Primary / foreign key replication

Good Day,
Suppose  we have a Warm Standby , ASE 15.5, RS 15.6 with several databases pairs and table cross reference between these different databases, i.e:
Pdb1 -> Stdby1
Pdb2 -> Stdby2
PdbN -> StdbyN
Table T1 is at Pdb1 , table T2 is at Pdb2
T1 has  a Pkey  , T2 has  a Fkey  to PKey on T1( for example a master / detail relation ship) 
and so on
Some times due to network latency (or other event)  table T2 gets replicated before than T1 and replcation stops due to primary constraint violation, even though the PK exists on T1 ( but hasn't been replicated yet).
Q: Is there any way to ensure that T1 would get replicated first in order to avoid the error?
Thank you
Regards
Jose-Miguel

  • Query Builder recognizing primary/foreign key

    Is there a way to have Query Builder recogninze the primary/foreign keys of the tables when they are selected? Right now it looks like you have to manually join the tables together by selected the column(s) to join.
    Thanks

    You can define a query key[1] 'planId' on InvestmentOption for the PLAN_OID column. That'll let you write an expression like the one below which does not produce a join. The nice part about the query key is that it does not require you to add attributes to your object in order to query o them.
    Expression plan = new ExpressionBuilder();
    Expression where = plan.get("planId").equal(somePlanId);--Shaun

  • Missing primary foreign key in grandchild table

    I have a model with a two inheritance generations.
    https://www.dropbox.com/s/4rghqcmxx24bgvt/pf_logical.png
    When I engineer all entities everything is fine. The child tables get their primary foreign keys:
    https://www.dropbox.com/s/t4v5bexxwdrn5y1/pf_engineered.png
    But when I do not engineer the child generation the grandchildren have no primary foreign keys anymore.
    https://www.dropbox.com/s/ofl436sm8dua3w8/pf_missing.png
    I have expected, that the grandchildren get a primary foreign key to the grandfather. But that is not the case. How can I tell the modeler to engineer such a foreign key?

    Hi,
    thanks for reporting the problem. I logged a bug for that.

    Thats obvious from the xml file contents you have given here. In this xml file You have four complex type. Two of them are employee and address. However the employee doesnot have any relation with address as you have not added the relationship. Thats why its failing. Its not the fault of ODI.
    Also I would suggest not to use auto generated dtd by ODI as you might face problem in future. For example the address type of XML has 8 attributes and 4 of them are not mandatory. That means each of your xml file may have attributes between 4 to 8.  This is where ODI auto generated DTD fails.

  • Caching problem w/ primary-foreign key mapping

    I have seen this a couple of times now. It is not consistent enough to
    create a simple reproducible test case, so I will have to describe it to you
    with an example and hope you can track it down. It only occurs when caching
    is enabled.
    Here are the classes:
    class C1 { int id; C2 c2; }
    class C2 { int id; C1 c1; }
    Each class uses application identity using static nested Id classes: C1.Id
    and C2.Id. What is unusual is that the same value is used for both
    instances:
    int id = nextId();
    C1 c1 = new C1(id);
    C2 c2 = new C2(id);
    c1.c2 = c2;
    c2.c1 = c1;
    This all works fine using optimistic transactions with caching disabled.
    Although the integer values are the same, the oids are unique because each
    class defines its own unique oid class.
    Here is the schema and mapping (this works with caching disabled but fails
    with caching enabled):
    table t1: column id integer, column revision integer, primary key (id)
    table t2: column id integer, column revision integer, primary key (id)
    <jdo>
    <package name="test">

    Because the ids are known to be the same, the primary key values are also
    used as foreign key values. Accessing C2.c1 is always non-null when caching
    is disabled. With caching is enabled C2.c1 is usually non-null but sometimes
    null. When it is null we get warnings about dangling references to deleted
    instances with id values of 0 and other similar warnings.
    The workaround is to add a redundant column with the same value. For some
    reason this works around the caching problem (this is unnecessary with
    caching disabled):
    table t1: column id integer, column id2 integer, column revision integer,
    primary key (id), unique index (id2)

    Needless to say, the extra column adds a lot of overhead, including the
    addition of a second unique index, for no value other than working around
    the caching defect.

    Tom-
    The first thing that I think of whenever I see a problem like this is
    that the equals() and hashCode() methods of your application identity
    classes are not correct. Can you check them to ensure that they are
    written in accordance to the guidelines at:
    http://docs.solarmetric.com/manual.html#jdo_overview_pc_identity_application
    If that doesn't help address the problem, can you post the code for your
    application identity classes so we can double-check, and we will try to
    determine what might be causing the problem.

    I'd like to know if it's possible to select a field in one of the dictionary tables to identify the fields of a table which are PK or FK in this one. I'd like to do this to generate the fields that I need to put in a technical design.
    Actually I have this (if it can help you to understand what I'd like to do) :
    select table_name "Table name",
    column_name "Physical field name",
    case when data_type = 'NUMBER' then data_type || '(' || NVL(data_precision,0) || ',' || NVL(data_scale,0) || ')'
    when data_type = 'VARCHAR2' then data_type || '(' || data_length || ')'
    else data_type
    end "Datatype",
    case when nullable = 'Y' then 'FALSE'
    when nullable = 'N' then 'TRUE'
    end "Not null",
    /* Here I'd like to retrieve TRUE or FALSE if the field to display is a primary key or not and the same for foreign keys*/
    from all_tab_columns
    where table_name in (select table_name
    from all_tables
    where table_name like '%project_name%'
    and table_name not like '%TMP%');
    Thanks a lot for your help,
    Florent

  • Primary - Foreign key

    hi
    oracle 10.2.0.1.0
    when there is foreign key then there should be corresponding column with either primary key / unique key constraint. Why is this rule aprt from normalization rules to make one Relational-DB
    please help
    like sample
    customer table - customer id.
    Account table - account id , customer id .
    Address table - Adress id , address line1.for sake of unique identification of an unique tuple ? is it all to sum up ?

    Hello again,
    May be I was not clear enough.
    Scenario 1: We use the master-detail form as is with the default oolbar. In this case, the user can insert the detail records one by one without needing the primary-foreign key value since this is handled by default.
    Once we save the form (commit_form), I use the pre-insert trigger to get the master block primary key generated from the sequence and since the detail block key is copied from this value, both are saved correctly and it is the end of the story.
    Scenario 2: As explained in the initial post, the user will populate the detail records one by one by clicking on the -INSERT DETAIL- button and hence has a window where he can insert the detail info and then be brought back to the master-detail form every time he enters a new detail record.
    The problem here is that I can't generate the primary key for the master block since the client has the following requirement:
    The user can always change his mind and not complete, meaning save the form, his process
    As such, the key should be generated in the last step before Commit.

  • Copying tables that have Foreign Keys

    All my tables are using primary/foreign keys. If you look at the example below, I have a table 'stu_school' which has 3 foreign keys (FK_YEAR,FK_SCHOOL,FK_GRADE_LEVEL) pointing to 3 other tables. Every year I need to create a new record in the year table and copy the data from the previous year (with the FK_YEAR value) into the new year. Is there a better approach to moving this data over other than manually writing SQL statements and making sure they are done in the correct order (becuase of the keys).
    stu_school
    PK_ID
    FK_YEAR
    FK_SCHOOL
    FK_GRADE_LEVEL
    year
    PK_ID
    YEAR
    school
    PK_ID
    SCHOOL
    grade_level
    PK_ID
    FK_YEAR
    FK_SCHOOL
    GRADE_LEVEL

    Since this is going to be an annual task and should therefore be part of the application I suggest writing a pl/sql script that performs the necessary actions rather than use sql to generate the sql to perform the action. A pl/sql script would allow better activity logging and error handling appropriate for a repeating production task.

  • Mapping in OWB with primary key and foreign key relationship

    Hi all,
    I am new to this datawarehousing field. I have just started my career. I have to now create a mapping in owb where a table has a field which is a primary key of another table in the same staging area. If you guys could help me out with the a method it can be created that would be very helpful to me.
    I thought of 2 ideas,
    1. If I can use a look up, but then I am not sure if i can use a lookup for primary key, foreign key relationship. If I can use also, I do not know how to use that.
    2. What if I can directly take that the first table and link the primary key of that table to the second table which uses that primary key of the first table as one of its fields.
    I do not know how feasible these methods are. Please guys help me out.
    Thanks in advance.

    I have a similar case where table a and table b having relation but table a got inserted with data and table b is empty so there no values for foriegn key column in table b to realte with table a.
    Now i want to load table b foriegn key with primary key column values of table a.
    how can we do this in owb
    thanks

  • CMR - Can a primary key also be a foreign key?

    Hi,
    Has anyone come across the following problem? Although I mention Jdeveloper below I believe it is a general J2EE issue!
    I have two tables
    customer
    customer_id (PK)
    individual
    customer_id (PK)
    customer_id in individual is the primary key for that table. It is also a foreign key ( related back to customer).
    If I use JDeveloper to drag in the two tables ( into a class diagraqm), I have a problem.
    JDeveloper "sees" the Individual bean foreign key mapping and generates a getCustomer() method (which returns a handle to the appropriate customer bean).
    However as it "removes" the getCustomer_id() method(which returns the actual customer_id), the primary_key reference is dropped.
    When I try and compile, JDeveloper quite rightly complains with "where is the primary key".
    Can anyone help? Do I need to make it a rule that the foreign key is not also the primary key?
    thanks in advance,
    Kevin

    Hi Kevin,
    I would not pursue this model if I was you. The only thing OC4J supports without killing yourself is to let each table has its own primary key (preferably not composed) and to make all foreign key's optional !
    We have spent months trying to make it work and we are getting little or no support from oracle, even though we are paying many euros for a partnering contract.

  • FOREIGN KEY IS PRIMARY KEY

    Hello,
    I am having the same problem attempting to use a foreign key as a primary key in an EJB 2.0 CMR running on WLS 6.1. If I do not set the foreign key portion of my composite key in the ejbCreate() method I get an error stating that the field cannot be null (and must be set), when I set the field in the ejbCreate I then get an Error in the ejbPostCreate stating that CMR fields cannot be set using the setXXX methods. The entity relations are as follows:
    SalesOrder <--------------------------------------->SalesOrderProduct
    SalesOrder = (orderid(PK)+orderstatus+salesrepid+contractdate+processdate)
    SalesOrderProduct = (orderid(PK/FK)+productid(PK)+qty+unitcost)
    The CMR relationship is bi-directional. The SalesOrder entity bean's ejbPostCreate() method
    invokes a helper method that attempts to create the salesOrder product entity as part of the salesorder create transaction and that's when I get the errors stated above.
    Have or anyone found out how to handle this kind of cmr using the Weblogic server (6.1) and ejb 2.0??
    Thanks,
    Darryl
