Audit dml vs noaudit dml - session stat huge difference in redo size DB 9.2

Hi,
I've just finished test ,where compared audit update table, delete table, insert table by user by access with noaudit dml statements.
DB version is 9.2.0.8 , same test run twice on same configuration and data so its comparable .
What concerns me the most is difference in redo size ,and redo entries , here goes table with results:
noaudit            audit              statname
486 439,00     878 484,00     calls to kcmgas
40 005,00     137 913,00     calls to kcmgcs
2 917 090,00     5 386 386,00     db block changes
4 136 305,00     6 709 616,00     db block gets
116 489,00     285 025,00     deferred (CURRENT) block cleanout applications
1,00     3 729,00     leaf node splits
361 723 368,00     773 737 980,00     redo size
4 235,00     50 752,00     active txn count during cleanoutCould You explain that differences in statistics, especially in redo size.
I'm suprissed because in 9.2 DB audit dml doesnt log actual sql statements, only indication of usage .
Regards.

DML Error logging for Update statement

Hello,
I am facing a problem with regard to DML Error logging with Update statement .
oracle : 10.2
I am executing following DML update:
BEGIN
UPDATE
table_1 a
SET a.Exp_DATE =a.EFF_DATE
WHERE a.col_a1 != (SELECT b.colb1
                     FROM table_2 b
                     WHERE a.msisdn =b.msisdn )
LOG ERRORS INTO table_1_ERR REJECT LIMIT UNLIMITED;
END ;    I was expecting that "ORA-01427: single-row subquery returns more than one row" would be captured in LOG error table "table_1_err"
but instead I got run time error and whole dml was rolled back.
Please let me know whether this exception is not captured by DML error logging.
Thanks,
Abhishek

*Oracle logs the following errors during DML operations:** Column values that are too large.
* Constraint violations (NOT NULL, unique, referential, and check constraints).
* Errors raised during trigger execution.
* Errors resulting from type conversion between a column in a subquery and the corresponding column of the table.
* Partition mapping errors.

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.

Row fetching, session state, multi-page processing of 1 row - problems

I'm building an application that's updating a couple of tables via an updateable view and an instead-of trigger. That portion of it works OK, EXCEPT for the problems that I'm having with the APEX end.
I've got 3 pages; the first page reads the row in via the automated row fetch and has, say columns 1-20.
Page 2 has, say, columns 20-40 and page 3 has the remainder.
I have the row fetch set up conditionally so that it only executes the first time that page 1 is displayed. All the columns are set as Database Columns.
It seems that if I fill in fields on page 1, move to page 2, and back to page 1, the contents of the fields on page 1 are destroyed unless I set their 'Source used' to 'Only when the current value in session state is null'.
Furthermore, upon update (which is on page 3, via an automated row update), the only columns that get updated are those that exist on page 3. The column values from the other pages no longer exist.
Does navigation to another page not retain the session-state of database-column items?
Am I better off just writing my own processes to perform the updates?
Any other suggestions?
Frank

Hello Frank,
>>I have the row fetch set up conditionally so
that it only executes the first time that page 1 is
displayed …
It seems that if I fill in fields on page 1, moveto page 2, and back to page 1, the contents of the
fields on page 1 are destroyed unless I set their
'Source used' to 'Only when the current value in
session state is null'.
It seems that the first sentence is not consistent
with the second one. The only reason the values are
destroyed, as you call it, is that the ARF is running
again. What condition are you using on your ARF?
In any case, the right way to deal with it is to
change the source used to "Only …", as I understand
you already did.
Hi Arie,
I set an item after the first ARF. I then have the ARF set to execute conditionally based on the presence of that item. (I also display a success message on the ARF, so I know that the ARF is only occurring once). I move to subsequent pages by submitting the current pages.
>>Does navigation to another page not retain the
session-state of database-column items?
Navigating to another page does retain the session state values.
It's depends on what you mean by navigating.
Submitting the page set/update session state.
Redirect without submitting the page will not
set/update the session state.
>>Furthermore, upon update (which is on page 3,
via an automated row update), the only columns that
get updated are those that exist on page 3. The
column values from the other pages no longer
exist.
Automatic DML is working only with the current page
items. You can't use it to insert/update other page
items, even if they are in session state. However, in
your case, it's not the Automatic DML performing the
actual updates, but your triggers. Are your triggers
relying on session state values?
I think this statement 'Automatic DML is working only with the current page
items.' answers my question. My trigger is working on session state values. It's an 'instead-of' trigger, so I was letting the automatic DML perform the 'update' on the view, while allowing the trigger to do the actual update of several tables that the view joins by referring to their :NEW. values in the trigger. Since the DML occurs on my last page, those were the only session state values that my trigger ultimately saw.
>>Am I better off just writing my own processes to
perform the updates?
I believe the correct way is to submit the page and
then branch to the next one. Submitting the page will
save all your items in session state, and allow these
items to be available for page 3 DML.
Regards,
Arie.I'm doing that already - all the values do appear to be in session sate, except only the items that are on the last page actually make it to the automatic DML update, which seems to agree with your previous statement.
I suppose I could write my own process to perform the update, as the values are available in session state.
Thanks,
Frank

Need help with the session state value items.

I need help with the session state value items.
Trigger is created (on After delete, insert action) on table A.
When insert in table B at least one row, then trigger update value to 'Y'
in table A.
When delete all rows from a table B,, then trigger update value to 'N'
in table A.
In detail report changes are visible, but the trigger replacement value is not set in session value.
How can I implement this?

You'll have to create a process which runs after your database update process that does a query and loads the result into your page item.
For example
SELECT YN_COLUMN
FROM My_TABLE
INTO My_Page_Item
WHERE Key_value = My_Page_Item_Holding_Key_ValueThe DML process will only return key values after updating, such as an ID primary key updated by a sequence in a trigger.
If the value is showing in a report, make sure the report refreshes on reload of the page.

Corrupt Session State? - Apex form posts text value as Null

Recently I've discovered an issue with our Apex installation in which any value chosen as a source for a text field ends up being posted as a null to the database.
We are running APEX version 3.2 within an Oracle 10.2.0.4 database using the Oracle HTTP Server from the 10g companion disk.
At first glance, everything appears to function as expected; I have created a simple table called "oracle_sr" with 2 columns both not null:
SQL> desc capacity.oracle_sr
Name Null? Type
ORACLE_SR_ID NOT NULL NUMBER
TIMESTAMP NOT NULL DATE
Within APEX the form wizard was used to create a form on this table.
After executing the pages and entering a value for the timestamp field I can create records without issue.
The issue arises when I choose a source value for the timestamp field.
Any of the source options result in the same error (including a static value) so I will focus on the SQL Query for the source as:
select sysdate from dual;
This should substitute the system date within the timestamp text field when the page is executed.
As expected, the value appears in the text box but when I submit the form to create the record I receive the error:
ORA-01400: cannot insert NULL into ("CAPACITY"."ORACLE_SR"."TIMESTAMP")
I have been working with APEX for quite some time and have successfully used this technique in many applications but just started to see this error over the past few days. What is particularly odd about this message is that default "not null" validations created by the form wizard sees the timestamp filed as having a value. The session state information included below is reporting a value yet the database is throwing the ORA-01400.
Has anyone experienced a similar issue? I've spent a fair amount of time trying to research this issue but cannot seem to find any similar posts.
I have included the debug output from my test page, from what I can see, there does seem to be a value associated with the timestamp filed:

If you changed the Source Type of an item from Database Column to something else, then it cannot participate in the Automated Row Fetch/Automatic Row Processing (DML) choreography. You should leave the Source Type as it was and change the item's Default Value to populate it when the ARF process fetches a null for the column.

Controlling Session State and Submit Processing

I am trying to gain a fundamental understanding of how to control submit processing and session state, etc.
For example, I have a popup lov that lists names and returns id for the parent record. When the user make the selection using this pop lov, I then have an id that I want to use to lookup the default value for another field.
How do you submit a page for re-rendering (i.e, you have condition expressions referencing values that the use has set) without triggering the auto dml and page branch?
For example, I have a form for specifying tns names with 2 buttons, 'Advanced Config' and 'Basic Config'. The idea is to hide/show items corresponding to basic or adv. config options, etc.
My first approach was to have the buttons do a redirect to the same page, setting P5_USE_ADV_CONFIG_YN to Y or N without clearing the cache. When the page refreshes, the conditional rending has occured as desired (i.e., I set the condition on my form items to reference P5_USE_ADV_CONFIG = Y or N, etc.), but user's data values have been lost since the record was reloaded from the database.
So..I tried putting a condition on the fetch procedure to prevent the record from being re-read. However, this left all the fields empty which indicates that the item's session state has been completed cleared! Huh? I didn't want ask for or want this behavior. Hmmm.
So, I start thinking that the persisted session wasn't updated since I didn't do a submit and so when the page was requested, it behaved as it should, but not what I had in mind. THUS...I believe I need to submit the page and prevent the auto-dml and page branching afterwards....but how? I feel that I am missing something very fundamental here and that the answer may also help me with other related questions:
* How does the confirm delete examples work? How is the processing stopped when the user presses cancel?
* How can you do validations and stop dml processing without losing the user values?
* How can you display and error page and then return to where the user was with the values still present?
* How can I do a secondary sql value lookup based on the users selection in a popup lov? (User selects a Database/DbID - then I want to lookup host using DbId)
I haven't been successful understanding this from the manuals, but someone can point me to some material that explains submit processing, redirects, etc. I would be happy to do some more digging.
Thanks greatly in advance.

Thanks Scott,
I may be being dumb here but I don't see how that would help...
P250_PROJECT and G_PROJECT are currently kept in sync by app logic. Whichever is used to drive, if the page is rendered from cache then the app logic is not executed, so the rendered page contents are not those keyed by P250_PROJECT, as illustrated in steps 1-4 of the problem above.
The user sees X, the session items say Y. The engine doesn't know what the user is seeing.
when page P is POSTed, its hidden item P250_PROJECT should always be used to derive the application item G_PROJECT. Then whether the page was pulled from cache or rendered anew via a click from the sidebar link, the project ID is determined by the contents of that page.
As I said above I tried this, with the 'Edit' branch set to:
Set these items: G_PROJECT
With these values: &P250_PROJECT.
but it makes no difference. The project ID is not determined by the rendered page contents - the engine gets the value of P250_PROJECT from session state.
I can code the 'Edit' pages such that they check permissions and if necessary redirect back to p250 (conditional before-header branch), but that's a clunky cure rather than the prevention I was hoping for.
Please tell me if my understanding is incorrect.

Format Mask in Session state

In a Summary Region (Page 6) I have changed one field to text, edited the field with no format mask. In the entry form on the pervious page, the column properties are Database Column, and Always replace value in Session State with the Money format Mask.(Page 5).
10313 5 P5_LPP Text $66.67 LPP
10313 6 P6_ENGAGER_LPP Text Field $66.67 I
Question is that the field in field 6 displays the value $66.67. Why not 66.67?
On Page 6 a user can press the Update_lpp button and Invalid Number Error Page pops up?
Is there a way to hold in the session state the values only while formatting on the screen is $'
Thanks

Thanks. I did an "on submit and before computation" process that did a SQL replace on the page item. The DML process then successfully inserted the value into the database.

Items session State from form to another ...

Hi Guys,

I have been trying to pass items session state from one page to another page using branch , but to no avail.
Can you please have a look...

Application 64941 - Modal Page
On the setting of Skillbuilders Dynamic action, I used this Static URL:

Hi Trent,
Actually, i did not create new DML. and my problem is not with the source.
in a nutshell,
the items on the first page have source of Static assignment .. only one item has a default value
the items on the second page have source of Database Column .. none of the items have default value
1- What caused the confusion is:
We run the page 1 , we have an item (Mobile) with a default value ( that means it has a session state value by default ) > Concur.
I type a value on the second item ( Mobile 2) then set session values.
both items ( Mobile & Mobile 2 ) have session state values. > Concur.
Click Modal Page button to trigger the modal page. where the Static URL is:
f?p=&APP_ID.:2:&APP_SESSION.:::2:P2_MOBILE,P2_MOBILE2,P2_MOBILE3:&P1_MOBILE.,&P1_MOBILE2.,&P1_MOBILE3.We see that only the value of the first item (P1_Mobile) goes to the modal page. but rest of the items do not go.
I hope that it is clearer now..
Best Regards,
Fateh
If you want details, Please allow me to tell my scenario. I have two forms "Clients", "Inquiries".
As a client calls, I need to identify whether the client is exit on the DB or not.
So, as the client calls, we enter the mobile phone number into items that have static assignment source, then click on a button to check if the client details are already on the DB. if yes, the inquiry form shows up. if No, a modal page (that have clients form) pops up to allow inserting the details of the client in items that have Database Column Source . but since we have already inserted the mobile number in the the first step.. I do not want to insert them again in the client form.

Fateh

Saving session state in database table rather in websever for Ordering App

Hi all,
Ours is a ordering application (telecomm) domain.
Currently, we are storing user sessions data (Order shopping cart session data) in middle tier (iPlanet web server) which inturn consumes lot of memory resources.
Shopping cart could be in MBs if order is a huge business order.
So in order to not to overtax web server (middle tier), we are thinking of storing session data directly in a database table to relieve the overhead on web server and make use of database for storage.
I read that APEX (html db) is already using this "single metadata table" approach for session data management. But we are not using HTML DB to really look into.
Can some one advise how to go about storing "user session data" directly in a "database table" for both storage and retrieval purposes instead of storing it in "webserver".
How does this "metadata table" structure looks like. Is it more generic ?
Really appreciate your time and help/suggestions.

Joel,
Thanks for your response. sorry, i meant to say that "the current application does not use APEX but will look into it".
To build this is an utterly non-trivial exercise. Oh - it may not be so hard to save session state to a table when you POST a page. But you may want to reference this in many places, and it's a question of can you change all of these references to indirect references from session state in your application.In order to free up the load on webserver, we want to maintain session management in database. Could you please explain the above little more :
How do we maintain the "user session" with "database table" ?
Do we need to store "session data" at java object level or by page in database table ? How does the structure of this "metadata table" looks like.
Thanks for your time.

Session state is not being passed properly to another page

Hello Gurus,
I have a multi-page application which authenticates using a simple authentication page 101. Right now I have a generic authentication scheme which always returns true (Session Verify Function= return true; I will integrate LDAP later.) It works fine. The app remembers the username from one page to the next (popup pages mainly).
My issue is that, after exporting the application and re-importing into a new workspace, the user/session state is no longer being preserved from page to page. It prompts for a login every new page that is opened (the popups). This ruins the flow and functionality of the app.
I've checked every setting (I think) and cannot find any differences between the two workspaces or apps. Any ideas why this would work in one workspace and not the other?
TIA!
Jonathan
I should also indicate that the issue seems to be specifically in calling "callmypopup" function. For some reason it isn't passing the session id properly to the popup page, where it did fine in the other workspace. function text:
function callMyPopup (sourceItem, popuppagenum, targetItem, appid, appsession) {
//opens popup pg and passes value in sourceItem to targetItem
//sourceitem=calling text box, targetItem=text box in popup page
var minlength = 3;
if (CheckLength(sourceItem, minlength))
var formVal1 = document.getElementById(sourceItem).value.toUpperCase();
var url;
url = 'f?p=' + appid + ':' + popuppagenum + ':' + appsession + '::::' + targetItem + ':' + formVal1;
w = open(url,"winLov","Scrollbars=1,resizable=1,width=800,height=600");
if (w.opener == null)
w.opener = self;
w.focus();
else {alert('Please enter at least ' + minlength + ' characters in your search.');}

It looks like your session id is not correctly passed to your popup page. Try using:
javascript:popUp2('f?p=&APP_ID.:1:&SESSION.:::::', 600, 700);
instead, which does the same thing. Put your parameters for the page items there if required.

Problem with application item and session state

Okay, let's see if I can explain this problem coherently.
I have a small app (one page), with an application item, F_WHERE_CLAUSE.
This page has three regions in which there are items that the users can populate for search conditions. A couple of these items are "select list with submit" (I still need to upgrade to the AJAX method, I know). There is another region which has one hidden field, called P1_WHERE_CLAUSE. This field is defined to "Always, replacing any value in session state..." with source type of "Item (application or page.....", and a source value of F_WHERE_CLAUSE with no default value.
I have a button called "Search" which submits the page and fires a PL/SQL process which builds a where condition based upon the other page items and stores the value to the application item F_WHERE_CLAUSE (correctly).
For testing, I've made the P1_WHERE_CLAUSE field visible so that I can see what's going on. I've also clicked the debug and session buttons to help trace this. After I click the "Search" button and the page submits, debug shows:
0.02: ...Session State: Save "P1_WHERE_CLAUSE" - saving same value: "1=1"
followed later by:
0.05: ...Session State: Saved Item "F_WHERE_CLAUSE" New Value="lower(primary_class) = 'rock' and country = 'Spain'"
The field P1_WHERE_CLAUSE displays with the correct search criteria as signified by F_WHERE_CLAUSE above. However, If I click the "session" button to view the session state values, P1_WHERE_CLAUSE shows up as:
P1_WHERE_CLAUSE Textarea 1=1 U while F_WHERE_CLAUSE displays the correct value still.
The reason this "problem" came up, is that this page also has three SQL report regions which use &P1_WHERE_CLAUSE. for the where condition. While they display the correct results on-screen, each report region also has the "Export to csv" enabled, and the export seems to be using the "1=1" condition (from the "session" window) instead of the search criteria that the on-screen region is using (F_WHERE_CLAUSE and the displayed P1_WHERE_CLAUSE), resulting in a retreival of all records.
Anybody have any idea what's going on and why, and how to get the csv export to use the correct value for the where condition?
Thanks,
Bill Ferguson

It appears the "Export to CSV" functionality requires the item value to be set in session state. The P1_WHERE_CLAUSE item value never gets saved to session state. The page is rendered and the value is put in the item on the page but until you submit the page session state doesn't know what P1_WHERE_CLAUSE is.
Create a before header computation or process to set the value of P1_WHERE_CLAUSE (which will save it to session state). It is interesting that the report regions didn't need to look at the value in session state but the "export to csv" does.

Is there a way to add a checksum to this? OR does anyone have any ideas on how to work around this?

WORKAROUND:
1.) Create hidden ITEM on page (I named it P23_PREPARED_CSV_DOWNLOAD_URL).
Enter the following for the ITEM
as the SOURCE_TYPE : PL/SQL Function Body
as the SOURCE: return apex_util.prepare_url('f?p=&APP_ID.:&APP_PAGE_ID.:&APP_SESSION.:CSV:')
2.) Create BUTTON that executes javascript to open POPUP window with this url.
a.) Create Button and enter
<a href="javascript:popupURL('&P23_PREPARED_CSV_DOWNLOAD_URL.')">Download and Save to CSV file</a>as the "Text Label/Alt"
Originally had custom code for javascript POPUP and this is not needed .... just use the APEX javascript function.

How to update session state from form field values without submitting page?

Hi,
I am new to Oracle APEX. I am using Oracle Apex 4.2 on Oracle 11g release 2. The problem is that when I am entering data on a form, when I enter a value in one field and move to the next field, how can I use the value of first field in the validation procedure of next field? I know that when we enter data in fields, the session state is not updated with these values until we submit the page... right... but I have seen that if there is a control of List box type, then Apex gives an option "Action When List changes" where we can choose option to update corresponding session state field with the value of list box item, without submitting the page.
Now my questions is why this option is only available for List box items? why not for other item types like Text box, Check box,... ? can someone please help me with this?
(the issue with update of session state depending on page submitting, is that we need a complete network round trip from client to server in order for it. However if we can update session state variables without submitting page, then we can avoid this network traffic).
Any help will be greatly appreciated. Thanks in advance.

Create a dynamic action on change and run a PL/SQL process there with the following code:
BEGIN
NULL;
END;Page items to submit > your item.
This will set the session state without submitting the form.

Session State in Report Queries

Hi all,
I've got a report query with XML Structure set to advanced. I added two items to session state - a "department name", and a "current date" - these are application items that I want to put in the page header of my report template.
After I load the XML data and go to insert a field, I see some session info available for inserting (appl id, user, report title, etc.) along with my report fields, but I don't see the two session items I added. I took a look at the XML data and they're not there.
How do I get the session items to be included with the XML?
Thanks!!!

Sorry, I should have mentioned I am using a BI Publisher RTF Layout for my report layout, therefore I don't believe I can use it on apex.oracle.com. If BI Publisher is in fact installed there, then please correct me.
I am including session variables with the report, but the session variables between all of the report queries in my application are common between report queries. (Even though I really only want variables specific to each report to be included) When I add or delete a session variable from one report query, it affects all report queries in my application. This could be a feature, but I doubt it since it does not seem intuitive.
In addition, sometimes a random session variable or set of session variables will disappear from the list. (this is what I meant by drop) I cannot seem to determine when/what triggers this action, but it seems like this may occur when I delete a particular report query.
I can try to put up an example on apex.oracle.com, but I'm not sure if this is dependent on the presence of BI Publisher.
Thanks in advance for any help!
