Of many level replication table

Hi all

I was configuration of replication of flow between a table at many tables (3) in the same database (10.2.0.4)
Below figure states my requirement.

                                    |--------->TEST2.TAB2(Destination)  
                                    |
TEST1.TAB1(Source) ---------------->|--------->TEST3.TAB3(Destination)
                                    |
                                    |--------->TEST4.TAB4(Destination)
Here are the steps I followed. But replication does not work.
CREATE USER strmadmin 
IDENTIFIED BY strmadmin
/ 

GRANT CONNECT, RESOURCE, AQ_ADMINISTRATOR_ROLE, DBA to strmadmin; 

BEGIN 
DBMS_STREAMS_AUTH.GRANT_ADMIN_PRIVILEGE( 
grantee => 'strmadmin', 
grant_privileges => true); 
END; 
/ 

check  that the streams admin is created: 
SELECT * FROM dba_streams_administrator; 


SELECT supplemental_log_data_min,
supplemental_log_data_pk,
supplemental_log_data_ui,

  • Rename two-way level replication Tables/columns / schema

    I have a bidirectional 10.2 - level schema replicated configured environment. Enforcement staff feels the need to rename tables or columns. We are DDL replication.

    It is: after we modify rename table, it is necessary/best practices/best practice to run DBMS_CAPTURE_ADM. PREPARE_SCHEMA_INSTANTIATION? We we cast no re-instantiation. In our lab tests, I did not saw that it had to be done, but curious if it must be done.

    Mike,

    You don't need to run DBMS_CAPTURE_ADM. PREPARE_SCHEMA_INSTANTIATION again after the table has been renamed or some DOF has been issued on this subject. If you rename a table, the object_id does not change. This object that spread in the target with the same object_id already has information flow existing dictionary on the site to apply it and so you do not need to rerun PREPARE_SCHEMA_INSTANTIATION on the source.

    SQL > set off head
    SQL > create table xx22 (x number);

    Table created.

    SQL > select object_id from user_objects where object_name = 'XX22;

    84717

    SQL > alter table rename xx22 XX33.

    Modified table.

    SQL > select object_id from user_objects where object_name = 'XX33. "

    84717

    If you add additional columns and you feel these columns must be connected supplementally then you can manually enable additional logging for these columns.

    Let me know if you have any other doubts.

    Thank you

  • Merits and demerits of the replication of schema-level and Table

    Hello

    We evaluate the streams for our needs of replication. We reproduce nearly 2000 two-way tables. Most of the tables are in a schema. The main schema has a few tables that are not replicated.

    Replicate us schema level? Or at the level of the table? What are the advantages and disadvantages?

    Replication of level schema included with a handful of exclusionary rules seems simpler.

    In water courses at the level of the tables as well as creating 2000 table rules in the beginning, add a new table to an existing configuration of streams, will require additional steps to stop capture/apply/spread, creating new rules for the new table and restart replication. However, it seems that level replication table offering flexibility in terms of group tables. We wanted to group tables about 10 groups of 20 to 300 tables in each group. Each group will have its own capture, propagate and apply. In this way, we can isolate large groups of those unimportant?

    Who is a better setup in terms of maneuverability, flexibility, parallelism and performance?

    Thank you.

    Hello Stargaze,

    OK, so I understand that the grouping is based on the type of transactions and its importance. In this case the grouping would help you in many ways such as:

    1. If you encounter a problem or a bug with one of the processes of capture/apply then the other groups would work fine. Therefore, you have the opportunity to shoot a game of capture, propagation and applies until solve you the problem.

    2. in case if you perform any load batch where the transaction will affect over 10000 + records then it is possible that you could get stuck at 'SUSPENDED for FLOW CONTROL' on any of the feed items. With different groups would give you more flexibility to solve this problem by activating and deactivating groups.

    For more information on this please check the following:

    Apply process is active, inactive, and just stopped in change application

    3. with the schema level replication even if you have the advantage of being simple and have fewer rules in the set of rules, you must consider the 2 points above before you implement it. You need to test both diagrams and tables with a typical load (simulation of the production) and need to identify potential problems in both. Some more points to consider:

    -apply the game patches 10.2.0.4 or at least 10.2.0.3
    -apply all the patches required streams (Note: 437838.1> on metalink)
    -follow the recommendations as indicated:
         Note: 418755.1 broadcast 10.2.0.x.x of recommendations
         Note: 335516.1 Performance of flow recommendations

  • Skip a level of table

    Hi, I have these 3 tables (right FKs and joins) in my Dimension product:

    CITY, SUPPLIER, PRODUCT.

    The right hierarchy should be high in leaves: City-> provider-> product

    We would like to build the hierarchy of these dimensions:

    City-> product, but we get this warning in BI Admin (and the error then in the answers)

    [39008] logical dimension CITY table has a source of the CITY who do not adhere to any source of fact.

    It cannot sail in joins, the level of the intermediate jump table?
    Are we obliged to build the whole hierarchy and spend level (and table) defining a privileged way of exploration? (this solution worked)

    Thanks in advance!

    To resolve this problem, you have two options.

    Don't forget that you have in the correct join FK relationships of physical layer between these tables as follows:

    City-<><>

    In the MDB do logical table (dimension table) with source logical table product. Now, in the source of the product logic table properties general tab add physical tables and joins (add first table beg and join product >-provider, and then add the picture of the city and join provider >-City). Now, drag - move the columns in all tables that you want to use in the levels in the dimension.

    Build the dimension with levels object and columns on each level.

    Option 1 (all three levels):

    The city level: use for drilldown checked key
    Provider level: use for the uncontrolled descent of key
    Product level: use for extraction of key checked or unchecked

    Now you can dig in the answers given by the city to the product, the intermediate level is not displayed, obiee do reach across the three tables.

    Option 2 (city and produced only in levels):

    The city level: use for drilldown checked key
    Product level: use for extraction of key checked or unchecked

    Now you can dig into the responses made by the city to the product, obiee do reach across the three tables, because you set this additional physical tables and joins in logical table product source.

  • Synchronization in active two-way replication tables

    Hello

    I have a table on two sites A and B with the same name and structure but with different records. How can I synchronize two tables before you activate the active replication.

    Thanks and greetings

    Mohamed Ahmed

    Hi Rudy,.

    Yes, you can... Manually, you need to insert the missing records at both sites (wherever necessary). Because to enable replication goldengate, records must be the same on both sides (two sites).

    I think that, if you go ahead with replication without organizing, then you will end up by with duplicate records. Sometimes the process may ABEND. It comes to creates data integrity problems.

    If the table has the primary key?

    Kind regards

  • No fact to required level error table.

    I have a single dimension

    Account

    Two fact tables

    Threshold and Transaction

    These tables are attached to the Sun of account using the account number.

    Now when I create an analysis using account numbers of all three paintings, it says no table of facts to the required level. If I understand any other fact from the two fact tables, it fills the null value. He works at the time when I create a scan from a single dimension and fact tables.


    Why do we get this error and how it should be modelled.

    Published by: 979130 on December 29, 2012 12:52 AM

    I'm not sure of your data... I give a few try options than them any one should work.

    Assuming that the two facts are able to granular: you create the logical fact table in MDB add first fact as source then, Assistant to open the properties, and another fact table.

    Assuming that the two facts are to different or even granular: you create the logical fact table in MDB add first and then add 2nd fact as the 2nd source of logical table and set the tab content for these two facts

    Using the option you go for metrics and use them in the report.

    In general: you must let the BI server do know how the data is distributed on tables so that BI server can answer that you expect.

    Hope this helps, Appreciate if you mark as correct/good

    Impact of surgery Maintenance of Partition on a Table partitioned local index
    Whenever a partition maintenance operation takes place, Oracle locks the partitions of the table concerned for any DML operation. Data in the affected partitions, except a FALL or a TRUNCATION operation, are always fully available for any operation selection. Given that clues them are logically coupled with the (data) table partitions, only the local index partitions affected table partitions must be kept as part of a partition maintenance operation, which allows the optimal treatment for the index maintenance.

    For example, when you move an old score a level of high-end storage at a level of low-cost storage, data and index are always available for SELECT operations. the maintenance of the necessary index is either update the existing index partition to reflect the new physical location of the data or, more commonly, relocation and reconstruction of the index to a level of storage partition low cost as well. If you delete an older partition once you have collected it, then its local index partitions deleted, allowing a fraction of second partition maintenance operation that affects only the data dictionary.

    Impact of surgery Maintenance of Partition on Global Indexes

    Whenever a global index is defined on a table partitioned or not partitioned, there is no correlation between a separate partition of table and index. Therefore, any partition maintenance operation affects all global indices or index partitions. As for the tables containing indexes, the affected partitions are locked to prevent the DML operations against the scores of the affected table. However, unlike the index for the local index maintenance, no matter what overall index remains fully available for DML operations and does not affect the launch of the OLTP system. On the conceptual and technical level, the index maintenance for the overall index for a partition maintenance operation is comparable to the index maintenance which would become necessary for a semantically identical DML operation.

    For example, it is semantically equivalent to the removal of documents from the old partition using the SQL DELETE statement to drop old partition. In both cases, all the deleted data set index entries must be removed to any global index as a maintenance operation of normal index that does not affect the availability of an index to SELECT and DML operations. In this scenario, a drop operation represents the optimal approach: data is deleted without the expense of a conventional DELETE operation and the indices are maintained in a non-intrusive way.

  • How to find level locks table

    Oracle APPS R12

    Hi all

    How to determine the table level locks in oracle Apps R12. When I run my simultaneous program its taking too much time to complete, and two or three concurrent programs are running in parallel and taking the same base table data, so how to find the locks if it is on the table. Any help is highly appricatable.


    Thanks and greetings

    When I run my simultaneous program its taking too much time to complete, and two or three concurrent programs are running in parallel and to the same base table data

    Are these concurrent programs custom or seeded? You're correctly concurrent managers? Please see these documents for more details.

  • One to many with several tables on one side and a table on the side "several."

    Sorry for the confusion in the title. Here's my question. In my program, I have 2 different tables that store the 2 different types of entities. Each entity has a list of attachments that I stored in a table of common attachments. There is a one-to-many relationship between the entity and the attachments table tables.

    () ENTITY_ONE
    ID
    NAME
    )

    () ENTITY_TWO
    ID
    NAME
    )

    ATTACHMENTS)
    ID
    ENTITY_ID
    ATTACHMENT_NAME
    )

    ENTITY_ID of attachments table is used to link the attachments to the one entity or two entity. All codes are generated by a single sequence. Thus, they are always unique. My question is how can I map this relationship in the EntityOne, EntityTwo and attachment JAVA class?

    For EntityOne and EntityTwo, you can simply define a normal OneToMany mapping using the foreign key.
    You use the TopLink API or APP? JPA requires a mappedBy to the OneToMany, so this may be more difficult. You should be able to simply add a JoinColumn on the OneToMany and make the Insertable/editable = false column.

    To fix, you could either map the foreign key as a Basic (DirectToFieldMapping) and maintain in force in your model or use a VariableOneToOne to TopLink mapping (this will require a common interface on behalf of entities).

  • Multimaster replication tables

    Hi all
    Just the Question:
    I have two tables that second is the first clone; I have therefore two paintings that they are one copy of the other.
    I would like to replicate all the changes first in the second and all the changes from the second to the first, so forbidden triggers.

    I think at one of the tables of a materialized view in the other table, replacing them with reflresh on commit so all changes to the table to watch would be spread to the MV.
    But my question/problem is how to propagate changes to the MV in the main table.


    Any ideas?
    Thanks in advance

    So, if your web application is to write in this way that they manipulate directly two tables with identical data you have to cheat a little.
    Do not create a MV, but create view on main table as 1:1.
    Then create instead of trigger for insert, update and delete on sight and this do nothnig trigger.
    Suppose that next view my_view triggers code call me

    create or replace trigger tg_donothing instead of insert or update or delete on my_view
begin
null;
end;
/

    So now when perform web aplication DML against table main DML is done. When the web application perform the same operation on DB do nothnig my_view.
    There would be a single problem if web aplication cechk SQL % ROWCOUNT to find out how many rows were affected and compare it with SQL ROWCOUNT % against actual table.
