Migrating access 2000 to oracle 9i

Please I have two questions
i) I am trying to migrate an access 2000 database to Oracle 9i and I am at the point where it asks me for the ODBC data source please where do I get this information.
ii) ALso please can anyone tell me what are the 5 layers involved in migrating an access database to oracle

Arun,
Can you provide a reproducible test case so that we can confirm the behavior here and log a bug? More detail can be found in the log/Error.log in case there is a java exception that is being thrown.

  • Migrate Access DB to Oracle

    Hello,
    I downloaded migration tool and did the migration of Access 2000 to Oracle.It worked great..
    But, I am not seeing the converted database in Oracle.Not sure, if I am missing anything.
    I have the converted XML file.
    If anybody throw some light on this, I would really appreciate it.
    Thanks

    you need to use that XML file in the Oracle Migration Workbench and go thru te process of loading the XML, transforming it to the Oracle Model and creating your Oracle Schema in the database. This is all documented in a step by step method in the user's guide

  • TNS listener problem when migrating access app to oracle

    I am migrating an access 2000 DB and application to oracle 8i. I have done this successfully on my test machine many times. I am working on the customers machine, and the problem is when I go to migrate the access application, it will not connect to oracle b/c of the TNS listener. The workbench tool ask for a username, pwd, and ODBC driver, but there is no place to put the oracle service name. I ran into this problem at home and I appended the service name onto the password with the '@' symbol, which works for oracle anyway. Like this, 'pwd@sname'. It worked at home, but I keep getting an error here that tns could not resolve service name. When migrating the data, there was a field to put the service name in, but not for migrating the application. I have tried variations in the ODBC driver also, but with no luck. Any other ideas?

    Hello,
    Is it possible that odbc driver is nor properly installed? If so you may have to re-instlal the odbc driver. If not try out the following steps:
    * Go to DataSources [On win2k: start -> settings ->control panel ->Adminsitrative tools -> Data Sources (ODBC)]
    * Click Add for the user DSN [say "testDSN"], and select oracle driver here [check if you have oracle 8 driver, if not you may want to install one]
    * In the "Oracle ODBC Driver Configuration" window, give you your oracle databse connection details, click the "Test Connection button", it will ask for username and password, give system's username and password
    * Use this DSN [testDSN] name in the migration work bench
    Thank you and kind regards,

  • MS Access 2000 and Oracle 8

    Hello,
    I need to provide access to a Oracle (v 8) table via MS Access 2000. I am doing so via Link Tables in MS Access.
    But I am not able to see the new tables that I created, in the list of tables available for linking from the Oracle schema, in Access.
    How can I rectify this?
    Thank you.

    I think you'd need to contact Oracle support to get access to older versions of the driver.
    Since 8.0.5 isn't supported any longer, however, is it possible for you to update your Oracle client to one of the supported releases-- 8.1.7 or 9i?

  • Migration: Access 2003 to Oracle SQL

    Dear All
    I would like to perform a migration from Access 2003, to Oracle 10g. I am using SQL Developer for the task, and have reached the point of capturing the XML file that I exported from Access. I need to create a migration repository on the target database, and this is causing problems as I do not have all the necessary privileges.
    In the process, I have been advised that migrations from Access to Oracle are not easy to achieve, and in fact require careful planning before execution. My objective is not really to transfer the data stored within the database file. I only really want to convert Access logic into Oracle SQL code. I was wondering if anyone could advise on the typical odds of success in achieving this task.
    I migrated the same Access database to MS SQL Server some time ago and the process seemed to go smoothly. Would it be reasonable then to migrate from MS SQL to Oracle SQL if this is easier?
    Any feedback would be very much appreciated.
    Thank you.
    M

    Thanks for your response.
    I am not familiar with the intricacies of the process, I'm just following the instructions set out in the Oracle Migrating 3rd Party Databases white paper.
    In this document, a process is set out consisting of steps that export an Access database, and then capture it to an Oracle user area with appropriate privileges. The process is achieved through Oracle SQL Developer.
    I'd be very grateful if you could expand on your answer if there is a better way of translating Access queries into Oracle SQL. I am aware that an Access front-end is capable of connecting with an Oracle database to execute queries, however, there are considerable limitations in the use of Access that I would like to avoid - hence the migration.

  • Best way to migrate Access data into Oracle 10g?

    what's the best and easiest way to migrate MS Access database into Oracle10g?
    Thanks

    you can check out this thread ms access db to oracle 10g
    <p>also as neil mentioned you need an ODBC to established a database connection between ms access and oracle. be sure that the tables are existing in oracle so you move the data from ms access to oracle tables.</p>

  • OS migration Access(Win) to Oracle(Linux)

    I have migrated a Access DB to Oracle 9.2, both running
    on Windows on the same computer. Now I want to do the same thing but to a Oracle DB running on Linux.
    Is this possible???
    What would the difference be?
    I´d appreciate tips in this matter.
    /Dag

    There is absolutely no difference. Once you have the odbc connection setup to the oracle db, it doesn't matter where it is, on windows or linux.....

  • Migrating Access DB to Oracle Hosted APEX environment

    I was wondering if there was a way to migrate an Access DB to the Oracle Hosted APEX environment using the Oracle Migration Workbench? You have to specify the location of the DB and schema and I don't know this information since the DB location is on the Oracle Hosted site. I would like to evaluate the migration functionality of the APEX tool without having to download it locally along with Oracle 10G. Is there a way to do this using the Hosted website?
    Thanks!

    The quick answer to this is no.
    However, there are some services (http://www.appshosting.com) which do offer that type of access at no charge.
    Thanks,

  • Two errors attempting to migrate access 2000

    Hello,
    I am using omwb 10.1.0.4.0 - as I am on NT I think that is the last version I can use. I don't think I can run SQL Developer (Don't ask why I am on NT)
    When I select the mdb file to migrate in the access-exporter I get error #5 - Invalid procedure call or argument. And when I attempt to export schema I get error #35021.
    So far I have removed any faulty references, have compressesed the database and performed a analysis on the tables. Checked the ODBC driver version (4.06.6205.00) and tried again..still the same result.
    But I am able to dump the table data out. I am able to use the older version 9.2 of the omwb..this does at least get me the schema. This I used to make my developer oracle database.
    I will need to run sql*loader on the data as this initial process is just getting the development system on Oracle working. I will need to load live data to it soon. Anyway omwb will make me the SQL*Loader control file?

    Thanks,
    The link didn't work, but with a bit of searching I found the post. I have downloaded SQL Developer and after modifying the .bat file to run the proper jre it works! I had a bit of a scare as I managed to remove some controls accidentally as I was clearing space (silly Windows)...all is well again..whew!
    I am not able to download the migration workbench update however. the urls don't seem to work. I am behind a firewall and have provided the proxy server. I tried the url in the error message http://download-uk.oracle.com/otn/java/sqldeveloper/oracle.sqldeveloper.migration.translation.gui.28.54.zip
    in my browser directly but the destination could not be found.
    Is there another way to update SQL Developer?
    <edit>I tried it again and guess what? it worked! Obviously around lunch time the LAN frees up a bit
    Will let you know how it goes</edit>
    In the meantime I'm scripting my own .ctl file creater and scripting the .csv exports from Access. I've tried sql*loader and works just fine on the small files I've tried.

  • Migration: sqlserver 2000 to oracle - delete cascade [resolved - tank you]

    hi
    no problems on migration... but...
    in the new oracle database, all foreign keys have the "cascade delete" as default...
    but i don't want this default (a stupid human error may be ruinous...)
    can somebody explain me how change this default in a "exception thrown"?
    maybe with an authomatic sql order????
    tank you a lot...

    Hi Giovanni,
    Tools> Options> General
    Create Foreign Keys with "ON DELETE CASCADE" option
    Just untick the box and remap from the source to the oracle model.
    Hope this helps

  • Migration Access to Oracle with GUID fields

  • Altering database during migration from MS Access 2000

    Hi to all Oracle forum members.
    I want to migrate a MS Access 2000 database to Oracle 9i release 2. I want to know how can I alter the database design during the migration progress. My plan is to split an existing table to more and re-arrange the data and maybe introduce some new tables as well. These changes cane be made using the Migration Workbench or after migrating to Oracle? What is the most efficient way to do that and how can I accomplish these changes?
    Thanks in advance...
