Mapping to different databases
We currently use TOPLink as persistence layer in our product. Currently the complete object model maps to one database. I was wondering if it is possible to map different objects to different physical databases (with different structures). E.g. We map the income object to a certain table in db1 (database only containing income data) and the investment portfolios to another database; etc.
Does anybody has experience with this? Thanks for your reply.
Hi,
In order for you to work with two different databases at the same application you will need to use Session Broker.
You can find an example of doing such a thing under "D:\toplink903\examples\core\examples\sessions\broker".
In addition, you can find a large section in the 'TopLink foundation library' about the subject.

Reusability of mapping with different database
Can i reuse the ODI mappings within different database.. like DB2,Oracle10 g, Oracle 11 g.
The table name should same in all the environment.I am not saying I am 100% correct. As per my interpretation i believe it will work between oracle 10g to 11g. But not sure if it is db2. You might have to change the KM.
Just check with the generic KM. That might help you which normally works with all rdbms. -
How to create a view consisting of data from tables in2 different databases
Using Oracle 10.2g
I have 2 databases Gus and haggis on Comqdhb schema.
glink indicates a databse link between Haggis and Gus
In Gus there are tables student,subject,grade,school containing columns like upn...
STUDENT
upn
academicYear
SUBJECT
subject
GRADE
examlevel
grade
SCHOOL
sn
In HAGGIS there are tables student,grade,teacher containing columns upn...desc below.
STUDENT
upn
GRADE
grade
upn
academicyear
level
Create view in your HAGGIS database which will join all of the exam grades together. You should have one view which will produce the following relation :
examGrade(upn, subject, examlevel, sn, grade,academicYear)
so I need to create a view which gets the data from both the tables in both the databases.
create view as examGrade(upn, subject, examlevel, sn, grade,academicYear) as select s.upn
But i am not getting how to select a column from 2 tables in different databases
I mean if i said
select upn from comqdhb.student@glink,comqdhb.student;
select upn from comqdhb.student@glink,comqdhb.student
ERROR at line 1:
ORA-00918: column ambiguously defined
help me out,Thank you.Thank you for the reply will follow up the code format
Create views in your HAGGIS schema database which will join all of the exam grades together. You should have one view which will produce the following relation :
examGrade(upn, subject, examlevel, sn, grade,academicYear)
I understand that there wont be duplication when we use conditions
If i query
select count(upn)
from comqdhb.student@glink I get 9000
but after the union
create view examGrade(upn, subject, examlevel, sn, grade,academicYear)
as
select distinct s.upn as upn
, g.subject as subject
, g."LEVEL" as examlevel
, g.grade as grades
, '9364097'

Another problem i am having which i am trying to solve and written up my ideas but haven't been getting the expected results.Hope you can help.Thank you.
Information:
=======
All children take exams at the age of 16 called a General Certificate of SecondaryEducation (GCSE).
They have to study and take exams in Mathematics, English and Science, and can take other subjects such as History, French, Art etc. Most students will study between 5 and 10 different subjects before taking their GCSEs.
For each exam, a student is awarded a grade from A*, A, B,C,D,E,F,G,U,X An A* grade is the best grade achievable and an X is the worst grade.
In order to analyze how students have performed, each grade is mapped to a numeric value as follows:
Grade Numerical score
A* 8
A 7
B 6
C 5
D 4
E 3
F 2
G 1
U 0
X 0
Now why i need this avgGCSE is because i have to create a view containing avgGCSE of the students it is used in the next question where a condition is avgGCSE is between 6.5 and 7
In order to calculate the avgGCSE the idea is to calculate the grades of the students and map the grades to their corresponding scores/values
add them all up and div by the total no of grades to get the avg.

I have a opinion that xgcse in STUDENT table refers to the avgGCSE which i want to calculate as when i asked my professor as to what xgcse he said that he forgot to take it out of the table and it is not necessary while creating avggcse.
select *
from comqdhb.student@glink
where xgcse<6.5; Displaying a result
returns:

returns:

===========================================================================
1386 STEPHANIE AANNESSON 15-JAN-79 f none 6.88873 2 2 so if xgcse is the avgGCSE then upn 1011 has avggcse<6.5 and 1386 has avggcse >6.5
my idea was backward strategy like so now if we find out upn 1368 has suppose xgcse(avggcse)>6.5 how to extract the avggcse for the particular upn We need to map grades from GRADEVALUES to grade in STUDENTINGROUP and map upn from studentingroup to upn in student to output the values for the corresponding grades from GRADEVALUES
select grade
from comqdhb.studentingroup@glink
where upn = 1011;
Result:

=====

8 rows selected. Mapping each grade to the corresponding value and calculating we get
32/8=4 total(values to corresponding grades)/no of grades.
But the xgcse for upn 1011 is 3.935 and i am getting 4!! maybe xgcse isn't avggrade but ? is the procedure by me correct for calculating avggcse
select grade
from comqdhb.studentingroup@glink

Result:

Can I use two different database with DBSystemLoginModule?
Finally I can login with Database user id by DBSystemLoginModule on Embedded oc4j server.
But I confused between [b]jazn-data.xml and system-jazn-data.xml.
Which xml do I have to edit for jdbcUrl and jdbcDriver?
Now I would like to use two different database(such as only sid is different).
In this case I want to show specific database name as realm name.
What should I do?
When I use DBSystemLoginModule, I edit JdbcUrl in system-jazn-data.xml.
So can I pass the parameter for sid programmatically?
And also I tried to run my application with other database with DBSystemLoginModule on Embedded oc4j server.
I changed few things(jdbcUrl at system-jazn-data.xml,jazn-data.xml in embedded-oc4j-server/config and database connection for BusinessComponents at Project Properties of Model/ViewController.
But I got some error.
Did I miss something?

Deployment to runtime repository in different database hangs
Hi All
I am facing an issue while deploying to a runtime repository in different database.
I have created a simple mapping,taking data from one schema available in database where OWB is installed, to schema available in different database.I am changing the configuration to the control center available on target database.
source module is associated with control center available on design repository and target module is associated with control center available on runtime repository.
In control center manager,the message displayed at toolbar is "compiling deployment object"..after sometime OWB hangs and nothing happens.
What could be possible reason for that?
Thanks in advance
AvanishI got the problem with OWB 10.1.0.4.0 and I had to install the path 10.1.0.5.0 for make it works !

Joining tables in different databases
Hi,
I know we can access multiple databases like Oracle, Informix etc. through a single toplink session using session broker. Also in toplink documentation it says there is a work around for joining tables that exists in different databases i.e. joining an Oracle table with an Informix Table. If anyone had tried this or if it is possible, please let me know how to do this.
Thanks..If I could know, how to perform or some sample code, for the following two steps it would be great.
Write descriptor ammendment code to bind together that go from (A) to (B) and (B) to (A).
Be sure to map the ammendment descriptors in the mapping workbench.Or please point me to the right toplink documentation or examples.
Thanks a lot for your help. -
Different Database structure migartion
In second version of our software we change the database structure.
Now we need to migrate data from version 1 to version 2 that have different database structure.
Is Streaming or any other oracle feature provides possibility or I should write code by hand?I sugeest you migrate the tables individaully having in mind the DML and DDL statements
hitting the database from the application end. You need to do a mapping for both the databse.
Do the events from your old application still update the same tables as the new application
You need to really think this out to avoid having complications in your new version.
I dont think stream option is the best at this stage rather export/import of tables would be the best option
then you can think of stream to update your new version at run time. -
Persisting Entities in different databases
Hello! In our compony we need to store information in two different databases. To check if this is possible I've written a simple program, in which part of the entities is stored in one DB, and the other part - in another. And I have an error during deployment whith the following stack trace:

@Entity
public class SalesLineItem implements Serializable {
private int quantity;
private Specification productSpec;
private int id;
private Sale sale;
@OneToOne
public Specification getSpecification() {
return this.productSpec;
}And here's my persistence.xml:

</persistence-unit>
</persistence>Then, I suppose, I create two EntityManger is session beans, each associated with one specific persistence unit.
When I use one database (one pesistence-unit in persistence.xml), everything works fine. I wonder, if it's possible to persist entities in a such way that entities with relationships between them are stored in different databases. Any help is greatly appreciated.If I could know, how to perform or some sample code, for the following two steps it would be great.
Write descriptor ammendment code to bind together that go from (A) to (B) and (B) to (A).

How can I connect to a different database schema,other than adobe?
I'm building an application where I want to use a different database for it,for storing additional data for the users(different from "edcprincipaluserentity" table in "adobe" database stores)..How I can connect to my database schema created in MySQL from Workbench,to assign tasks to my users,using the Process Management/Assign Task service?
You can only assign task to user that are known by the LiveCycle User Manager.
When you configure LiveCycle, you can tell it where you want to get the users from. They can be created them locally in the local database, or synchronized from an LDAP directory in which case it'll read the users from LDAP and make a copy of some of the properties to the internal LiveCycle database.
Bottom line, all users have an id (in the edcprincipalentity table) in the adobe database.
If you need your users to come from a different database, then you need to customize the SPI (security provider interface) so that you can synchronize the users coming from your external database. Again, this is a customization since out of the box, we don't synchronize against external database. But it is possible, the API is there and other customers have done it.
I hope this clarifies things a bit.

APEX Application accessing data from two different databases
Hi All,
Currently as we all know that APEX Application resides in database and is connected to the schema of that database.
I want APEX Application to be running and accessing data from two different databases. Elaborating my question,
Currently, my APEX Production Application is connected with XXXX Schema of DB1 Database(Where APEX Resides). Now I want to add some pages into this APEX Application for REPORT Purpose, But I want to connect this REPORT APEX Pages to get data from Different Schema YYYY for Database DB2.
Is it possible to configure this scenario?
The reason for doing this is to avoid the REPORT related (adhoc queries) resource utilization effect on Production DB1 Database.
Thanks
Nil1. If you do the joining of two or more tables in DB1 then all data is pulled over to DB1 and then the join is executed: so more data over the databaselink and more work for DB1. Better keep the joining stuff where the data resides and just pull exactly that data over that you need.
2. Don't know about your different block sizes. Seems a nice question for one of the other forums (DBA or SQL).
3. I mean create synonyms on DB1 for reports VIEWS in DB2.
Hope all is clear! -
JMS JDBC store failed to open after switched to a different database machine
Hi,
I'm running WebLogic 6.1 sp3/Oracle 8.1.6 and I configure the JMS JDBC store for
persistent messaging. I was working fine until I switched to use a different database
machine which has the same software configuration as the old one. It was giving
me "failed to create tables" error at start up time. But I checked the database
and found out the two tables (<prefix>JMSSTORE and <prefix>JMSSTATE) were both
created and I was able to query although they don't contain any data. By the way,
I'm using thin client.
Anyone can help? Thanks a lot!

Hi Michelle,
I suspect a permission problem where the new tables are created
using the JDBC driver's default schema, but the prefix
specifies another schema "qa". So the tables are getting
created, but aren't found.
Work-around one:
manually extract, edit, and run the ddl that creates
the tables to specify the schema. Prepend
"qa.JMS_SERVER_" to all table names
(This is fairly simple to do.)
http://edocs.bea.com/wls/docs61/jms/appb.html#999286
Work-around two:
Don't include "qa." in the prefix.
(i'm not sure if this will work)
Work-around three:
Change the username of the JDBC pool to "qa".
(i'm not sure if this will work)
Work-around four:
Change the schema for the tables that were created
under the JDBC driver's default schema to "qa".
(I'm not sure how this is done, or even
if it is possible. Database specific.)

Can we use different Databases (Oracle & SQL Server) in one report?
Post Author: venki5star
CA Forum: .NET
Hi there.
Can we use different databases (Oracle & SQL Server) in a same report?
If possible how?
Another question,
Can we change the Provider Name at runtime of the given report. If so the above question is useless...
Thanks in Advance.I tried this using Oracle Provider for OLEDB (the one that supplied by Oracle Client) and Crystal Reports 9. you can drag the column into designer but the image does not appear in preview.
I guess it's because CR does not recognized it as image, and there are no information that the blob data is an image at all. -
How to add two different database connections on Model
Hi,
In my application, I need to create View Objects on different databases. So I need to add two different database connections on the Model.
But it seems like Model can be connected to only one database. I tried adding another project to add the second db connection. But after I created a read-only View Object in the second project, it didn't generate corresponding data control in the Data Controls panel.
Could anyone help me on this?
Thanks!Do you mean adding the second project folder in ViewController->Project Properties->Libraries and Classpath?Yes, either that or: ViewController -> Project Properties -> Dependencies
And I didn't see the first Model project in the ViewController classpath. Otherwise it wouldn't work. The first model project IS in 'classpath'. Here's how:
ViewController -> Project Properties -> Dependencies
I tried this and recreated the View Object. Still didn't generate the datacontrol. No idea why you had to recreate the VO.
Is your VO in an application module inside the SECOND project?
After you are sure that everything is in the ViewController's classpath, just try restarting JDeveloper.
This is very basic. has to work. -
How to use %Type declaration with table residing in a different database
How can I use the %TYPE declaration if the table is from a different database.
E.g
v_business_unit ps_jrnl.header.business_unit%TYPE;
In the above declaration statement,the table 'ps_jrnl_header' resides in a different database(Database A) from the one I am currently in( Database B).(This is because data needs to be extracted from Database A into Database B).1. Create a database link to the other database (this probably already exists since your proc is interacting with that database)
2. Create a synonym for the table in the other database
create synonym foo for ps_jrnl.header@database_a;3. Reference the synonym in your variable declaration:
v_business_unit foo.business_unit%TYPE; -
How to host one application using different database connection on OAS?
Hi,
Jdeveloper - 10.1.3.4
Application - ADF/BC
Oracle Application Server - 10.1.3
Above our the specifications for our application,
We have two database schemas different for development and production therfore we have different databse connections for the two,
we have one application which is in production and enhacements on the same application are done by the development team.
Since we have two different schemas for developement and prduction we use different database connections for the application on development and production.
The problem is our Model and View Controller project are same, only the database connection file changes that's why we are able to host only on application at a time on our OAS. This is probably because the URL generated by OAS for developemnt and prodyction application is same.
Is there a way we can host two instances of the same application with two different database connections on the a single OAS.
Thanks & Regards,
