This section provides an overview of the process of migrating applications from Microsoft Access to Oracle Application Express.
This section contains the following topics:
Oracle Application Express Application Migration Workshop (Application Migration) enables you to migrate a Microsoft Access application and generate an Oracle Application Express application from the retrieved objects.
This migration begins with exporting your Microsoft Access metadata, using the Exporter tool together with Oracle SQL Developer Migration Workbench. After that initial step, you use Application Migration to review the retrieved objects and resolve any issues regarding invalid objects. As the final step, you have the option of generating either an application based on valid forms and reports or a maintenance application based on valid tables and views.
Once the application is generated, you can take advantage of all the functionality in Oracle Application Express to further develop and publish the migrated application.
Forum for Application Migration
In addition to Oracle support, you can post questions on the Microsoft Access Migration to Oracle Application Express:
Before you begin the migration process, verify that your system meets these requirements:
Oracle Application Express version 3.0 or later
You must install Oracle Application Express 3.0 or later. You use the Application Migration feature within Oracle Application Express to download the Exporter tool as well as to migrate Microsoft Access forms and reports to Oracle Application Express.
Oracle SQL Developer 1.2 or later (available in English only)
You must install Oracle SQL Developer version 1.2.0 or later. You use the Migration Workbench extension to migrate the Microsoft Access schema and data to Oracle.
Exporter tool version 10.2.0.2.5 or later (available in English only)
You can install the Exporter tool using the Download Exporter link within Oracle Application Express. For instructions, see "Step 1: Export Microsoft Access Metadata".
If you are using Oracle SQL Developer version 1.2.0 or later, you can access the Exporter tool directly from the Migration menu.
Microsoft Access
Your local system must have Microsoft Access installed, and it must be installed where the Exporter tool and .mdb file reside.
Microsoft Data Access Components (MDAC)
Your local system should have the latest version of Microsoft Data Access Components (MDAC) installed. You can download the latest version from the Microsoft Web site.
Printer
Your local system must have a printer installed so that a report can be opened in design view. This is a requirement for exporting your Reports information from an .mdb file.
Analyze your .mdb file before you export your database. Follow the instructions in the next section.
Analyze Your MDB File in Microsoft Access
Using Microsoft Access, you should analyze your .mdb file before you export your database. Performing these steps will minimize errors in the migration.
In Microsoft Access, analyze the objects in your .mdb file:
From the Microsoft Access menu bar, select Tools, Analyze, and then Documenter.
Select the All Object Types tab, and then click the Select All button to select all the objects within the application for analysis.
Remove or resolve any erroneous objects reported by the Documenter.
Ensure the application contains no missing references:
In Microsoft Access, launch the design IDE (press Alt+F11 keys).
From the menu bar, select Tools and then References.
Remove or resolve any missing references.
Ensure the application compiles successfully:
From the menu bar in the IDE view, select Debug and then Compile.
Resolve any reported errors.
Perform a compact and repair on the database:
From the menu bar in Microsoft Access, select Tools, Database Utilities, and then Compact and Repair Database.
Ensure that all linked tables are valid links:
From the menu bar in Microsoft Access, select Tools, Database Utilities, and then Linked Table Manager.
Verify that all links are up-to-date and pointing to an existing .mdb file that is not read-only.
