Change Data Capture (CDC) for Oracle by Attunity on SQL Server 2014

hi
i've installed the above on my server. It seems to look fine. The connection to oracle database is set, the databases on the sql server side have been created; the tables to be captured are created. When i make a change on the oracle side, the configuration
ui senses the change, but no data is moved over. Silly question, do i have to move the data from oracle to sql server FIRST before any of this will work? and how do inserts work if the data has to be moved over to sql server first? I'm missing something here
Any help would be appreciated.
thank you

Well, better ask the vender. They haver their own forums.

Changed Data Capture (CDC) when view as a Source

Hello All,
We implemented Changed Data Capture (CDC) by taking table as a source and we used to JKM Oracle Simple KM and it is working fine. But, we need to implement CDC by taking View as a source. Included Primary key at ODI Level for this view as CDC requires this on the source.
As we cannot create triggers on views and also while creating journal view prefixed with JV${table_name}, getting the following errror:
"1446 : 72000 : java.sql.SQLException: ORA-01446: cannot select ROWID from view with DISTINCT, GROUP BY, etc."
How can we achieve CDC if our source is a view?
Any suggestions..
Thanks,
-Vency

Hi,
Its not issue of a "lock" so no luck..
Its definitely the issue with the view..
I also got the real error as:
ORA-012024:Cannot select FOR UPDATE from view with DISTINCT,GROUP by etc..
Wonder why this is the error, as my view does not have DISTINCT,GROUP By etc..
Also checked
select * from USER_UPDATABLE_COLUMNS ;
and found that none of the columns are updateable..
So how to make these updateable and get my form work?

Distributed Hotlog Change Data Capture (CDC) on 10.2.0.3 - Very Urgent

Hello all,
I am trying to set up distributed Hotlog Change Data Capture (CDC) with both source and staging databases on 10.2.0.3. I have managed to set up everything alright until I try to great my first change table on the staging database.
We tried runnning this:
begin
     dbms_cdc_publish.create_change_table(
          owner => 'CDC_STG9_PUB',
          change_table_name => 'ed_test_1_CT',
          change_set_name => 'CR_FN9_SET',
          source_schema => 'CIS',
          source_table => 'ed_cdc_test_1',
          column_type_list => 'col1 number, col2 varchar2(20)',
          capture_values => 'both',
          rs_id => 'y',
          row_id => 'n',
          user_id => 'n',
          timestamp => 'n',
          object_id => 'n',
          source_colmap => 'n',
          target_colmap => 'y',
          options_string => null) ;
end ;
I sometimes get this:
begin
ERROR at line 1:
ORA-00942: table or view does not exist
ORA-06512: at "SYS.DBMS_CDC_PUBLISH", line 611
ORA-06512: at line 2
Re-running the create change set seems to solve this.
However, when I try to run enable the change source, I get this:
begin
ERROR at line 1:
ORA-31532: cannot enable change source CR_FN9_SRC
ORA-06512: at "SYS.DBMS_CDC_IPUBLISH", line 151
ORA-06512: at "SYS.DBMS_CDC_PUBLISH", line 497
ORA-06512: at line 2
Any ideas would be very well appreciated.

Change Data Capture (CDC) - Best Approach

Hi,
I am new to BODI and currently trying to design a change data capture approach.
In other ETL tools i have used, the last session run timestamp is stored as a parameter and can be called within a mapping. So the mapping updates this parameter everytime it runs. Therefore when implementing CDC the load_date on the table has to be compared to this parameter.
Is there a similar concept in BODI?
I appreciate your help.
Thanks
Azeem

Yes, there is such a concept, you have to build it yourself. e.g. https://wiki.sdn.sap.com:443/wiki/display/BOBJ/Inititialize-End+Script
When you use a CDC enabled datastore however, the database wants to keep track of the data read, that's part of their CDC API. So it is not DI is querying all changes since yesterday, it is a "select * from CDC table" and the database returns just the rows since the last read. Push vs. Pull.

Bug in SQL Server 2008 R2 for Change Data Capture (CDC)

I'm pretty sure I've encountered a bug in SQL Server 2008 R2 that's been fixed in 2012, regarding changing the design of a database using CDC. With CDC disabled on a table with sys.sp_cdc_disable_table, I can add a column or change a column's data
type, but when I call sp_rename, on 2008 R2 I'm getting "Cannot alter column 'xxx' because it is 'REPLICATED'.", even though the table's properties shows "Table is replicated" as False. In 2012, works fine.
Even calling sys.sp_cdc_disable_db didn't prevent this error.

Change Data Capture (CDC) now capturing default values

Hi,
I am using SQL Server 2012 and to me a part of data captured by CDC is not making sense.
I have a table called 'Schema.Table1', and I enabled CDC on it by running 'sys.sp_cdc_enable_table'. I see that a table called 'cdc.Schema_Table1_CT' got created which now gets an entry when ever I Insert, Update or delete a record in the original table.
Till this point every thing works fine.
My original Table has a NOT NULL INT column called 'AuditTrackerUserID' with a default value of 1996. My application does not provides a value for this column, but because the column itself has a default value, records get inserted without error.
When I try to execute the following Query I see multiple records with __$operation of 3 and 1.
SELECT * from cdc.Schema_Table1_CT where AuditTrackerUserID IS NULL
My expectation is that I should not ever see any record returned by this query because AuditTrackerUserID is a not null column, but I do.
Can anyone please explain this behavior>

ODBC errors for Oracle Migration Workbench and SQL Server 2000 on Windows

Hi all-
I setup a new ODBC connection for the Oracle 10g Migration Workbench to MS SQL Server 2000 on Windows XP and keep getting the following errors when I try to
either test the new ODBC connection to MS SQL Server 2000 for use with the Oracle Migration Workbench tool. Goal is to fix these errors so that I can migrate our test SQL Server 2000 databases to Oracle 10g.
Current configuration
- Oracle 10.1 Migration Workbench
- Oracle 10g Database (target)
- MS SQL Server 2000 (source database)
-Windows XP
-ODBC 3.85.1117 driver for Windows XP with SQL Server and Oracle
Errors:
I. When I test the ODBC connection:
Microsoft SQL Server ODBC Driver Version 03.85.1117
Running connectivity tests...
Attempting connection
[Microsoft][ODBC SQL Server Driver][TCP/IP Sockets]Specified SQL server not found.
TESTS FAILED!
Now here is what has me totally confused:
I can use the command line ISQL to access the database on the server and IP is all correct and port is available. So I can access the SQL Server database fine it is when I try to setup ODBC that it gives me problems.
Any tips how to get this ODBC working?
Thanks
Ben Prusinski

1. Jing Jin. If you had READ the post you would have seen that installing later versions is NOT an option.
2. Not supported does NOT mean does NOT work, as Balmukund pointed out in the referenced thread. The site that this databases supports is using ASP which is also NOT supported by Microsoft. As it turns out Balmukund's solution actually turns
out to be the correct solution. I installed SS2K and its Service pack 4 on the machine last night. Good answer Balmukund. as we say in the Navy, "BRAVO ZULU!!" which means "WELL DONE!!
3. Tom Li I just posted the question less than 48 hours ago. My last post was less than 24 hours ago. I think I have the right to be given the opportunity to determine whether a reply is the answer or not. I understand you don't like unanswered
posts sitting around for weeks, months or years. (I don't like it either as I have a few that are still unanswered after several years.) But you should not be showing replies as answers before I even get a chance to see them, much less try them out.
You should also not be showing replies as answers which don't address the criteria of the question. I specifically stated that I had to install SS2K. I went on to state, "And before anyone asks I need to install this version because that is what
the customer is using and I need to duplicate their databases." So the correct answer, if in fact SS2K did not work on Windows 7, would have been a virtual machine answer, as suggested on the thread Balmukund referenced. So before you mark a reply
as an answer read the question.

Change Data Capture (CDC)

Hi All,
I have been trying to do a CDC on a table. I do the selective reverse on the table and after it is imported, I add it to CDC and than when I start CDC, I encounter the following error. I tried it with different tables and its the same error.

Please help me with suggestions. I know, I am doing a mistake somewhere.
Thanks in advance.

SSIS Pattern for CDC for Oracle

I am in the process of implementing the CDC for Oracle product from Attunity, and I have a good understanding of how the CDC process works from Oracle to SQL Server. The next step is to load the changes into our operational data store.
Does anyone know of good patterns in SSIS for handling the initial and ongoing loads for CDC for Oracle? I have SSIS packages that handle pure SQL Server CDC, so I understand that process. However, I'm not sure if there are special
things that need to be done to mark the end of the initial load and then start loading changes into the operational data store. Are there any gotchas I need to keep in mind when working with Oracle data and the CDC changes
in SQL Server? My main concerns are with data consistency between the Oracle system and our operational data store, once the initial load is finished, CDC is started and we copy data to the operational data store. What are good patterns
to ensure I'm not missing data, and that I don't introduce duplicate records, because of timing.
Any advice is appreciated.

If you are using the CDC for Oracle that Microsoft OEMs from Attunity:
Change Data Capture Service for Oracle by Attunity
CDC for Oracle in SQL Server 2012
It populates the change data in a SQL Server database, just like SQL Server CDC would. So the built-in SSIS support for SQL Server CDC will work.
Change Data Capture (SSIS)
One difference is that the current table data is not available in the SQL database; only the change data is. So to do a full init, or reinit of a table you would have to load that data directly from Oracle.

Change Data Capture: Unsubscribed column results in new change set record

I have an installation using Oracle 11g Change Data Capture in synchronous mode. As of writing, I have a single publication and a single subscription. The setup is pretty basic:
PUB_TABLE
PUB_ID*
PUB_NAME*
PUB_USELESS_FLAG
* columns are included in both the PUBLICATION and the SUBSCRIPTION. The final column is of no consequence and is excluded from both the PUBLICATION and SUBSCRIPTION.
My problem is that any time PUB_USELESS_FLAG gets updated (even if no other columns are changed), a record is written to not only the change table but the change table view. The table in question has a significant number of transactions logged against it, but only a subset of those changes are of note to the subscriber (which is why the subscriber does not listen to every column). However, since the subscription is receiving records for every change to the source table, the result is an enormous amount of overhead as the subscriber is forced to sift through numerous records that are of no consequence.
I read the Change Data Capture manual for Oracle 11g; I could not find any reference to the observed functionality. Is this a consequence of using synchronous vs. asynchronous modes of capture? Is there an option to only receive changes on subscribed columns?
Thanks in advance

Bring this to the top because I have the same question. This website (http://www.bikinfo.com/HTML/CDC/CDC_Article.html) makes it sound like this problem is unavoidable.

Can CDC (Change Data Capture) Can be used for Audit / Trail Purposes

Hi,
My question is bit subjective in nature. I playing around with CDC to implement a Database Auditing solution and it's seems to be working fine. However my question is for experts and for those who have already used CDC for this purpose. Is it feasible to
use it for Data Auditing? Has anybody successfully used it? Any important considerations or configurations you have worked out e.g. CDC cleanup time etc
I will highly appreciate any feed back.
Thanks,

Change Data Capture in ODI

Hi all,
A client of ours is planning to replicate their production database into a reporting database. All tables will be copied to the reporting DB. They also need to do "Change Data Capture" on the production DB and reflect the changes into the reporting DB in real time. Since the production DB is from a transaction system, the changes will be quite big. They are worried about the performance of the production DB during the copy process. Is Oracle Data Integrator capable in doing this? They are running Oracle 9.2 on Windows platform. Thank you.
Regards,
Gerd

Gerd
ODI's main Changed Data Capture (CDC) functionality for the Oracle database is implemented using the LogMiner functionality provided by the database. When used in asynchronous mode, this imposes a minimal overhead on the source database, as the transactional system is not "interfered" with by the log capture process.
During the copy process, ODI will simply be reading a view (a join across the table containing the primary key (or unique identifier) and the original data) which should be very efficient. The load is minimal. It is being used very successfully by clients in this way.
