Question on replication in Oracle 10G Release 2

Good day,
I have a few questions on setting up replication that fits my scenario described below. Thank you in advance for reading and answering my post.
Scenario
I need to replicate 100-200 tables from the first OLTP server to the second DSS server that is read-only. The servers are physically located in different countries. Both servers use Oracle 10G Release 2. Required frequency of refreshes is 1-3 hours.
Questions
1. Is it optimal to use materialized views with fast/force refreshes for implementation of this scenario? If no, what are the better options?
2. How do network interruptions and latency affect stability of work of replication with materialized views?
3. How big is additional performance overhead at OLTP (source) server due to setting up replication with materialized views?

1) I guess it depends on how you define "optimal". It's certainly a reasonable option. You might also look at Streams or even logical standby databases. There are various trade-offs involved, so it really depends on your environment.
2) What does "stability of work of replication" mean, exactly? Obviously, if the network fails, the replication job(s) will generate errors. Depending on how you set things up, the replication process will be retried after increasing intervals until it succeeds.
3) Maintaining materialized view logs on the OLTP system could certainly impact performance-- the logs have to be maintained synchronously with the OLTP transactions. That may or may not noticably impact OLTP transaction performance-- it's probably roughly equivalent to putting a trigger on each of the 100-200 tables. Something like Streams is designed to put less load on the source system because changes are captured asynchronously.

Can we use replication usings oracle 10g steams for EBS r12 database?

HI,
We are using EBS 12.0.6 and database 10.2.0.3 on linux 32-bit/64-bit OS (Multi-Node env).
Actually We want to decrease the load of custom reports on actual production system, so thats why
we need reports server and as my past experience I had used oracle streams for replication with simple schema based replication and tablespace replication also.
So, please educate me, that can i used the oracle 10g streams for EBS schemas like APPS, GL ,INV, PO, ONT, ODM, AR, AP, CM etc?
Please provide us the above related env docs and road Map.
If you have any other way to create the Report Server?
Regard,
Fayaz Ahmed

Hi,
We are not in a position to upgrade the EBS from 12.0.6 to 12.1, because this is lengthy task, but we had already tested technically it in test env, but functional testing in pending.
Now we want to immediate solution if possible, because this is production?
So, please suggest another.
regards

Types of replications in oracle 10g

Hi
Iam new to oracle10g.
I want to replicate my database.
Before that i want to know how many types of replication methods are available in oracle 10g?
Thanks

There is no single correct answer to that question.
You've certainly got Streams and materialized views. You could subdivide each of those into three or four separate options based on the configuration (single-master vs multi-master materialized views, for example).
You might group technologies like DataGuard-- logical and physical and Change Data Capture (CDC) under the general banner of replication depending on how you define the term.
You could always write your own replication process using database links, triggers, etc. Or load and unload data via export & import, SQL*Loader, and/or external tables.
Transportable tablespaces might also fall under the replication rubric.
Depending on the problem you're trying to solve, the granularity you're counting, and what you consider "replication", you could come up with anything from 2 to 1002.

I'm not sure which of the linked articles you're following, but I expect that you're making things more complicated than they need to be. Those articles discuss configuring multi-master replication, but it sounds like you only need simple materialized view replication. In that case, all you'd need to do is
1) Create a database link from the destination system to the source system
2) Create a materialized view log on the source table on the source system
3) Create a materialized view on the destination that selects all the data from the remote table and is set to be fast refreshable and to refresh every 5 minutes.
On the destination system
CREATE DATABASE LINK to_source_system
CONNECT TO username_on_source_system
IDENTIFIED BY password_on_source_system
USING 'tns_name_for_source_system_on_dest_system';On the source system
CREATE MATERIALIZED VIEW LOG
ON table_to_replicate
WITH PRIMARY KEY
INCLUDING NEW VALUES;On the destination system
CREATE MATERIALIZED VIEW table_to_replicate
REFRESH FAST
START WITH sysdate + 5/(24*60)
NEXT sysdate + 5/(24*60)
AS
SELECT * FROM table_to_replicate@to_source_systemIf you have multiple tables that you want to be replicated in a transactionally consistent manner, you can put multiple materialized views into a refresh group and schedule a refresh of the refresh group.

2 way replication using Oracle 10g OID

Hi Friends,
Is it possible to have 2 way replication between Oracle E-Biz R12.1.3 and Microsoft Active Directory(windows 2008 server) at the same time using Oracle 10g OID.
Regards,
DB

Hi Leoncio,
Thanks and the requirement is :
1) user will be cretaed in Oracle e-biz R12.1.3 HRMS application and it should be replicated to Microsoft Active Directory (windows 2008 server)
2)E-mail address will be cretaed in Microsoft Active Directory (windows 2008 server) against an existing user and it shoule be replicated/updated in Oracle e-biz application User

Oracle 10g SEO replication to Oracle 10g EE RAC

Hi!!!
I have 200 nodes with Oracle 10g Standard Edition One and a DataCenter with 3 nodes Oracle 10g Enterprise Edition Real Application Clusters. My questions is, how to replicate data from each node to datacenter with the objective to centralize all data.
The database structure is the same in all nodes, and there is no conflict.
My real problem is Oracle Standard Edition One, it's not support advanced replication like Streams and Materialized Views, and i cant use other version of oracle because it´s huge money.
Please any advice?
Thanks in advance.

I'm more of an Oracle developer than a DBA, and I'm not sure this is feasible, but it sounds like you are in dire need of an idea, so here it is. Take the transaction logs from your 200 nodes, copy them to your central site (at whatever time interval you require), and peform a "restore" to the central server using those logs, even though they did not come from the central server.

REPLICATION BETWEEN ORACLE 10g and postgresql/MySQL/MSSQL SERVER??

Hi Friends.
I want to know if there are a manner of replication between ORACLE and (postgresql or mysql or mssqlserver).
Please, my email is [email protected]
Thanks
Manuel

Sure.
Are you talking about replicating data in one direction? If so, in which direction (Oracle to non-Oracle or non-Oracle to Oracle)? Or are you talking about bidirectional replication?
Which database do you want to be the "master" (i.e. initiate the push or pull of data)?
What sort of lag is acceptable? Minutes? Hours? Days?

Mv replication between Oracle 10g standared edition one and enterpriseedit

i have one ee 10g and 30 se-1 mv sites ,i have to replicate more than 100 tables from aabout 30 sites which have standared edition one to master site(enterprise edition0 .
1. Is it possible if yes then how?
2. is it will be 2 way updatable changes on both side will be replicate

Does each of the 30 sites have 100 tables (totally 3000 tables) ?
Are the tables "the same" -- meaning that you need to aggregate the rows from all 30 sites ? Or are they distinct ?
You cannot merge rows from multiple sources into 1 MV.
SE supports Read Only MVs. If you have 1-to-1 definitions you could try Updateable MVs.
MultiMaster Replication is certainly note supported with SE.
(Since you are running SE, I guess Streams and Golden Gate {too expensive} are not options).

Oracle 10g replication

hi,
i have two oracle 10g database installed in Linux machines. at present only one database server in live. now i want to configure replication between these two databases... so that i can use second server for any failure.
My requirement is..... i want to replicate entire database to second server and replication should run online.
actually i am new to this oracle..... so can any body help me to come out of this thing. and also give me step by step process to configure replication.
any immediate help will be highly appreciated.

Data replication and synchronization in Oracle 10g XE.

We are trying to do data replication and synchronization sort of thing for all our servers. We are using Oracle 10g. XE. I guess there are some features in oracle already for replication but I am not very sure about them.
To explain it more clearly - we will have individual database servers in our sub-divisions and then divisions and centers and then main server. We need to synchronize at various levels. So If any body is aware of any techniques, please let me know.

Hi,
Could you tell me what exactly synchronisation your talking about..?
we will have individual database servers in our sub-divisions and then divisions >>and centers and then main serverIf you have mulitple DB servers then you can connect it by DB links. also if you are talking DB synchronisation then you can have Triggers,Materialized views.
we also have two independent severs which are synchronised(atleast schema levels).

Replication of table from Oracle 10g to sql server 2000

Could i replicate table from Oracle 10g to sql server online. we have tables with same configuration and if any change happen in oracle 10g or sql server in that table we need to replicate that change to other database.
What is the solution for this two way replication between sql server and Oracle 10g

But the tutorial is saying that i will have to install Oracle database on the server already having sql server, is it client or whole database, if it is then it will acquire lot of resource.
I want to find out that for Heterogenous Service ODBC, we need third party software for ODBC Driver of SQL SERVER for Linux and secondly if we use Transparent Gateway then what are the steps for its configuration.
I could not find steps of configuration of Transoparent gateway, when i am trying to install Transparent gateway from Universal installer, it is not there. where do i find it , Do i need to purchase it too.

One way replication from MS sql server to Oracle 10g

Hi,
We are using Sql server 2005 windows 2003 32 bit and Oracle 10g 10.2.0.3 on linux 64 bit
Is it possible to replcate table data on real time from sql server (2005 32 bit or sql server 2000 32 bit)to oracle 10g running on linux 64 bit?
If yes then what are the steps.
It will be one way replication from sql server to oracle.
Which option is best sql server dts or Oracle Stream replication to replicate table data?
Regards,

If you want to push data from SqlServer, then ODBC, Linked tables, DTS etc.
If you want to pull data from Oracle, then Heterogenous Services / Gateway.

Replication of data from LDAP to Oracle 10g Database

Hi All,
in our application we are using Oracle Identity manager, and Oracle 10g database.
we are storing the user,profile and privilages in LDAP and due to some reason we have to create user table in the 10g database.
this user table values and LDAP user table values must be same.
here the source is LDAP and destination is Oracle.
so is there any way we can synchoronize or replicate the data from LDAP to 10g database?
since oracle identity manager is integrated with LDAP,
i feeel this must be possible.
but really dont know how?
kindly suggest me.
and if any examples available please let me know, i will be very greatful to you.
Thanks in advance

Deploying a J2EE web application in Oracle 10g

Hi friends,
 
I had worked with Oracle9i 9.0.3 . But it's my first experience with Oracle 10g . I have installed Oracle 10g Infrastructure , Metadata Repository and one Middle tier - Forms and i hope i have followed The Oracle 10g installation guide Properly. Anyway installation is successful.
The problem is a J2EE web application which is deployed properly on Oracle9i 9.0.3 doesn't get deployed in Oracle 10g. The following is the exception :
 
Deployment failed: Nested exception
Root Cause: deploy failed!: ; nested exception is:
oracle.oc4j.admin.internal.DeployerException: Error initializing ejb-module; Exception Error in application Spom_Apps: Error loading package at file:/C:/Oracle/Ora9iASForms/j2ee/home/applications/Spom_Apps/JmsSubscriberMdb.jar, Error deploying file:/C:/Oracle/Ora9iASForms/j2ee/home/applications/Spom_Apps/JmsSubscriberMdb.jar homes: No location set for Topic resource MessageDrivenBean JmsReceiverMdb
 
 
where JmsReceiverMdb is the deployment file containing the message driven beans.
 
Thanks in advance,

Hi,
Thanks for responding . I am sending the file contents of ejb-jar.xml, orion-ejb-jar.xml, jms.xml.
Could you also check whether dtds versions of 10g and 9i in these xmls are conflicting? If you can specify your email-id i can send these file as attachments.
Hope you could strike the right spot.
