CDC - How to configure when to insert changed data in Change Tables

Hi!
I have the following situation: I need to capture changes from some source tables only when some columns of interest changed, not when any data from those tables changed.
Is there a way to confidure that in CDC? I use Synchronous Publishing.
Thank you in advance!

What you can do is set up CDC to record both the before (UO) en after (UN) image of the updated row and then filter out the rows that have different before and after values for the columns that you want to check on.
See e.g. http://download.oracle.com/docs/cd/B19306_01/server.102/b14223/cdc.htm#i1025616, step 4, capture_values=>both. You can even delete rows from the change table directly, before consuming the change set result from the subscriber view.
Best regards, Erik Ykema

in dreamweaver mx 2004 and dreamweaver cs4, how I configure, when download/upload do not ask me to include DEPENDED FILES but act without including ?

Open the Preferences panel (Edit menu on Windows, Dreamweaver menu on a Mac), and select the Site category. There are two checkboxes there for dependent files. Make sure both are selected. The Dreamweaver default is NOT to upload/download dependent files. You need to click Yes, if you want the dependent files to be included.

Hello,
What manu suggested this can be done through oracle forms.
If as i read your last post you are using that in database it will not work in db. Try to use the same process in oracle forms will work by making some changes.
And if you don't want to use forms then there is one way using SQL LOADER. It required control file to execute for uploading data.
See the below link.
http://www.orafaq.com/wiki/SQL*Loader_FAQ
In this example its showing filename.csv you can use your file name like yourfilename.txt.
So your control file will look like this...
load data
infile 'file_path\file_name.txt'
into table table_name -- use actual table name where you want to upload data
fields terminated by " " -- Here using spaces as you mentioned
(column1, column2, column3) -- Here use the three column names of tableAnd after creating control file with the above code. You can call it in command prompt like this
sqlldr username/password control=control_file_path\control_file_name.ctl log=log_file_path\log_file_name.log
or
sqlldr username/password@dbconnection control=control_file_path\control_file_name.ctl log=log_file_path\log_file_name.log
Before doing this practice make sure SQLLDR.exe availabe in the machine where you have to execute. Otherwise you will have to install db client for using sqlldr.exe

Can i change or modify or insert the data in standard tables

hi gurus
can i change /modify/insert the data in standard tables
witout using module pools
plz send the progem lines also
it ll be very helpful to me
thank you
kals.

Hi Kalyan,
It is not advisable to update standard tables directly or through your own module pool programs also. The reasons are,
1. It is difficult to find out how many tables are updated through the transaction. if we leave one table also as Mr.Andrew said data integrity will be lost.
2. Authorization objects and profiles will be totally bypassed if data is inserted through custom programs.
3. Complete data validation is not possible. There are certain validations that are executed through code and appropriate errors and warnings are shown in the transactions. If we insert data directly to the tables anything can be inserted into the table field violating all the validations unless we have field level check constraints on the tables at database level.
4. User Exits and BADIs that are implemented for specific business requirements and checks will not function on the data.
5. Update & Transaction locks will not work properly.
Due to above reasons, definitely you should avoid updating standard tables directly.
There are many tools such as LSMW Recordings, BDCs, BAPIs, IDOCs, Upload Interfaces available in SAP through which bulk data can be updated without using relevant transactions.
You can collect data from end users in text or excel sheets or through custom programs in required format and upload at once through above mentioned tools.

When I insert new data on an existing graph, the graph deletes

When I insert new data on an existing graph (for example, just adding a new year of data) and press insert, it just deletes the graph entirely. My only option is to recreate the entire graph which is frustrating because I lose its format and colors. Any suggestions?

Here I opened the existing chart, with the old data. I need to remove the oldest year and add a new year. Which I do below:
When I press the check mark, or enter, the graph details all delete.

How to insert the data system created table throuch RFC

Hello Chandan
It is pure madness to update or modify tables like MARC or T100W directly, whether on remote systems or locally.
If you need to update or modify such tables on remote system search for the appropriate <b>BAPI </b>(e.g. in case of MARC use BAPI_MATERIAL_SAVEDATA).

Do I have to use lock when I am reading data from a table

Hi,
When i am reading data from a table , do I have to set a lock on that table .
Is it necessary for us to set the lock on a table when I am reading data from the table.
When I am updating the table , do I have to set a lock on the table ?
If yes, then what sort of lock-read lock,write lock or shared lock?
Regards,
Sushanth H.S.

check it out,
Lock objects are use in SAP to avoid the inconsistancy at the time of data is being insert/change into database.
SAP Provide three type of Lock objects.
- Read Lock(Shared Locked)
protects read access to an object. The read lock allows other transactions read access but not write access to
the locked area of the table
- Write Lock(exclusive lock)
protects write access to an object. The write lock allows other transactions neither read nor write access to
the locked area of the table.
- Enhanced write lock (exclusive lock without cumulating)
works like a write lock except that the enhanced write lock also protects from further accesses from the
same transaction.
You can create a lock on a object of SAP thorugh transaction SE11 and enter any meaningful name start with EZ Example EZTEST_LOCK.
Use: you can see in almost all transaction when you are open an object in Change mode SAP could not allow to any other user to open the same object in change mode.
Example: in HR when we are enter a personal number in master data maintainance screen SAP can't allow to any other user to use same personal number for changes.
Technicaly:
When you create a lock object System automatically creat two function module.
1. ENQUEUE_<Lockobject name>. to insert the object in a queue.
2. DEQUEUE_<Lockobject name>. To remove the object is being queued through above FM.
You have to use these function module in your program.
check this link for example.
http://help.sap.com/saphelp_nw04s/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
tables:vbak.
call function 'ENQUEUE_EZLOCK3'
exporting
mode_vbak = 'E'
mandt = sy-mandt
vbeln = vbak-vbeln
X_VBELN = ' '
_SCOPE = '2'
_WAIT = ' '
_COLLECT = ' '
EXCEPTIONS
FOREIGN_LOCK = 1
SYSTEM_FAILURE = 2
OTHERS = 3
if sy-subrc 0.
MESSAGE ID SY-MSGID TYPE SY-MSGTY NUMBER SY-MSGNO
WITH SY-MSGV1 SY-MSGV2 SY-MSGV3 SY-MSGV4.
endif.
Normally ABAPers will create the Lock objects, because we know when to lock and how to lock and where to lock the Object then after completing our updations we unlock the Objects in the Tables
http://help.sap.com/saphelp_nw04s/helpdata/en/cf/21eea5446011d189700000e8322d00/content.htm
purpose: If multiple user try to access a database object, inconsistency may occer. To avoid that inconsistency and to let multiple user give the accessibility of the database objects the locking mechanism is used.
Steps: first we create a loc object in se11 . Suppose for a table mara. It will create two functional module.:
1. enque_lockobject
1. deque_lockobject
before updating any table first we lock the table by calling enque_lockobject fm and then after updating we release the lock by deque_lockobject.
Select the radio button "Lock object"..
Give the name starts with EZ or EY..
Example: EYTEST
Press Create button..
Give the short description..
Example: Lock object for table ZTABLE..
In the tables tab..Give the table name..
Example: ZTABLE
Save and generate..
Your lock object is now created..You can see the LOCK MODULES..
In the menu ..GOTO -> LOCK MODULES..There you can see the ENQUEUE and DEQUEUE function

Insertion of data between 2 tables ( 1 to * relationship )

Hi all, I am new to Oracle ADF, I have a problem with the insertion of data between 2 tables (Table A and Table B), I have the ratio 1 to *, and I need to insert data in table B (* Relationship) when insert in Table A all goes well, but when inserted in Table B, I need the primary key value in Table A () in the value field in table B that is as foreign key.
Ie
Value Table A
coda = 20 -> primary key
Table B values
1 set of values
val_1,
val_2,
val_3,
coda = 20 -> need this value is constant up to do a Commit.
set of values 2
val_1,
val_2,
val_3,
coda = 20 -> need this value is constant up to do a Commit.
How I can do it?
thanks

Thanks for you answers 'M.Jabr'
I was wrong, because the relationship 1 to * between tables A and B, I was writing the groovy expression in each table, in this case in Table B (A.codSolicitude), but now I notice that within the DataControls, but specifically in the control data of Table A, there is a relationship between the board B, and I thought to insert into the related table that appears as a master/detail, and first inset in table A and then in Table B in the same page master/detail, and A.CodSolicitude value is automatically filled in Table B, and performed the Commit and everything works. !
Thanks for you help.
Now if you can give me some examples with images that are on the web similar to this problem would be great:) Thanks!

Insert the data into two tables at a time.

Hi ,
i have these two tables
create table [dbo].[test1](
[test1_id] [int] identity(1,1) primary key,
[test2_id] [int] not null
create table [dbo].[test2](
[test2_id] [int] identity(1,1) primary key,
[test1_id] [int] not null
alter table [dbo].[test1]
add constraint [fk_test1_test2_id] foreign key([test2_id])
references [dbo].[test2] ([test2_id])
alter table [dbo].[test2] add constraint [fk_test2_test2_id] foreign key([test1_id])
references [dbo].[test1] ([test1_id])
I want to insert the data into two tables in one insert statement. How can i do this using T-SQL ?
Thanks in advance.

You can INSERT into both tables within one Transaction but not in one statement. By the way, you would need to alter your dbo.Test1 table to allow null for first INSERT test2_id column
See sample code below:
CREATE TABLE #test1(test1_ID INT IDENTITY(1,1),test2_id INT NULL)
CREATE TABLE #test2(test2_ID INT IDENTITY(1,1),test1_ID INT)
DECLARE @Test1dentity INT
DECLARE @Test2dentity INT
BEGIN TRAN
-- Insert NULL as test2_ID value is unknown
INSERT INTO #test1(test2_ID)
SELECT NULL;
-- get inserted identity value
SET @Test1dentity = SCOPE_IDENTITY();
INSERT INTO #test2(test1_ID)
SELECT @Test1dentity;
-- get inserted identity value
SET @Test2dentity = SCOPE_IDENTITY();
-- Update test1 table
UPDATE #test1
SET test2_ID = @Test2dentity
WHERE test1_ID = @Test1dentity;
COMMIT
SELECT * FROM #test1;
SELECT * FROM #test2;
-- Drop temp tables
IF OBJECT_ID('tempdb..#test1') IS NOT NULL
BEGIN
DROP TABLE #test1
END
IF OBJECT_ID('tempdb..#test2') IS NOT NULL
BEGIN
DROP TABLE #test2
END

How to configure drop-down that change dynamically in Call Scripts

Hi,
Would like to know as how to configure drop-down choices that change dynamically based on customer response in Call Scripts / Assessment Scripts of type "Service Request - Survey".
I've read the following from CRM OnDemand pdf but was not able to figure out how to do that.
Call Scripting:
• Reduces agent training time
• Provides drop-down choices that change dynamically based on customer response
• Supports personalized interactions based on existing record data
• Facilitates up-selling and cross-selling
• Does not require third-party software
I don't have a concrete requirement as of now, but was trying to check as how it works. Please guide me if any one has implemented the same.
Thanks in Advance,
Cheers!!!
Deepak Veeravalli.

Arun,
If you plan to implement the "Querying the Active Directory" based on my code snippet,
and if you do not have permission [your account must be the part of domain admin] to do so,
Then still you can do it in least effort through code,
string usersInXml = SPContext.Current.Web.AllUsers.Xml;your xml string look like this.
<Users><User ID="2" Sid="" Name="Administrator"
LoginName="i:0#.w|murugesan\administrator" Email="" Notes="" IsSiteAdmin="True" IsDomainGroup="False" Flags="0" /><User ID="1" Sid="" Name="Murugesa Pandian" LoginName="i:0#.w|murugesan\murugesan" Email="" Notes="" IsSiteAdmin="True" IsDomainGroup="False" Flags="0" /><User ID="1073741823" Sid="S-1-0-0" Name="System Account" LoginName="SHAREPOINT\system" Email="" Notes="" IsSiteAdmin="False" IsDomainGroup="False" Flags="0" /></Users>
You can user Linq to XML to filter the "LoginName,Name and Email and then populate your drop down list.
* User must be logged into the site at least once.

CDC - How to automatically notify subscribers about change?

I'm planning to use Oracle Change Data Capture mechanism, but I need to implement automatic data propagation - after the change in source system occurs.
As I understand for now, in order to apply changes in target system using staging change sets I have to run some kind of periodical jobs which will purge old data, extend the window and apply new data.
The problem is that, I don't want to run periodical jobs, I I'd like to run the procedure loading change data using change sets as soon, as change in source system occurs. This could be (theoretically) done by defining some trigger on change table - but this is probably impossible.
So there is my question, do you know any possible solutions for my problem?

How about Oracle Golden Gate? I could read that it can be easily integrated with Oracle Data Integrator. Would it solve my problem?

What's the exact trigger for when updating/inserting/deleting data from one DB to another DB which contains same info?

Hi guys,
I have created a copy of the AdventureWorks2012 DB called AdventureWorks2012_new on the same instance.
I have created the following trigger below but my friend who is a DBA told me that this is not correct and I should be using the inserted table when creating this trigger. I would like AdventureWorks2012_new DB to be updating/inserting/deleting data from
the same tables that have been updated/inserted/deleted in the AdventureWorks2012 DB. How exactly should I do this for all the tables in the whole database ? What I have written below is just for one of the tables, is there a quicker way to do it for all tables
in this DB so that it performs the actions mentioned above, automatically ? Help would be greatly appreciated so I can understand how this works, thanks
CREATE TRIGGER [HumanResources].[tr_HumanResources_AfterUpdate]
ON [AdventureWorks2012].[HumanResources].[Department]
AFTER UPDATE
AS
BEGIN
SET NOCOUNT ON;
UPDATE AdventureWorks2012_new.HumanResources.Department
SET Name = t2.Name,
GroupName = t2.GroupName,
ModifiedDate = t2.ModifiedDate
FROM AdventureWorks2012.HumanResources.Department AS t2
INNER JOIN AdventureWorks2012_new.HumanResources.Department AS t1
ON t2.DepartmentID = t1.DepartmentID
END

For insert it's easy:
CREATE TRIGGER [HumanResources].[tr_HumanResources_AfterInsert]
ON [AdventureWorks2012].[HumanResources].[Department]
AFTER INSERT
AS
BEGIN
SET NOCOUNT ON;
Insert INTO AdventureWorks2012_new.HumanResources.Department
(DepartmentID, Name, GroupName, ModifiedDate)
SELECT DepartmentID, Name, GroupName, ModifiedDate
FROM Inserted;
END
I didn't verify column names, so you may need to make sure to use correct column names for that table.
