This topic contains the environment changes made by the ODAC installer. If you are having problems with using ODAC or compiling ODAC-based products, check this list to make sure that your system is properly configured.

Compiled versions of ODAC are installed automatically by the ODAC Installer for all supported IDEs except for Lazarus. Versions of ODAC with Source Code must be installed manually. Installation of ODAC from sources is described in the supplied ReadmeSrc.html file.

Before installing ODAC ...

Please read our Compatibility page and make sure that your system satisfies the requirements.

Two versions of ODAC cannot be simultaneously installed for the same IDE, and, since the Devart Data Access Components products have some shared bpl files, newer versions of ODAC may be incompatible with older versions of MyDAC, IBDAC, and SDAC.

So before installing a new version of ODAC, uninstall any previous version of ODAC you may have, and check if your new install is compatible with other Devart Data Access Components products you have installed. For  more information please see Using several products in one IDE. If you run into problems or have any compatibility questions, please email [email protected]

Note: You can avoid performing ODAC uninstallation manually when upgrading to a new version by directing the ODAC installation program to overwrite previous versions. To do this, execute the installation program from the command line with a /force parameter (Start | Run and type odacXX.exe /force, specifying the full path to the appropriate version of the installation program).

Environment Changes

To compile ODAC-based applications, your environment must be configured to have access to the ODAC libraries. Environment changes are IDE-dependent.

For all instructions, replace %ODAC% with the path to your ODAC installation directory

The ODAC installation program only copies ODAC files. You need to install ODAC packages to Lazarus IDE manually. Open %ODAC%\Source\Lazarus1\dclodac10.lpk (for Trial version %ODAC%\Packages\dclodac10.lpk) file in Lazarus and press the Install button. After that Lazarus IDE will be rebuilded with ODAC packages.

Do not press the Compile button for the package. Compiling will fail because there are no ODAC sources.

To check that your environment has been properly configured, try to compile one of the demo projects included with ODAC. The ODAC demo projects are located in %ODAC%/Demos.

Installation of Additional Components and Add-ins


If you use Delphi Enterprise Edition, Delphi Architect Edition, or C++Builder Enterprise Edition, you can install the TOraProvider component by compiling and installing the oraprovXX.bpk package.


DBMonitor is a an easy-to-use tool to provide visual monitoring of your database applications. It is provided as an alternative to Borland SQL Monitor which is also supported by ODAC.
