Replication between 130 nodes and 1 Data Center

Hi everyone.
I have 130 database nodes (Oracle Standard Edition One) with a big distance of separation, and 1 Data Center with 3 nodes (Oracle Real Application Cluster 10g R2). The connection between nodes and datacenter is through various ISP ( WAN).
I have exactly the same model design of database in nodes and datacenter.
DataCenter is a repository of data for reporting to directors and dictate the business rules to guide all nodes.
Each node have approximately 15 machines connected with desktop application.
In other words Desktop Application with a Backend Database (node).
My idea of replication is not instantly, when a transaction commit in a node then replicate to datacenter. Also over nigth replicate images because is heavy, approximately 1 mg per image. Each image correspond to one transaction.
On the orher hand i have to replicate some data from datacenter to nodes, business rule, for example: new company names, new persons, new prohibitions, etc.
My problem is to determine th best way to replicate data through nodes to datacenter.
Please somebody could suggest me the best solution.
Thanks in advanced.

Last I checked, Streams and multi-master replication require enterprise edition databases at both ends, which rules them out for the sort of deployment you're envisioning.
If a given table will only ever be modified on nodes or on the master site, never both, you can build everything as read-only materialized views. This would probably require, though, that the server at the data center have 130 copies of each table, 1 per node. For schemas of any size, this obviously gets complicated very quickly. For asynchronous replcation to work, you'd need to schedule periodic refreshes, which assumes that you have relatively stable internet connections between the nodes and the data center.
I guess I would tend to question the utility of having so many nodes. Is it really necessary to have so many? Or could you just beef up the master and have everyone connect directly?

  • Replication between Oracle Server and MS SQL Server

    Hello,
    Does anybody know of a well known or reliable software that can do data replication between Oracle Server and Microsoft SQL server.
    I suppose I can write my own version using Heterogenous Services in Oracle but I would like to know if such an automated replication between Oracle and SQL is available commercially.
    Thank you.

    Sorry, Aman,
    I couldn't find any info about replication to MS SQL. Is it possible at all? Could you provide link where we can read about this? It could be very interesting.Sorry Viacheslav, even I couldn't find anything for the same. I am not sure that it can be done or not, I haven't heard anyone in my contact doing so. The only place where I have seen Streams being used around me is within Oracle db only. May be someone else can help if he/she has done it.

  • Difference between Interface node and normal node?

    What is the main difference between  Interface node and normal node?
    Cheers
    Aisurya.

    Hi surya,
    Interface node or methods comes into picture whenever you want to use one component as used component. I mean to say
    Component usages. If you select node as interface node, it will available in another component so you can use that node or methods.
    Normal node means in that component only. Simply we can say for component usages we go for interface nodes.

  • Difference between Business area and profit center accounting

    Hi Frnds,
    Can any body explain about difference between business area and profit center accounting .

    Hi
    Business area will have many profit centers. For example Vehicle is a business area in a company. Vehicle can be cars and Bikes etc. Here Vehicle is business area and Cars and Bike are profit centers. In broad Vehicle is a profit center. But as it has sub areas those are profit centers. So profit centers cannot be replaced with business area and vice versa. We can replace business area by Profit centre, only condition is that it should be in same controlling area. The business area is more like a business unit of a company. You can have multiple profit centers within a business area.
    Main distinguish factor is that distribution and assessment in possible in profit center but not in business area.
    One more distinction is that Business area need not be attached to any organisation structure. But profit centres can be created only under the controlling area. Business area can be across controlling area.
    Business area concept is used for making stragic decisions by the management whereas the primary purpose of profit centre accounting is responsibility accounting.

    With Data Guard Broker:

    See especially why you want to use the broker:
    http://download.oracle.com/docs/cd/E11882_01/server.112/e17023/concepts.htm#i1013106
    In short: You should have a good reason if you do not use the broker, because it is the officially recommended way to maintain Data Guard. It is even required for some features like Fast-Start Failover.

  • Difference between relational integrity and data intigrity

    hi
    could anybody tell me
    what is the difference between
    relational integrity and data intigrity
    tahnx
    kals.

    hi,
    Data Integrity
    Data integrity means, in part, that you can correctly and consistently navigate and manipulate the tables in the database. There are two basic rules to ensure data integrity; entity integrity and referential integrity.
    The entity integrity rule states that the value of the primary key can never be a null value (a null value is one that has no value and is not the same as a blank). Because a primary key is used to identify a unique row in a relational table, its value must always be specified and should never be unknown. The integrity rule requires that insert, update, and delete operations maintain the uniqueness and existence of all primary keys.
    The referential integrity rule states that if a relational table has a foreign key, then every value of the foreign key must either be null or match the values in the relational table in which that foreign key is a primary key.
    What is a Relational Integrity?
    A relational database contains tables of data which are related to each other. For example, articles are related to the author who wrote them, and conversely, authors are related to the articles they wrote. (Sounds obvious, and it is.) That's the relational part.
    When we work with a relational database, we naturally expect that data in related tables stay related. For example, articles written by MartinB should always be related to MartinB and never be confused with articles written by any other author. That's the integrity part.
    Relational Integrity is also called Referential Integrity, perhaps because the mechanism for ensuring integrity is implemented by the way the tables reference each other. Both terms are okay with me. I usually just say RI anyway.

  • Difference between hierarchy node and single value

    Hi experts,
    Can anyone explain me the difference between hierarchy node and single value?
    This is my problem:
    I have a query that uses a characteristic (0ORGUNIT) with a hierarchy and I execute it without any problem but when I try to set a fliter on this characteristic and I try to find a single value, for example 101, it doesn't appear in the single value list, instead it appears in the hierarchy nodes list in the selection window.
    I think I'm confused about both terms because I thought  a hierarchy node was always the one who has one or more values as its lower levels like this:
    A. 10
        A1.  100
        A2.  101
        A3.  102
             A3.1.  1021
    B. 11
    I this case I thought , for example, 101 was a single value but not a hierarchy node so I must find it in the single values list in the selection window, however, 102 can be both and must appear in both lists, is it true?
    Thanks in advanced

    In BW, hierarchy node with more information compare to the single value. for example, it always carries its father node information, which it belongs to. and some time information if it is time-dependent.
    So, when you using hierarchy node, it means at least 2 information: value and "position" (who is its father node)
    That's the reason why you see the hierarchy tree when choosing the node.
    If you want to expand the hierarchy to the certain level, you can setting in the property. Another choice is restrict in the query designer.

  • Data Replication between Oracle 9i and 10g

    Hello,
    I have a question regarding possible Replication Models between Oracle 9i and 10g. Does anybody know a possible way to syncronize the schema data between a 9i and 10g database in realtime?
    If yes can you please post perhaps a link with a kind of how to?
    Many thanks to all,
    Bob...

    You can read this metalink note 370850.1 - there are bit more ways of replication discussed.
    Yes, platforms can be different, but recomendation is to use the same platform for both databases.

  • Replication between 2 node RAC environment and standalone

    I would like to find out if we can setup replication between a (2 node) RAC environment and standalone database located at different location. Any help regarding this would be greatly appreciated.

    Thanks for the reply.
    Consider for a moment I cannot implement dataguard/stream -- because I believe both involves licensing issue --- now only option left is writing my own code. If I right my own code what are the prerequisites for this and what do I have to keep in (technically)mind before i start implementing this. Any help or any lead would be greatly appreciated.

  • Replication between Oracle 7 and Oracle 10g. Is it possible?

    Hello,
    I have two DBs which exist on two different versions of Oracle (7.3.3 and 10g). Those DBs have different structures of tables, data from which can be casted from one structure to other. Can I organise bi-directional replication between those DBs. To make the point clear, can I replicate data from Oracle 7.3.3 to 10g and vice versa.
    Duration of synchronization should be less than 1 minute.
    I would be very pleased if somebody gives my a reference on online oracle documentation because I can't find answer in it to my questions.
    If the possability of application of replication is questionable, can you give an advice which technology I have to apply in my situation. For instance, perhaps, it is convenient to use triggers.
    Thank you.

    Hi,
    ObjectMMRS (http://www.object.com.br/wiki) can make what you need, replicate data between different Oracle database versions and between Oracle and other database brands too.
    Documentation still in Portuguese only (Translation in progress) but I can help you install and try, maybe one or two days of work and you will be able to replicate.
    Contact me at [email protected] if you want to try the ObjectMMRS (low cost replication software suite), no technical support fees for trial, and 30 days license expiration.

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

    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?
