Multiple DataBase Connection in a Single Form

hi all
Is it Possible to have Multiple Database Connection With a Single Form
Block a : Retriving data from a database Service a/Schema A.
Block b : Retriving data from a Remote Database Service b / Schema B.
If yes how to do this.

Sure you can access a database this way,
but can you base a block on this database connect? No you can't.

Multiple physical connections on a single repository

Hi,
I have customers who have multiple databases, one for every location. This Databases are identical. So I want to create a single repository and the users from location 1 to see only his data and the users from location 2 to see only his data. Can anybody give me some instructions or documentation how to create the "Business Model and maping"
Thank you
Best regards
Nicolae Ancuta

Hi,
You can try the below mentioned approach.
1> You can create diffrent connection pools for diffrent sites and import the data to the physical layer.
2>DO the corresponding physical joins.
3>Drag and drop the diffrent subject areas formed in the physical layer to the BMM layer. This way you will have diffrent subject areas in the BMM layer as well.
4> You have to proceed the same way to create the complex joins in each of the subject areas.
5> Now you can create diffrent groups for the diffrent sites through
Manage---->Security------> Select Groups--------> Create new group
6> Now right click on the groups you have created and go to the properties.
7> In the General Tab select add and add the corresponding subject area which belong to the region.
8> Check the box next to the read permission.
9> This way you can add the subject areas to the corresponding groups.
This will help you setup your intended results.

Multiple database members in a single Grid Row

Hi All,
I have created an FR report (9.3x) and getting the below error while trying to run the report via Web Preview.
5217: Error Processing Results;hasPovDims=1;povXML=<?xml version="1.0"?><datasources><datasource name="FIN QA" dsid="-117fcde3_132fd17f2f6_-771b" allowEdit="1"><dim name="Versions" dimIndex="0" dsName="FIN QA" keyDimName="Versions" memberName="Versions" displayName="Versions: Versions"/><dim name="Scenarios" dimIndex="4" dsName="FIN QA" keyDimName="Scenarios" memberName="Scenarios" displayName="Scenarios: Scenarios"/><dim name="Components" dimIndex="5" dsName="FIN QA" keyDimName="Components" memberName="Components" displayName="Components: Components"/><dim name="Customers" dimIndex="6" dsName="FIN QA" keyDimName="Customers" memberName="Customers" displayName="Customers: Customers"/><dim name="Assets" dimIndex="7" dsName="FIN QA" keyDimName="Assets" memberName="Assets" displayName="Assets: Assets"/></datasource><datasource name="FINDEF QA" dsid="-607fb334_128b79d246e_-7d0a" allowEdit="1"><dim name="Time Periods" dimIndex="1" dsName="FINDEF QA" keyDimName="Time Periods" memberName="Time Periods" displayName="Time Periods: Time Periods"/><dim name="Scenario" dimIndex="3" dsName="FINDEF QA" keyDimName="Scenario" memberName="SC_Actual" displayName="Scenario: SC_Actual"/><dim name="Versions" dimIndex="4" dsName="FINDEF QA" keyDimName="Versions" memberName="VR_Input_Version" displayName="Versions: VR_Input_Version"/><dim name="Customers_Region" dimIndex="6" dsName="FINDEF QA" keyDimName="Customers_Region" memberName="CU_NA" displayName="Customers_Region: CU_NA"/><dim name="Assets" dimIndex="7" dsName="FINDEF QA" keyDimName="Assets" memberName="Assets_NA" displayName="Assets: Assets_NA"/></datasource></datasources>
In my report I have selected 2 rows where I have selected @descendants of ccounts from one database which is FIN QA and in the second row I have selected @children of Accounts from another database which is FINDEF QA. I am using only ONE GRID here.
Is it not possibe to run a FR report by select members from multiple databases in a single grid??
Please have your valuable inputs.

Yes it possible to retrive data from multiple database using single grid.
Also there are few limitations namely:
Database connections must be of the same type (for example, both must be Essbase database connections or both must be Financial Management database connections).
Mismatched number of dimensions in the database connections may cause retrieval errors.

How to get active monitor-Multiple monitors connected to a single machine.

Hi,
How to get the id of active graphic device, in case of multiple graphic devices connected to a single machine(Multi-headed display/ multi headed nodes) using Swing.
Prashanth.

Ah, youre actually asking different things.
In your topic title, you say youre running separate instances
In your body text, you say you are under different user/schema
So tell me, do you have more than one database or not? How many entries in your TNS file?
I would say, for "multiple database instances"
SELECT
a.id, b.id
FROM
tableA a
INNER JOIN
tableB@OTHER_DATABASE_LINK_NAME b <--NOTE!
USING(id)And of course you will have to look up CREATE PUBLIC DATABASE LINK sql..

Creating Multiple LibrarySession (Connection Pool), Using single LibraryService

Hello,
I am trying to create multiple LibrarySession with a single LibraryService, so that each user can pick a new session from a pool and release LibrarySession back to the pool, when the user task is been completed.
Question.
1. Is it possible to create LibrarySession Pool ?
2. If yes, Can any one suggest, whether there will be any improvement in the performance of the application by doing so, or Oracle IFS internally handles the connection pool mechanism for LibrarySession.
3. Does Oracle IFS handle LibrarySession pool internally.
If there is any code, which does similar action, please do forward.
Best Regards
Sujeem Haries

Sujeem, we do not pool LibrarySession instances for you. You may see a performance improvement if you maintain a LibrarySession pool, depending on the application. See the following post for more info:
Oracle Security & PAM
Please note that although LibrarySession instances are not pooled for you, the underlying database connections are pooled.

Multiple Database access in a single transaction

Hello All,
I have read in a book which states that "according to J2ee Specification,a single transaction(an EJB method for example) may not be provided access to multiple JDBC resource providers.."
Does it mean that i cannot access multiple databases from different vendors in a single EJB transaction??
Any help is very much appreciated
Thanks

Hello Sebastien,
Thanks for your response!!!
Let me make it bit more clear.In deploymewnt descriptor,we define jndi name for any resource and do a lookup on that resource from the code.
Let us consider that resource as JDBC data source for our discussion.usually you define any jdbc data source under a JDBC resource provider.
So my question is,in a single transaction can you access multiple data sources defines under multiple JDBC resource providers.
Ex:A datasource "x "defined under resource provider "A"[say DB2 jbdc provider] and a datasource "y" defined under respurce provider "B"[say mysql jdbc provider].
Thanks

Multiple Database Connections

Trying to develop a functionality wherein we can view data of a remote database (not the database instance where APEX is installed) using the Report.
As APEX doesnot support multiple database instance access from a single workspace/applciation.. any workarounds .. I'v used dblinks previously.. but was on a lookout for a more roboust solution..Dont find db links a reliable opiton.

Hi,
how about delving into the wonderful world of Web Services and XML?
APEX is quite powerful in that realm.
Of course WS adds a little overhead to communication and is a bit slower than a database link, but there are lots of benefits on the other hand. In my opinion it's the perfect option if you plan on loosely coupling your applications (not only APEX - ask the Java folks :-)
It always depends on what your expectations are concerning "Quality of Service". A typical APEX page wouldn't load like a million of rows and therefore Web Services might be the right way.

Multiple Database Connectivity

How do we establish connectivity to multiple databases from within one Java Application. And how do we so without any File DSN? We are developing an application which requires dynamic changing of databases located at remote locations. Please help.

you can use a properties file to load the DB details on runtime based on the criteria.
Just put your DB details in a TEXT file and store it as .properties file. You can read it using any input methods from java and pass the parameters to your connection.
Hope this helps.Cheers,

Need to get data from multiple database instances in a single query

Hi,
I need a small favour from you guys. The prob is as follows:
I need to get name, row_id from table A from schema 1 and gbu_name, name from table B from schema 2 where a.name = b.name. I wrote the query in the following manner:
SELECT a.name, a.row_id, b.gbu_name
FROM Schema1.A as a, Schema2.B as b
Where a.name = b.name
But this query is not working and the error is like " The table does not exists".
Please update me how to avoid the error and get the right sort of result.
Thanks & Regards,
Debabrata

Multiple submit button on a single form

hi all,
My current system have 1 submit button with single form. This submit button will call file_content.upload.
htp.p('function on_submit() {');
htp.p('     ...the rest of my code here..');
htp.p('     document.forms[0].submit();');
htp.p('     return true;');
htp.p('}');
htp.p('<form enctype="multipart/form-data" method="post" action="file_content.upload">');
htp.p('     ...the rest of my code here..');
htp.p('<input type="button" id="btn_Submit" value="Submit" onclick="on_submit()"></form>');
My question is, i want to enhance this by adding additional 1 submit button with value "Save". But this new "Save" button will call/trigger different file. This new button will call file_content.update. How to accomplish this and how to differentiate these 2 button?
htp.p('<input type="button" id="btn_Submit" value="Submit" onclick="on_submit()">
<input type="button" id="btn_Save" value="Save"></form>');
Appreciate any help from you guys. Thanks

Parallel database connections and single query between databases

Hi, I am looking to execute this SQL query between 2 different databases to update a local database based on data selected from a remote one.
e.g.:
- Local database name: db1
- local database schema: dbo
- local database table1
- remote database name: db2
- remote database schema: dbo
- Remote database table: table2
- Query: "SELECT * FROM db2.dbo.table2 WHERE NOT EXISTS(SELECT * FROM db1.dbo.table1)" <- This gets e the record set i would need to insert, and I already have a vi to do that kinda thing.
How do I go about this?
Thanks,
Mohamed

Mohamed,
There is a VI in the Database Connectivity Toolkit that allows you to execute SQL queries: DB Tools Execute Query.

Is this what you are looking for?

Multiple Database Connections in ADF?

Hi,
For school we have a project. The goal of this project is to create an application that can generate business rules in PL/SQL. The application must be build using JDeveloper 11g 11.1.1.3.0 with ADF and must be a swing application. We didn't have very much experience with ADF swing.
Within this swing application you must enter the data which is needed to connect to the specific database. When you connect, it will get all the metadata of the connecting database/schema, because we can create a user friendly UI which shows the tables and when saving this it must be stored into another database (repository). So we only need the first connection to get all the data, then the connection could be broken. The second connection is more important, because we nee to save the data to the repository.
Both databases are Oracle databases.
I have been looking how we can achieve this, but with no result (I saw a solution like this: How do I use dynamic credentials in a J-Client App? but don't now how to implement it.)
Thanks in advance

The ADF model layer usually takes care of handling instances of you Application Modules, and here, you are doing it manually. This brings some risk, and be careful to release the Application Module after use.

How to handle multiple database tables in a single UIX page?

Hi,
I am new to UIX & BC4J. I have to handle data from four different tables in the database. The scenario is as follows:
The tables are
1. user
fields are: userid number, name varchar2
2. business
fields are: businessId number, name varchar2
3. service
fields are: serviceId number, serviceName varchar2
4. userBusiness
userid,businessid (both are foreign keys) & form complex primary keys.
and userid,businessid, serviceId are primary keys.
Now my problem is: to create a webpage where
1. The userid is available in the httpSession Variable as string.
2. according to the userId stored in the session variable I have to retrieve the business names and show them in a choice i.e., pull down box.
3. I have to show the services provided by the business for the business name selected in the combo box.
Could anyone Please help me solve this problem? Could you please give me hints? I have truncated the other fields in the tables.
Thanking you,
Velpandian .S

At the moment, you can't do it declaratively. You have to do it in an event handler. Assuming you have the userid setup as a query parameter in the view object, something like this should get you started:
public EventResult handleEvent(
BajaContext context, Page page, PageEvent event) throws Throwable
HttpSession session = context.getServletRequest().getSession(true);
ViewObject view = ServletBindingUtils.getViewObject(context);
String userid = session.getAttribute("userid");
view.setWhereClauseParam(0, userid);
view.executeQuery();

Using Java within a stored proc to access multiple database connections

Hi List;
We have an environment where we have needs to provide cross database visibility between Oracle, Sql Server and PostgreSQL. So we need the capability for Oracle to query PostgreSQL and Sql Server tables, PostgreSQL must be able to query Oracle and Sql Server tables and Sql Server must be able to query Oracle and PostgreSQL tables.
I'm thinking that we can implement stored procs which are either written in java or call a java process . The java code in turn should be able to connect to any DBMS desired via JDBC query the tables in question and return the result set to the calling database.
Any thoughts on how feasable this is would be appreciated. Does this seem like a solid solution? Any initial concerns or red flags? what about performance via JDBC?
Thanks in advance for your help.

John,
from your description I understand that you essentially program the VO yourself. So I suggest that you read chapter 35.9 of the 'Fusion Developer’s Guide for Oracle Application Development Framework' (I guess you know where to find it). Since you still call the actual SQL not all of the chapter apply, but you get the idea how it works.
And yes you analyzed the behavior correct. executeQueryForCollection() is allways called bevore getQueryHitCount().
