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,

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.

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?
IÂ´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.....

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,

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.

Hosted APEX Site down??

Folks,
I have been trying to access the Oracle Hosted APEX site all morning and it seems to be down, can anyone confirm this?? I was doing a small demo for someone on using the mail merge code back from HTML-DB 1.6 (downloaded off the HTML-DB Studio)..
Thank you,

Hi Tony,
It's been down all afternoon (London time) and seems to have crashed just as I was in the middle of setting up a demo page as well :(
I've just tried again, and it's still on its tea break

Migrate From MS Access 2003 to Oracle using Oracle SQL Developer 3.0

Hello All,
I am trying to migrate Access DB .mdb using the Oracle SQL Dev 3.0 Data Migration Wizard, everything go very nice and smooth until the Capture Step, for sure am using the online mode, in the Capture Step the list of available databases is empty and a Msg Box saying that the DB list should have at leats one database selected, so I don't know what's that mean or how to fix this.
in my .mdb file I have four tables and I can copy the data to Oracle using the Right click and copy to Oracle Function, but it really takes much time.
Any help would be really appreciated and thanks in advance.
yours,
Hussein

Just to clarify:
You have created the migration repository and start the migration using Tools => Migration => Migrate
- now you've selected the repositiry
- specified a project
- selected the source database
=> you've choosen the ONLINE Mode
==>> and now you don't see your MS Access database in the "Connection" List
Is this correct?
If the steps you're doing match the steps I've posted above, then please be aware for MS Access migrations you need to choose the OFFLINE method. The MS Access source database information is collected by the MS Access Exporter available from Tools => Migration => MS Access Exporter
Once you've created the XML/OCP file you specify this newly created file during the OFFLINE migration mode.
If your steps differ from mine, please post yours more detailed.
Thx.

Access 2003 to Oracle Migration Queries

Hi Experts,
I have taken up a project to migrate Access 2003 application to Oracle 9i.The Forms and Reports will continue to run in Access 2003 with Oracle 9i database. I decide to use Oracle Migration workbench for the migration purpose.What I think is the back-end i.e. database and queries will be automatically migrated to Oracle 9i but I'm not sure about the front end application.
Do I need to change front end application to point to database in Oracle 9i or OMW will do that itself.I am also confused with lots of queries that reside in current Access database. I presume these queries will be converted to Oracle procedures/views without any manual intervention but will the front-end application also be modified automatically to point to those stored procedures/views. Otherwise an extensive code change will be required which may result in huge cost.
Currently the Access application is not using any ODBC DSN as it gets connected to the database automatically. Should the database connection be changed to use DSN prior to Migration?
One more thing, the application is using single-level linked table. Will the linked table get automatically converted and connected or I need to do anything?
Could anyone help me in this issue by giving some ideas so I can manage the job efficiently and make proper planning before plunging into the real work.
Thanks & Regards
S C

The Migration Workbench will modify the Access mdb file as part of the migration if you request it, to create the necessary link tables to oracle, it will use an ODBC DSN to do this. This is explained in our documentation. This should be transparent.
However for complex application, you often have a tuning exercise, to ensure that the jet engine does the "right" thing, and there changes are required, e.g. a two way join, you would want that to happen on the server and not done on the client. This would be same tuning exercise, if the back end was SQL Server.
In the latest release of the Access plugin, we did a better job migrating queries to views, but you need to plug this into your code.
Yes, the exporter should extract the information about the linked table, assuming the link is valid at the time of extraction.

Migrating Access to Oracle

Hi Guys,
I am new to Oracle and hope you guys would be able to help me out. I need to migrate almost 20 access databases to oracle. I searched some tools for this and finally found out that workbench does almost everything I am looking for including
1. Migrate the data from access
2. Remove access tables and create links to access forms and queries
Other tools do not change the tables to oracle link table after migration. Anyhow, there are some issues I need to discuss with you guys.
1. I already have username created in Oracle. How can I migrate tables to this username with creating another one. I need to migrate all 20 databases to the existing username in Oracle?
2. How can I proceed without assigning the user DBA priviliges? The existing user and the user created by workbench 'omwb_emulation' require DBA priviliges to complete the migration process.
I hope I explained what I am looking for. Any help would be appreciated.
Thanks.

Hi,
I hope I can help to clarify some issues for you.
a) You state that you have 20 access databases that you wish to migrate. Are these 20 databases unique, or are there some duplicates in there which are not required/used? If there are duplicates, I would recommend removing them from the scope of your migration project.
b) It is feasible to proceed through the migration process without assigning a user DBA privileges. Specific roles and privileges are required by a user in order to proceed. Please refer to Chapter 1, Introduction of the Workbench User's Guide, section "Accessing the Destination Database", for the full list of required roles and privileges. I would recommend creating a user with these specified privileges, e.g user "omwb_user" and then use that user which using the workbench.
c) You mention that you already have a username in Oracle that you wish to migrate the tables to. During the migration process the workbench creates a schema, using the name of the MDB being migrated e.g. Northwind. The database is then migrated to that user. If, for example, your existing username is called "test_user" and you wish to migrate all 20 MDB files to that user, you would need to do the following:
1. Drop "test_user" from the database. The workbench will then create this user as it proceeds through the migration process.
2. Rename each MDB file to "test_user.mdb". As I mention above, the access database information is migrated to a schema name matching the database name. If you want all 20 MDB files to go to the one schema, then they must be named the same. You will have to place in MDB in a separate directory so that they can all be named the same e.g \dir1\test_user.mdb, \dir2\test_user.mdb, etc..
3. From the \msaccess_exporter folder under your omwb workbench installation, execute the exporter tool that corresponds to the version of the MDB files you are attempting to migrate e.g for MS Access '97 databases, use the omwb97.mde file.
4. In the exporter tool, select all 20 MDB files, supplying "Alternative Name"s where required by the tool. This tool will generate an XML file for each of the selected MDB files.
5. Launch the workbench, logging is as the user with the required privileges that is referred to in point b) above, and load up the 20 XML files generated in step 4.
6. Proceed through the Capture and Migration wizards, to migrate all 20 access databases to the one "test_user" schema.
I hope this helps to answer your questions.
Regards,
Hilary

Unable to access Oracle XE Apex Interface

Hello,
I've recently installed Oracle XE on Ubuntu (package oracle-xe-universal_10.2.0.1-1.1_i386.deb), however I am unable to access the web interface for Apex. If I use Firefox or Opera, it cannot recognize the file it's trying to access, but reports it as an application/octet-stream file and asks me how to open it or to save it to disk. If I use IE7, it simply displays a few unknown characters (boxes).
I had the entirety of Oracle XE installed and working prior to rebuilding the server, which is when this problem began happening, but I shouldn't have changed anything to cause a problem like this.
If anyone can shed some light on this, I would greatly appreciate it, since I've been unsuccessful at finding anything out about this problem.
Thanks,
Jeff

This is a bit old but I've faced the issue and found a (temporary?) solution.
The problem is caused by a syntax error of the generated HTML on the Change Password page. The APEX page generation code somehow truncated a closing '>' in a tag. By adding a few space, this page generated correctly. However, it seems very likely that the problem will also occur for other pages.
In file builder/f4350.sql, line 5668, change
p_plug_source=> s,
to
p_plug_source=> s || ' ',
Then reload the page... I used 'sys as sysdba' and not sure this is the best option. Anyway the page showed afterwards.

Oracle Hosted instance of APEX having issues today?

Just tried logging into to download some stuff and I am finding the Oracle hosted instance of APEX is having issues.. Anyone else notice this or dealing with this today?
Thank you,

Hi Tony,
It appears to be Web server related. I can't even get to http://apex.oracle.com (a static file). I just filed a P1 ticket for our IT organization to take a look and fix it.
Thanks for reporting this.
