Integrate 300 MS Access Databases using ODI

Hi All,
I am trying to integrate data between 300 similar MS Access databases using ODI. All the source databases have exactly the same data structures. I have done a POC for 3 databases by creating interfaces and could integrate the data between them successfully.
Now that the project is approved ; Going forward I need to integrate data from 297 MS Access databases, so I need to run the same set of Interfaces on 297 source MS Access Databases with Target DB being the same.
This integartion work could be labourious as I need to copy 7 interfaces on 297 databases - IS THERE ANY EASY SOLUTION FOR THIS PROBLEM.
Some one suggested me to use Dynamic Variables in the TOPOLOGY to access all the MS Access databases - BUT NOT SURE IF THAT WORKS.
APPRECIATE your suggestions.
Thanks & Regards
Kay

The issue you face here is that the Access database is connected to through the JDBC-ODBC bridge to the Access ODBC database driver. You will need to have a separate DSN defined for each of the access databases, if you want to address each individually.
An alternative approach is to have one DSN set up, one entry in ODI's topology, one interface etc, and each file you wish to use, you rename to a given name first. Thus, when ODI tries to access the database, the ODBC driver finds the then current file. Note that ODI keeps the database connection for the duration of a SESSION, so if you wanted to process all 300 files sequentially, then you would need to run separate sessions for each of the file executions.
I think this will give you the solution you require without resorting to variables.

How do I open a pdf stored in a Microsoft Access database using Visual Basic studios 2012

Currently I am unable to find a valid method of being able to open a pdf stored in a Microsoft Access database using Visual Basic studios 2012. I've tried displaying the entire database on a form, but when I do this all the other columns show up with
the correct data besides the one containing the pdf's, it just displays <binary data> in each row down the column. I also tried another method with which you use the database as a dataset and can drag and drop the rows and columns into the form, which
again works for all the other columns besides the one containing the pdf's but this time I'm unable to interact with the column at all.
Not too sure if this is in the correct place, but any answers or help would be appreciated. Cheers.

Alex,
This forum is dedicated to Project and Project Server. You might get better response, if you post to a Visual Basic forum. Here are couple I could find.

Setting System DSN for MS Access Database using Java Code

How to set the system DSN for Access database using Java Code at runtime....???
Replies are deeply appreciated...

I found a 3rd Party MS Access JDBC Driver from a Google search. I downloaded and tried the free trial version. It worked fine but we opted not to purchase the full version and went a different route. If you don't find it, let me know and I'll see if I can track down the name of the product we tested.

Integrate source db with target EBS database using ODI

Hi
We have a requirement to integrate our legacy systems to Oracle E-business suite 12.1.1 database 10g. We have several MS-SQL and oracle databases that has to be integrate with our Oracle EBS database. Oracle says to have separate schema for Master and Work repository, and also create a new schema when connecting to the data store and use the same schema as a WORK SCHEMA when creating a physical schema. My question is:
1) What are all the privileges to be assigned to the new schema used as a WORK SCHEMA? Oracle EBS holds many FND schemas and APPS uses the synonyms of all the tables. So what oracle recommends when using EBS with ODI?
2) Do we need to create a separate work schema for each and every SOURCE Database as well?
3) We are not using separate oracle database for ODI we will be creating schemas in PROD to hold ODI data. Our management wants the the odi schema to hold the staging data. Can we use the the same Work schema mentioned in the first point as a staging area as well?
Thank you
Regards
Shahrukh Yasin

Hi Shahrukh ,
There are two ways.(1st one is recommended)
1.You can make source schema in one database and target schema, work schema in another database.
For source schema only read only access privilege.
You must have complete ownership in work schema and target schema(Minimum insert,update,delete).
Here you have to always create one work schema in every target database
2.if all schema present in 3 different database,you also need above criteria.
But here you don't have to create work schema always.its fixed.
This process takes much time for transformation and not an efficient way.

I want to access a remote MS Access database from oracle stored procedures.
Does anyone know how i can load the RmiJdbc driver using the loadjava command or with any other way.
Because when i try to load RmiJdbc.zip using the loadjava command I am getting the error:
ORA-29533:attempt to overwrite class or resource string while defining or compiling scott.TestClient
this error is occured for multiple files...
I don't know how to delete this classes.
Because this error occured and the first time i tried to load Rmijdbc driver.
and when i use the dropjava command to drop it,and then load it again the same error occures.
Can anyone help me how to load this driver?
Please answer because i need it as soon as possible.

Creating a new access database using JDBC

Hi Forum,
I have a problem in hand. Let me describe the problem:
I want to create an "access database" from java at runtime. "Access database" is file based, so for a database named test, it will have a file test.mdb.
Now, everything's sweet and wonderful, if somebody creates an "empty access database" at the client machine and i then connect to it and create the tables i require.
But the issue is i want to create the database at runtime (the database name and tables are determined at runtime).
Using the JDBC:ODBC bridge driver , i am able to connect to an existing database, but any "create database" statements are not supported.
A last ditch solution would be that i create an empty database using access and copy the file contents in the SQL server database as a a blob object. Then when i want to create a new access database at runtime, i create a file in a particular folder , with an .mdb
extension, copy the file contents from the SQL server (i also have an SQL server connection) BLOB object, and then try to connect to the
.mdb file.
But this approach seems a "quick hack" and can have problems (which i can't see as of now).
Can you suggest a better alternative for the problem.
See the Java Sun forum at this address for a discussion of a similar problem, but sadly with no solution.

I have an applet that was previously connected to Oracle 9i. I am faced with connecting to MS Access temporarily for testing purposes.
I have been unable to successfully code connection in java. I have set up the DSN and can access in SQL Worksheet in JDev.
I saw your question regarding creating an access db, and thought you might be so kind as to help me code the connection to access!!!!
Any help you could provide would be greatly appreciated. I have a huge application to finish with alot of sqlj already completed. Connectivity is not my area of expertise!
Any help you could provide would be greatly appreciated!!!
I am not sure if I have to use bridge? Am I progressing in right direction to migrating to SQL Server if need be?

Remote access database using EM Database Control Console

When I install the Oracle database 10g, it gives me two choices:
1)Using Grid Control for Database Management and
2)Using Database Control for Database Management.
When I select the #2, according to the Guide, I'll be able to manage my database locally. (Assume the database server's IP address is: DB_IP_Address, then I can use: http://DB_IP_Address:5560/em). But wait a minute___
a)What does this "locally" mean? If the Oracle DB is installed in a remote location, and there is no LAN connection to it, can I still access it via the Oracle Enterprise Manager (Database Control Console)? (i.e., via the HTTP protocol)
b)The same question is asked for the iSQL*Plus in regarding to the remote access. I guess the answer to a) above will automatically answer the b) ? (Actually I doubt that I can access remote database using the iSQL*Plus via HTTP protocol).
Thanks
Scott

Hi,
and there is no LAN connection to itWell you'll need some network link in order to connect successfully.
What is meant by locally is that you can only manage databases installed on the local computer.
For example if you installed it on machine "CPTR1", and on another machine "CPTR2", then you can't use http://cptr1:5560/em to manage the databases on "CPTR2. And vice versa.
About iSQL*Plus, in fact, as far as the tns alias is ok from "CPTR1", you can connect to the databases on "CPTR2", "CPTR3", ....

thanxAnd that SQL statement is another reason to use PreparedStatement. I assume bname and sname are input from some form? Well, if that's the case, simply inserting them into SQL by simple String concatenation is just begging for all sorts of problems. What if there is an apostrophe in the entry? Broken Statement. Worse, it's a wide open invitation to an SQL Injection attack.

Uploading images in access database using jsp

Hi, am using jsp with access database and want to upload as in a profile picture for any profile on the site[i mean depending on the user's convenience] ..
I just have a code which helps select the image from the client's machine n gets its address..but then how to use it in a form or something so that it can be submitted and inserted in the database?
Any idea? I d prefer not using servelet.. but if it just cannot be done without servelet then ok can suggest with that too.
Here is the code of Browsing to obtain the picture:
<form name=uploadForm action="uploadpic.jsp" method=post enctype="multipart/form-data" > <input type="file" > <input type="submit" name="submit" /> </form>

bad. Don't put business logic in JSP, and that includes accessing databases.

Don't put business logic in JSP. That's what servlets are for (and EJB).

Accessing database using EJBs in WebDynpro

Im using EJBs to access database...data is getting stored in the database...but i dnt know how to retrieve it...webDynpro is a totally new environment for me..it would be a great help if someone can help me solve my problem...
regards,
Sonal

- start with "import JavaBean model" (importing model)
- put model in Used Models
- bind model with controller (web dynpro components-> double click on <application name>
- bind view with controller (same vindow)
- apply template (table for reading data) in view
and you are redy for start.
Eq
your EJB is MyEJB, and there is some function myFunction() with Vector as return (Vector contains MyEJB objects)
now in controller put (eq in wdDoInit())
MyEJB myObject = new MyEJB()
wdContext.current<NodeName>.bind(myObject.myFunction());
good luck

Access database using Java from HTML webpage

Hi,
I've got to create some online maths tests to be taken by students with their marks being stored in a database.
I've wrote some simple java code which can add/remove and modify entries in a test mySQL database that I made. What I now need to do is be able to add entries to the database from a html page.
The math tests will be java applets with the students having to interact according to questions, press submit and their score will be output. The score will then be entered into the database.
The problem I'm having is that with an Applet their are all sorts of security issues (I'm having problems getting images to load in an Applet) so assume I'll face the same security issues when I try to access a database through an applet.
So, could someone please help get started.
Cheers

MVC - I assume you mean model-view-control and not Marvel vs Capcom :)
If so then does this mean I should completely seperate the user interface (the actual applets that will contain the test), the database (that will store the results) and the link between the two?
is it possible to acheive this using Java, Java Applets, Java Script and the database (in my case mySQL) and could you give me some tips on how best to tackle the problem.
Thanks

Remote access database using Application Server Control Console

When I install the Oracle Application Server 10g, it gives me a web-based tool, i.e., to use the Application Server Control Console to manager/monitor the server.
Now If the Application Server is installed in a remote location, and there is no LAN connection to it, can I still access it via the Application Server Control Console? (i.e., via the HTTP protocol). (I believe that I can only use the Console to manage the AS which is physically located in the same machine).
Thanks
Scott

Hi Scott!
The ASC will allow you only to manage its own installation. So if you have 10 AS instances you will have 10 ASC's to manage it.
If you want to remotely manage your installations you need the Grid Control.
Otherwise you will need a connection to the machine.
I do not understand the issue about the "no LAN connection"? How do you want to access the machine if there is no network connectivity anyway?
