Data Change Capture

How do I capture only changed data in Oracle database.?
Thanks

Chumkayz,
This can be achieved with the help of Oracle Change Data Capture at the following levels:
01 - Table Differentiation
02 - Value based or Time-stamped
03 - Cost propotionality
You can refer to the following documentations (depending on your DB version) for further understanding of CDC:

Config/Control data change capture

Hi,
I want to replicate any data changes made to the config/control data of SPRO to a non-SAP system. Would there be user exits or change pointers for these transactions? How can I confirm this? If this is not possible then what options are available SAP?
Eagerly awaiting a response..
Thanks in advance

Capturing data changes in alv using classes

Hello All,
Currently am working on alv report using classes..,In this report am displaying 3 grids in the output in 3 different containers(cl_gui_custom_container)...,Am able to handle the data changes done in the grid at the run time using event data_changed ...,
Now the requirement + problem is ...if i do the changes in all the grids ,,,,,and if i click(hotspot event) on any of the rows/records in any of the grids ...,, I need to be able to capture all the data changes done in all the other grids....,,
for example:-
if i modify some records in all the 3 grids ,,, and if I click any of the row in any of the grid at a time,,, all the changes done in all the grids should be captured.....( in simple words one click all changes )
I tried using data_changed event....., am only able to capture the changes of the grid on which i clicked ( ie.hotspot event) but not the changes which i have done on other grids.....Pls. help me out with the possibilities
Hope am clear..
Thanks

Hi friend,
METHOD handle_user_command.
CASE e_ucomm.
WHEN 'UPDATE'.
             CALL METHOD r_grid->get_selected_rows
          IMPORTING
             ET_INDEX_ROWS =
             et_row_no     = it_rows.
LOOP AT it_rows INTO wa_rows.
*****modify the first container data***********
endloop.
CALL METHOD r_grid1->get_selected_rows
          IMPORTING
             ET_INDEX_ROWS =
             et_row_no     = it_rows1.
LOOP AT it_rows1 INTO wa_rows1.
*****modify the second container data***********
endloop.
CALL METHOD r_grid1->get_selected_rows
          IMPORTING
             ET_INDEX_ROWS =
             et_row_no     = it_rows2.
LOOP AT it_rows2 INTO wa_rows2.
*****modify the third container data***********
endloop.
endcase.
Now we can create three container and three different grid class object but we are using same method.
UPDATE buttton is common to all three containers.
But one important point when u change the records in container we must select the rows then only selected rows r come to the internal table otherwise it is not come.
CREATE OBJECT r_container
    EXPORTING
      container_name              = 'CONTAINER_1'
CREATE OBJECT r_container2
    EXPORTING
      container_name              = 'CONTAINER_2'
CREATE OBJECT r_container3
    EXPORTING
      container_name              = 'CONTAINER_3'
CREATE OBJECT r_grid
    EXPORTING
      i_parent          = r_container
CREATE OBJECT r_grid1
    EXPORTING
      i_parent          = r_container2
CREATE OBJECT r_grid2
    EXPORTING
      i_parent          = r_container3
NOW WE CAN CALL THE METHOD.
CREATE OBJECT event_receiver1.
SET HANDLER event_receiver1->handle_before_user_command FOR r_grid.
CREATE OBJECT event_receiver1.
SET HANDLER event_receiver1->handle_before_user_command FOR r_grid2.
CREATE OBJECT event_receiver1.
SET HANDLER event_receiver1->handle_before_user_command FOR r_grid3
I thing it should be possible.But u must remeber u must select the records when u modifie in three containersBUT UPDATE button is common to all three containers.

Capture date change event of Time Refresh Control

Hi,
Is there any possible way by which we can capture the date change event from the time refresh control of iGrid?

Hi,
Ok lets do it this way.
I have a page in which i am having radio button for date selection say YTD, MTD and so.
In the page i have a frame in which an iGrid is coming up with some data based on the time period selected on the page.
Now if i change the date from the time refresh control of the iGrid in the frame i want to uncheck the radio button seleted on the page as now its not YTD or MTD or whatever selected previously.
Is there any possible way to do this?

Can I change image date and capture year in Aperture?

Is there a way to manually change the image date and capture year (and other metadata for that matter) upon import? I have some pictures given to me by friends that they took on their own cameras and I want to import them into my Aperture Library, only it seems as though they didn't pay attention to/care about setting the date/time on their cameras. This causes me to lose sequence with my own photos that were taken with my camera on the same day.
I tried to append and replace the IPTC Metadata, but that didn't seem to work. What can be done about this, or am I just stuck with some out of sequence photos when I sort by image date?

RB,
That worked perfectly, and was just what I was looking to do. Thanks.

How to change capture date to unknown in Lightroom 5.2

How do I simply change a photo capture date to unknown in Lr 5.2? I scanned some photos that somehow automatically got the scanned date input as capture date and I need to reset it to unknown. I've spent way too much time searching for an answer for such a simple task. Any help would be appreciated.
Thanks,
Brian

LR doesn't provide a feature to change capture date to unknown, nor does it allow plugins to do it correctly. You'll have to use an external tool (e.g. the free Exiftool) to modify the metadata of the photos directly:
1. If you've added keywords, captions, or other metadata to the photos in your catalog, or you have applied Develop settings, then in LR, select all the affected photos and do Metadata > Save Metadata To File.
2. Use Exiftool to remove the fields EXIF:DateTimeOriginal, XMP:DateCreated, and IPTC:DateCreated and :TimeCreated.
3. Select all the photos and do Metadata > Read Metatadata From File.
The Capture Time To Exif plugin may make step 2 a little easier for you, though you'll have to figure the Exiftool command line arguments yourself.

How does Sybase Replication Server capture data changes?

Hello,
as far as I know Sybase Replication Server is a central component in a HANA-based enviroment when it comes to replicate data towards HANA engine.
I scan briefly through a white paper of Sybase, but I gives no technical description how the Sybase Replication Server captures data change on the source database.
Can someone gives here explanation?
All the best,
Guido

Hello Marc,
thanks for fair and hornest answer!
I'm currently involved in SAP based project where we are migrated business on DB level, which is some kind of operation a heart. I personally have huge respect for this approach.
Caputring the changes on DB level is a appoarch, but I personally think that you need to capture event on business object level. For exammple the SAP good old workflow knows events for business objects. Also in a ESA-driven application you should have some kind on eventing for business objects.
For the time being the current approach might working for a kind of Proof-of-Concept,
but on a mid and long-term based you need to RETHINK!
All the best & Merry Christmas & Happy new year

Capture data changes to Control Data

Hi,
I want to replicate any data changes made to the config/control data of SPRO to a non-SAP system. Would there be user exits or change pointers for these transactions? How can I confirm this? If this is not possible then what options are available in SAP ECC?
Eagerly awaiting a response..
Thanks in advance

Dear folk,
In SAP we have two tables CDPOS and CDHDR for the changed data to be maintained.
CDHDR-Header data
CDPOS-Item data.
Based on ur requirement , u can check these tables by giving the table name and field name.
to the appropriate fields in the CDHDRa nd CDPOS.
Revert if u need any help regarding this.

How can I recover from a Botched BATCH DATE CHANGE in iPhoto?

Botched Batch Date Change iPhoto08
Short Story: Intending to change the date for one photo I managed to change the dates for all 8,525 images in my iPhoto08 library to the SAME DATE!! I found that the original creation dates were saved in the in the Modified field that appears in the Photo Info Window / File metadata subsection. I would like some help figuring out how to set the Date Created to this File Modified Date that appears in the Photo Info Window.
GORY DETAILS:
I used iPhoto08/ Photos menu / BATCH CHANGE... /“Set DATE to 20100723 1:20:54 PM” with “Modify original files” checked. iPhoto changed all 8,525 images to the same date.
I now realize I should have used Photos menu / Adjust Date and Time ... But the damage was already done. Unfortunately there was no Edit menu / Undo for this operation. ALL 8,525 images have the same date. I checked in the the iPhoto Information sidebar--same date all images.
Next, as a test, I dragged an image to the desktop and opened it in Graphic Converter7.0.3. The same date “20100723 1:20:54 PM” appeared in the Image Browser List /”Date Created”, “Date Modified”, “Date Captured” metadata fields.
The following appeared in the Graphic Converter
Image Preview sidebar (subWindow) going left to right
Image menu/button
Date and Time: Friday, July 23, 2010 1:20:54 PM PT
Exif menu/button
File date and time: 2010:07:23 13:20:54

<<<<<<OH MY GOD >>>>>> the BATCH CHANGE / SET DATE not only RESET the date for EVERY IMAGE in my library, it also changed the date metadata EVERYWHERE inside each individual image file.
Actually it's my Mom and Dad's iPhoto library containing all the kids and grand kids pictures, family trips, important events, everything. There is no backup. I feel as if I have tipped over a file cabinet containing all our photos. Our “date and event” organized 8,525 image iPhoto library was now as useful as a giant shoebox. On second thought, a shoe box full of real photo prints would be more useful than my iPhoto library because the prints would have the print date stamped on them.
At this point feeling desperate I closed my eyes and said a quick prayer to Saint Rita - Patron Saint of the Impossible.
I returned to iPhoto .................and noticed the Show Photo Info MENU item in the Photo Menu.
I selected it.
And Low and behold,
in the Photo Info WINDOW,
under the Meta data File SUBSECTION, the correct photo creation date appeared -->" Modified: 20071002 05:46:07 PM" I checked different photos ... They all had different FILE MODIFIED dates. These dates were/are the old creation dates! My prayers were answered: THANK YOU SAINT RITA!
But now I am really stumped! This File Modified Date seems to be some kind of external metadata that is indexed or keyed to each image. How is this metadata stored in the iPhoto library? How can I access this File Modified date? I now turn to you GREAT iPhoto WIZARDS. Pray tell, how can I set the “Creation Date to the file Modified Date” that appears in the Photo Info Window as a (scriptable?) batch process.
I am on my knees for this one...please help. we have iphoto11 but afraid to upgrade to it. until i know more i don't want to loose this Modified Date metadata.

thanks for the quick response...
no simple solution because no backup to restore from
iPhoto seems to be using file metadata as some sort of index key in the
Photo Info Window. open up the iphoto library package and take a look at
the .xml file -- ModDate is used everywhere. hoping to export this data and merge/join it to
each image.
still trying to figure it out.
thanks,
Tom

How to schedule the webi report based on data changes in the report data

Hello,
I want to schedule a webi report based on data change in a column in the report.
The scenario is something like below:
1. If a data of a particular column changes from 2 to 3 than I would like to schedule this report and sent it to users mail box.
I know how to apply alerts or schedule a report or data tracking for capturing changes in the report but I dont know how to schedule the report only for data changes.
Anybody done this before.
Thanks

SQL Server data change and Security

in our environ any user who login with sa they can change any table data.
so i write trigger to capture changed data like who change, from which IP etc this
CREATE TRIGGER [TRG_Users]
ON [dbo].[UserRights] AFTER INSERT, UPDATE, DELETE
AS
DECLARE @strIP VARCHAR(MAX)
SET @strIP=(SELECT dbo.GetCurrentIP())
IF EXISTS (SELECT * FROM INSERTED) AND EXISTS (SELECT * FROM DELETED)
--PRINT 'Update happened';
INSERT INTO Logger(IPAddress,Status)
VALUES (@strIP,'UPDATE')
ELSE
IF EXISTS (SELECT * FROM INSERTED)
--PRINT 'Insert happened';
INSERT INTO Logger(IPAddress,Status)
VALUES (@strIP,'INSERT')
ELSE
--PRINT 'Delete happened';
INSERT INTO Logger(IPAddress,Status)
VALUES (@strIP,'DELETE')
CREATE FUNCTION [dbo].[GetCurrentIP] ()
RETURNS varchar(255)
AS
BEGIN
DECLARE @IP_Address varchar(255);
SELECT @IP_Address = client_net_address
FROM sys.dm_exec_connections
WHERE Session_id = @@SPID;
Return @IP_Address;
END
but the problem is user can change data after disabling the trigger on specific table. so trigger will not fire and user can seamlessly change data.
so guide me what is the best way to capture data change and log them. so no one can bypass the security. please do not tell me disable sa account because i am looking for different approach to capture the change data. is there any secure way exist in sql
server 2005/2008 if yes then please discuss here. thanks

If you have shared SA password with different users you are bound to get these scenarios.Instaed of focussing on how to capture I would like you to talk with different users and only provide them access which is required.Follow policy f minimum privilege
your environement will be less complex .
You can use combination of Logon trigger and CDC to capture it.But again why o make things complex by sharing SA password with many users.

Problem with change capture

HI,
we've a problem with the Change Capture in the DAC's Execution Plan.
We've cretead a new data model but we want to reuse the image table and the Change Capture process, so we've perfomed the following step:
1) create the mapping SDE e SIL for the new tables of datamodel in Informatica Power Center
2) register these mapping in the DAC
3) create a subject areas and associate these tasks to this
4) create execution plan including "change capture" and "change capture sync"
5) execute our "execution plan"
the problem is the following:
from the Execute -> Current Run Tab -> task
we can see that execution time of change capture is 0
from the Execute -> Current Run Tab -> task details
there aren't any change capture details
So, our image table are empty.
Do you have any idea?
Thanks in advance,
Antonello.

HI Antonello,
I am also having the same issue like you. I have created a new execution plan in DAC 101341 and ran it. It seems like the task Change Capture For Siebel OLTP completed in 0 seconds and there are no details for that particular task. Can you please let me know if you have resolved this issue? Your help is much appreciated.
Thanks

Change Capture For Siebel OLTP task in DAC running for more than 10 hours

whole etl load used to complete in 2 hours (as on now siebel data having sample data). since last Friday Change Capture For Siebel OLTP task in DAC execution plan running for more than 10 hours. I am not able to trouble shoot the problem because no log for this task
what could be the reason for this problem? how can I fix that problem?
Appreciate your help
Thanks
Jay.

Which ETL is it that is taking the longest (is it an SDE, SIL, PLP?). I have seen someOracle vanilla ETLs coded in a way that is very ineffective. Check the DAC and Informatica logs and find out which mapping it is and where the delay is (e.g. SQL, write to DB..etc).

Batch date change problem in iPhoto

I have hundreds of printed photos I scanned in 2009. Even though they were taken over three decades iPhoto thinks they were all taken in 2009. I separated them into years, numbered them, and put them in folders which became events. I tried using batch date change -- the first one in the event is OK, but the others changed all different. Example: I changed picture one, in event folder "1999" from 3/5/2009 to 1/1/1999. All of the rest of the pictures changed to the same time difference that they were when I scanned them. I didn't scan them all in chronological order, so that doesn't help at all. Do I have to manually change each of my 9000 photos? This is a problem when I try to show a chronological slide show on Apple TV.

Scanned photos do not have an EXIF Capture Date field in the file like photos taken with a digital camera do. Therefore iPhoto uses the file created date or import date for those photos.
You will have to group all 1999 photos into an album, arrange them in the order you want and then use the Photos ➙ Batch Change ➙ Date menu option and add a 1 minute or so between photos.
Then do the same for the next year's photos.

Delta data changes are not reflecting from ODS to another infocube

ODS1 --->Infocube1 - Field1,field2,field3
ODS2 -
> Infocube 2 -
Field 2-1,2-2,2-3,field2-4
Both datasource information are totally different.
Delta changes are captured in the field3 in ODS1 and Infocube 1 also.
Field3 and Field 2-3 is the same field .Infocube 2 - I have included infoobject and populating the value from ODS1-Field3.
The question is
Whenever I capture the changes from ODS1-field3 -the similar changes also needs to be updated here in infocube2 -field2- 3.
Start routine : I have created code like ,
SELECT field1 field2 field3
INTO CORRESPONDING FIELDS OF TABLE IT_field
FROM /BIC/aods1.
Update rule routine : Select the field2-3 in the characteristic- routine
READ TABLE IT_field INTO LS_field
WITH TABLE KEY
field1 = COMM_STRUCTURE-field2-1
Field 2 = COMM_STRUCTURE-field2-2.
Result = LS_field -field2-3.
If I load the full load to infocube 2 -no problem.
Is their any other way Can I capture the transactional data changes in infocube 2.
Advance thanks

Thanks for quick update. You are right.
There is no problem from ODS1 --->Infocube1 - Delta is working properly.
My question is ,
ODS1 has a field 3. Whenever new changes happen for this field3 - I have to capture the simialr changes in the Infocube 2 and the fieldis 2-3.
field3 and field 2-3 is the same field infoobject .
Whenever the changes occurs inthe tranasation - ODS1-field 3 will capture the changes. How can I capture the similar changes in Infocube 2 and the field 2-3.
