Shared Database Library Support in Iguana

Note: Iguana may not always support the very latest version of the Oracle or MySQL shared libraries, if this is the case you will need to use an earlier (supported) version. This is particularly true if you are not able to use the the latest version of Iguana.

If you need to know which versions of shared libraries are supported by the version of Iguana you are using please contact us at

Iguana uses the following methods to find shared libraries on your system:

  • If your Iguana server is running on Windows, Iguana first searches the registry for any installed shared libraries. If MySQL and Oracle are installed properly, there will be registry entries for their shared libraries. If you are using MySQL 3.23, a registry entry will not be detected.
  • If a shared library is not found using a registry search, Iguana will check the directories contained in the system search path.

Iguana supports the following MySQL shared libraries: 3.23 and greater. You can use Iguana with any MySQL database that can successfully interact with any of these libraries.

When searching for an Oracle library, Iguana uses the default installation specified by Oracle, if one exists. Otherwise, Iguana selects the first supported version it finds. You can use Iguana with any Oracle database that can successfully interact with the selected library.

If you have multiple versions of a MySQL or an Oracle OCI shared library installed on your computer, you can use the Database Settings page to specify the version of the shared library to use. Normally, the version that Iguana detects will be safe to use.

If your Iguana server is using a MySQL shared library or an Oracle OCI shared library, and you change the shared library that Iguana is using, you must restart your Iguana server before you can use it again.
