Hi.
We are planing to use 10G stream replication for our production enviorment. But we are concenred over few things before we move ahead with option. Our prior experience with 9i stream replication was not that good.
9i does'nt functionality to do some advance maintenance task that could required on production enviorment. We are hoping 10G would be better option to go with streams.
However, following are few questions that we have regarding this product. Request your valuable inputs on Oracle 10G streams replication.
-->How effective this tool is compared to prior version 9i.
-->How stable Streams are with 10G? Are still there any know critical issues with stream replication 10G for e.g bugs or patches that are under review e.g?
-->For replication of production enviorment, would it be an ideal choice compared to third party vendor like golden Gate or shareplex.
You reponse would be greatly appreciated.
Thnks
RatheeshHi Rateesh,
-->How effective this tool is compared to prior version 9i.Very good. I use Streams in many production environments, even for bidirectional replication. Streams is very stable in 10g.
For replication of production enviorment, would it be an ideal choice compared to third party vendor like golden Gate or shareplex.It depends on several factors. It's better than GG and Shareplex by far (IMHO).
Madhu Tumma has some great Streams notes on this in his book "Oracle Streams":

Hope this helps. . . .

Oracle Streaming in 10g database
Hello,
I am trying do streaming at table level for all dml changes from one schema(source) to another schema (target) controlled by admin schema (stream_admin). I have all these schemas in same database(10g-enterprise edition).
As given in documentations , I created
1. two queues(in_Q and out_Q) in Stream_admin,
2. two process( capture and apply process) in Stream_admin ,
3. A propagation rule for propagation between in_Q and out_Q,
4. did instantiation,
5. started both capture and apply process.
Having done that , I insert in source table and check for the same in target but alas!! nothing happens. I fail to achieve streaming.
I am not getting any error. Neither in process , nor in propagation or queues. And all queues,rules and process are enabled.
Please help.go through below link

Please help.datapump uses dbms_metadata extensively.
Problem is twofold
- the amount of data
- why on earth do you need to 'copy' these 1.2 Tb a 'number of times'
One would expect you would have tested the upgrade on a smaller test database. and you wouldn't need to fix bugs in a 1.2 Tb database.
A better idea would be to duplicate the complete database using RMAN. This doesn't perform conventional INSERTs and doesn't create redo.

What are the permissions required for configuring Streams in 10g
Hi All,
Is admin privileges required for configuring Oracle Streams in 10g. Please confirm.
Thanks,
RedroWhat admin privilege are you referring to? There are many admin privs in the Oracle database.
What is absolutely required is reading the docs. Did you do so?
They are at http://tahiti.oracle.com
and they explain it all quite clearly.
There are also working demos here:

Is Oracle Streams included in Oracle Database 10g Express Edition?
Hi,
A short one - is Oracle Streams included in Oracle Database 10g Express Edition?
Thanks,
DagHi, I'm using Oracle Express in my Client System End. I want to know how we can replicate the data from server to client and server to client.
My Client DB : Oracle Express
My Server DB : Oracle 10G.
When the client is connected to the server I want to Syncronize all the Data from Client to Server and Server to Clinet.
Some of the Experts are telling to use Materilized View or Replication. Which one to use and How to use.?
It will be helpfull if I get a logic to do this Data Syncronization Process. -
Dear all,
i am trying to find a full example of setup oracle streams 10g. I found a lot of good examples on metalink but on oracle 9i not on 10g.
I highly appreciate your help.
WessamHi: Besides the initial setup, Streams has a lot of "gotchas." We have spent a lot of time researching performance issues with Streams, and how to avoid them. We provide a free pointpoint of the issues. We also documented some best practices. Here are the links:
http://oraclemagician.com/white_papers/streams_perf.pdf
http://oraclemagician.com/white_papers/streams.pps
Let me know if this proves to be helpful.

3 10g db's not connected by network, Oracle Streams?
Can I use Oracle Streams to replicate just using the swapping of hard drives? What is the best method to replicate like this? Roll your own?
RobYou can use Archive log downstream capture process in order to achive this.
You can copy archive logs to different site and configure capture, apply process on same database -
HTTP Pseudostreaming on oracle application server 10g
Hi,
I am fetching videos stored in database and show in website using JWPlayer.
The problem is in Apache Web Server I am able to move faward video but in Oracle App Server 10g
I found in documentation on JWPlayer regarding server need to enable HTTP Pseudostreaming
HTTP Pseudostreaming does not work by default on any webserver.
A serverside module is needed to enable it.
Here are the two most widely used (and open source) modules for this:
The H264 streaming module for Apache, Lighttpd, IIS and NginX. It supports MP4 videos.
The FLV streaming module for Lighttpd. It supports FLV videos.
http://www.longtailvideo.com/support/jw-player/jw-player-for-flash-v5/12534/video-delivery-http-pseudo-streaming#Servers
I need information regarding how enable video Pseudostreaming on oracle app server
-Thanks
Zohaib.No. Not only it isn't certified, but it is also impossible to run forms compiled with the 11g compiler with the 10g runtime. For 11g there is a install bundle for the developer suite / application server.

Performance tuning and Periodic Maintance in Oracle Streaming Environment
We had Setup the Bi-Directional Oracle Streaming between two remote Sites each of 2-Node RAC Databases
This is Our Enviroment Summary.
Database Oracle 10g R2 version 10.2.0.4.0
Os: Solaris[tm] OE (64-bit)
Currenly Oracle Streaming working Successfully and I'm Daily Monitor the Same.
As Mention in the Master Note for Streams Performance Recommendations [ID 335516.1]
Purging Streams Checkpoints
10.2: Alter the capture parameter CHECKPOINT_RETENTION_TIME from the default retention of 60 days to a realistic value for your database.
A typical setting might be to retain 7 days worth of checkpoint metadata :
exec dbms_capture_adm.alter_capture(capture_name=>'your_capture', checkpoint_retention_time=> 7);
My Query
===> Currenly In My Environment CHECKPOINT_RETENTION_TIME is as default 60 days
I want to change the checkpoint_retention_time=> 7 so what should I take care for before execute the above command in my Live Streaming Environment.

Data Guard with Oracle 9i and 10g -- have you done it?
We have an ERP system (JDEdwards, db size approx 600 GB) and we'd like to copy the data in this system to a database on another computer. We'd use the remote database for reporting, so we need it to be available. We are looking at using Data Guard running in Logical Standby mode.
The ERP database is Oracle 9i, and we are considering having the Logical Standby database be 10g. Have you done this and if so, what was your experience?
Here's why we want to do this. There are many tables in the ERP database that contain descending indexes. We can't change this, and it is not supported with Data Guard under Oracle 9.2. Tables with descending indexes do not copy to the logical standby database.
We were told that this is corrected in a newer release of Oracle, and we were wondering if a 10g database would properly copy tables with descending indexes.
Thanks in advance for any experiences you can share.
Best Regards,
MikeWhat you are trying to do might not be possible. Because when you create logical standby you have to create a physical standby first and convert it. Primary and standby have to be same version.
In furture it might be possible because 10G will support rolling upgrade of logical standby.
However even it's possible you have to go through a lot of pain to setup and maintain it because Oracle don't support the setup.
What you could try are Stream and Replication, I will say Stream is very interesting one. Because Oracle say : "Oracle Streams and Oracle Data Guard (including Data Guard SQL Apply) are independent features based on some common underlying infrastructure and technology. "

Capturing data of the previous time interval with Oracle Stream(HotLog)
I read from 10g Oracle manual that Oracle Steam can capture data within specified time interval with begin_data and end_data options.
For example :
BEGIN
DBMS_CDC_PUBLISH.CREATE_CHANGE_SET(
change_set_name => 'set_cns',
description => 'set_cns...',
change_source_name => 'HOTLOG_SOURCE',
stop_on_ddl => 'y',
begin_date => sysdate,
end_date => sysdate + 1);
END;
However if I set begin_date to previous time from now, Oracle doesn't caputre data anymore in this case.(HotLog method)
(I set begin_date => sysdate - 1/24
end_date => sysdate + 1/24.)
Does anybody know to capture the previous time interval with Oracle Stream?Change C2 to:
cursor c2(passing_date IN date) IS
SELECT MONITOR_ID, SAMPLE_ID,
COLL_TIME, DEW_POINT
FROM ARCHIVE_DATA
WHERE COLL_TIME < passing_date
ORDER BY COLL_TIME desc;And rather than populating a table with the three records, you could just select the three records using: where COLL_TIME between Prev3_time and Prev1_time -
Difference between Oracle 11i Apps DBA & Oracle Application server 10g DBA
Hi All....
can anyone explain me the *"Difference between Oracle 11i Apps DBA & Oracle Application server 10g DBA"*
Can Oracle 11i Apps DBA work in a Oracle Application server 10g DBA environment.
Regards,Oracle Apps is a suite of financial applications.
Oracle Application server is Oracle's scaled up implementation of Apache or Weblogic or similar products.
While Oracle Apps might use Oracle Application Server as middleware, Oracle Apps is much, much more than Oracle Application Server.
An Oracle Apps DBA is primarily busy on the functional side, and with implementing an ongoing stream of patches ;)
The two functions have almost nothing in common.
