Commit/rollback impact

Hi!
what is the impact of commit/rollback even without any changes since the last commit/rollback? Is it made the request to the logwr write from the redo buffer to the redo log file?
Thanks a lot

How to avoid the Commit/Rollback dialog box

I've a JClient app with two frames wich relate to the same appllication module with the same connection (I need it because I want a single commit).
I start the first frame,then I click a button to start the second frame, I insert data in the second one and I see the commit/rollback buttons in both navebars enabled.
When I close the secod frame, without committing (because I want to commit at the end of the whole process) I receive the Commit/Rollback dialog box.
How can I solve that problem ?
TIA
Tullio

Remove or conditionalize the code in generated Form/Frame.java class that binds a WindowListener to the Frame like:
    addWindowListener(new WindowAdapter()
        public void windowClosing(WindowEvent e)
          _popupTransactionDialog();
          JUApplication juApp = panelBinding.getApplication();
          if (juApp != null)
            juApp.release();
          System.exit(0);
}You may either conditionlize the above windowClosing method or the code in generated method
private void _popupTransactionDialog()

Commit/Rollback in Stored Procedures

I'm just confused about how this setup works. I understand that ODP.NET is in autocommit mode by default, and any INSERT, UPDATE, or DELETE commands are committed automatically. If they fail for any reason, obviously the row(s) are not modified.
But how about sprocs? Do they autocommit as well? If so how are rollbacks handled? Do I need to explicitly create a transaction and commit/rollback? Is it best practice to commit/rollback in the .NET transaction or in the sproc itself?
As you can see, I'm just really looking for info on how these two interact. Any info you can provide will be extremely helpful.
Thanks!

Hello,
When ODP.NET is operating in auto-commit mode (the default as you note) this applies to PL/SQL calls as well.
I am of the opinion that the client should be in charge of a transaction and I do not commit/rollback inside PL/SQL code (unless of course I am writing PL/SQL that is the client of other PL/SQL code).
Here's a bit from Tom Kyte on the subject:
http://tkyte.blogspot.com/2007/03/dreaded-others-then-null-strikes-again.html
Just search for the text "Who control the commit?" on that page.

Commit/Rollback on Tab pages

I have three tab pages
1st tab page called master_detal_page. It is base block bound to tables.
2nd tab page called Keyword_page. It is not bound to the table.
3rd tab page called Exit_page. It will popup dialog box ask for save the changes. commit,rollback,exit_form on trigger when-page-change.
I encountered problems that I was unabled ROLLBACK or COMMIT the change I made on 1st or 2nd pages. When I refresh tab pages always display back to orginal records.
Please help me with any technical to solve it. Thanks
Trigger: WHEN-TAB-PAGE-CHANGED
DECLARE
v_result VARCHAR2(30);
BEGIN
IF :SYSTEM.TAB_NEW_PAGE= 'EXIT_PAGE' THEN
v_result := FUNCTION_DISPLAY_MSG_BOX('Do you want to
save changes before existing');
IF v_result = 'YES' THEN
COMMIT;
GO_BLOCK('BLK_1ST_PAGE');
ELSIF v_result = 'NO' THEN
ROLLBACK;
GO_BLOCK('BLK_1ST_PAGE');
ELSE
EXIT_FORM(NO_VALIDATE);
END IF;
END;

what is the error you got? go to menu/display error to see if any.
Then it likely you got saving issue with your master-detail block.
can you save with only master block data? but cannot save if both blocks have new data?
if yes, then you may add when-validate-record trigger to master and detail blocks, with code forms_ddl('post');
then see it makes difference.

Commit/Rollback Buttons Diabled for Pinned Tables?

When I pin a table, the commit/rollback buttons become disabled. Is there a reason for that, or is it a bug?
Java(TM) Platform 1.5.0_12
Oracle IDE 1.5.0.52.03

Finally got some time to let it return. 454 tables takes takes between 9-10 min. I also noticed if I cancel it, SQLDeveloper becomes pretty unresponsive....probably for the remaining 9-10 minutes, but I've been too busy to double check.
As for the Commit/Rollback buttons becoming disabled in 1.5.0, I'm not able to get an exact sequence, it "just seems to start happening". It happens when I have multiple tables pinned. Changes to one will let me commit/rollback, but changes to another will not. The window with the disabled commit/rollback buttons sometimes will not even mark a rownum as changed if it has been updated.
The refresh button still prompts you to save since changes were made. That works as a commit/rollback if the buttons are disabled.

TimesTen doesn't commit/rollback executed DMLs in procedure, so tables were locked.

Hello, when PLSQL_TIMEOUT occured, TimesTen doesn't commit/rollback executed DMLs in procedure, so tables were locked.
Please help. How can I solve this problem?

Looks like I've a mistake, not PLSQL_TIMOUT, after ODBC connection timeot it seems doesn't commit/rollback.
java.sql.SQLException: [TimesTen][TimesTen 11.2.1.8.0 CLIENT]Communication link failure. System call select() failed with OS error 110. This operation has Timed Out. Try increasing your ODBC timeout attribute or check to make sure the target TimesTen Server is running
Also I couldn't find why locked and what locked. My procedure waiting for lock or something I dont know, so timout occured

Establishing commit-rollback mechanism in a transaction

Hi,
If there are more than one tables that records to be inserted into and more then one record for some tables, is it possible to establish commit rollback mechanism?
It must be used repeater action for some tables because of more than one records to be inserted.
I'm trying to establish commit rollback mechanism for all inserts for oracle database.
Is it possible?
Thanks.

Hi,
with the standard SQLQuery it is not possible. Sam has develop some custom action blocks with this
functionality. Take a look on this link [Installing the SAP MII v12.1 JTA JDBC Custom Action Blocks.|http://www.sdn.sap.com/irj/scn/index?rid=/library/uuid/10bfa608-103b-2c10-6399-e41044c3363e]

Commit / RollBack

Hi,
I want to execute 2 or more database operation in one transcation with commit/rollback mechanism.
Below is my code,
How can i make it has commit /rollback (in one transaction).
Thanks.
InitialContext ctx = new InitialContext();
DataSource ds = (DataSource) ctx.lookup("jdbc/SAPXXXDB");
Connection con1 = ds.getConnection();
Connection con2 = ds.getConnection();
PreparedStatement pstm1 =con1.prepareStatement("insert into ZTABLE1(...)Values(...)";
PreparedStatement pstm2 =con2.prepareStatement("insert into ZTABLE2(...)Values(...)";
pstm1.executeUpdate();
pstm2.executeUpdate();
con1.close();
con2.close();

Hi Cemil Bozlagan ,
When a connection is created, it is in auto-commit mode. This means that each individual SQL statement is treated as a transaction and is automatically committed right after it is executed.
The way to allow two or more statements to be grouped into a transaction is to disable auto-commit mode by using Connection object.
con.setAutoCommit(false);
Once auto-commit mode is disabled, no query statements are committed until you call the method commit explicitly. All statements executed after the previous call to the method commit are included in the current transaction and committed together as a unit.
Have a look
PreparedStatement pstm1 =con1.prepareStatement("insert into ZTABLE1(...)Values(...)";
PreparedStatement pstm2 =con2.prepareStatement("insert into ZTABLE2(...)Values(...)";
pstm1.executeUpdate();
pstm2.executeUpdate();
con.commit();
con.setAutoCommit(true);
To roll back the transaction based on ur requirement u can use
con.rollback()

In background job how commit & rollback work works?

Hello Friends,
My requirement is, to fetch all sales order items based on some condition and load them into one table say OCC1 in job J1. Now the second requirement is to upload the job information J1 with job name, user name, end date in second table say OCC2 in job J2.
My question is if there is some error I found while processing job 2 I have to rollback entire work which means I have to remove all records those I have inserted in to table OCC1. Can any one suggest me how to handle such problem? Some how I am able to create two job and update the tables. However, what about rollback work? Whether there is an implicit commit work after every background job? I am working on SAP 4.6C version.
Thanks,
Amol C.

I think by using just ROLL BACK work it will not rollback your first job's data.
You need to make some mechanism which can delete the data from OCC1 if the J2 got error.

I think the problem is that you are using a database that does not support transactions.

Implement commit,rollback,cancel popup when swapping task in dynamic region

Hello,
I have been trying to implement this functionality when I swap task flows in a dynamic region....
A popup/dialog to be displayed with the following options (assuming there are changes to be saved on the task flow being swapped out)
Commit - save the changes on the the outgoing task flow and continue to bring in the new task flow
Rollback - cancel the changes on the the outgoing task flow and continue to bring in the new task flow
Cancel - remain on the outgoing task flow and do not bring in the new task flow
If i click on a button within the outgoing task flow, it is possible to determine the condition of the view object, determine if there are pending changes and display such a dialog, the problem is if that the navigation within the dynamic region is being performed from outside the region, we are advised against using task flow return activities when using bounded task flows within regions ( section 17.1.8 of fusion dev guide for 11.1.1.1.0 ) so the only thing i can think of is building a finalizer routine for the task flow. While this does get executed when the task flow is swapped out... how can i display the dialog from there, and stop execution of the finalizer and return to the original task flow if ultimately i want to cancel.
Any ideas? other solutions?
Thanks.

Thanks for the reply Richard,
I think this will probably be an important feature for anyone using the single page model, unless that model is not being encouraged/being discouraged. Unfortunately I'm not aware of the "How-to" you mentioned, but I would dearly LOVE to be. The project I am working on is in a relatively early stage, and this would be the time to put things in extension libraries, templates and the like. Especially if there is no official line on when a formal fix might be available, the plans not being firm and all...
But thanks for the reply none the less... I'd still appreciate any further information if anyone has some form of solution.
Cheers

Commit Rollback for Parent & Child table

Hi,
I need to load data to a parent table and child table (Record by Record), i.e one record will be loaded to the parent table and the related child record will be loaded to child table.
After first record loaded to child table, the next record will be loaded to the parent table.
My requirement is, I should not commit the parent table before the child record is transferred (so that i can rollback if my record got failed). So I have set the parent table IKM commit option to NO. Because of this, my child record is not loaded to the correcsponding target table, its failed because the parent record is not commited.
Do we have any possiblities to overcome this issue.
Thanks in Advance,
Ram Mohan T

Cezar,
I couldn't make the CKM options to "No Commit". When i did that i am getting the following error at step "16 - Control - CUSTOMER_DET - insert PK errors" ,
12838 : 72000 : java.sql.SQLException: ORA-12838: cannot read/modify an object after modifying it in parallel.
This error occurs at the CKM. so i have made all the CKM options to "commit" and IKM, LKM to "No Commit". It seems to be fine.
Cezar,
I have some plan for the scenario that i mentioned in the previous update (One dept id and all related employees). Please verify this,
1) create a procedure which extracts dept_id from source tab and passes it to the scenario(in target tab) of a package.
2) This package has the variable of dept_id, interface1 which loads data to dept and following that another procedure(2).
3) This procedure2 will extract the emp_id that corresponds to the value of the variable dept_id. And passes this emp_id to tha scenario in target tab.
4) This scenario is of a package which has the emp_id variable and interface2 for loading employees.
While executing this plan, the problem is,
1) Interface1 which loads Dept_Id is not commited (due to the KMs with commit set to "No Commit"), so that the employee records are getting loaded to the error table.
2) I have made the interface1 KM commit option to "Default: Yes " (But still the Knowledge modules steps are No commit), but still the child records are getting loaded to error table.
3) As per the above scenario, all these transforamtions are not taking in the same transaction. Thats the problem i believe.
Do we have any possiblities to overcome this Cezar?
Thanks in Advance,
Ram Mohan T

Commit & Rollback in procedure.

Hi All,
I am Using ODI 11.6 and Oracle 11 g.
I have a senario
where i have Int_1--->Procedure 1--------->Int_2
The int_1 will update Table_1
If the procedure_1 is succesfully runs then it updates Tab_2
Suppose the Int_2 will fail which will update the Tab_3
I need to rollback the Tab_2 and Tab_1.
How to do this in ODI?
So we have any kind of Commit option in Procedure?
Thanks,
Lony

Interface 1 & 2 should use KMs which runs DDL and DML operations is separate transction.
For your info , most of the shiped KM do this . Just verify the same once again
Once the above is done then note the DML operation is happening in which transtion . Say it is happening in transction1.
Set commit to no for INT_1
Create your procedure and set commit to no commit
In the procedure set the transction to the same as that ok INT_1 IKM ( say transction1)
INT_2 set commit to yes

JDBC adapter Commit/Rollback

Hi Guys, I got a question regarding JDBC adapter auto commit. Hopefully you guys can help me :). Until now, when my XI calling a storedprocedure in ORACLE using JDBC adapter, it will automatically commit the calling. When i see my configuration for the JDBC adapter receiver, the checkbox for Enable Autocommit is thicked. My question is, is there anyway that we handle the commit or rollback ourself. How we can handle that? Is it from the BPM or just from the Configuration.
Thank you very much in advance for all replies, advices and answer. Cheers guys..

Hi
Try this out
You can programmatically set auto commit to true as in follows
// Load the Oracle JDBC driver
DriverManager.registerDriver(new oracle.jdbc.OracleDriver());
// Connect to the database
// You can put a database hostname after the @ sign in the connection URL.
Connection conn =
DriverManager.getConnection ("jdbc:oracle:oci:@", "scott", "tiger");
// It's faster when auto commit is off
<b>conn.setAutoCommit (true); </b>
// Create a Statement
Statement stmt = conn.createStatement ();

Parent Table - Child Form(bounded task region)- Commit-Rollback Button's

Hello,
Here's my simple scenario:
Jdev 11.1.1.2
One Am(datacontrol).
One vertical panel splitter
On top A panel collection with a read-only table(employees VO), The table lists just a few of the attributes, so it's really just for browsing, and a toolbar with createinsert, commit and rollback button's.
At bottom: A PanelTab with a bounded task flow - region. The child region(bounded task flow) contains an editable ADF form(same VO) will all attributes available for editing. The form(child region) also contains a 'submit' button (to post changes).
When run the page commit and rollback button are disable. (ok)
Navigation and sincronize between table and task flow works fine because i set partialtrigger. (ok)
When i change some attribute in the form and then press summit button, I want the commit and rollback button's became active..
. . any help would be much appreciated.

Hi Bart,
if your bounded task flow is placed in .jspx using region it is possible to reach binding container of that task flow.
You can use handies by Edwin Biemond:
# // main jsf page
# DCBindingContainer dc = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
# // taskflow binding
# DCTaskFlowBinding tf = (DCTaskFlowBinding)dc.findExecutableBinding("dynamicRegion1");
# // pagedef of a page fragment
# JUFormBinding form = (JUFormBinding) tf.findExecutableBinding("regions_employee_regionPageDef");
# // handle to binding container of the region.
# DCBindingContainer dcRegion   = form; but ExecuteWithParam works for me in bounded task flow - I think you have mistake in your NDValue="#{pageFlowScope.pclNummer}". you should use $ instead #
regards,
Branislav
