PL/SQL Web Toolkit

APEX requires version 10.1.2.0.6 or later of the PL/SQL Web Toolkit.

The version of the PL/SQL toolkit doesn't necessarily correlate with the database version you are using. To find out your current version, you can run the following:

select owa_util.get_version from dual;

If your current version is older than the required version, you should install the newer version prior to installing APEX.

The necessary PL/SQL Web Toolkit files can be found with the APEX distributed files, under the apex/owa directory. The directory also includes a readme file that instructs you regarding installation.

Note

Bear in mind:

Similar to the AL32UTF8 issue, not using the correct version of the PL/SQL Toolkit will not stop the installation process and will not yield an error message. However, inappropriate (older) versions of the tool might create problems in generating the HTML code for the application pages. A typical error is when snippets of the HTML code itself appears on the page or the page doesn't include all its elements.
