Granularity of change rules in CDC (using Oracle streams) at columns level.

Is it possible to implement granularity of change rules in CDC (using Oracle streams) at columns level.
E.g. table abc with columns a1, b1, c1 where c1 is some kind of auditing column. I want to use CDC on table abc but want to ignore changes on c1.
Is it possible? My other option is to split table abc into a child table that has the Primary key and c1 only but it needs additional table and joins.
Thanks
Shyam

The requirement can be implemented by a simple trigger.

Capture Changes from Sql Server using Oracle Streams - Destination Oracle

Is it possible to capture changes made to tables in Sql Server database and propagate the changes to Oracle Database using Oracle Streams and Heterogeneous Gateway. I see plenty of information about pushing data from Oracle to Sql server, but I haven't been able to find much information about going the other way. Currently we are using sql server 2005 replication to accomplish this. We are looking into the possibility of replacing it with streams.

the brief understanding i have is that there is nothing out of the tin that Oracle provides to stream between SQL Server and Oracle. The senario is documented in Oracle docs however and says you need to implement the SQL Server side to grabe changes and submit to Oracle stream queues.
i'm sure i've seen third parties who sell software to do this.
If you know otherwise please let me know. Also wasn;t aware one could push from SQL Server to Oracle. Is this something only avail in SQL Server 2005 or does 200 also have it? How are you doing this?
Cheers

Problem changing default key bindings using Oracle Terminal

Hello,
I'm facing a problem changing default key bindings using Oracle Terminal. I changed
some bindings, saved them in forms60/fmrusw.res, started the generation and saved again.
I thought that's it but it wasn't. It took no effect at all in Forms (even after recompilation) although reopening the file in Terminal showed the changes. I'm using Forms in German, which means that even the key bindings displayed in Forms are translated i.e. STRG+F1 instead if CTRL+F1,
but I can't find a german version of this resource file, so i think it's the same resource file for all supported languages. But what is needed for the changes to take effect ?
Thanks in advance

Hi,
is it client/server you are working?
if so you should not be using the fmrusw.res file because I guess your NLS_LANG is German_Germany.WE8ISO8859P1 or something like that. This means the terminal that is being opened is fmrdw.res instead of fmrusw.res and this file should be edited using Oracle Terminal.
if you are working via the web implementation than you can open the file fmrweb.res in a text editor and change the keybindings in there. If you need to have the PC like key bindings on the web just open the fmrpcweb.res and see if it contains the German texts. If so you can either copy this file over the frmweb.res file or you can specify term=fmrpcweb.res in the serverargs parameter.
Hope this helps.
Kind regards,

Replication selective columns using oracle streams

Hi
I am basically replacing an mview by streams.
At source I have about 45 columns in a table. But at target I just need to replicate 7 columns. I am wondering if there is a way to configure streams such that a list of column is passed.
I know there are rule-based transformation available DBMS_STREAMS_ADM.DELETE_COLUMN. But wondering if there is an easy way to do it with out writing transformations for each column.
Thanks
N

Yes the major reasons to move from mview's are
- add column, delete column requires complete refresh of mviews at target, which runs for hours
- Any structural changes to table at source requires the entire application to be down as the source table very active. And so Cannot afford a down time to add , delete columns at source, so we use OTR (Online table redefinition) to do so, and OTR cannot be performed on tables that have mviews based on them.
Oracle Support recommended using Oracle Streams, but it also has its limitations with very few workaround available.
I know for streams too there is a limitation of OTR, but we can reinstantiate table after the otr is performed on the source , with add_column or delete_column transformations., and get the transformation going from where it stopped. ( Avoiding complete recreating of table at Target).

RESETLOGS using Oracle Streams

Hi all,
I have lost my all my redo log files, i need to open the database and i think that i will need to use RESETLOGS option. I'm using Oracle Streams, do you think that if i use RESETLOGS the Streams will work fine after that???
Tks,
Paulo.

Yes, it is. You may read my article (Note Id: 431430.1) on metalink, it address a similar issue.

XML queries... Change the code from using Oracle db into MS SQL

Hi, I am a new begginer in this field. I came accross to an article that focuses in Oracle's XSU approach.
Currently, i am trying to convert the java code from using Oracle db to MSSQL db. The code has shown below:
import javax.naming.*;
import javax.sql.*;
import java.sql.*;
import oracle.xml.sql.query.*;
public class testxml
     public static void main(String args[]) throws SQLException, NamingException
     String tabName = "emp";
     int maxRows = 3;
     Context ctx = new InitialContext ();
     DataSource ds = (DataSource) ctx.lookup ("MyOra");
     Connection conn = ds.getConnection ();
OracleXMLQuery qu = new OracleXMLQuery (
conn, "select EMPNO, ENAME from " + tabName);
qu.setMaxRows (maxRows);
qu.setRowsetTag ("EMPLOYERS");
qu.setRowTag ("PERSON");
String xmlString = qu.getXMLString();
System.out.println (xmlString);
conn.close ();
Currently, i am having difficulties to change the "bold" area that uses Oracle into MS SQL as my current application is using MS SQL as the database.
Please help and need more advices from all of you. Thank You

I resolved this issue myself. For the answer please message me.

Hot backup while using oracle streams

Hi All,
Stream replication is enabled for some tables in two way .for both DML and DDL operations ...
Now we are process of taking the hotbackup of the database.
Will the Alter tablespace begin backup will effect anything
or do we have to add dbms_streams_adm.set_tag.
And what else we need to add for the capture process or need to write some negative global rule for capture process.
If anybody is using the streams and running hotbackup ,please Share the example ..
Thanks In Advance for your reply ASAP

If you use RMAN to do the hotbackup, you do not need to do "Alter tablespace begin backup" (assumes your database is in archivelog mode)

How to change value in database using oracle form

- i have a table called mobilephone with quantity column
- i already created a list of quantity inside my form with elements 1-5
- what i want is when i press a button inside my form it will automatically deduct the value i chose from list to the database
- for example if my quantity inside the table is 10, when i chose 2 in the list it will become 8 in the table

Hi,
I agree with Roel, but it might not be enough for you. This depends on the usage, and more specifically the number of concurrent users that might do the same kind of transactions.
If user1 has selected 5 phones, and at the same time user2 has selected 6 phones, then only at the moment they hit the "Apply Changes" or "Create" button, will they know whether they the number of phones they require are actually available.
If this scenario is highly unlikely to occur, I would go with the trigger as Roel indicated. If it is likely to occur, you might want to consider using Javascript to immediately check the availability through a database function call. This will require some database changes, that I could elaborate on. But I will wait until you indicate that this is indeed what you need.
Good Luck!

How do I change the examples to use Oracle rather than Cloudscape

I set up the JDBC connector and can ping my Oracle DB from WebLogic. I know what
to run the first EJB example using the Entity beans and persisting with the CMP.
I built a table in Oracle - just don't know the process for talking to Oracle
rather than to Cloudscape which seems to start automatically with the Examples
server. I have the JDBC code, but where do I put it? What config files need to
be modified?
Thanks!

Is there anyway of creatiing a different name for this Folder rather than 2013?
If you are using one of Lightroom's "date-based" folder templates, then the folders are created in accordance with the image capture date, not the date that you happen to import it. If you specifically want to use the import date for your folder names then you probably don't want to use the Lightroom date template, and instead you'll need to setup your folder names manually.
The vast majority of users that use date-based folder naming schemes will use a standard Lightroom template, i.e. based on the much more meaningful image capture date.

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.

Significance of Global_names parameter in Oracle CDC and Oracle Streams

Hi,
I am trying to implement a sample Oracle CDC example.
I read in some examples that we need to set a parameter *'global_names= TRUE'*. (which means that all dblink names should be same as their respective database names)
But my doubt is that what will happen if i use the default value 'FALSE' for this parameter without changing it to 'TRUE'.
Is it mandatory to make 'global_names= TRUE' ?
Could anyone please explain this.
Thanks in Advance
Regards,
Gowreesh.

Hi Sybrand,
Thanks for the reply.
Currently there are some dblinks in my database(with dblink names different from the database).
My concern is,
If i make global_names=TRUE, then all my earlier dblinks with that database will not work.
and if I DONOT make global_names= TRUE, then i will not be able to work with Oracle CDC/Streams with the database.
I am looking to find out any work around to overcome this deadlock type of situation.
I would be very thankful if you can give some idea to come out of this problem.
Regards,
Gowreesh

Can I use Oracle Stream from 10.2 to 10.1?

I need to stream data from Oracle 10.2 --> 10.1.
I'm not sure any concern?
Can I do it, right?

Yes, you can do it.
Just remember to configure rules that discard incompatible changes (i.e. things that are supported in 10.2 but won't work in 10.1 should not be replicated).

Oracle Streams - Apply Rules

I want to replicate two tables (A, B) using Oracle Streams from one database to another database using Oracle Streams. One column in table A contains salary information for Hourly employees and salaried employees. I do not want to replicate the salary information for salaried employees in the target system. Is there any way that I can set the salary to null for salaried employees at the same time applying any other changes to the table in the target database?
Any advise is appreciated.

Oracle Streams 'ORA-25215: user_data type and queue type do not match'

I am trying replication between two databases (10.2.0.3) using Oracle Streams.
I have followed the instructions at http://www.oracle.com/technology/oramag/oracle/04-nov/o64streams.html
The main steps are:
1. Set up ARCHIVELOG mode.
2. Set up the Streams administrator.
3. Set initialization parameters.
4. Create a database link.
5. Set up source and destination queues.
6. Set up supplemental logging at the source database.
7. Configure the capture process at the source database.
8. Configure the propagation process.
9. Create the destination table.
10. Grant object privileges.
11. Set the instantiation system change number (SCN).
12. Configure the apply process at the destination database.
13. Start the capture and apply processes.
For step 5, I have used the 'set_up_queue' in the 'dbms_strems_adm package'. This procedure creates a queue table and an associated queue.
The problem is that, in the propagation process, I get this error:
'ORA-25215: user_data type and queue type do not match'
I have checked it, and the queue table and its associated queue are created as shown:
sys.dbms_aqadm.create_queue_table (
queue_table => 'CAPTURE_SFQTAB'
, queue_payload_type => 'SYS.ANYDATA'
, sort_list => ''
, COMMENT => ''
, multiple_consumers => TRUE
, message_grouping => DBMS_AQADM.TRANSACTIONAL
, storage_clause => 'TABLESPACE STREAMSTS LOGGING'
, compatible => '8.1'
, primary_instance => '0'
, secondary_instance => '0');
sys.dbms_aqadm.create_queue(
queue_name => 'CAPTURE_SFQ'
, queue_table => 'CAPTURE_SFQTAB'
, queue_type => sys.dbms_aqadm.NORMAL_QUEUE
, max_retries => '5'
, retry_delay => '0'
, retention_time => '0'
, COMMENT => '');
The capture process is 'capturing changes' but it seems that these changes cannot be enqueued into the capture queue because the data type is not correct.
As far as I know, 'sys.anydata' payload type and 'normal_queue' type are the right parameters to get a successful configuration.
I would be really grateful for any idea!

Hi
You need to run a VERIFY to make sure that the queues are compatible. At least on my 10.2.0.3/4 I need to do it.
DECLARE
rc BINARY_INTEGER;
BEGIN
DBMS_AQADM.VERIFY_QUEUE_TYPES(
src_queue_name => 'np_out_onlinex',
dest_queue_name => 'np_out_onlinex',
rc => rc, , destination => 'scnp.pfa.dk',
transformation => 'TransformDim2JMS_001x');
DBMS_OUTPUT.PUT_LINE('Compatible: '||rc);
If you dont have transformations and/or a remote destination - then delete those params.
Check the table: SYS.AQ$_MESSAGE_TYPES there you can see what are verified or not

Mette

Difference Between Oracle Replication & Oracle Streams.

Hi All,
I am trying to evaluate Oracle Streams & Oracle Replication technologies.
I need to know what are exact differences between 2 technologies? Advantages (if any) of using Oracle Streams against Oracle Replication.
After reading Oracle Streams documentation, i found that it can capture DML as well as DDL changes, whereas Oracle Replication can capture DML changes.
Can someone provide more information?
Thanks in Advance.
Regards,
Vidyanand

Oracle Replication is designed to replicate exact copies of data sets to various databases. Oracle Streams is designed to propagate individual data changes to various databases. Thus, Replication is probably easier if the end goal is to maintain identical copies of data, where Streams is easier if the end goal is to allow different databases to react differently to data changes.
Oracle Replication is a significantly more mature product-- it is quite usable with older databases. Oracle Streams is a much newer technology and is only usable among different 9i databases. Most competent Oracle developers and DBA's are familiar with Oracle Replication, while many fewer have any real experience with Streams.
The Streams architecture strikes me as a lot more flexible than Oracle Replication's. This leads me to suspect that Oracle will be pushing Streams over Replication in subsequent releases, so I would expect new features in Streams, like DDL changes, that aren't in Oracle Replication. Realistically, though, I don't expect any serious movement away from Replication for at least a few releases, so I wouldn't tend to be overly concerned on this front.
