Table replication using streams uni-directional

Hi,
I recently started using streams and configured the table level replication using streams. I have configured all required processes in a "local capture" method and capture, propogate processes are running fine (status shows to be fine). The apply process at target database is running fine. The logminer is minging the redo logs as per the alert log at source. But i do not see any changes applied on target. suppose, i insert a row at source table it should be appeared at target after some time.
I am trying to find if there is any thing not satisfied at the apply level. I am looking for some directions on the below questions. please dont point me to some links please as i have been going through several sites.
What is captured on source is formed into a LCR. Now, how can i see an LCR at source database (through a query or procedure) when any insert or update is done at source?
How can i see if the LCRs are propagated to target database or not?
If LCRs are propogated properly what query or any object helps me to find out what is in the LCR at target site?
You may probably ask me any questions related to streams configuration and i will check if i have done it properly or not.
Regards,
sree

Hi,
Thanks for your reply. Yes. It is 11g.
In my later research i found the below error message from the alert.log at apply site.
knllgobjinfo: MISSING Streams multi-version data dictionary!!!
knlldmm: gdbnm=STRM2.ORDB.NET
knlldmm: objn=16914
knlldmm: objv=1
knlldmm: scn=17541786
When checked on the source site, the SCN i retrieved is,
At Capture Site:
==========
SQL> SELECT DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER FROM DUAL;
GET_SYSTEM_CHANGE_NUMBER
17550440
At Apply site:
=========
SQL> SELECT DBMS_FLASHBACK.GET_SYSTEM_CHANGE_NUMBER FROM DUAL;
GET_SYSTEM_CHANGE_NUMBER
17550779
When looked at the metalink note, i found that it might be an instantiation issue or the Issue with Propogation. I am trying to get help from the oracle documents but it looks like it might take little more time. Can you quickly guide me.
How to make sure that propogation is going fine. It is understood that there occurs when the Streams data dictionary information for the specified object is not available in the apply database.
I have instantiated my table at source using DBMS_STREAMS_ADM.ADD_TABLE_RULES and added propagation rules DBMS_STREAMS_ADM.ADD_TABLE_PROPAGATION_RULES as well. Later i stopped capture and apply, executed DBMS_CAPTURE_ADM.PREPARE_TABLE_INSTANTIATION at source (nothing done at destination), restarted the apply, capture process. I believed that it would do the instantiation again.
How to make sure that the instantiation is done properly?
Thank you for your patience.
Regards
Sree

Replicate to a different schema using streams

All,
I'm performing replication using streams, I have read the doc and steps by steps notes on metalink getting the replication successfully.
But now, I want to do the same but on differents schemas ie.
source DB: Schema= A Table=test
Destination DB: Schema= B Table=test
On both databases the schemas are basically the same but with different names.
What changes o additional steps I need to perform in order to complete the replication?
Thanks in advance..!

Here is the procedure
1) Follow the instructions from the documentation to create the streams administrator user on both source and target.(e.g. steams_adm)
2) Connect to the streams administrator user at the TARGET (10.2) database
--Create a queue
Begin
Dbms_streams_adm.set_up_queue(
queue_name => 'APPLY_Q',queue_table => 'APPLY_Q_QT');
End;
--Create rules for apply process

end;
begin
dbms_rule_adm.create_rule_set(rule_set_name => 'streams_adm.apply_ruleset',
evaluation_context => 'SYS.STREAMS$_EVALUATION_CONTEXT');
dbms_rule_adm.add_rule(rule_set_name => 'APPLY_RULESET',rule_name =>'APPLY_RULE');
end;
--Set the rule to rename the schema
begin
dbms_streams_adm.rename_schema(
rule_name=>'APPLY_RULE',

end;
BEGIN
DBMS_APPLY_ADM.SET_PARAMETER(
apply_name => 'APPLY_CHANGES',
parameter => 'DISABLE_ON_ERROR',
value => 'N' );
END;
--Start apply
begin
dbms_apply_adm.start_apply('APPLY_CHANGES');
end;
3) Connected as strmadmin on SOURCE (9.2) database:
--Create a database link to the TARGET database connected as streams_adm. The name of the dblink must match the target database name since you have to set global_names=true in the init files of both databases

begin
dbms_rule_adm.create_rule(rule_name =>'FILTER_TABLES',
condition => ':dml.get_object_owner()=''<put your schema owner>'' and :dml.get_object_name() in (''TAB1'',''TAB2'')');
end;
begin

destination_queue => 'streams_adm.apply_q',
destination_dblink => '<database link>',
rule_set_name => 'streams_adm.capture_ruleset');
END;

There are demos of both Change Data Capture (superior for what you appear to be doing) and Streams in Morgan's Library at www.psoug.org. Some of them duplicate exactly what you describe.
PS: There is a specific Streams forum. In the future please post Streams related requests there. Thank you.

Partial replication of tables using streams

I need to replicate a subset of master table (few columns) to another database. destination tables are read only. But this needs to happen in real time. I was using oracle streams to replicate entire table. To make it partial, can we have something like streams replicating materialized views from maser. Any clue on how can this be achived with better performance.

The data needs to be replicated in a few seconds, if we run a materialized view on all the tables in seconds, will it not have a performace impact on the source database.Since some tables needs to be replicated entirely at real time we are using streams for those tables.Now to get a partial one, I am trying to create a rule set with delete_columns, rename_columns etc combination of dbms_rules package.
Any links that could help this construction?
Do you still feel that materialized viwe would be a better alternative to the problem, to replicate few columns of lot of tables in real time?

Can we capture changes made to the objects other than tables using streams

Hello All,
I have setup a schema level streams replication using local capture process. I can capture all the DML changes on tables but have some issues capturing DDL. Even though streams are used for sharing data at different or within a database I was wondering if we can replicate the changes made to the objects like views, procedures, functions and triggers at the source database. I am not able to replicate the changes made to the views in my setup.
Also, when I do a "select source_database,source_object_type,instantiation_scn from dba_apply_instantiated_objects" under the column 'object_type' I just see the TABLE in all the rows selected.
Thanks,
Sunny boy

Hello
This could be a problem with your rules configured with capture,propagation or apply. Or might be a problem with your instantiation.
You can replicate Functions, Views, Procedure, Triggers etc using Streams Schema level replication or by configuring the rules.
Please note that the objects like Functions, Views, Procedure, Triggers etc will not appear in the DBA_APPLY_INSTANTIATED_OBJECTS view. The reason is because you do a schema level instantiation only the INSTANTIATION_SCN in DBA_APPLY_INSTANTIATED_SCHEMAS is accounted for these objects. At the same time tables would get recursively instantiated and you would see an entry in DBA_APPLY_INSTANTIATED_OBJECTS.
It works fine for me. Please see the below from my database (database is 10.2.0.3):
on capture site_
SQL> connect strmadmin/strmadmin
Connected.
SQL> select capture_name,rule_set_name,status from dba_capture;

These Functions, Views, Procedure, Trigger are created on the source and got replicated automatically to the target site TARGET.WORLD. And note that none of these objects are appearing in DBA_APPLY_INSTANTIATED_OBJECTS view.
I have used the above given rules for capture. For propagation I dont have a ruleset itself and for apply I have same rules as of the capture rules.
Please verify your environment and let me know if you need further help.

let me tell you something, in GCF everything you fetch through GPRS is bound to come as an inputstream and whatever request you send is passed as outputstream. so if you have worked with GCF, you have worked with streaming already. isn't it.

Can I stream things directly from the time capsule to my AppleTv without using my computer?

I have an older MacBook and I'm worried about the storage so I want to get things moved to a Time Capsule. I was just wondering if I can stream things directly from the Time Capsule to the AppleTV without having to store them in iTunes on my computer and play them off of there.

You cannot stream from a TC .. it is not a media device.. you can store movie files on the TC but you still need to run the computer to play them.
Depending on how you connect this can cause dramatic slowdowns.
A WD Live TV can play raw movie files from a TC.. because it is not a media streamer which is all the ATV is, it is a full media player.

How can I used Streams?

I have one source database(RAC).
and four destination database.
Now , I used materialed view for replicate tables.
I'll change to oracle steams.
How can I do?
please introduce me

Surachart,
A basic setup would consist of a capture process and four propagation processes on the source database, and four apply processes at the targets.
Uni-directional streams and less moving parts and is thus easier to manage than bi-directional.
You shouild experiment by replicating a dummy table containing a few columns until you are clear about the roles of the various processes and the commands to manipulate them.
Check out the "WeDoStreams" blog for some easy to follow tutorials on streams steup, of various levels of complexity.

How do we use "streams" functionality in Oracle 8i?

Hello Gurus,
Oracle Streams is only available as of Oracle 9i. I need to replicate data from an Oracle 8i database to another database. The tables don't match exactly and i want a solution that can mimic streams. How can that be done? Is there any sample code available to do this type of streaming between Oracle 8i dbs?
Thanks.

You can use Materialized views (used to be called Snapshot) or Advanced Replication. But I think AR is an extra option not included in Enterprise Edition.
You could also develop trigger based replication using database link. But I advice you don't go that way. Don't reinvent the wheel. Think of what happens when one db goes down - you don't want the other to sink with it...
You should give Snapshot a try. Look for fast snapshot refresh. It uses incremental log, so it is a lot faster in most cases.
You need at least 9i R2 to use Streams, but you're better off with 10.2.0.3.

Problem in Update using STREAMS in Ora 10g EE

Hi
I am using Oracle 10g Enterprise Edition for replicating datas after failover occurs in DB
I had followed the steps in below URL..
http://blogs.ittoolbox.com/oracle/guide/archives/oracle-streams-configuration-change-data-capture-13501
The replication is achived using streams.
INSERT,DELETE operations working fine without any issue. But UPDATE operation is not replicated immediately.
I did UPDATE and gave COMMIT, no replication. Again I did UPDATE and gave COMMIT, now only it updates the Streams table.
For every UPDATES it needs two times? Why? How to solve this?
Or Any other URL which gives working examples of Streams in 10g..
Any help regard this highly appreciated..

Thanks for ur reply..
There is no specific reason to use STREAMS..
I have to replicate the data during my properity database stated up.
We already discuss with this topic
Data Replication in after downtime
Instead of using Triggers or procedure, i have to use anyone of the technologies in Oracle 10g for DataReplication..
Can you give me more info like advantages of using DataGuard or other techologies in Oracle 10g EE .

Oracle Replication and SQL*Load direct Path

We are setting up Oracle replication and have a few tables which are loaded using SQL*Loader Direct path. I have following questions:
1. Can MultiMaster replication replicate direct patch sqlloaded data.
2. If the answer to the above question is no, should we set up a new snapshot replication group . All other tables are in the Multi Master replication.
3. Another question is on the number of replication groups. How many of these we should create. We have total of about 500 tables and database size is about 450 Gig. We plan to replicate all the tables and the refresh interval we want to be one minute for all the tables. Does having more/less replication groups help??
Thanks for your help

We are setting up Oracle replication and have a few tables which are loaded using SQL*Loader Direct path. I have following questions:
1. Can MultiMaster replication replicate direct patch sqlloaded data.Yes, I don't think it should matter how the table is getting updated.
2. If the answer to the above question is no, should we set up a new snapshot replication group . All other tables are in the Multi Master replication.see above
3. Another question is on the number of replication groups. How many of these we should create. We have total of about 500 tables and database size is about 450 Gig. We plan to replicate all the tables and the refresh interval we want to be one minute for all the tables. Does having more/less replication groups help??
Thanks for your help I believe what Oracle recommends is that you split up your tables into replication groups transactionally. I personally have 6 replication groups supporting 700+ tables. They are broken up more by business function than by number and size.

Creation of External table by using XML files.

I am in the process of loading of XML file data into the database table. I want to use the External Table feature for this loading. Though we have the external table feature with Plain/text file, is there any process of XML file data loading into the Database table by using External table?
I am using Oracle 9i.
Appreciate your responses.
Regards

Hi,
The XML file which U posted is working fine and that proved that external table can be created by using xml files.
Now My problem is that I have xml files which is not as the book.xml, my xml file is having some diff format. below is the extracts of the file ...

My problem is the Item Name and Direction the value of both(ex PSCReceived or UASReceived) will be treated as the coulmn name of the table and '0' would be the value of that column. I am confused how to create the external table creation program for that.
I would really appreciate your responses.

Data are not transfered to a table view using signal out

Hi all,
we have recently upgraded to SP16 and I'm now facing a problem on my model that worked fine when we were on SP15.
I have a data service returning data to my model. The data are transfered to a signal out element and then displayed into a table view using a signal in element. Now the table view remains empty.
I have checked that the dataservice returns data because if I directly connect my table view with the dataservice the data are displayed. But my requirement is to use signal in/out elements.
This error was not appearing in SP15.
Any ideas?
Regards
Panos

After doing some tests I found out that if you have a model that has more than 2 signals in/out then the 3rd one will not work. This is definitely a bug.
Hope that soon there will be a SP without any new bugs!
