ODI not able to detect primary/foreign keys from XML- user lacks privilege or object not found

Hi Guys,
Im trying to load an xml file with two entities address and employee as below. The topology reverse engineering everything works fine. Im even able to view the xml data in ODI, but when i try to load the data from these two entities joining by the schema primary keys and foreign keys which odi created on reverse engineering process for xml, im getting the below error. Im able to load data from one entity, error only occurs when i use the join odi creates internally to identify the xml components employee and address
XML File:
<?xml version="1.0" encoding="UTF-8" ?>
<EMP>
<Empsch>
<Employee>
<EmployeeID>12345</EmployeeID>
<Initials>t</Initials>
<LastName>john</LastName>
<FirstName>doe</FirstName>
</Employee>
<Address>
<WorkPhone>12345</WorkPhone>
<WorkAddress>Test 234</WorkAddress>
</Address>
</Empsch>
</EMP>

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.

Detect the fields which are primary/foreign keys for each schema's tables

Hello everybody,
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

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.

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

Create a foreign key from a field that is part of a mulitple primary key

Hi,
i had a table named T_A, with a double primary key : (A,B)
Then i created a table named T_B with a field : C.
I want this field T_B.C to take only values that already exist in field T_A.A.
So i tried to create a foreign key on my field T_B.C, pointing on the field T_A.A : an error message appeared "not possible to create a foreign key on a field that is not a primary key".
How can i solve this....? If U have any idea, please mail me !!
THANX very much.

Add column A as foreign key into the table T_BHow?
(was the question from the original poster. Adding a column to table T_B that happen to have same name as the corresponding column in table T_A would not allow you to add the foreign key).
SQL> create table t_a (a number, b number, primary key(a, b)) ;
Table created.
SQL> create table t_b(a number, c number, constraint foreign key references t_a(a)) ;

Java aplication not able to detect card reader sometimes

Hi
We have a Java application (jre1.6.0_05.) which runs as window service under "Local System". It tries to detect card reader after every one minute. Normally it is working fine. However on some machines (which can be Windows XP, 2003 Server etc) some times it is not able to detect Card Reader, while other applications (which are not Java based) are able to detect. Sometimes service restart helps in solving the issue, but it reoccurs again after few hours/days.
Below is the exception we get:
javax.smartcardio.CardException: list() failed
at sun.security.smartcardio.PCSCTerminals.list(PCSCTerminals.java:109)
at javax.smartcardio.CardTerminals.list(CardTerminals.java:55)
Below is the code we are using to get list of terminals:
TerminalFactory factory = TerminalFactory.getDefault();
try {
terminals = factory.terminals().list();
} catch (CardException e) {
e.printStackTrace();
}Any idea what might be causing this random problem?

Hi,
According to the source for OpenJDK 6 (b19) the only way to get the exception you posted was with a PCSCException being thrown with the root exception wrapped in the new exception.
// from PCSCTerminals.list(State state)
try {
// do some stuff to get the reader list
} catch (PCSCException e) {
throw new CardException("list() failed", e);
}If this was not the case in the version you have, you will definitely see the root cause with the new JDK.
Cheers,
Shane

Just purchased a new mac mini 3GHz Intel Core i7, with 16GB ram version 10.10.1. With it i purchased a new wireless keyboard. All of a sudden I was not able to use the #1 key. I thought I had a defected newly purchased keyboard. I pulled out my older wireless keyboard, and the same thing happened. It must not be the keyboard if it happened to two different keyboards. I have a habit of restarting my computer, when things don't work, I find it helps, and sure enough, everything works. Today, it happened again. Does anyone know what is causing this to happen?

How to remove foreign key from table?

i want a query from which i will remove foreign key from the table. plz help me in it. the table is created as follows:
CREATE TABLE cw06_course
     (coursecode NUMBER(4) CONSTRAINT coursecode_pk PRIMARY KEY,
     department NUMBER(4) CONSTRAINT course_department_nn NOT NULL,
     coursename VARCHAR2(25),
     courseleasder NUMBER(4),
     CONSTRAINT course_department_fk FOREIGN KEY (department) REFERENCES cw06_department(deptno));

parent keys not foundWell, while the constraint was not available (dropped), someone took the opportunity and inserted rows into your child table that do not have a corresponding value in your parent table.
Why was the constraint dropped in first place? why did you give someone the opportunity to insert constraint violating value into the table?
You must either:
1). remove the child rows not found in parent
2). create parent rows fr missing child rows.
3). enable novalidate the constraint so existing values can remain without parent but future rows must confirm.

Remote Object - not able to get the returned value from java method

     Hi ,
I am developing one sample flex aplication that connects to the java code and displays the returned value from the
java method in flex client. Here I am able to invoke the java method but not able to collect the returned value.
lastResult is giving null . I am able to see the sysout messages in server console.
I am using flex 3.2 and blazeds server and java 1.5
Here is the code what I have written.

    <scope>application</scope>
   </properties>
</destination>
Please help me .

You are not able to get the returned value because if you see the Remote object help you will realise you have to use result="resultfn()" and fault = "faultfn()"
In this you define what you wish to do.
More importantly in the remote object you need to define which method you wish to call using the method class like this
<mx:RemoteObject id="remoteObj" destination="sro" result="r1" fault="f1" >
     <Method name="javaMethodName" result="r2" fault="f2"/>
<mx:RemoteObject>
r2 is the function where you get the result back from java and can use it to send the alert.
