using different settings.
So, i want to set this NLS DATE FORMAT for SESSION level in FORMS 10g.
can i include this in default.env, if yes, how to include that one in .env file
Edited by: user12212962 on Jul 23, 2010 7:18 PM

No, i want to setup the session parameter for DATE FORMAT. why because, i'm executing oracle stored procedure from forms and this procedure does some logic based on date value.
In this procedure, i have used all variables as DATE datatype only. and i can't change this procedure due to some other client application's using same procedure like JAVA, .NET, Oracle BI and scheduled jobs. And all these application's working fine, even when i use forms 6i also it's working.
but when we use FORMS10g, date was treating as DD-MON-RR and all other client applications using DD-MON-YYYY due to session level setting and at database level also has a same format i.e. DD-MON-YYYY. because i logged this NLS value in audit_table when i executed through FORMS10G, JAVA application,.NET
May be some where it's changing this setting to DD-MON-RR for FORMS10g. Is any settings at Oracle APP server level
(iAS) for this parameter?

Session level NLS_COMP NLS_SORT not inheriting from instance parameters???

Hi all,
I have an Oracle 11g installation with a database setup as follows: NLS_COMP=BINARY, NLS_SORT=BINARY.
After playing a bit at the session level with NLS_COMP=LINGUISTIC and NLS_SORT=BINARY_CI, I persisted them at the instance level via ALTER SYSTEM with SCOPE=SPFILE.
Bounced the database and voila, when I query nls_instance_parameters it reflects my changes.
Problem is, my parameters are not applied to my session: in fact, if I query nls_session_parameters, both are still set to BINARY. (Note: using sqlplus).
The documentation (http://download.oracle.com/docs/cd/B28359_01/server.111/b28310/create006.htm) states:
"A new session inherits parameter values from the instance-wide values."
Am I missing something here? Is sqlplus somehow overriding the instance-level parameters? (I know sql developer may, depending on your options, hence I went back to basics...).
Any help appreciated!
Thanks in advance,
Paolo

Hi Sergiusz,
Thank you again for your reply.
In my registry NLS_LANG is set to its default value (AMERICAN_AMERICA.WE8MSWIN1252), so I assume that unless I set anything specific in my environment, NLS_COMP and NLS_SORT are affected by that and sort of reset to BINARY?
If this is the case, then I'm struggling to understand the purpose of setting them at the instance level, given that as you said, NLS_LANG shouldn't be removed as an environmental variable and it seems to override them?
Along the same lines, if I understand this correctly, should I have no control over the environment that my application runs in (e.g. a web application running in a shared IIS app pool), then the only option left is (re)setting my variables every time I establish a connection with the Oracle db, thereby starting a new session?
Really appreciate your help.
Cheers,
Paolo

Change PGA for session?

Hi there,
we are developing an OLTP application on 11gR2. As a consequence of having a lot of small transactions, we have configured a relatively small PGA and a lot of SGA memory and have configured the optimizer relevant parameters for choosing b-tree index paths.
Still we are going to have some batch Jobs, running during the non-office hours. Now my problem is, how to change the DB configuration session-wise, to be more DWH-like. While I can change the optimizer settings session wise, I have problems changing the PGA for a session.
How would you solve the problem? One solution could be to change from automatic PGA memory management to manual, that is to setting the %_AREA_SIZE parameters. These parameters can be changed session wise. But this would very much affect the behaviour of the overall system.
Any idea? What is the standard solution for such issues?
Many thanks in advance.

Thank you, that's it I think. My misunderstanding was that I had only looked at the PGA_AGGREGATE_TARGET parameter. Setting this parameter to 0, automatically sets the workarea_size to manual. Only difference is: pga_aggregate_target can only be changed on the system and not on the session level. So my solution is to change the workarea_size parameter to manual in the session and to set the xxx_area_size parameters as necessary. Thanks for the help. Sometimes the solution is there, but you just don't see it. :-)

I have made very good experience with these settings. I actually got the idea some years back from the book of Tom Kyte "Effective Oracle by Design". The default values
optimizer_index_caching              integer     0
optimizer_index_cost_adj             integer     100are good for DWH environments. For OLTP apps the following setting can be better:
optimizer_index_caching              integer     90
optimizer_index_cost_adj             integer     25As you know the cost estimations of the optimizer are relative. So these parameters influence the decisions of the optimizer to rather choose index-paths or rather full table scans. The OLTP settings have been proved in my projects as recommendable.
Thanks.

Session level auditing

Hi everyone,
I need oracle document ID for session-level auditing in oracle 10g.If you 've any steps to do auditing in session level,kindly post it.
Thanks
Jaya prataab J

Do you really mean "audit" as in "information that gets written to the database audit trail"? Or do you mean to ask how to trace a session?
If you really mean audit as in the SQL statement keyword (i.e. AUDIT SELECT ON emp ...), I'm rather unclear on how you would expect that sort of functionality to work. Auditing is necessarily configured long before the session even exists. And an audit trail that just had audit records from a few select sessions would seem rather pointless as you'd never know what changes were made in unaudited sessions.

Session level character set

The below are my character set in my DB
NLS_CHARACTERSET=WE8ISO8859P1
NLS_NCHAR_CHARACTERSET=UTF8
Correct Answer (If I use english language the result is correct)
==========
select product(',','AB_BC ,DE') from dual;
(AB_BC, DE,,,)
After altering the parameter at session level to get Japanese character set I am getting wrong result
ALTER SESSION NLS_SORT=JAPANESE_M_AI
ALTER SESSION NLS_COMP=LINGUISTICS
it is giving me wrong result (I should get the above result)
=================
select product(',','A_BC ,DE') from dual;
(AB, BC , DE,,,,)
How to change at session leavel to get Japanese character set

Ok,
Let's provide the broad picture, as your setup and your commands are incorrect.
You set the characterset of the database to a characterset the O/S supports.
Whether or not you have characterset conversion on the client side is determined by NLS_LANG.
You set NLS_LANG to a characterset the client O/S supports. Ie if you are running on Windows (as always you provide no details at all), the regional settings of the O/S must have been set to Japanese.
WE8ISO8859P1 is the Latin-1 alphabet and doesn't support Kanji.
Also the command you specify deal with sorting of the data, not with the characterset itself.
Also no one can tell what
select product(',','AB_BC ,DE') from dual;
constitutes.
In summary: you don't seem to be reading documentation, or you only look at it.
None of what you have posted makes any sense, and clearly shows you didn't try to understand the NLS concept.
Yet again: you don't provide platform and version info
Yet again: you don't specify any background.
If you want help, you need to provide as much info as possible.
You should not require anyone here to tear the information out of you.
After all: everyone here is a volunteer and doesn't get paid to help you out, but is spending his/her time.
If you want to continue to post in this fashion, maybe you should find a forum of mindreaders.

Why can't I change the transaction isolation level?

How to restrict header text changes in sales order level

Dear Experts,
how to restrict header text changes in sales order level change mode
thanks

Hello Chandu,
how to restrict header text changes in sales order level change mode
In order to restrict changes to Sales Order Header Text, the appropriate User Exit would be USEREXIT_MOVE_FIELD_TO_TVCOM_H. With the help of ABAPer, you can include the simple logic on the basis of Header Text type such that whenever any changes are incurred on the Sales Order header text, updates would be prevented.
Please try out this approach and let us know your latest observation on this issue.

Enable change logs for item level of Sales Document

Hi,
On transaction VA02, additional screen field (Booking Date) is added (& consequently 2 appends with date field in the tables VBAK & VBAP).
When this date is changed in the header, the corresponding dates are changed in the item level as well.
However, the change documents are created only for table VBAK (though item data is updated in VBAP also).
When the date is changed at the item level, the change logs are created for the corresponding field in table VBAP.
The data element has 'Change Document' checked.
How can I activate the change to be logged for the item level (VBAP), when the date is changed at header level (VBAK)?

Hi Nidhi,
Maybe set a breakpoint in include MV45AF0C_CHANGE_DOCUMENT_CREAT
Then check in UPDATE debug mode the value of upd_vbap and the contents of xvbap which are passed on to function VERKBELEG_WRITE_DOCUMENT .
This function creates the change documents based on the data changes.
I would have thought that since the date values are changed at item level as well when you only change it at the header, they should get a change document created automatically, since the dates must be in the XVBAP table (as their value is changed at the DB).
So I would compare the various internal tables for both scenarios (header change, item change) to determine their differences.
After this use one of the user-exits to populate the internal tables for the header scenario based on the values of the item scenario. I would feel this to be a last resort though, since something appears not to be working correctly (I think).
Hope this makes sense,
Robert

BAPI to change data at operation level

Hi,
I have this requirement:
I need to change data at operation level, more particularly Person No (PERNR) by using a BAPI.
Is there any BAPI - in which I can pass the basic data (say Order data and Operation data) and change the PERNR for it.
The name of the BAPI and its usage will help.
Ankur

Hello,
Assuming you are talking about maintenance or service orders, you can use BAPI_ALM_ORDER_MAINTAIN. See function module documentation from SE37. The structure BAPI_ALM_ORDER_OPERATION contains PERS_NO field.
