OAF Page to connect two different Databases

Hi OAF Team,
We have a requirement to connect another instance from the source instance. That is when we login via supplier user for Supplier portal access we also need to see the planning details availble in another instance(database).
All the pages in the Supplier portal and collaborative planning are of OAF pages.
Also need to login once only, That is when we are into one instance and if we provide the hyper link of other instance in the home page, is that possible to connect the other database by defaulting the login/pwd from source login.
Regards
Vish

Hi, I am too intersted in knowing if it is possible to use a remote database objects other than the default one. There was some guideline present for using it on SQL Server. I followed similar approach but it gave table or view does not exist error while running from JDEV.
Apreiciate any help this.

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.

Connecting to two different database instances from a swing application.

Hi All,
I am developing a swing application which needs to interact with two different database instances of two different weblogic servers.
More eloborately,
I have some data in DB_Instance1 running on[b] Weblogic_Server1 and I need to insert the same data into DB_instance2 running on Weblogic_server2. Is it possible. Could some explain me how to do that..
Thanks in advance...
Sreekanth.

Hi Rick,
Try logging onto both Server first. You'll have to use either 2 separate ODBC DSN's or 2 separate OLE DB connections. Set them both for Trusted Authentication, you'll have to configure that on the Server also.Then try your query.
If that doesn't work then you'll have to create a Stored Procedure or View that can link the 2 Server side.
Thank you

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
Nil

1. 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!

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?

I think I understand now, you are modifing the custom login modules configuration within the system-jazn-data.xml file. This is a bit dangerous! Didn't you register the login module in your orion-application.xml? For example, this is the way I do it:
<web-module id="customProv-web" path="customProv-web.war" />
<persistence path="persistence" />

<security-role-mapping name="sr_developer">
<group name="developers" />
</security-role-mapping>
<security-role-mapping name="sr_manager">
<group name="managers" />
</security-role-mapping>
<jazn provider="XML">
<property name="custom.loginmodule.provider" value="true"/>
<property name="role.mapping.dynamic" value="true"/>
<property name="role.compare.ignorecase" value="true"/>
</jazn>

Open two Forms Connecting Two different Data bases simultaneously.

i am facing a problem for opening two forms in two different SAPB1 applications where it is connecting into two different databases.please send me a solution for this problem.

Hi Hareen,
What is your goal to design a form for connecting 2 databases in the same time?
Thanks,
Gordon

Open two Forms Connecting Two different Data bases

In The Same Company Two Different Places Open Same SAPB1 Application Connecting with Two different DataBases,Open both two forms same time.

Hi Mai,
you can always open multiple forms in a company.so if you want to open one form from Database 1 and Database 2 , then its okay. If I did not answer your question correctly, then kindly explain your question in a more detailed way.

How to handle transactions when two different databases are involved.

consider two tables namely Table-A and Table-B part of two different databases namely ORACLE and MYSQL.
Now the project requirement is updating the Table-A(ORACLE) and Table-B (MYSQL) as one transaction. i.e. either update both the tables or rollback both the tables.
Now my question is how could i handle this situation using JDBC(Type-4) driver.Because i think at a time only one JDBC driver can be loaded into the JVM.

NareshAnkuskani wrote:

But anyway, you need to use distributed (XA) transactions. i believe that the latest version (5.0) of mysql actually has support for XA transactions. you need to use a to setup a distributed transaction and attach the connections for the two databases to that transaction. then it should function as you desire.

Synch Between Tables in Two different Databases

Synch between Two Tables in two different Databases.
I have two identical tables, table T1 in Database D1 and table T1 in Database D2. User can insert/update/delete/select from both of these tables in respective databases. Being said that how can keep them in Synch? Any thing added/modified/deleted should reflect in other. We like this to be Real-Time.
We are thinking of creating a cross (two way) DB link between them and then update/insert/delete both the tables when changing one. Any suggestions?
Thanks

One of my colleagues used snapshot in their previous projects, but he told me that the performance of it wind down while the records in tables increase. I have no idea about the exact situation, but I'm believing we'd think twice about it.

Compare performance of two different databases...idea of a report to us?

Dear Colleagues,
We would like to compare the performance of two different databases running with SAP. We don't want to start with Loadrunner. We are looking more for some ABAP program which generates a lot of load on the database and then would just run the program on both databases. Any idea for a good report? We thought about sgen, but we think this is taking more into account the application server instead of the database.
Regards,
alexander

Hello,
If you are not willing to use tools like HP Loadrunner or IBM Rational performance testing
SGEN could be an option. It is quite intensively using the DB. It will be hard to find a report that only perform DB access.
SGEN at least allows to test read (REPOSRC, DYNPSOURCE...) & write (REPOLOAD, DYNPLOAD...). If the DBs are on the same servers as the SAP system and both servers has the same power it can be a good way to test.
Best regards

Comparing Tables In Two Different Databases

Hi,
As part of our project, we need to perform table comparisons in two different databases. I am currently looking for various options to accomplish this.
One of them is doing minus operation between these two tables.
Also, i have looked at the data compare option in toad utility.
Please suggest me any other options that makes my job easy.
Thanks in advance,
Sue

Then just adapt the select that is there
SELECT stid , c1, c2, c3
   FROM
( SELECT a.*,
         1 src1,
         to_number(null) src2
   FROM a
   UNION ALL
   SELECT b.*,
         to_number(null) src1,
         2 src2
    FROM b
   GROUP BY stid , c1, c2, c3
   HAVING count(src1) count(src2)
   order by stid;Best regards

CONNECTING FORM WITH TWO DIFFERENT DATABASES

HELLO ALL
Is there any way I can connect to 2 different databases at the same time. What I have is 2 different database for two different payroll systems. Now what I want to do is if user press a button I send some data from this payroll database to second payroll database using insert and update command.
I am using Form 5, one database is Personal Oracle 7 and second is Oracle 7.3. (I don't think versions matters but anyway)
Thanks

Hello,
Yes u can connect to with several database at a time using ODBC connection and Exex_Sql package supplied with Forms6i as a built-in. There is no Exec_Sql built-in supplied with Forms5, but there is a library named exec_sql.pll (Check it out) supplied with Forms5.
using this package u can connect with multiple DB at the same time.
here is an example-
Declare
v_ConnHandle Exec_Sql.ConnType;
v_CursHandle Exec_Sql.CursType;
v_NumRows Pls_Integer;
Begin
v_ConnHandle := Exec_Sql.Open_Connection('Scott', 'Tiger', 'ODBC:DBName');
v_CursHandle := Exec_Sql.Open_Cursor(v_ConnHandle);
Exec_Sql.Parse(v_CursHandle,'Select ename From emp');
Exec_Sql.Define_Column(v_ConnHandle, v_CursHandle, 1, v_EmpNAme);
v_NumRows := Exec_Sql.Execute(v_ConnHandle, v_CursHandle);
While Exec_Sql.Fetch_Rows(v_ConnHandle, v_CursHandle) > 0 Loop
Exec_Sql.Column_Value(v_CursHandle, 1, v_EmpName);
End Loop;
Exec_Sql.Close_Cursor(v_ConnHandle, v_CursHandle);
Exception
When Exec_Sql.Package_Error Then
If Exec_Sql.Is_Open(v_ConnHandle, v_CursHandle) Then
Exec_Sql.Close_Cursor(v_ConnHandle, v_CursHandle);
End If;
Message('Error ('| |Exec_Sql.Last_Error_Code(v_ConnHandle)| |') : '| |Exec_Sql.Last_Error_Mesg(v_ConnHandle));
End;
hope this help you.
best of luck.
